Wordpress FirePHP plugin

9 Comments 24th FEB 2009 | Posted by Ivan Weiler in Wordpress

While tracing some code in Wordpress i got tired of var_dumps, so i quickly coded FirePHP plugin. All it does is include FirePHP and forces Wordpress to load it before other plugins, so that you can use it in plugin development.

wp_firephp_v.0.2.rar
wp_firephp_v.0.1.rar

It’s tested on WP 2.7 and someone might find it useful! I got few more ideas to implement to make it useful for theme debugging, but that’s another version

Thanks for implementing a plugin for wordpress.

I have added a link to this post to the FirePHP Wiki: http://www.firephp.org/Wiki/Libraries/Wordpress

I just cannot get this to work. Installs fine on WP 2.7.1 running php 5. I’ve got both Firebug and Firephp plugins installed. I typed in fb(‘hello’); in my functions.php for just for a test but nothing shows up on the console. Any ideas?

I just added some small changes. Now theme debugging should work.

@jding: It should solve your functions.php problem.

Hello all,

I am having troubles to get the plugin to work. That’s what i did:

1) Unzip the plugin into the /plugins directory.
2) Insert this code in my index.php:

10, ‘j’=>20);

$firephp->log($var, ‘Iterators’);

?>

But then I get the following error:

Fatal error: Uncaught exception ‘Exception’ with message ‘Headers already sent in /var/www/wordpress2/wp-content/themes/extended/header.php on line 2. Cannot send log data to FirePHP. You must have Output Buffering enabled via ob_start() or output_buffering ini directive.’ in /var/www/wordpress2/FirePHPCore/FirePHP.class.php:949 Stack trace: #0 /var/www/wordpress2/FirePHPCore/FirePHP.class.php(624): FirePHP->newException(‘Headers already…’) #1 /var/www/wordpress2/FirePHPCore/FirePHP.class.php(510): FirePHP->fb(Array, ‘Iterators’, ‘LOG’) #2 /var/www/wordpress2/wp-content/themes/extended/index.php(11): FirePHP->log(Array, ‘Iterators’) #3 /var/www/wordpress2/wp-includes/template-loader.php(27): include(‘/var/www/wordpr…’) #4 /var/www/wordpress2/wp-blog-header.php(16): require_once(‘/var/www/wordpr…’) #5 /var/www/wordpress2/index.php(17): require(‘/var/www/wordpr…’) #6 {main} thrown in /var/www/wordpress2/FirePHPCore/FirePHP.class.php on line 949

Any help would be really appreciated as I usually develop for wordpress.

Thanks in advance.

@Javier:
This plugin starts output caching(ob_start()) at init hook.

I’m not sure if this error has anything to do with my plugin since i see that your firephp class is at /var/www/wordpress2/FirePHPCore/FirePHP.class.php. Or did you change include path?

If you’re using FirePHP that you included yourself, just try to add ob_start() before any wp output.

Or just remove any instance of FirePHP if you have it and install v.0.2 of my plugin.

Sorry, I paste the php code again:

$firephp = FirePHP::getInstance(true);

$var = array(‘i’=>10, ‘j’=>20);

$firephp->log($var, ‘Iterators’);

Thanks in advance!!
