CJuiDialog page redirect

[muranaka]

I am trying to implement a password reset page. After the password is reset i want it to display a dialog saying the email was sent then redirect the page to the login screen the the dialog is closed.

Here is what have for the dialog and redirect:

$this->beginWidget('zii.widgets.jui.CJuiDialog', array(

						'id'=>'mydialog',

						'options'=>array(

						'title'=>'Email Notification',

						'autoOpen'=>true,

						),

					));

					

					echo "Email has been sent!";

					

					$this->endWidget('zii.widgets.jui.CJuiDialog');

					

 					$this->redirect(Yii::app()->createUrl('site/login'));

When the user hits submit to start the password reset function it displays this error page:

Cannot modify header information - headers already sent by (output started at /Library/WebServer/Documents/yii/framework/zii/widgets/jui/CJuiDialog.php:73)

Does anyone know how to fix this? also is there a way to add an ok button on the dialog so when they click ok then it redirects to the login screen?

Thanks

the CController::redirect() use header() function

Remember that header() must be called before any actual output is sent, either by normal HTML tags, blank lines in a file, or from PHP. It is a very common error to read code with include(), or require(), functions, or another file access function, and have spaces or empty lines that are output before header() is called. The same problem exists when using a single PHP/HTML file.

you can use javascript to redirect

like this

$("form").submit(function() {

   //open the dialog

   $("#mydialog").dialog("open");

   //redirect

   window.location = XXX;

   //$.ajax()

   return false;

});

I just debugged a similar problem.

It turns out that when calling the widget directly from the controller, its output does not get captured and directly goes to the output stream.

So the solution is to put it in a view and render the view (this will capture the output so the header statements will take effect before the "print" actually goes to the output stream.
