Dropdownlist Optgroup In Formbuilder

Yii 1.1 General Discussion

Hello everyone!

I need your help, I am using the multimodelform extension to allow user pick many items (models) with their properties and then save them in models.

The problem I am having now is that I show a combobox and everything is fine, but dont know how to make a combobox with categories (as OPTGROUPS)

in the widget properties:


'formConfig' => $examen->getMultiModelForm(), //the form configuration array

then


public function getMultiModelForm()

{

$listaExamenes = Examen::getListExamen();

return array(

		  'elements'=>array(

			'examen_id'=>array(

				'type'=>'dropdownlist',

				'items'=>$listaExamenes,

                                'prompt'=>'Seleccione un exámen',

			),

		  	'cantidad'=>array(

		  		'type'=>'number',

		  		'min'=>1,

		  		'max'=>10,

//		  		'value'=>0,

		  	),

		));

}

and


public static function getListExamen() {

                $examenes = Examen::model()->findAll(array('order'=>'nombre', 'condition'=>'t.activo = 1'));

                return CHtml::listData($examenes,'id','nombre');

        }

I have two db tables

‘examen’ which contains all clickable items, and it has a foreign key ‘examen_tipo_id’ which refers to the table that categorize the items.

example:


table examen (id, name, foreign_key)

1 - item1 - 1

2 - item2 - 1

3 - item3 - 2



table examen_tipo (id, name)

1 - cat1

2 - cat2

Then, I want the combobox like

cat1

  • item1

  • item2

cat2

  • item3

I have seen examples in a form, but how to do it in a formbuilder mode?

thanks in advanced!

Dear Friend

We can construct the dropDownList in the following way.




$form->dropDownList($model,'name',CHtml::listData(Item::model()->findAll(),'id','name','brand.name')); //brand.name is going to group the items.

Here model Item has a realtion with model [b]Brand/b;

Regards.

Thanks for your response.

The problem is that the formbuilder (‘items’=>$listdata,) doesnt have $form, and in the method I am building it (getMultiModelForm) dont have $model

I dont know which $model type of object is (Item?)
