Colonne personnalisée pour changer le statut du message via ajax

Question

J'essaie actuellement d'impliquer une nouvelle colonne personnalisée dans l'écran de gestion des pages qui me permettra de modifier le statut (publié/en attente) des différentes pages via un simple lien à bascule.

D'après ce que j'ai recueilli, je dois utiliser $ post-> post_status, ' status ' d'une manière ou d'une autre, probablement avec jQuery ou quelque chose du genre. Mais je n'arrive pas à comprendre comment je l'associe à l'ajax. Je pensais pouvoir obtenir de l'aide pour examiner le modificateur de statut de publication par défaut dans l'écran de modification de publication, mais je me suis rendu compte que ce n'est pas basé sur l'ajax.

Voici mon essai moche d'essayer jusqu'ici:

function wp_change_page_status_link() {
    $status = get_post_status($ID);
    if($status == 'publish'){
        $status = '<span>On</span>';
        //$post->post_status, 'pending'
    }
    elseif($status == 'pending'){
        $status = '<span>Off</span>';
    }
    return $status;
}

Je serais vraiment reconnaissant si quelqu'un pouvait me diriger dans la bonne direction.
