Dadurch wird ein Feld mit dem Namen "TERM META TEXT" zu Ihren Kategorien hinzugefügt. Ich habe das Nonce herausgenommen, aber ich denke wirklich, dass es wieder rein gehen sollte. Außerdem ist es einfach besser, etwas Desinfektion gegen keine zu haben. Dieses Beispiel enthält Javascript- und CSS-Hooks, die Sie möglicherweise benötigen oder nicht, aber Sie können schnell sehen, wie alle Teile zusammenpassen.
Genießen!
