首先将此代码粘贴到主题函数中。php

function post_is_in_descendant_category( $cats, $_post = null ){
    foreach ( (array) $cats as $cat ) {
        // get_term_children() accepts integer ID only
        $descendants = get_term_children( (int) $cat, \'category\');
        if ( $descendants && in_category( $descendants, $_post ) )
            return true;
    }
    return false;
}

<?php if (post_is_in_descendant_category(33)){
 include (TEMPLATEPATH . \'/category-events.php\'); 
 exit;
} ?>

它所做的是检查当前类别是否是事件的子类别，如果是，则使用正确的主题文件。
