HTML_QuickForm_DHTMLRulesTableless

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).

Usage

To use this package you just need to do something like this:

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:

$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:

$form->getValidationScript();
