Class Details

[line 152]
Handles a Container that can be repeated multiple times in the form

This element accepts a Container (a Fieldset, a Group, but not another Repeat) serving as a "prototype" and repeats it several times. Repeated items can be dynamically added / removed via Javascript, with the benefit that server-side part automatically knows about these changes and that server-side and client-side validation can be easily leveraged.

Example:

 $group  = new HTML_QuickForm2_Container_Group()

 $repeat = $form->addRepeat('related');
                ->setPrototype($group);
 // repeat indexes will be automatically appended to elements in prototype
 $group->addHidden('related_id');
 $group->addText('related_title');
 // this is identical to $group->addCheckbox('related_active');
 $repeat->addCheckbox('related_active');
 
 // value of this field will be used to find the indexes of repeated items
 $repeat->setIndexField('related_id');

Method Detail

__construct (Constructor) [line 224]

HTML_QuickForm2_Container_Repeat __construct(
[string
$name = null], [string|array
$attributes = null], [
$data = array()])

Class constructor

Repeat element can understand the following keys in $data parameter:

'prototype': a Container to be repeated. Passed to setPrototype().

Access: public

Overrides HTML_QuickForm2_Node::__construct() (Class constructor)

Parameters:

string	`$name`	—	Element name
string\|array	`$attributes`	—	Attributes (either a string or an array)
array	`$data`	—	Additional element data

[ Top ]

appendChild [line 276]

HTML_QuickForm2_Node appendChild(
HTML_QuickForm2_Node
$element)

Appends an element to the prototype container

Elements are kept in the prototype rather than directly in repeat

Return: Added element
Throws: HTML_QuickForm2_InvalidArgumentException
Access: public

Overrides HTML_QuickForm2_Container::appendChild() (Appends an element to the container)

Parameters:

HTML_QuickForm2_Node $element — Element to add

[ Top ]

appendIndexTemplates [line 466]

void appendIndexTemplates(
)

Appends the template to elements' names and ids that will be later replaced by index

Default behaviour is to append '[:idx:]' to element names and '_:idx:' to element ids. If the string ':idx:' is already present in the attribute, then it will not be changed.

Checkboxes and radios may contain ':idx:' in their 'value' attribute, in this case their 'name' attribute is left alone. Names of groups are also not touched.
