Simple WordPress plugin debugging

I’d like to present simplest way I know to debug WordPress plugins. It is a method I was using developing plugin to cloak URL‘s described earlier.

Below You can find the most minimalistic example plugin code possible – all it does is log REQUEST_URI to our debug file located at wp-content/plugins/debug. Row by row. Dirty and simple – and the most important – it does not require us to switch our WordPress to debug mode.

Plugin consists of three parts – plugin description header, debugging function and hook to main function which is executed right before page is rendered.

< ?php

/*
Plugin Name: test
Plugin URI:
Description:
Version:
Author:
Author URI:
*/

?>
< ?php

function debug($msg)
{
        $fp = fopen('wp-content/plugins/debug', 'a');
        fwrite($fp, $msg."\n");
        fclose($fp);
}

function main()
{
        debug($_SERVER['REQUEST_URI']);
}

add_action('init', 'main');

?>

Of course the most important part of the code is debug function which stores results we need to verify to our debug file.
