使用Yii更改CGridView中参数的值

I a have a basic question about CGridViews. I have the table employees stored in my DB and I am showing some of his atributs using this CGridView. The problem is that I stored all the passwords using the md5 codification, and when I want to show them I don't know how to show them without the md5 codification.

I tried it with the sentence: "'password'=>$dataProvider->employee->md5(password)," But as you can imagine it is wrong and it doesn't work. This is my CGridView with parameter password changed to this sentence.

<?php $this->widget('zii.widgets.grid.CGridView', array(
 'dataProvider'=>$dataProvider,
'id'=>'employee_list',
 'columns'=>array(
    'id',
    'name',
            //'password',
    'password'=>$dataProvider->employee->md5(password),
        array(
        'class'=>'CButtonColumn',
    ),
),
)); ?>

Somebody could help me? Thank you very much.

you just need to pass php code as string, Cgridview will run that string with eval function, Please refer following code for more clarification:

$this->widget('zii.widgets.grid.CGridView', array(
    'dataProvider'=>$model->search(),
    'columns'=>array(
            array(
                    'name'=>'password',
                    'value'=>'md5($data->password)',
            ),
    ),
)); 

Let say you encoded your password with base64_encode($password) then what you have to do is base64_decode($encoded_password)

from your question, is it $dataProvider->md5(password)?

maybe you can refer the code below.

$this->widget('zii.widgets.grid.CGridView', array(
    'id'=>'leaveapplication-grid1',
    'dataProvider'=>$model->searchpersonalleave($myid),
    //'filter'=>$model,
    'columns'=>array(

        'leave_dateapplied',
        'leave_id',
        array('name'=>'leave_category','value'=>'$data->getcategoryname($data->leave_category)' ), //0-annual, 1-medical, 2-emergency
        'leave_startdate',
        //'leave_enddate',
        'leave_duration',
        'leave_reason',

        array(
            'class'=>'CButtonColumn',
            'template'=>'{view}{update}',
            'buttons'=>array
                    (
                'update' => array
                        (
                    'visible'=>'($data->getupdatefunction(17) =="Yes")',
                       ),
            ),
        ),
    ),
));
