Basically, Wordpress hasn't run query processing on the URL until after your theme has loaded - so if you run conditionals in functions.php: they will always return false. What you need to do is wrap your conditionals in a function and add that function to the 'wp' loader which runs after the URL query processing (and therefore will receive the correct returns on running the conditionals). So the above code would be: <pre><code>function test_conditionals() { if( is_front_page() || is_single() ) { add_filter(); } } add_action('wp', 'test_conditionals');</code></pre> More here under heading 'The Tricky Part': <a href="http://w-shadow.com/blog/2009/02/22/make-your-plugin-faster-with-conditional-tags/" rel="nofollow">http://w-shadow.com/blog/2009/02/22/make-your-plugin-faster-with-conditional-tags/</a> djm on "Filtering something - but only on specific pages." http://themeshaper.com/forums/topic/filtering-something-but-only-on-specific-pages#post-4939 Sun, 05 Jul 2009 19:33:01 +0000 djm 4939@http://themeshaper.com/forums/ Dupe post, see below. djm on "Filtering something - but only on specific pages." http://themeshaper.com/forums/topic/filtering-something-but-only-on-specific-pages#post-4936 Sun, 05 Jul 2009 19:15:12 +0000 djm 4936@http://themeshaper.com/forums/ Yeh, they're all returning false which is what I don't get. <pre><code>echo "is_single: "; var_dump( is_single() ); echo "is_home: "; var_dump( is_home() ); echo "is_front_page: "; var_dump( is_front_page() );</code></pre> in the child themes functions.php returns false for all no matter what page of the site I am on; yet function_exists on all the method names returns true.. Any ideas what could be going on?

What do you get if you do either var_dump( is_single() );, var_dump( is_home() ); or var_dump( is_front_page() ); djm on "Filtering something - but only on specific pages." http://themeshaper.com/forums/topic/filtering-something-but-only-on-specific-pages#post-4898 Fri, 03 Jul 2009 10:57:12 +0000 djm 4898@http://themeshaper.com/forums/ Hi, First off, thanks to Ian and Chris for their hard work on this framework, having a lot of fun making a theme for a new project of mine - which is nearly finished except for a few lil bits: I would like to filter a function but only on the home indexing page and paginations of such and also on the single page. I have tried the following using Wordpresses' conditionals in functions.php with little effect (the filter function does work if I remove the if statements around it however). if is_home() or is_single() { add_filter('etc', 'etc'); } Any pointers? Cheers.
