因此，我想补充以下内容：

function foo_function() {
    $located = locate_template( \'home.php\' );
     if ( !empty( $located ) ) {
          // \'home.php\' found in Theme, do something
     }
}
add_action(\'init\', \'foo_function\');
// remember to change both of the parameters above, first one for where you want the
// action to happen and the second one the name of the function declared

但这取决于你。
