Script Logic Plugin

Introduction

Script Logic is a WordPress plugin that lets you control on which pages scripts and style sheets load using WP’s conditional tags.

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).

Installation

1. Upload plugin to the `/wp-content/plugins/` directory
2. Activate the plugin through the ‘Plugins’ menu in WordPress
3. Configure the plugin at `Settings -> Script Logic`
4. That’s it.

Configuration

You created a page Contact Us (slug = contact-us) and want to include Contact Form 7 scripts only on this page. Find the Contact Form 7 scripts on plugin’s configuration page (they have handle = contact-form-7) and put `is_page(‘contact-us’)` in logic field
