Just in case you’re not familiar with the basics, I suggest you read James Fairhurst’s and teknoid’s posts first. Good stuff but doesn’t work for Auth messages because you can’t specify parameters when Auth calls $this->Session->setFlash().
So I decided to ignore the phase where you set the flash message and hack the phase where the message is being printed. I created a custom helper and extended/overrode SessionHelper.
I basically took all code from SessionHelper->flash() up to where $layout is tested against ‘default’. Then I did my magic and called the parent or grand parent to do the real work.
I bet you know how to enable your helper in the controller (e.g. AppController), just don’t forget to add ‘Session’ too:
And here’s an example of the flash message layout (CakePHP 1.2). Notice that I refer to variable $id. I added it in my helper to mimic the original behaviour. Just as you’re used to you can access any variable that you set with $this->Session->setFlash() using the third argument. Also note that you can still choose a different layout using the second argument.
And here’s what you put into your main layout to print your flash messages:
