Question

获得一个将产品添加到网上商店的表格。您最多可以上传10张图像，最小为1张图像。即使将文件名完美地插入到MySQL数据库中，文件也不会移动到正确的文件夹中。

我正在使用共享的Web主机PHP 5.2，该文件具有写权限。已经与虚拟主机进行了交谈，这不是权限问题。

<form action="" method="post" enctype="multipart/form-data">
                  <div class="form-group">
                    <label for="img1"><b>Image 1</b></label>
                    <input required type="file" class="form-control" name="img1" placeholder="Image 1 (name of the first image, upload it as instructed)">
                  </div>

表格^

的图像部分

    <?php

    if(isset($_POST['name'])){
        $img1 = $_FILES['img1']['name'];
        $img2 = $_FILES['img2']['name'];
        $img3 = $_FILES['img3']['name'];
        $img4 = $_FILES['img4']['name'];
        $img5 = $_FILES['img5']['name'];
        $img6 = $_FILES['img6']['name'];
        $img7 = $_FILES['img7']['name'];
        $img8 = $_FILES['img8']['name'];
        $img9 = $_FILES['img9']['name'];
        $img10 = $_FILES['img10']['name'];

        move_uploaded_file($_FILES['img1']['tmp_name'],"../assets/img/carousel/");
        move_uploaded_file($_FILES['img2']['tmp_name'],"../assets/img/carousel/$img2");
        move_uploaded_file($_FILES['img3']['tmp_name'],"../assets/img/carousel/$img3");
        move_uploaded_file($_FILES['img4']['tmp_name'],"../assets/img/carousel/$img4");
        move_uploaded_file($_FILES['img5']['tmp_name'],"../assets/img/carousel/$img5");
        move_uploaded_file($_FILES['img6']['tmp_name'],"../assets/img/carousel/$img6");
        move_uploaded_file($_FILES['img7']['tmp_name'],"../assets/img/carousel/$img7");
        move_uploaded_file($_FILES['img8']['tmp_name'],"../assets/img/carousel/$img8");
        move_uploaded_file($_FILES['img9']['tmp_name'],"../assets/img/carousel/$img9");
        move_uploaded_file($_FILES['img10']['tmp_name'],"../assets/img/carousel/$img10");

获取文件名并将其移动到正确文件夹的部分。

文件没有移到旋转木马文件夹，而是根本没有移到任何地方：

Answer 1

这肯定是权限问题或路径问题。目标目录必须存在，并且可由PHP进程写入。对于目标，请使用绝对路径，而不要使用相对路径，如果要使用相对路径，请确保使用dirname（ FILE ）。 '/../ assets'

假设以上所有内容均正确，那么它将对您有用！

Answer 2

所以Cherrysoft所说的是正确的；几乎可以肯定是权限问题，或者没有达到您认为的路径。

尽管如此，我将借此机会帮助您改进代码。您的示例可以简化，以便更轻松地添加10个以上的图像，并且更易于维护。这是您当前代码的更好替代方法：

if(isset($_POST['name'])){
    foreach($_FILES as $key => $file) {
        move_uploaded_file($file['tmp_name'],"../assets/img/carousel/{$file['name']}");
    }
}

这样，您的代码就不会那么重复了。有一些方法可以进一步改善这一点，但是我不想被迷住。

PHP move_uploaded_file（）函数不起作用
