I'm working with WordPress within my project. and I'm using the Netbeans 7.3.1
WordPress has a ton of includes... and the current file I'm working on ( functions.php) cannot know which other files are involved. So, when I type in say $is_IE ( which is a global) or wp_register_nav which is a wordpress function), because they are not defined within the context of the current functions.php, it cannot give me intelisense support.
In this case, what do we do?
Is there a way in NetBeans which allows me to point to a few specific PHP files in my project so that NetBeans would know about the functions and constants defined in those files and hence, it can extend its intellisense support? - just like it does to native PHP functions, even those those functions are not within the current file.
Is it possible?
You can use WordPress native functions and objects in external files on the same webserver by requiring wp_load.php in your header. Just add this at the top:
require_once('relative/path/to/wp-load.php');
Edit: Just realized I read your question completely wrong. This link details how to add intellisense support for your Wordpress project. There is also a WordPress plugin for Netbeans that may do what you want.
I also know there is a plugin for Sublime Text for WordPress snippets and autocompletions - you can find it here on Github.
