Creating a new Article

Don't copy via Firefox the contents of an old post; this results in a broken layout. The best way is to edit the old post you want to copy, and copy its HTML code directly.

Although WordPress is great, the plugin development framework is totally broken. It is possible to do whatever you need to do, but the code is 100% ugly and there is no real way of getting your stuff done in a beautiful way. This is just spaghetti PHP code as its worst, a tons of stuff hacked together without any general visions.

If you use register_setting to update some plugin options on the back office, be very careful. All options get updated all the time even if you did not specify a form field for them, and validation is basically nowhere (the sanitize_callback thing is a joke: there's no documentation about it, so no way of knowing how it works).

Use update_option if you want the option updated regardless of the existence of a previous value; use add_option if you only want to change the option if it does not exist before.
