Flash Messenger Bug in Zend Framework + Patch

Arrgh am I going mad.. could something so simple really not work..?

It turns out that I wasn't going mad, and Flash Messenger in Zend Framework really does have a bug. If its not working for you, the following patch may well fix things. You can check if this bug applies by setting your error reporting to E_ALL in your bootstrap.

If you get the following error message then this patch should fix things for you.

PLAIN TEXT
CODE:
  1. Notice: Indirect modification of overloaded property Zend_Session_Namespace.....

To fix this problem and get FlashMessenger working correctly, you need to edit library/Zend/Controller/Action/Helper/FlashMessenger.php

find this line

PLAIN TEXT
PHP:
  1. self::$_session->{$this->_namespace}[] = $message;

and replace with this block

PLAIN TEXT
PHP:
  1. //self::$_session->{$this->_namespace}[] = $message;
  2. $sessionMessages = self::$_session->{$this->_namespace};
  3. $sessionMessages[] = $message;
  4. self::$_session->{$this->_namespace} = $sessionMessages;

Apparently this issue only affects php 5.2 and so they have decided not to fix it and instead suggest upgrading the PHP version. If you need to get it working though the above will fix it for you.

Someone give this man some money!
 

[...] The messages array was always empty, no error message, nothing. I asked the big G again and I found this article. As you will notice this article was written in may 2009, so more than a year [...]

I'm pretty sure this is a session bug in PHP version 5.2.1 (and below) and not so much a bug in the helper itself. Still, this is a solid fix. Thanks!
