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');
?>
|
Замечание:
$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();
?>
