If you are developing a plugin on WordPress, you will need to debug your code as you go.
To enable debugging, go to your wp-config.php file.
Find the line…
Replace the line above with the following…
// Turns WordPress debugging on define('WP_DEBUG', true); // Tells WordPress to log everything to the /wp-content/debug.log file define('WP_DEBUG_LOG', true); // Doesn't force the PHP 'display_errors' variable to be on define('WP_DEBUG_DISPLAY', false); // Hides errors from being displayed on-screen @ini_set('display_errors', 0);
Now you all warnings and errors will show up in the /wp-content/debug.log file, including WordPress warnings of deprecated functions.
You can write directly to this log from your plugin using the
//output some debug string error_log( 'this works yo' ); //output some array/object error_log( print_r( $some_obj_or_array, 1 ) );
Kudos to this post. It has some good plugin development tips, including how to enable debugging on WordPress.

First and foremost I apologise as this is completely unrelated to your blog. I’m just trying to get a response by someone at polldaddy/automattic regarding a support ticket request.
As a desperate attempt to make contact with polldaddy I’m going to go ahead and post my question here and maybe it’ll get through.
I want to purchase a polldaddy subscription but I’d like to know if I can:
– set ‘today’ as the default period on the top rated widget.
– remove the word/title ‘posts’ from the top rated widget when posts is selected.
Hi David, the widget will not let you do this as it is. You are however free to download the plugin and add new settings to the widget to allow it to behave in this manner if you like.
If you create a patch, I can review and apply it too.
