Comment faire une requête avec plusieurs tableaux en PHP

J'essaie de créer un formulaire dans lequel un utilisateur peut rechercher une base de données en utilisant plusieurs filtres. J'ai deux questions: Comment puis-je interroger la base de données avec plusieurs tableaux que chaque filtre sera stocké dans une variable en tant que tableau sur la page de résultats. La seconde est: Comment puis-je m'assurer que si l'utilisateur laisse un filtre vide, le filtre ne le fait pas dans la requête? De plus, il n'est pas nécessaire que l'utilisateur entre quelque chose dans les deux premières entrées de texte. Merci.Comment faire une requête avec plusieurs tableaux en PHP

$ _POST ['plantType'] et toutes les autres entrées de $ _POST sont des tableaux, cela ne fonctionnera pas. –

Permet de spécifier rstone14 car s'il s'agit d'un tableau, il/elle n'a jamais utilisé Like dans la requête. Je suis sûr à 100% que $ _POST ['plantType'] n'est pas un tableau. –

Non, c'est un tableau, 'cos si le nom dans un formulaire ressemble à ceci - plantType [], cela signifie qu'il a plusieurs valeurs, ceci est un tableau. Et dans ce cas un fragment de $ _POST ressemblera à ceci: 'Array ([0] => Perennial [1] => Tree)' –
