Zend Form :: ‘Multiple Select box’ and ‘Option Group’

Hello Friends,

Multiple Select box in Zend Form using Zend Framework:
I got a scenario in which i was to put drop down with ‘multiple’ option enabled. I am using Zend_Form so  definatley i was in search of some Zend framework provided controll to create it,
i found following  way to create ‘Multiple Select box’ using Zend_Form in Zend framework:

$techDoc = new Zend_Form_Element_Multiselect(‘docs’);
$techDoc->setLabel(‘Technical Documents’)
->setMultiOptions(array(“1″=>”option1″ ,”2″=>”option2”));
$techDoc->size = 5;
I used  Zend_Form_Element_Multiselect to creat ‘Multiple Select box’ so it is very simple 😉 .

First parameter ( $techDoc->setLabel ) will set the Lable of this drop down and second parameter setMultiOptions expects [Associative] array of options that this drop down will have.

Last thing was $techDoc->size that helps to choose size of this Multiple select box.

In following  section, i’ll enhance this example and will try to explain how i achieved ‘Option Group’ in multiselect drop down. (you may also use the following scenario to create ‘Option Group’ in Zend_Form_Element_select that creates simple drop down)

Multiple Select box with ‘Option Group’:

$techDoc = new Zend_Form_Element_Multiselect(‘technical_doc’);
$techDoc->setLabel(‘Technical Documents’)
->setMultiOptions(array(“Option Group 1” => array(“option1″,”option2″,”option3”),
“Option Group 2″=>array(“option1″,”option2″,”option3”)));
$techDoc->size = 5;

so Array of associative arrays generate ‘Option Group’ that was looking very hard to me 🙂 ,

Hope you’ll find it inofrmative …
