Project hosting
by rainer - Jul 19th 2006 04:14:31
This project, like all others from this author, is hosted at
phpclasses.org, an absolutely obnoxious site which apparently only exists
to throw as much advertising as possible towards its users. Apart from
frequent pop-up windows and redirects, they require subscription for
downloading, openly announce that they will bombard every subscriber with
spam ('newsletters', as they call it), and make an extra effort to prevent
subscriptions with a disposable address from spamgourmet.com. Thankfully,
they don't know all domains for spamgourmet.

Re: Project hosting

I am afraid there are several misunderstandings here.
As the author of these classes, I can tell you that the service provided
by the site is wonderful. It keeps track of all users that download my
classes. When I release an update, an automatic newsletter is sent to my
class users to let them know about the changes, so they can be kept up to
data and always use the latest version with the newest improvements and bug
fixes.
If you do not want to receive the site newsletters, that is OK. You can
choose which newsletters you want to receive or not in the user options
page, or by sending an unsubscribe request to an address mentioned at the
bottom of each message.
Furthermore, when I release new classes, the site sends a newsletter
telling all users about it.
This is great because it provides extraordinary exposure to the work of
any developers that shares his PHP work in the site.
I don't know many other sites that help Open Source developers keeping so
many of their users so closely up to date.
I don't know either if you develop and share your work as Open Source. I
am sure if you would develop Open Source projects, you would appreciate the
service provided by the site.
Now, as developer of the site, I must tell you that if you do not like
advertising, I do not like it better.
Unfortunately it is a necessary burden to expose the users to the site
advertising. If it were not for that, the site would have been closed a
long time ago, like with all those .com sites that died because their
owners missed the fact that it is necessary to generate enough revenue to
pay for the site hosting, bandwidth and all the people involved in keeping
a busy like this up and running.
Fortunately, soon there will be an alternative to all those that do not
want to put up with the advertising. There is a package of premium services
being developed to be offered exclusively to subscribers that want to
adhere for a small monthly fee (say USD $5 or so).
Among other interesting
new services have been announced in the site blog, premium subscribers
will be able access the site without any advertising, have a better site
search, improved AJAX based user interface, etc..
These services have been developed very slowly because the current site
revenue is not enough to pay for additional staff.
Meanwhile there are already a few beta testers evaluating the new
services. If you are interested, you may submit a request to become a beta
tester, as it has been announce here.
It is impossible to please everybody, but at least I try to please the
users that really care about the site and want to benefit from thousands of
classes shared by hundreds of developers.
I hope you understand.

I am developing open source projects, and I certainly wouldn't
consider hosting them on this site, for the following reasons:
1. It is almost impossible to navigate the site. Almost every link
either pops up some ad, or redirects to a full-page ad that redirects to
the target page after some timeout. This is not the kind of site where I
would like to dwell for some time, looking around for goodies - rather it
is exactly the type of site that I wish to visit for the shortest amount of
time possible, and wish to leave as soon as possible. Let alone that the
ads are not even on topic.
I fully admit that there is a need for generating revenue by ads - google
does it, freshmeat does it, almost everyone else does it, too - but there
are obnoxious ways of advertising, and friendly/bearable ones.
phpclasses.org is one of the worst I've ever come to see. An important part
of good advertisement is the art of attracting users, instead of alienating
them.
2. You say that one can opt out of the 'newsletters'. Then why does
the site try to prevent signing up with a spamgourmet mail address? If I can opt
out anyway, the site shouldn't care. The only possible reason for caring is
the desire to collect valid email addresses (for spam?).
3.
If I want to be informed about updates to some software, I can always
subscribe to it on freshmeat. This is much nicer (because I can opt-in,
rather than having to opt-out of something I didn't ever want in the first
place).
4.
As a developer, I don't want to expose my users to a flood of junk ads,
and I also don't want to force emails down their throat. I'd rather prefer
if they have a pleasurable overall experience.

Trust me, the site puts advertising recommended by ad agencies like Google
AdSense, Fastclick, Tribafusion, etc.. It puts all the ads that you see
because it needs the revenue to survive. It is certainly not to annoy the
users, although it is impossible to not annoy some.
It is like free television channels. They are free, but you need to put up
with whatever advertising they present. You can subscribe to cable
television to get less advertising, but you still will get some channels
with advertising.
As I mentioned, the site will provide ad-free paid options similar to
buying a cable television subscription. Users that do not like advertising
will have that option. That is a good alternative to keep the site
viable.
It is pointless to complain that the advertising is not on-topic or you do
not like the way it is presented. I do not have the privilege to discard
most the advertising because the site would not survive without it.
If you have difficulty to understand this, maybe when you have a site like
this to maintain, you will be able to realize the things as they are, not
the way you wished.

It is nothing like that. Accepting subscriptions of users with disposable
addresses causes several problems.
Unfortunately it is too easy to create new accounts with disposable
addresses. That helps cheating authors to create new accounts to overrate
their packages and gain elicit exposure. In some cases they could gain
undeserved prizes like in the PHP Programming Innovation Award. This is
totally unfair to authors that really deserve to win.
Another problem is that most disposable address systems accept the
newsletter messages forever, even though no user will receive and benefit
from them. This makes the site waste bandwidth for nothing.
The site is on budget with hosting costs. To not raise prices the hosting
company has put a bandwidth cap. This means that the transfer rate is
limited.
When the site is serving too many pages or too many newsletters at the
same time, connections are put on hold and the Web site users will suffer
from site slow down.
Therefore, the site had to put on an effort to limit the bandwidth used by
sending the newsletters. Not accepting subscriptions of users with
disposable addresses was one of the measures.

As I said above, that is totally your problem. The PHPClasses site
provides a tremendous exposure to the authors work. The site has over
370,000 subscribers and is growing at a rate of about 10,000 new
subscribers a month. Of these near 150,000 receive new class alerts
newsletters at least once a week.
There are also the valuable prizes to the winning authors of the
innovation award can gain.
If you do not care about the benefits provided by the site, that is ok. As
I also mentioned it is impossible to please everybody. The site is focused
in pleasing those that care, while keeping itself financially viable. Any
reasonable human being can understand this.

Please don't put words in my mouth. I never said or meant that Freshmeat
is an inferior site. I was not comparing it to anything else. What I meant
is that nobody knows all sites, not even a great part of those that exist.
So, it is only natural that PHP classes site users and authors do not know
Freshmeat.
Furthermore, the purpose and scope of the sites is different. In the
PHPClasses site you can browse and download the PHP packages published
their. In Freshmeat you see only announcements about packages that are not
available here, but include other languages besides PHP, as well PHP
packages published in other sites.
Announcing packages in Freshmeat can always help authors letting others
know their work, regardless whether they published in the PHPClasses site
or not.

While people are able to stay reasonable and put pertinent questions
without intention to cause tumult and without departing to personal insult,
I can try to be patient and explain why certain things are not the way
those people think it should be. If your intention is just to throw more
flames just because you do not agree with the way the site operates, sorry
I cannot justify any further time to follow-up.

A great developer-friendly class
by powerobject - Jan 11th 2006 20:07:06
Oops! My earlier message got garbled and lost the <br>'s.
Hi Manuel,
Simply a 'great' class - very thorough and exhaustive to the detail
although one may not use each and every function from its API but who
knows? When you need a feature and you know it is there, it feels good and
that's what makes a software a success. Excellent and consistent coding
style. A developer-friendly class in that it does client-side as well as
server-side validations with a single configuration of the inputs whereas
other classes such as SmartyValidate, FormCat, etc. do either client-side
or server-side validations but not both. And to know it is over 5 years old
means it is almost bullet-proof. Includes most features that developers
look forward to using in their day-to-day coding which shows the author's
experience-level.
Here are a few suggestions:
Although descriptive, the title of the class is long and too generic:
Forms generation and validation. How about branding it with a short name
(no offense intended as the class itself rocks!)? Such as 'PHORM' or
'DynaForm' or 'DynaGen' or 'DynaValid' or 'PFGV' or 'FGV' or something
suitable (however, I'm not aware of existing trademarks). Branding makes a
product more popular and a domestic name.
Considering its 3500+ lines of code size, how does the class perform? Is
this class being used on any large/high-traffic/high-availability websites?
If not, is it possible to dish out a 'Lite' version skimping out some fat?
There are so many features in this class such as 'accessibility_tab_index',
etc. that every site may not use. On the other hand, support for Smarty is
refreshing and very much desirable to be retained.
Is there a way to implement features to configure changing the colors of
the field-labels and flashing a dialog with a consolidated message for
'all' the errors (with an optional Beep) on the form? It may be possible
with some plugin/custom functions but would be ideal to implement them
within the class. Here is an example:
http://www.softcomplex.com/products/tigra_form_validator/registration_form_validation.html
Date fields (dropdowns):
Prefer international format: [Year] [Month] [Day] (or is there a way to
shuffle them depending on the locale?)
With the above arrangement, the class can effectively and dynamically
filter the number of days in a month based on the Year and Month selection.
For instance, Feb (28), Leap Year (29), Sep (30) and Dec (31). This helps
in reducing lame data-entry errors as the code is self-correcting and
self-validating.
Date Range: In case of two date fields for a range of dates such as Date
of Arrival and Date of Departure (one >= the other), it would be
thrilling to have the second date field automatically filtering out the
invalid Years/Months/Days based on the Year/Month/Day selection in the
first date. For instance:
A person arrives on 2000/3/15 and departs on 2000/3/25. When the user
chooses the first date field as 2000/3/15, the Years in the second date
field should show only years that are >= 2000. Once the user selects
2000 in the second date field, the Months dropdown should show only values
>= 3; once the user selects 3 for the month in the second date field,
the Days dropdown should show only days >= 15 as it doesn't make sense
for someone to arrive after he/she departed (well, technically). Users
would get a kick out of such interface for it being intuitive, intelligent
and user-friendly which they experienced only in older client/server apps.
This feature would be in addition to the equality (password) and difference
(reminder) features. Is this something possible with
Connect()/linked-select?
Reserved Words: Some vars (error, form, etc) seem to be conflicting with
the reserved words of other interfaces such as Flash, Flex, etc. should the
developer want to pass values to those interfaces instead of HTML.
ResubmitConfirmMessage: Incorporate a feature to disable the Submit button
'OnSubmit' as default.
Email Validation: Are the validations/regex in this class adequate?

I could implement that but I do not have a good idea of how it could be
implemented in a straight forward manner.
I could associate an optgroup to an option value, but I am not sure how it
could define the menu hierarchy.
Do you have any suggestion?

Yes I agree it is a little complicated to ensure the logic is correct as
optiongroups can't be nested and you rely heavily on the user initiating
the class correctly.
One approach would be to create optiongroup array and use this to build
the select options instead. So you wouldn't have an OPTIONS index for the
AddInput function if the user chose to use optiongroups. (This should make
it easier to include into the existing code and help clean up the logic of
the optiongroups).
Each item in the array would contain an array of select options and if it
is an option group it will contain a label also. If an array doesn't have
a label then it is not inside an option group and can be directly outputted
as an option.
sudo code example.
$optionGroups = array();
$optionGroup[] = array("LABEL" => 'groupOne', "OPTIONS" =>
array(options););
$optionGroup[] = array("LABEL" => 'groupTwo', "OPTIONS" =>
array(options););
$optionGroup[] = array("OPTIONS" => array(options););
// Then when setting up the form input:
$myform->AddInput(array(
"TYPE"=>"select",
"NAME"=>"selectOptions",
"ID"=>"selectOptions1",
"SELECTED"=>$mySelectedOptions,
"SIZE"=>3,
"OPTGROUP" => $optionGroups;
));
Then when parsing the select option element, you would check if it has a
label, if so add optgroup tags and label the optgroup, loop the options and
then close the optgroup. If there is no label then the loop the options
and output.
Does that sound feasible / logical ?

I think this is a bit more complicated then I wanted.
The way I see the OPTIONS do not have their definitions changed when they
are grouped. So I think it would be better to let OPTIONS definition remain
as it is.
What can be added is the definition of the groups, associating a label to
the values of the respective options, more or less like this:
"OPTGROUPS"=>array(
"group1"=>array(
"value1",
"value2"
),
"group2"=>array(
"value3",
"value4"
)
);
What do you think?

That definately, would be the easiest option - the only problem I can see
is catching any errors if a user tries to add groups that aren't
chronological, or tries to nest option groups.
But, it would fit in nicely with the syntax of Select Options in your
class and I would happily use that approach.
Thanks

Coincidently, I was planning to implement it in January as part of a major
overhaul to the select input support. But feel free to develop whatever you
need for now.

Hi,
I just started using this class and I thik that is very useful and
flexible.
I have some suggestions:
first:
can add support of ID, STYLE and CLASS attributes in the LABEL
element?
it is very useful when the form are styled with a CSS.
second:
can add support of the ID attribute in the FORM element?
the XHTLM Strict not admit the NAME attribute in the FORM tag.

I can add support for that too, but you can use the class ExtraAttributes
variable to specify values that do not have built-in support.

Does This Class Work with Register_Globals = Off?
by Francis Chang - Oct 12th 2004 01:54:15
Hi,
I'm running Php 5.0 with Register_Globals = Off. I seem to have a problem
when calling the $form->WasSubmitted function. The function keeps
returning a null string even though the form was submitted previously. It
seems that the IsSetValue method makes uses of globals.
Is this class certified for Php 5.0 with register_globals off? If not,
any suggestions on how we might be able to make it work?
Thanks in advance for your input.

No, the IsSetValue function also checks the $_POST and $_GET variables, so
there is no reason for it not work as intended.
I suspect that you are not specifying a specific input name for the
WasSubmitted function to check and that makes it traverse all the form
fields to determine which submit button was used.
In this case, it only works if the submit inputs in your form set the NAME
attribute. Otherwise the class does not have a reliable way to determine
whether the form was submitted.
If this is your problem, just define the NAME attribute of your form
submit inputs.

Validate All Fields Regardless of Erros?
by Francis Chang - Oct 11th 2004 11:32:56
Hi,
First of all, great class!
I have to admit that I just started using this class and haven't spent a
lot of time with it. I have a general question to which I couldn't find
the answer in the documentation.
It seems that the class will stop validating on the server side once the
first error is found. Is it possible to have the server to continue
validating all the fields and return all the possible errors? This is
obviously a usability issue. If this is not possible, how difficult would
it be to extend the class to do so?
Thanks.

No, the class validates all fields when you call Validate. It returns the
error message associated to the validation rules that fails on the first
invalid field, but the verify array enumerates all fields that are
invalid.

Re: Validate All Fields Regardless of Erros?

Thanks Manual for your reply. To confirm my understanding,
The Verify array will enumerate all the fields that failed validation and
the error message that is returned will contain all the error messages (if
the field has multiple validation rules with multiple failures) that are
associated with the first field that failed validation? Is that
correct?

Server-Side Validation
by RossC0 - Jul 21st 2004 08:58:27
Hi,
First of all an excellent class! I have one question. How do I use the
ServerSide Validation, instead of client side?
I flagged the ValidateServerSideOnly on textbox array and I've set the
validation reg-ex and messages - however it still produces javascript
?!
Also with ValidateServerSideOnly do I use the set reg-ex to validate the
posted variable and then output the error message on the form - if so
how?
Kind regards,
Ross

Couldn't you have an AddFunction() call to set the form initial focus
input, or maybe set the ResubmitConfirmMessage class variable to prevent
submitting the form more than once?
These would lead to additional Javascript generation. If you do not have
any of these, please send me a minimal example script that exhibits the
problem.

I am not sure what you are asking. If you want to validate a field with a
regular expression just use the ValidateRegularExpression parameter,
regardless whether it will validate on the client side too or not.
Validation on the server side happens when you can the Validate function
of the class as you may see in the examples.

Re: Server-Side Validation
by RossC0 - Jul 22nd 2004 03:53:50
Hi thanks for your quick reply, I'm sorry I don't think I was very clear so
here is some sample code:
Heres a copy of my array set up:
$form->AddInput(array(
'TYPE'=>'text',
'NAME'=>'searchString',
'ID'=>'searchString',
'MAXLENGTH'=>100,
'ValidationOnlyOnServerSide' =>'Y',
'ValidateRegularExpression'=>'^[a-zA-Z0-9_]{1,100}$',
'ValidateRegularExpressionErrorMessage'=>'Please
enter valid search text',
'LABEL'=>'searchString',
'VALUE'=>$searchString
));
Ideally, what I want to do is catch any errors after the user has
submitted the form. I don't want javascript validation to be performed as
I really want more control on how the validation error messages are
displayed on page.
However, I do want to set up the reg-ex and the error message in the array
(as it keeps all the html item data together).
Is this approach possible with this class ?

Sure. BTW, I am working on a new version that lets you specify a new
Javascript function that is called when a fields does not validate on the
client side.
I don't know if that is what you want, but this feature allows you to
provide an alternative validation error notice, instead of using the
Javascript alert() message box that many people do not like. The new
feature will include a new plugin control for displaying messages in a
DHTML layer. I am still experimenting to verify the browser
compatibility.

Sounds great - one idea rather than using DHTML which has cross browser
issues and may be easier to code is (not sure though):
You could have a function that checks the returned posted variables
against any set reg expressions, this then returns the error message notice
if it fails, which in turn can be outputted on the page (or template) above
the field.
I think this approach is used in the old oohforms. It may be simpler than
the javascript DHTML method and would provide validation for javascript
disabled browsers, but on the downside it means that the page would have to
be re submitted.
Also would solve my problem as well ;-)

As I mentioned before, if it stills generates Javascript is due to other
reasons. If you can't figure yourself, I need to see your whole form PHP
script to tell you why it generates Javascript and what you need to do to
avoid it.

This class always did server side and client side validation. The client
side validation support is
optional. To perform server side validation, just call the class functions
LoadInputValues and Validate. Please read the documentation and the
supplied examples to understand better how it works.

As I made a fuss and was wrong before!! I thought I'd share a class
extension that sets the error messages as an array so you can output error
messages where desired on the page:
include_once 'forms.php';
class formsExtension extends form_class {
// Modified Validate Function - to return error messages in an
array.
Function Validate(&$verify,$sub_form="")
{
for($inputs=array(), $input_number=0,
Reset($this->inputs);$input_numberinputs);Next($this->inputs),
$input_number++)
$inputs[]=Key($this->inputs);
for($invalid_parents=$custom=array(),$error=array(),$input_number=0;$input_numberinputs[$field]["TYPE"],"custom"))
{
if(!IsSet($this->inputs[$field]["DiscardInvalidValues"]))
{
$input_error=$this->ValidateInput($field,
$this->inputs[$field]["VALUE"], $sub_form);
if(strlen($input_error))
{
if(IsSet($this->inputs[$field]["parent"]))
{
$parent=$this->inputs[$field]["parent"];
$invalid_parents[$parent]=$field;
$invalid_field=$parent;
}
else
{
$invalid_field=$field;
}
$error[$invalid_field] = $input_error;
$verify[$invalid_field]=$this->inputs[$invalid_field]["SubForm"];
}
}
}
else
$custom[]=$field;
}
for($input_number=0;$input_numberinputs[$field]["DiscardInvalidValues"]))
{
$input_error=$this->inputs[$field]["object"]->ValidateInput($this);
if(strlen($input_error))
{
$error[$invalid_field] = $input_error;
$verify[$field]=$this->inputs[$field]["SubForm"];
}
}
}
return($error);
}
function getErrorMessage($errorItem)
{
if (!$this->error_message[$errorItem])
{
return false;
}
else
{
$htmlOutput = "".$this->error_message[$errorItem].'';
print $htmlOutput;

I am not sure what to tell you because naturally I do not use QuickForm
myself.
Anyway, the Forms Generation and Validation class is now 5 years old and
so it matured a lot to meet the needs of many developers. Looking to the
page of Quickforms it seems it misses many features provided by this
class.
- Load submitted form field values even with register_globals option Off
and strip slashes when magic_quotes_gpc option is On.
- Keyboard navigation support:
* Attachment of labels with activation keys to each form field.
* Tab navigation order index.
- Security attack prevention by optionally discarding invalid values
passed in fields that could not be edited by users but may be spoofed by
attackers.
- Option to define a value that, when used in a field, it is accepted
without performing any of the validations defined for the field.
- Ability to stop the user from submiting a form more than once
inadvertdly.
- Sub form validation (validate only smaller set of field depending on the
submit button that was used).
- Composition and generation of the form HTML output with fields displayed
as fully accessible or in read-only mode.
- Generation of Javascript functions (useful to set to the page ONLOAD
event):
* Set the input focus to a field.
* Select the text of a field.
* Set the input focus and select the text of a field.
* Enable and disable input fields
- Automatic capitalization of the text of a field:
* Upper case.
* Lower case.
* Word initials
- Replacement of text field expressions to perform adjustments like
trimming whitespace or auto-complete values based on rules defined by
regular expressions
- Compose forms with templates using plain HTML files with embedded PHP
code or using the Smarty template engine with a supplied pre-filter
plugin
If you want to know about something more specific, just tell me about it.

Unfortunately that is not a viable idea. Basically the problem is that
some PEAR people do not want what they call "competing packages", so some
PEAR authors (the developers of competing packages) do all that can to keep
out other packages, even if those are better than what they have.
The coding guidelines are often used as an excuse to keep other people
packages. I use coding guidelines since many years ago, even before PEAR
was ever dreamed. The problem is that I use my own coding guidelines, which
are well defined and consistent, not the guidelines that a small group of
people of PEAR have chosen to be the ones and the only to be accepted.
It is not realistic to expect anybody that uses the same coding guidelines
for many years to change, just to be accepted in PEAR. It is like asking me
to stop writing with right hand, that I use for many years, and start using
the left hand instead, just because a small group of people decided that is
the correct hand to use. It should not matter what was the hand you used to
write good things, but PEAR people do not agree.
I am not the only one that does not agree with PEAR coding guidelines.
Many, many authors dislike PEAR guidelines, some are proeminent authors. I
recall that once Andrey Zmievsky (Smarty, PHP-GTK, etc..) said that "PEAR
coding guidelines make him cry". As a result you do not see packages like
Smarty as part of PEAR either.
Even if we agreed with PEAR guidelines, it would not be viable for many of
us, that hardly have time to do what we do, to convert thousands of lines
of our packages, just because they do not comply to PEAR guidelines.
But that is not the only problem about PEAR. For instance, once you submit
your packages to PEAR, other people can mess your code with prior consent
or agreement. That is disrespectful and hateful. Basically you loose
control as if you no longer own the copyright of your code. Open source and
loosing copyright is not the same thing. I do not object people using
changed versions of my code, but I object people making changes that I did
not agree to my projects in my main work repository. It is hard enough to
keep up with the complexity of my projects, even more with a bunch of
people messing with the code. Too many cooks spoil the broth.
Other than that, you do not have freedom to use whatever free software
license you want to distribute your code. For instance GPL packages are
banned in PEAR, and LGPL is discouraged. Personally I always use BSD
license, so that would not be a problem for me, but it would be a problem
for other authors that do not agree.
Originally, PEAR was expected to be CPAN for PHP, but AFAIK Perl CPAN does
not impose such restrictions.
This forms class and all or my classes are distributed in the PHP Classes repository. It is a
package repository site that exists for more time than PEAR. It is
certainly more popular according to Alexa site popularity rankings.
The PHP Classes site is much more focused in providing satisfaction to the
authors that contribute to it. Therefore it has certain important features
that PEAR does not have.
The PHP Classes site has now 250,000 subscribers, about half of those
remain active in the site. This means that whenever you release a new
class, about 120,000 users, eager to learn about new classes, are notified
by e-mail about the new class. This is an extraordinary way for the class
authors to get immediate exposure for their work.
The PHP Classes site keeps track of all the downloads of all classes. When
a class is updated, the users that downloaded it are notified by e-mail
about the new release, except for those that do not want e-mail
notifications. This helps authors to keep their users upto date using the
latest versions, so they do not have to waste time providing support to
people using outdated versions, just because they were not aware of the
updates.
The download records are accurate. This allows the authors to know how
many unique users have downloaded a class. The site can also build top
download and top rated charts that are immune to fraud, so every author
gets an equal chance for being recognized for the value of the classes that
he is sharing.
There are other things that the PHP Classes site provides that PEAR
doesn't. I do not have anything against those that contribute to PEAR, but
unfortunately PEAR does not represent a consense among the PHP community,
unlike for instance what CPAN represents for the Perl community.

This is just a class the validates and outputs HTML forms. You can build

For integration with databases, you may want to try this database access
class or use this e-mail message

The class always validate the select inputs to verify that the selected
values is one of the options list. So, if some hacker submits a form with
invalid selected option, the class Validate function detects that. The
input ErrorMessage definition argument specifies the error message that is
returned.

Sorry, but how to validate if I want user to select only one option in a
drop down list (they have to select only one option) and the drop down
attribute IS NOT 'MULTIPLE => 1'. I've been trying to use

As I said, you do not have to do anything because the class Validate

// unset selected value form class
_F.reminder.options[0].selected = false;
// create new selected value with undefined value
_F.reminder.options[_F.reminder.options.length] = new Option( "[Select

This is not accepted. You need to specify an associative array for the
options. Also, you cannot have a simple select input without selecting an
option. AddInput function would not add the input and return an error.
What you want to do can be achived like this:
$form->addInput(array(
"TYPE" => "select",
"NAME" => "reminder",
"ID" => "reminder",
"LABEL" =>"Reminder"
"VALUE" =>"",
"ValidateAsNotEmpty" =>1,
"ValidateErrorMessage" =>"You have not selected a valid reminder
option.",
"OPTIONS" => array(
""=>"Please select a reminder",
"0"=>"a",
"1"=>"b"
)
));

The AddInput function returns an error when it fails. Just echo that value
and you will understand what is wrong.

How would I turn of client side validation completely? I saw nothing in
the manual or documentation about this.

Currently you can just specify the ValidateOnlyOnClientSide argument per
each field that you do not want to validate on the client side.

Is the output of created forms adjustable
by Wookkie - May 30th 2003 02:52:33
Hi i am new to this forms-generation.
It seems to it it is really more powerful than a self written
Form-Script.
I use Smarty and also i like the use of css.
So my intention is to format the output of the non-Javacript-validation by
css.
After the form is submitted i prefer to have the non validated formfields
shown in another css-class.
Another design-thing is that i prefer to otupot the error-messages shown
as alt-tags behind a icon-Graphic behind each form-field.
i don't know if this this possible and like to know if this is a difficult
thing before i work deeper into this class and, in the end, see that these
things probably didn't work.

Yes, you can either specify input style attributes with either the STYLE
or the CLASS arguments of the AddInput function.
If you want to change the STYLE or CLASS of an input field that is not
valid, you can use the SetInputProperty() function for that after calling
Validate().

Sure, you mark invalid fields with whatever HTML code you want.

validate as group
by Conrad - Apr 28th 2003 05:59:09
Hallo,
thanks for your class, it is very helpful.
Is it possible to group inputs, e.g. of select and text type, in such a
way, that I can validate whether only one of them contains a value while
the other does not? So far I have only been able to create a workaround
using a client javascript function and similar input names.
Cheers,
Conrad

There is the SubForm attribute that can be used to group fields, so when
you submit a form with a submit button of the same SubForm, it will only
validate the fields of the same SubForm.
There is also the ValidateOptionalValue that makes the form only validate
fields that are different of the specified value.
I am not sure if this is what you want.

Bugs when using Smarty {include} capability
by berendes - Feb 18th 2003 21:22:16
forms.php isn't completely compatible with the Smarty {include} capability
(nested templates).
I haven't tested this thoroughly, but this is what I've noticed.
1. if f1.tpl {include}'s f2.tpl, and f2.tpl has no {input} commands, php
generates a fatal error (For instance: Call to a member function on a
non-object in /.../templates_c/%%-84/%%-846696630/f2.tpl.php on line 186)
after seemingly rendering all of f2.tpl correctly.
Workaround: put a dummy {input} command at the end of f2.tpl (perhaps
elsewhere as well, haven't tested).
2. If f1.tpl {include}s f2.tpl, like so
...html and formsgen code ...
{input name="somefield"}
...more generic html and smarty code...
{include file="f2.tpl"}
then f1.tpl is rendered as if it had been written:
...html and formsgen code ...
{input name="somefield"}
{include file="f2.tpl"}
...more generic html and smarty code...
I.e. the include'd code is inserted in the wrong place.
Workaround: put a dummy {input} right before the {include} command, and it
stays put, e.g.
...html and formsgen code ...
{input name="somefield"}
...more generic html and smarty code...
{input name="dummy"}
{include file="f2.tpl"}
seems to render as expected.

Can you give me the smallest example that presents this problem?

Recovering values for select, multiple fields?
by berendes - Jan 24th 2003 13:58:28
When I define a select/multiple field in the test_smarty_form, like so:
$testform->AddInput(array(
"TYPE"=>"select",
"NAME"=>"MatchingFundType",
"ID"=>"MatchingFundType",
"SIZE"=>"9",
"MULTIPLE"=>"1",
"OPTIONS"=>array( "community"=>"community", "ecdev"=>"economic
development", "empworkdev"=>"employment"),
"LABEL"=>"Check one or more categorical
<u>s</u>ources of matching funds",
"ACCESSKEY"=>"s"
));
I don't get the values out of the submission automatically. Am I missing a
trick, or do I have to use the Changes property specifically to extract
info from select/multiple fields? (or some other way)?

Use GetInputValue() function. For SELECT MULTIPLE fields it will return an
array with all selected values.

GetValue & Select/Multiple & magic_quotes_gpc interact badly
by berendes - Jan 30th 2003 12:38:18
I think I've found the disconnect. The GetValue function in forms.php has
this near the end:
> if(function_exists("ini_get")
> && intval(ini_get("magic_quotes_gpc")))
> $value=StripSlashes($value);
so if the GPC value being retrieved is an Array (like a Select/Multiple) ,
StripSlashes will return "Array", rathern than array ("option1",
"option2").
and you won't see this behavior unless you've got magic_quotes_gpc set.

love it, need help with validateasset
by berendes - Dec 20th 2002 15:35:48
THis could work well for us - thanks
(1) looks like "validateasset" does not work with <input
type=checkbox name=chesspiece value=knight> <input type=checkbox
name=chesspiece value=queen> construct to ensure that at least one is
checked. is that right?
(2) not clear how "validateasset" should work for a type=select.
both versions (smarty and not) of the test form show a validate for credit
card type, but it looks like you can leave it set to unknown, and php won't
complain.

No. Custom validation logic should be handled with custom validation
functions.

If you do not want to accept unknown credit card type, change it to
undefined and make it value be an empty string. Then use
ValidateAsNotEmpty.

How to make it work with register_globals=off
by MortenT - Nov 10th 2002 20:44:17
Hi there
Just to let you know out there...
Put this in the top of the page or somewhat near the
top.
foreach ($HTTP_POST_VARS as $k=>$v) {
$tmp = $k;
$$tmp = $v;
}
.. and change this..
$f->LoadInputValues($f->WasSubmitted($doit));
.. to this...
$f->LoadInputValues($f->WasSubmitted($tmp));
and change this ..
if ($f->WasSubmitted($doit))
.. to this...
if ($f->WasSubmitted($tmp))
And everything works...
I got it from Vinay Kumar who posted it at the website
for OOHForms
Bedst regards
