Type d'erreur non détecté : count() .

Bonjour

En php8, il faut vérifier que la variable est un array avant de faire un count dessus

Regarde la fonction is_array

Merci de m'apporter ton aide pour résoudre ce problème.

J'ai donc intercalé le script que tu m'as présenté entre les lignes 472 et 479.

Puis modifié la ligne 474 à cause d'une erreur de syntaxe.

Ajouté une accolade à la ligne 512.

Désormais j'obtiens ce message d'erreur que voici:

Je pense que le premier message d'erreur concernait la ligne 552.

Donc j'ai placé ta correction entre les lignes 551 et 558 comme indiqué ci dessous:

Cependant ayant redondance des lignes 555 à 557 avec les lignes 561 à 564, je crains qu'il y ait une erreur de ma part.

Peux tu me le confirmer?

Et si possible m'aider à trouver la solution?

Merci.

Ok.

Merci jordane45. Ca marche.

Vive PHP8 !

Problème résolu.
