Widget Logic lets you add 'conditional tags' logic from the usual widget admin interface. It also adds a 'widget_content' filter.

== Description ==
This plugin gives every widget (even widgets lacking controls) an extra control called "Widgets logic".

This text field allows you to specify any wp conditional tags logic to set when the widget appears. Use any standard [Conditional Tags](http://codex.wordpress.org/Conditional_Tags) and even combine them.

== Installation ==

1. Upload `widget-logic.php` to the `/wp-content/plugins/` directory
2. Activate the plugin through the 'Plugins' menu in WordPress
3. That's it. All the configuring is in the usual widget admin interface.

== Frequently Asked Questions ==

= I get no sidebar at all when the plugin is active =

The logic text on one of your widgets may be invalid PHP.

= The 'Widget Logic' field is missing or appears elsewhere =

The plugin uses a tiny bit of javascript to get the field into position on the admin page. As the widget admin uses JS, I feel this is no imposition. However it might mean that your browser dislikes the DOM tricks that the JS code adopts.

I've tested it looks OK on Safari, Firefox and even PC IE6. But let me know what browser you are using and I'll see what I can do.

== Writing Logic Code ==

The text you write in the 'Widget logic' field can currently be full PHP code so long as it returns 'true' when you need the widget to appear - note that you need terminating ';'s.

If there is no 'return' in the text, there is an implicit 'return ' added on the start and a ';' on the end.

Examples:

*	is\_home()
*	is\_category(5)
*	is\_home() || is\_category(5)
*	x=(1==1)?true:false; return ( !is_home && x);

Note the use of ';' where there is an explicit 'return'.
