Question

我尝试在我的数据库中更新或插入订单，但我有一个问题，因为我有2个ID第一个（id_commande - 自动增量）的订单，第二个是与其他表相关的成员。

我找不到如何调用id_commande。

<?php
    session_start();
    // on teste si le visiteur a soumis le formulaire

    if (isset($_POST['commande']) && $_POST['commande'] == 'commande') {
        commander('homme', 'id_commande');
    }
    else if (isset($_POST['commande_femme']) && $_POST['commande_femme'] == 'commande_femme') {
        commander('femme', 'id_commande');
    }


    function commander($commande,$id_commande){

            // $id = $_SESSION['id'];
            // Connection au serveur
              $dns = 'mysql:host=localhost;dbname=carole';
              $utilisateur = 'acces_site';
              $motDePasse = 'password';
              $connection = new PDO( $dns, $utilisateur, $motDePasse );


            $req = $connection->prepare('SELECT * FROM commande WHERE id_commande = ?');
            $req->execute(array($id_commande));
            $stmt = $req->rowCount();

            if ($stmt == 1){
                // SI IL EXISTE 1 SINON 0 
                $sql = "UPDATE commande SET commande = :commande, quantite_commande = :quantite_commande WHERE id = :id";
                $stmt = $connection->prepare($sql);
                $stmt->bindParam(':commande', $commande);
                $stmt->bindParam(':quantite_commande', 'quantite_'.$commande);
                $stmt->execute(array(':commande' => $_POST[$commande], ':quantite_commande' => $_POST['quantite_'.$commande], ':id' => $id ));

            }
            else {

                $sql = 'INSERT INTO commande (id,commande,quantite_commande) VALUES (:id, :commande, :quantite_commande)';

                $stmt = $connection->prepare($sql);
                $stmt->bindParam(':commande', $commande);

                $stmt->execute(array(':id' => $id, ':commande' => $_POST[$commande], ':quantite_commande' => $_POST['quantite_'.$commande]));
            }


}

我需要你的帮助！ THX

Answer 1

也许你需要使用PDO::lastInsertId吗？

Answer 2

在这一行：

$stmt->execute(array(':commande' => $_POST[$commande], ':quantite_commande' => $_POST['quantite_'.$commande], ':id' => $id ));

如果你之前没有定义它，你是如何使用$ id的？！？！

php动态变量id
