$_id :
Horde_Form_Action_ConditionalEnable is a Horde_Form_Action that enables or disables an element based on the value of another element
Format of the $params passed to the constructor:
$params = array(
'target' => '[name of element this is conditional on]',
'enabled' => 'true' | 'false',
'values' => array([target values to check])
);
So $params = array('foo', 'true', array(1, 2)) will enable the field this action is attached to if the value of 'foo' is 1 or 2, and disable it otherwise.
factory(mixed $action, array $params = null) : \Horde_Form_Action
Attempts to return a concrete Horde_Form_Action instance based on $form.
| mixed | $action | The type of concrete Horde_Form_Action subclass to return. If $action is an array, then we will look in $action[0]/lib/Form/Action/ for the subclass implementation named $action[1].php. |
| array | $params | A hash containing any additional configuration a form might need. |
The concrete Horde_Form_Action reference, or false on an error.
singleton(mixed $action, array $params = null) : \Horde_Form_Action
Attempts to return a reference to a concrete Horde_Form_Action instance based on $action. It will only create a new instance if no Horde_Form_Action instance with the same parameters currently exists.
This should be used if multiple types of form renderers (and, thus, multiple Horde_Form_Action instances) are required.
This method must be invoked as: $var = &Horde_Form_Action::singleton()
| mixed | $action | The type of concrete Horde_Form_Action subclass to return. The code is dynamically included. If $action is an array, then we will look in $action[0]/lib/Form/Action/ for the subclass implementation named $action[1].php. |
| array | $params | A hash containing any additional configuration a form might need. |
The concrete Horde_Form_Action reference, or false on an error.
