I am using cakePHP v1.26. In the default.ctp file, I got a single of this code in it:
$session->flash();
I came a corss a web site in which the author suggested using this instead:
if($session->check('Message.flash')){
$session->flash();
}
I do not understand what this line of code is doing:
if($session->check('Message.flash')){...}
what is "Message.flash" in this case?
Is "Message.flash" a custom variable or
a built-in varibale which has been predefined in cakePHP?
Message.flash
is the session variable name. It will be defined by cakephp, when you use $this->Session->setFlash('Your message');
from your controller.
if($session->check('Message.flash')){...}
checks, if session Message.flash
, which contains the flash message, exists.
