Plugin Description

This plugin lists all JavaScripts and Style sheets with a control field that lets you control CSS & JavaScript files to include only on the pages where you actually need them. The text field lets you use WP’s Conditional Tags, or any general PHP code.

NOTE: The script logic you introduce is evaluated directly. Anyone who has permission to manage options will have the right to add any code, including malicious and possibly destructive code. There is an optional filter ‘script_logic_eval_override’ which you can use to bypass the EVAL with your own code if needed. (See Other Notes).

Writing Logic Code

The text in the ‘Logic’ field can be full PHP code and should return ‘true’ when you need the script to load. If there is no ‘return’ in the text, an implicit ‘return’ is added to the start and a ‘;’ is added on the end. (This is just to make single statements like is_home() more convenient.)

The Basics

Make good use of WP’s own conditional tags. You can vary and combine code using:

• ! (NOT) to reverse the logic, eg !is_home() is TRUE when this is NOT the home page.
• || (OR) to combine conditions. X OR Y is TRUE when either X is true or Y is true.
• && (AND) to make conditions more specific. X AND Y is TRUE when both X is true and Y is true.

There are lots of great code examples on the WP forums, and on WP sites across the net. But the WP Codex is also full of good examples to adapt, such as Test if post is in a descendent category.

Examples

• is_home() — just the main blog page
• !is_page('about') — everywhere EXCEPT this specific WP ‘page’
• !is_user_logged_in() — shown when a user is not logged in
• is_category(array(5,9,10,11)) — category page of one of the given category IDs
• is_single() && in_category('baked-goods') — single post that’s in the category with this slug
• strpos($_SERVER['HTTP_REFERER'], "google.com")!=false — script to load when clicked through from a google search
• is_category() && in_array($cat, get_term_children( 5, 'category')) — category page that’s a descendent of category 5
• global $post; return (in_array(77,get_post_ancestors($post))); — WP page that is a child of page 77
• global $post; return (is_page('home') || ($post->post_parent=="13")); — home page OR the page that’s a child of page 13

Note the extra ‘;’ on the end where there is an explicit ‘return’.

The ‘script_logic_eval_override’ filter

Before the Script Logic code is evaluated for each script, the text of the Script Logic code is passed through this filter. If the filter returns a BOOLEAN result, this is used instead to determine if the script should load. Return TRUE to load.
