Hi LostCoder,

What is it that you want to ask help for regarding CHtml::dropDownList? Your statement is kinda vague, and there are lots of possible response to it. Kindly narrow down your concern, or at least ask a straight forward question so we can help you more effectively.

Anyway, here is the class reference for dropDownList.

i would just like to ask for a help to display my list of countries from database to a Chtml::dropdownlist.

// in action

$this->render('action_view', array(

  'countries' => Country::model()->findAll(),

));


// in view (if you have no form)

<?php echo CHtml::dropdownlist('select_name', '<selected value>', CHtml::listData($countries, 'id', 'name'));?>


// in view (if you have form defined, e.g. for change user country)

<?php $form = $this->beginWidget('CActiveForm', array(

	'id'=>'user-form',

	'enableAjaxValidation'=>false,

)); ?>

...

<?php echo $form->dropDownList($user, 'country_id', CHtml::listData($countries, 'id', 'name'));?>

..

// close form tag

<?php $this->endWidget(); ?>

Hi please note that dropdownlist expects an array in the following format:

array(‘1’=>‘one’, ‘2’=>‘two’)

can you please explain how you generate the array that you use in your dropdownlist?
