WordPress News, Hacks, Tips, Tutorials, Plugins and Themes
For debugging inside of WordPress there are different approaches and preferences. I like xDebug and in some cases I use FirePHP. Now there is another possibility which I had to test at least once - debugConsole - I like it.
The debugConsole is a tool for debugging and tracing PHP5 applications on productive servers without compromising the live-traffic.
Inside of WordPress are several of JavaScript libraries available, you can use them easily and you don't need an extra Theme or Plugins. Also, this is the recommended approach to enable libraries , so they won't be loaded more than once. Some notes on these two topics can be found in the article Use JavaScript Libraries In And Of WordPress.
But from time to time you need something specific, so I have some code snippets for you in this post now. And I particularly want to show some examples with jQuery. Many Themes and Plugins using jQuery and it is pretty easy to work with jQuery. In principle, these hooks and calls also apply to your own scripts and other libraries.

Again and again the question comes in: What do you use as an environment to develop with WordPress. Some suggestions I would like to give, these are just my preferences, but I would be happy if you tell me your preferences of tools. Maybe there is one or the other useful tool included, I never heard of.

With WordPress 3.0 debugging will be easier, whereas one constants gets eliminated and an already existing constant will do their work.
For developers the following 3 constants are important and should exist in every wp-config.php of a development system. Please use it with precaution on a live system!
Add
define('WP_DEBUG', true);to wp-config.php to enable
the reporting of notices during development.Add
define('WP_DEBUG_DISPLAY', false);to wp-config.php to
disable the display of errors.Add
define('WP_DEBUG_LOG', true);to wp-config.php to log
eerrors to debug.log in the wp-content directory.
Sets PHP error handling and handles WordPress debug mode.
Recommendation for wp-config.php
/** Debugging WP */
define('WP_DEBUG', true); //enable the reporting of notices during development - E_ALL
define('WP_DEBUG_DISPLAY', true); //use the globally configured setting for display_errors and not force errors to be displayed
define('WP_DEBUG_LOG', true); //error logging to wp-content/debug.log
define('SCRIPT_DEBUG', true); //loads the development (non-minified) versions of all scripts and CSS and disables compression and concatenation,
//define('E_DEPRECATED', true); //E_ALL & ~E_DEPRECATED & ~E_STRICT
A small syntax with huge impact. I recommend this to everyone who is developing with WordPress, especially with Xdebug a fantastic help.
There will be a new function in the coming 3.0 version, which will create a shortlink to a post. At default it will be in the header of your frontend.
