Problems with Checkboxes after Dropdownlist

Yii 1.1 General Discussion

I have some problems with a dynamic list of checkboxes. I want to Update a list of checkboxes dependent on the dropdownlist.

I’ve tried something like that (and followed the Dropdown->Dropdown Article in Wiki):

View:




<?php 

echo $form->dropDownList(

    $model,

    'item_id',

    $model->getItems(),

    array(

    	'ajax' => array(

		'type'=>'POST',

                'url'=>CController::createUrl('controller/dynamicCheckBox', array('id'=>$id)),

		'update'=>'#selector',           

        ),

    	'prompt' => 'Select',

    )

); 

echo CHtml::CheckboxList(

    'selector',

    array(),

    CHtml::listData(

        Items::model()->findAll(),

        'id',

        'name'

        ),

    )

);

?>

The action in the controller




public function actionDynamicCheckBox()

    {


        for ($i=0; $i<= count($wantedListOfItems)-1; $i++) {

            //echo CHtml::checkBox('name', true, array('id'=>'selector_'.$i));            

            echo CHtml::tag('input',

                   array('checked'=>'checked','id'=>'selector_'.$i,'type'=>'checkbox'),false,true);

    }

it outputs something on the console, which looks like the HTML code I want, but the Update of the existing checkboxes doesnt work.

I would be happy if you could help me.

In the API:

CheckBoxList Detail

You are specifying you want ‘#selector’ to be updated.

Your code generates a check box list with name ‘selector’, not id.

Add array(‘id’=>‘selector’) to your CheckBoxList! ::)

I can’t get it to work. Do you have a working example?

Maybe I should not render the checkboxlist in the first place, only after selecting in the dropdownlist.

I was frustrated, so I used <div> tags for grouping and update the <div> content. Less confusing for me :)

Hi.

I know it is an old post but I’m also trying to do a checkboxlist which depends of a dropdownlist and I don’t really understand how to do it. :unsure:

Have you created an empty <div> with the id ‘selected’? Or placed your checkboxlist inside a <div> with the id ‘selected’?

like this?




echo CHtml::CheckboxList(

    'selector',

    array(),

    CHtml::listData(

        Items::model()->findAll(),

        'id',

        'name'

        ),

    array('id'=>'selector')

);

Thanks!
