comment créer des actions en bloc personnalisées pour un WP_List_Table (classe principale)
J'utilise la classe WP_List_Table et j'ai ajouté les liens pour les actions comme ceci:
function get_bulk_actions() {
$actions = array();
$actions['approv'] ='<a href="#">'.__( 'Approve' ).'</a>';
$actions['reject'] = '<a href="#">'.__( 'Reject' ).'</a>';
$actions['delete'] = '<a href="#">'.__( 'Delete' ).'</a>';
$actions['view'] = '<a href="#">'.__( 'View' ).'</a>';
return $actions;
}
Puis je les affiche dans la fonction display_row() comme ceci:
$actions = $this->get_bulk_actions();
echo $this->row_actions( $actions );
Maintenant, je me demande comment ajouter des actions personnalisées à ces liens que j'ai créés. Y a-t-il un moyen d'envoyer des variables à une page? Pour gérer la base de données de ces liens et repeupler le WP_List_Table créé avant l’action.

Voici le code complet de la classe WP_List_Table:
