Conditional Drop down list Text value in Yii

I have a drop down list but I the text value is dependent on another value from the same model.

What I want to happen is if the row from a model has a client_type_id value of 1 then the drop down text should be company_name else it will be the first_name. Kindly refer to the code below.

<?php echo $form->dropDownListRow($model , 'client_id', CHtml::listData(Client::model()->findAll(), 'id', '$data->client_type_id == 1 ? $data->company_name : $data->first_name')); ?>

Is it even possible to achieve it like this?

PHP 5.3+ and Yii 1.1.13+

You can use an anonymous function:

echo $form->dropDownListRow($model , 'client_id', 
    CHtml::listData(Client::model()->findAll(), 'id', function($data){
        return $data->client_type_id == 1 ? $data->company_name : $data->first_name
    })
);

Yii < 1.1.13 and/or PHP <5.3

You can use the CActiveRecord::afterFind() method to initialize a variable say $list_info and use this as your field:

class MyClass extends CActiveRecord{
    public $list_info;
    ...

    public function afterFind(){
        $this->list_info=$this->client_type_id == 1 ? $this->company_name : $this->first_name
    }
}

The drop down list then becomes

$form->dropDownListRow($model , 'client_id', CHtml::listData(
    Client::model()->findAll(), 'id', 'list_info')
);
