            </tr>

        </table>

    </div>

</div>  

<?php

$this->endWidget();

Controller.php




public function actionAll() {

    $rs = $_POST['drpMinute']; //if comment this and print_r("hello"); it's work

    print_r($rs);

}

Update your action like


public function actionAll() {

    Yii::log('received', 'info', 'system.fucking.ajax.check');

    Yii::log(CVarDumper::dumpAsString($_POST), 'info', 'system.fucking.ajax.check');

    $rs = $_POST['drpMinute']; //if comment this and print_r("hello"); it's work

    print_r($rs);

}

Do not forget to update a config to get logs!

Then continue debugging

Not happen

Haven’t I told you not to forget to update your config??????

Do it like:


'log' => array(

                'routes' => array(

                        array(

                             'class'=>'CFileLogRoute',

                             'levels'=>'info',

                             'categories'=>'system.fking.ajax.check',

                             'logFile' => 'fk.info.log',

                         ),

				)

			),

Then post /protected/runtime/fk.info.log contents here.

I’m already set all but have not got log file.

Now I use Firebug tool(firefox plug-in).

I got this error. Why??




Undefined index: drpMinuts

try the $_POST["hour"]:

8

that work, but if I want to pass C_time value from drpMinute dropdownlist ajax how to reference C_time dropdownlist


 'data' => array('hour' => 'js:$("#C_time").value', 'minute' => 'js:this.value');

it’s not work

9

.val() instead of .value in the jQuery ;) , so:


 'data' => array('hour' => 'js:$("#C_time").val()', 'minute' => 'js:this.value');

and then $_POST["hour"] and $_POST["minute"] in the controller.

  • add id to the dropDownList:



<?php

echo $form->dropDownList($model, 'C_time', $this->HH(), array(

    'class' => 'input-small',

    'id' => 'C_time',

    'ajax' => array(

        'type' => 'POST',

        'url' => CController::createUrl('Customers/MM'),

        'update' => '#Customers_drpMinute',

        'data' => array('hour' => 'js:this.value'),

    ), 'multiple' => true,

    'style' => 'height:180px;'

));

?>

It’s work. Thank you very much.
