Ist es möglich, Add_Filter aus einem Theme zu verwenden, um die Funktion eines Plugins zu ändern?

Kann mit add_filter () eine Plugin-Funktion abgefangen werden?

Ich habe keinen Erfolg, also denke ich, dass ich das falsch mache.

Das Plugin heißt "All in One SEO" und die Funktion, die ich abfangen möchte, befindet sich in der Klasse All_in_One_SEO_Pack und heißt get_original_title ().

Hier ist der Code, den ich abfangen möchte ... speziell, wenn die Methode is_404 () aufgerufen wird ...

class All_in_One_SEO_Pack {

function rewrite_title($header) {
    global $aioseop_options;
    global $wp_query;
    if (!$wp_query) {
        $header .= "<!-- no wp_query found! -->\n";
        return $header; 
    }

    $post = $wp_query->get_queried_object();

    // the_search_query() is not suitable, it cannot just return
    global $s;

    global $STagging;

    if (is_home() && !$this->is_static_posts_page()) {
        $title = $this->internationalize($aioseop_options['aiosp_home_title']);
        if (empty($title)) {
            $title = $this->internationalize(get_option('blogname'));
        }
        $title = $this->paged_title($title);
        $header = $this->replace_title($header, $title);
    } else if (is_attachment()) { 
                        $title = get_the_title($post->post_parent).' '.$post->post_title.' – '.get_option('blogname');
                        $header = $this->replace_title($header,$title);
    } else if (is_single()) {

Es ist so, aber du machst das falsch. Ich kenne dieses Plugin nicht, aber es hängt wahrscheinlich am wp_title-Hook. Sie sollten in der Lage sein, a) remove_filter () aus Ihrem Theme aufzurufen, um die Titelmanipulation des Plugins zu deaktivieren, und/oder b) das vom Plugin zurückgegebene Ergebnis zu überschreiben, indem Sie in denselben Hook einstecken (stellen Sie nur sicher, dass Ihre "Priorität" "höher ist ", dh Ihre Funktion wird später aufgerufen).

Der Filter fängt die Funktion nicht ab, sondern schließt lediglich vorhandene Haken an. Bei dieser Methode können keine Hooks verwendet werden.
