是的，这可以通过“template\\u redirect”操作实现

我留下来写代码，为自己找到子类别！

function my_subcat_template() {

    if ( <is sub category>) {
        include (TEMPLATEPATH . \'/category-fun.php\');
        exit;
    }
}

add_action(\'template_redirect\', \'my_subcat_template\');

它所做的是重新定义wordpress处理类别（和子类别）模板的方式

function new_subcategory_hierarchy() {  
    $category = get_queried_object();

$parent_id = $category->category_parent;

$templates = array();

if ( $parent_id == 0 ) {
    // Use default values from get_category_template()
    $templates[] = "category-{$category->slug}.php";
    $templates[] = "category-{$category->term_id}.php";
    $templates[] = \'category.php\';      
} else {
    // Create replacement $templates array
    $parent = get_category( $parent_id );

    // Current first
    $templates[] = "subcategory-{$category->slug}.php";
    $templates[] = "subcategory-{$category->term_id}.php";
    $templates[] = "subcategory.php";

    // Parent second
    $templates[] = "category-{$parent->slug}.php";
    $templates[] = "category-{$parent->term_id}.php";
    $templates[] = \'category.php\';  
}
    return locate_template( $templates );
}



add_filter( \'category_template\', \'new_subcategory_hierarchy\' );

或subcategory.php 一般而言，适用于所有子类别
