How do I print a message when opening a page, for example:
I'm on page Cliente/View and when I'm redirected to Nfe/index page, I want to print a message with instructions on what to do, pulling some data from Cliente/View .
I tried to use
$this->Session->setFlash('mensagem');
But I continued with no results, only the message is displayed when I return to page Cliente/View again.
For this same case, the following answer helped me, see it below:
When using setFlash , you can provide a key value, for example:
$this->Session->setFlash('This message is for form 1.', 'default', array(), 'form1');
Then you can print the flash above each form. It will only be displayed if the specified key has a value.
<?php echo $this->Session->flash('form1') ?>
