Partager un code de navigation du fil d'Ariane WordPress

Ce qui suit est un code de navigation du fil d'Ariane WordPress partagé par la colonne du didacticiel WordPress. J'espère qu'il sera utile aux amis qui en ont besoin !

Réimprimez et partagez un morceau de code de navigation du fil d'Ariane WordPress qui prend en charge les types de publication personnalisés et les catégories personnalisées, mais il semble dommage que la hiérarchie des catégories parent-enfant ne puisse pas être affichée sur la page d'archive des catégories.

Ajoutez le code au modèle de fonction de thème actuel function.php :
