[string
$name = null], [string|array

HTML_QuickForm2_Element_Hierselect::__construct(): Class constructor

HTML_QuickForm2_Element_Date::__construct(): Class constructor

HTML_QuickForm2_Element_Static::__construct(): Class constructor

HTML_QuickForm2_Element_Select::__construct(): Class constructor

HTML_QuickForm2_Element_InputFile::__construct(): Class constructor

HTML_QuickForm2_Element_InputCheckable::__construct()

HTML_QuickForm2_Element_InputCheckbox::__construct()

array	`$data`	—	Element data (label, options used for element setup)

HTML_QuickForm2_Node addFilter(
callback
$callback, [array
$options = array()])

Adds a filter

A filter is simply a PHP callback which will be applied to the element value when getValue() is called.

Return: The element
Throws: HTML_QuickForm2_InvalidArgumentException If callback is incorrect
Access: public

Overridden in child classes as:

HTML_QuickForm2_Element_InputFile::addFilter()

Parameters:

callback	`$callback`	—	The PHP callback used for filter
array	`$options`	—	Optional arguments for the callback. The first parameter will always be the element value, then these options will be used as parameters for the callback.

[ Top ]

HTML_QuickForm2_Node addRecursiveFilter(
callback
$callback, [array
$options = array()])

Adds a recursive filter

A filter is simply a PHP callback which will be applied to the element value when getValue() is called. If the element value is an array, for example with selects of type 'multiple', the filter is applied to all values recursively. A filter on a container will not be applied on a container value but propagated to all contained elements instead.

If the element is not a container and its value is not an array the behaviour will be identical to filters added via addFilter().

Return: The element
Throws: HTML_QuickForm2_InvalidArgumentException If callback is incorrect
Access: public

Overridden in child classes as:

HTML_QuickForm2_Element_InputFile::addRecursiveFilter()

Parameters:

callback	`$callback`	—	The PHP callback used for filter
array	`$options`	—	Optional arguments for the callback. The first parameter will always be the element value, then these options will be used as parameters for the callback.

Return: The added rule
Throws: HTML_QuickForm2_NotFoundException if class for a given rule name cannot be found
Throws: HTML_QuickForm2_InvalidArgumentException if $rule is of a wrong type or rule name isn't registered with Factory
Access: public

Parameters:

mixed	`$options`	—	Configuration data for the rule
int	`$runAt`	—	Whether to perfom validation server-side and/or client side. Combination of HTML_QuickForm2_Rule::SERVER and HTML_QuickForm2_Rule::CLIENT constants
