Hi

I have a question about validating group entries in quickform:

This is the example in the documentation:

$id[] = &HTML_QuickForm::createElement('text', 'username', 'Username');
$id[] = &HTML_QuickForm::createElement('text', 'code', 'Code');
$form->addGroup($id, 'id', 'Your ID:', '-');

// Validation rules per element

$rule['username'][] = array('Username is required', 'required');
$rule['username'][] = array('Username contains only letters',
'lettersonly');
$rule['username'][] = array('Username has between 5-8 characters',
'rangelength', array(5, 8));

$rule['code'][] = array('Code is required', 'required');
$rule['code'][] = array('Code contains numbers only', 'regex', '/^\d+$/');
$rule['code'][] = array('Code is 5 numbers long', 'rangelength', array(5,
5));

$form->addGroupRule('id', $rule);


But what am I supposed to do if I am dynamically adding elements such as
textboxes or textareas??? How can I make a rule for that.

Heres my example:


while ($row = $res->fetchRow(MDB2_FETCHMODE_ASSOC)) {
$skills[] = &HTML_QuickForm::createElement('advcheckbox', $row['skillid'],
null,'<b>'.$row['skillname'].'</b>',
'onclick="alert(this.form.elements.length)";
onclick="SetState(this,
this.form.elements['."'skills[txt".$row['skillname']."]'".'])"'
, $row['skillid']);
$skills[] = &HTML_QuickForm::createElement('textarea',
'txt'.$row['skillname'], $row['skillname'], 'disabled rows=3 cols=70');
}
$form->addGroup($skills, 'skills', 'Your requirements:', '<br />');



All that code adds x number of checkboxes and textareas.


Then:

$form->addGroupRule('skills', 'You need at least 1 requirement and explain
it', 'required', null, 1);


To make sure at least one checkbox is ticked before posting...


But I also want to make sure the text written in the textarea doesn't go
over 200 words. So how can I do that????


Please help!
