Hello,

I am creating my module in which there is a form with scrollbar list.
The xoopsFormValidate function test an empty string with the operator == \"\".
how to do to test the backspace in the string ?
The xoopsFromValidate is defined inside class XoopsThemeForm.
An idea ?
Best regards

Tonyboy

xoopsFormValidate function is a javascript function.
It is used when the form is actually displayed.

is there an option to do a server-side check than having us do our own validation?

ex
FROM
if (!empty($_POST['email']) && !empty($_POST['title']) && !empty($_POST['address']))
{
 // save to db
}
else
{
 $errors = array();
 if (empty($_POST['email']) {$errors[] = 'Missing Email';}
 if (empty($_POST['title']) {$errors[] = 'Missing Title';}
 if (empty($_POST['address']) {$errors[] = 'Missing Address';}
 $xoopsTpl->assign('errors',$errors);
}

TO
if ($form->validate($_POST)) // or $_GET wherever the data is coming from
{
 // save to db
}
else
{
 $xoopsTpl->assign('errors',$form->errors());
}


We would have all the form assignments (addElement()) at the top

Not yet, but I have already redone all this layer in the CVS repository, and it will be possible in 2.1+
$form->loadValues( $_POST );
if ($form->validate()) {


Not far...

Thanks skalpa. For those who just can't wait, I've developed my own (simplistic) validation function

Source
/**           
* @author zer0fill, Sun Aug 08 02:34:28 PDT 2004       
* @desc Validates required input fields. Returns a preformatted string if there's an error     
* @return string|null        
* @param array $required (key=name / value=displayed error)         
*/ 
function validate($required)
{
    // prep the error message, if any    
    $message ='';
    // setup a loop on each required field than doing it manually line by line    
    foreach ($required as $key=>$item)
    {
      // find the missing required fields (javascript disabled on user's end)
      if (empty($_POST[$key])) {$message .= $item.', ';}
    }

    // A missing field was detected
    if (!empty($message))
    {
      // setup the error message and remove the trailing `, `
      $message = 'Missing Required Field(s): '.substr($message,0,-2).'
';
      return $message;
    }
}


Example
$required = array( 'office_id'=>'Office'
                      ,'role_id'=>'Role'
                      ,'type_id'=>'Type'
                      ,'title'=>'Title'
                      ,'fname'=>'First Name'
                      ,'lname'=>'Last Name'
                      );
    $errors = validate($required);
    if (empty($errors))
    {
      // save to db
    }
    else
    {
      $xoopsTpl->assign('errors',$errors);
    }


Output
<div class="errorMsg">Missing Required Field(s): Office, Role, Type, Title, First Name, Last Namediv>


BTW, did you also make regex checks like proper phone format inputs, email, at least x chars, etc (kinda like PEAR's $form->addRule()) ?

Yep...
There's already Required / Length / Regexp, and you can make your own validators.
In fact, I could say our framework will be some kind of a mix between the 2.0 classes and PEAR::QuickForm (at least feature-wise, I recoded everything as I think both overuse get/set methods, which I dont like considering we're using PHP).
- You'll be able to modify ALL the elements attributes
- There's the validators stuff implemented
- I'm thinking about adding some of the QF custom elements, although this hasn't been done yet (@ least the "Advanced checkbox", and maybe others, like the "autocomplete" input control)
- You'll be able to attach an object to a form (well, the reality is going to be a bit longer than the following sample, but I think you'll get the point)

$form->attachObject( &$source );
$form->loadValues( $_REQUEST );
if ( $form->validate(true) ) {
    $handler->update( $source );
}
