Yii find out id textfield?

Question

Yii

I create fields like this

for($i = 0; $i < count($rows); $i++)
                {
                    echo CHtml::label($rows[$i]['name'], $rows[$i]['name']);
                    echo CHtml::textField('elem[]','',array('id'=>$rows[$i]['name']));                  
                }

and in the controller

foreach($_POST['elem'] as $check)
                                    {
                                         $Ids = $_POST['elem'];
                                    };

so here i get

array(2) {
  [0]=>
  string(3) "231"
  [1]=>
  string(1) "4"
}

how to get field id?

Answer 1

You can find out on the frontend in your case with the help of some jquery.
No way on the backend, because you didn't pass the information by id in the form.
Names should be set like this:

$id = rows[$i]['name'];
echo CHtml::textField('elem[$id][]','',array('id'=>$id));
