HTML_QuickForm_DHTMLRulesTableless is a DHTML replacement for the standard
JavaScript alert window for client-side validation of forms built with
HTML_QuickForm when using the HTML_QuickForm_Renderer_Tableless
renderer.
In addition to the standard behaviour of HTML_QuickForm
(i.e. showing the errors from client-side validation
on the "onSubmit" event),
this package can also show the errors
on the "onBlur" and "onChange" events
(see below for information on how to enable this).
To use this package you just need to do something like this:
<?php
require_once 'HTML/QuickForm.php';
require_once 'HTML/QuickForm/DHTMLRulesTableless.php';
require_once 'HTML/QuickForm/Renderer/Tableless.php';
$form = new HTML_QuickForm_DHTMLRulesTableless(...);
$renderer = new HTML_QuickForm_Renderer_Tableless();
// usual code, e.g. new form fields, rules, ...
$form->accept($renderer);
echo $renderer->toHtml();
?>
|
As already said for the tableless renderer,
you need to add the following line to your code
to get full XHTML validity:
<?php
$form->removeAttribute('name');
?>
|
Note:
$form
can be used the same way as with the standard
HTML_QuickForm package,
there is no difference.
To enable validation on "onBlur" and "onChange" events,
you need to add the following line before the
$form->accept($renderer); call:
<?php
$form->getValidationScript();
?>
