Topic: ZF: Controllers Showing Up Blank

[Swamp56]

I've been making a forum system with Zend Framework for a little while now (I originally used my own OOP framework, but decided this was easier ).

Ok, so I extended the Zend_Controller_Action class and made my own version, as is shown here.

If you notice, I have instantiated a class called Messages, which is for the private message system that I'm creating. The issue is that when I instantiate that, everything goes blank; I can't access any controllers. The code for that class is here. Please note that it's a bit messy at the moment as I'm not even close to being done with it.

I have tried emptying the class by having no functions to no avail. I can't figure out what the hell is going on that would make all of my controllers blank. I checked the source and there's nothing as well. I have asked fellow programming friends and they were stumped too.

Any help is greatly appreciated  !

You likely have a fatal parse or fatal runtime error. You should be learning php, developing php code, and debugging php code on a system with error_reporting set to E_ALL and display_errors set to ON to get php to help you with errors it finds. Those two settings must be set before your code is parsed in order to help show fatal parse errors because you code is never executed in that case.

And not many people are going to visit links you put in your post. If you want someone to examine your code you will need to post it in the forum.

I've done both of those things as well as allow ZF to throw exceptions in case of any error.  Here is the code that I linked:

/application/usr/models/Controller.php

$this->messages = new Messages;

// Retrieve variables from index 
$this->smarty = Zend_Registry::get('smarty');

// Register permissions if a user is set
if (isset($this->session->info->user_id))
{
$this->permissions = $this->users->returnUsersGroupPermissions($this->session->info->user_id);

// Make sure the class returns the permissions as an array and not null
if (is_array($this->permissions))
{

}
}

}
}
