If you want to use the override conditionally then you will need the condition to precede the child override function like so:</p> <pre><code>if ( is_category('drawing') ) { function childtheme_override_category_loop() { // do something } }</code></pre> <p>Depending on which parent function you are overriding and the point of that parent function is executed, you may or may not need to load a global variable such as <code>global $post</code>. So generally it may be best to wrap the whole condition in a function and call the global variable that you might need.</p> <pre><code>function my_conditional_*() { global $post; if ( is_*() ) ) { function childtheme_override_*() { // do something } } }</code></pre> ridgely on "Conditional childtheme_override" http://themeshaper.com/forums/topic/conditional-childtheme_override#post-15408 Mon, 06 Sep 2010 22:45:09 +0000 ridgely 15408@http://themeshaper.com/forums/ <p>(Building from 0.9.7.4 rev709)<br /> If you want a conditional <code>childtheme_override</code>, for example, you want to use the <code>childtheme_override_category_loop</code> only on certain category pages, where does the condition need to occur. I tried inserting the condition within the <code>childtheme_override</code> but that didn't work entirely as intended, i.e. it affected ALL my category pages:<br /> <pre><code>/*Custom Category Loop for certain Categories*/ function childtheme_override_category_loop() { if (is_category('drawing')|| is_category('painting')) { while ( have_posts() ) : the_post() // Start the loop: ?> <div id="post-<?php the_ID() ?>" class="<?php thematic_post_class() ?>"> <?php thematic_postheader(); ?> <?php get_the_image( array( 'custom_key' => array( 'Thumbnail', 'thumbnail' ), 'default_size' => 'thumbnail' ) ); ?> <div class="entry-content"> <?php thematic_content(); ?> </div> <?php thematic_postfooter(); ?> </div> <?php endwhile; // loop done, go back up } }</code></pre>
