Zend Framework Action Gets Called Twice

we are trying to build an application using the zend framework and have the following problem: "Some controller actions are called twice. This means that the actions gets called, finishes its execution and then gets called again".

We tracked this down by checking entries in a log file. For one request there where 2 entries in the log file.

Do you know anything that might be causing this problem? Is this related with the dispatch process of the Front Controller?

Regards,

I'm using Chrome 17.0.x, Webug and Zend Framework 1.11.1 and still seeing this issue. I disabled Webug as suggested and the Action was only called once.

So, I think this is a bug in Webug.

I found out that action got requested twice when Chrome Extension Webug (FirePHP extension for Google Chrome) was enabled.

We were having a similar problem. Some actions were executed twice. After much debugging and googling, found out the problem was a bug in ZFdebug. Installed this patch and everything went back to normal. Hope this helps someone else.

try and use a debugger ( XDebug for example ) to see how your code is runned. focus on the dispatcher, something must have happened and the request action is not set as dispatched so it gets runned again.

It might be a bug. Difficult to tell without more information.

Try logging a backtrace each time the action method is called.

<?php
trigger_error(var_export(debug_backtrace(), true));
trigger_error(var_export($_SERVER, true));
?>

This will give you tons of info in the error-log, so you'll want to export the result to a text-editor and munch through it there. And/or possibly modify the code to print less info.

A couple of things to look for:

  • Is the action-method called from different places?
  • Is the $_SERVER['UNIQUE_ID'] (or REQUEST_TIME) different?

If the unique-id is different then you've done two requests to the server. If not, try to figure it out from the backtrace.
