useful tidbit here – thank you.

i played around with Impromptu, a nifty jQuery extension, and got a nice modal message box that i put in my default.ctp attached to the body onload. funky. here’s the link to impromptu:

and here is the snippet i put in my template before the closing “>” of the body tag:

check(‘Message.flash’)): echo ‘onload=”$.prompt(\”; $session->flash(); echo ‘\’);”‘; endif; ?>

rock.

I did find your posting very useful, although i created my own helper class “Flash” for this one.
This was needed, because CakePHP is not able to put more then 1 Message of each category (error, success etc) in the SESSION.

So if your app throws a second error somewhere, the first one will be deleted silently, which is really a problem at some points!

I put them in an array, and therefore can store multiple ones, which are (by the helper) read out and displayed.

Next thing i wanna build in, is a sorted display. Not random, but in the order of importance: Error -> Warning -> Success -> Info

Thanks for this tutorial!

Oh and thank you Djize! I’ve been needing exactly that technique :-)
The elegant and “correct” way to do it.

connector, I'm using TinyMCE as the WYSIWYG editor. Enjoy!

Thanks for the nice tutorial. One question, can you tell my what wysiwy editor you used in the screenshots? Thanks!

Thanks for the article and the comment from Djiize. I now know how to use the Session->setFlash() funtion!

@leveille: or you can use the 2nd param of setFlash to specify a layout $this->Session->setFlash(‘bad values’, ‘flash_err’)
then create your layouts: flash_err.ctp, flash_warn.ctp, flash_succ.ctp
and just call $session->flash() in you default layout
Leave boring work to Cake, it exists for that ;)

I agree with your assessment that the use of the intermediate flash page intrudes into the normal application flow. I implement a technique whereby I create a flash element, and render this flash element at the top of my template.


element('flash');

The flash element consists of code to check whether or not the message being sent is an error, warning, or success:


   check('Message.err'))
      {
         echo '';
         $session->flash('err');
         echo '';
      }

   check('Message.warn'))
      {
         echo '';
         $session->flash('warn');
         echo '';
      }

   check('Message.succ'))
      {
         echo '';
         $session->flash('succ');
         echo '';
      }

I also make use of these div's for javascript feedback, which is why I don't programmatically display the actual div/class. They're always ready to be injected with user feedback. The p tags on the other hand are displayed when appropriate, as those are what get styled via css. In my controller I set the type of flash message and redirect to the appropriate location:


$this->Session->setFlash('The lesson you have selected is unavailable or invalid.  Please try again.', null, null, 'err');
$this->redirect(array('action'=>'index'));

Just thought I would share. This technique may or may not be helpful to others.
