View source for Overriding JFormRules

{{review||Article needs structure and examples to be improved}}
To extend the rules that can be used by Joomla to validate form input, the following changes are needed:

== Step 1: Alter the controller ==

In the controller function add these lines:

<source lang="php">
$form	= $model->getForm();
$form->addRulePath(JPATH_COMPONENT.'/models/rules');
</source>

== Step 2: Add the rule files ==

In the folder models/rules in the component add any rule file you want to use.
