单击添加到购物车时，如何自动将图像保存在网站内？

Question

如何自动保存这张披萨图片，并将其保存到我的本地文件夹？我可以轻松保存其他信息，但我遇到自动将图像本身保存在本地文件夹中的问题？

我正在从不同 table 获取其他数据，但我无法保存图像本身。我无意使用外键。

backend.php

if (isset($_POST['addcart'])) {
    $con = connection();
    $fetch = singleInfo();
    $name = $fetch['name'];
    $price = $fetch['price'];
    $image = $fetch['image'];


    $new_image = '../images/' . $image;

    $stmt = $con->prepare("INSERT INTO `cart`(`name`, `price`,`image`) VALUES ('$name','$price','$new_image')");

    $stmt->execute();
}

index.php

  <?php

session_start();


require('../backend/clientbackend.php');
$fetch = singleInfo();
$current_price = $fetch['price'];





?>

Answer 1

您可以将图像文件从“../uploads/”复制到“../images/”然后保存。你可以用 copy function

来做到这一点

copy documentations

复制（）示例：

<?php
$image = '../uploads/'.$fetch['image'];
$new_image= '../images/'.$fetch['image'];

if (!copy($image , $new_image)) {
    echo "failed to copy $image ...\n";
}
?>
