Question

Is there any functionality that allow me do something like flash messages in cakephp? I don’t want to use session, because it shows flash message on the next page.

For example:
user type link with mistake mysite?action=mistake and i want to check in controller if there isnt mistakes like this so i have array with some actions which are allowed and i check if $this->params['url']['action'] is there. If it isn’t i want to show error to user , but this error shows only on second page (or if i reload). How can i avoid this?

The error you see is just a div with a concrete style. Something like:

<div id="flashMessage" class="error-message">Error</div>

What you could do is check with Javascript whatever you want to check and if it is not as expected, append the error div wherever you want.

That’s what I have dont in some forms to show the error in real time.

If you want something more elaborate you could try this:
