Question

我尝试在我的数据库中编辑图像但是我有一条错误消息：注意：未定义的索引：id

$id = $_GET['id'];

我能够添加图像，但我想知道如何更新图像???

<?php

// Connexion à la base de donnée

include('config_bd.php');



// Vérifications des inputs

if(isset($_POST['upload'])){
    move_uploaded_file($_FILES["image"]["tmp_name"],"images/" .basename($_FILES['image']['name']));

    $nom = htmlspecialchars($_POST['nom']);
    $image = htmlspecialchars($_FILES['image']['name']);



    if(empty($nom) || empty($image)){

        if(empty($nom)) {
            echo "<font color='red'>Le champ nom est vide.</font><br/>";
        }

        if(empty($image)) {
            echo "<font color='red'>Le champ image est vide.</font><br/>";
        }

    }else{
        $update = mysqli_query($mysqli, "UPDATE clubs SET nom='$nom',image='$image'WHERE id='$id'");


        echo "<font color='green'>L'entrée a été enregistré!.";
        echo "<br/><a href='view.php'>Consulter</a>";

           }

    }


$id = $_GET['id'];

$select = mysqli_query($mysqli, "SELECT * FROM clubs WHERE id='$id' ");

while($res = mysqli_fetch_array($select)){

    echo "<div id='img_div'>";
    echo "<p>" .$res['nom']."</p>";
    echo "<img src='images/" .$res['image']."'>";
    echo "</div>";
}

?>
