我正在尝试使用 php 准备好的语句编辑/更新我的产品页面

[英]I'm trying to edit/update my product page using php prepared statement

问题描述

我在尝试使用 php 准备好的语句编辑/更新包含多个图像的产品页面时遇到问题。 如果我在图像字段中只有一张图像，它将成功更新和取消旧图像的链接，但由于我添加了 4（四）张图像，更新此图像让我很难过。 请有人可以纠正我在这方面的错误吗？

下面是插入页和编辑页

这是我用来将产品插入数据库的代码

<?php
    include 'admin_config.php';

      $mileage      = $_POST['mileage'];
      $isfeatured   = $_POST['isfeatured'];
      $wheel        = $_POST['wheel'];

else块仅连接到image5的最后一个if块。

图像的每个if语句都应该有自己的else来将相应的$newimageX设置为$oldimageX 。

if(isset($_FILES['image']['name'])&&($_FILES['image']['name']!="")){
    $newimage="uploads/".$_FILES['image']['name'];
    unlink($oldimage);
    move_uploaded_file($_FILES['image']['tmp_name'], $newimage);
} else {
    $newimage = $oldimage;
}

if(isset($_FILES['image2']['name'])&&($_FILES['image2']['name']!="")){
    $newimage2="uploads/".$_FILES['image2']['name'];
    unlink($oldimage2);
    move_uploaded_file($_FILES['image2']['tmp_name'], $newimage2);
} else {
    $newimage2 = $oldimage2;
}

if(isset($_FILES['image3']['name'])&&($_FILES['image3']['name']!="")){
    $newimage3="uploads/".$_FILES['image3']['name'];
    unlink($oldimage3);
    move_uploaded_file($_FILES['image']['tmp_name'], $newimage3);
} else {
    $newimage3 = $oldimage3;
}

if(isset($_FILES['image4']['name'])&&($_FILES['image4']['name']!="")){
    $newimage4="uploads/".$_FILES['image4']['name'];
    unlink($oldimage4);
    move_uploaded_file($_FILES['image4']['tmp_name'], $newimage4);
} else {
    $newimage4 = $oldimage4;
}

if(isset($_FILES['image5']['name'])&&($_FILES['image5']['name']!="")){
    $newimage5="uploads/".$_FILES['image5']['name'];
    unlink($oldimage);
    move_uploaded_file($_FILES['image5']['tmp_name'], $newimage5);
} else {
    $newimage5 = $oldimage5;
}
