这是我重复的问题。我已经创建添加和使用jQuery删除更多文件。现在，当我单击添加按钮时会发生什么，它表明我一次又一次地选择另一个文件。我可以像这样上传多个文件。但是问题是，当我单击“提交”按钮插入数据库并将图像移动到文件夹时，它向我显示错误，即

我在您的代码中找到了原因：

$banner_image_tmp = $_FILES['product_image']['tmp_name'];

$banner_image_tmp将返回一个数组。所以会有一个错误

move_uploaded_file() expects parameter 1 to be string, array given

http://php.net/manual/en/features.file-upload.multiple.php。您的代码应为：

if(isset($_POST['submit']))
{
    $file_ary = reArrayFiles($_FILES['product_image']);

    foreach ($file_ary as $file) {
        print 'File Name: ' . $file['name'];
        print 'File Type: ' . $file['type'];
        print 'File Size: ' . $file['size'];
        //Your custom code here

    }
}

function reArrayFiles(&$file_post) {

    $file_ary = array();
    $file_count = count($file_post['name']);
    $file_keys = array_keys($file_post);

    for ($i=0; $i<$file_count; $i++) {
        foreach ($file_keys as $key) {
            $file_ary[$i][$key] = $file_post[$key][$i];
        }
    }

    return $file_ary;
}

如何插入多个图像并将其移入php中的文件夹？
