PHP 上传多张图片

Question

这段代码曾经有效，现在我不明白为什么它无法上传，我没有收到错误，我也没有收到任何回声或 var_dumps，它是就像按钮只刷新页面一样。（只是为了澄清，有更多的代码做了很多事情，但这是我的问题的原因，因为我用下面的代码将它隔离到另一个项目中，这给了我相同的结果）。

它要做的就是创建一个由 "ItemName" 命名的文件夹，然后它应该将图像移动到那个新命名的文件夹中。

提前谢谢你，这个问题已经困扰我好几天了...

我已经创建了简单的代码来上传多张图片。改成你的。

<?php
if(isset($_FILES['files'])){
$errors= array();
foreach($_FILES['files']['tmp_name'] as $key => $tmp_name ){
    $file_name = $key.$_FILES['files']['name'][$key];
    $file_size =$_FILES['files']['size'][$key];
    $file_tmp =$_FILES['files']['tmp_name'][$key];
    $file_type=$_FILES['files']['type'][$key];  
    if($file_size > 2097152){
        $errors[]='File size must be less than 2 MB';
    }       
    $query="INSERT into upload_data (`USER_ID`,`FILE_NAME`,`FILE_SIZE`,`FILE_TYPE`) VALUES('$user_id','$file_name','$file_size','$file_type'); ";
    $desired_dir="user_data";
    if(empty($errors)==true){
        if(is_dir($desired_dir)==false){
            mkdir("$desired_dir", 0700);        // Create directory if it does not exist
        }
        if(is_dir("$desired_dir/".$file_name)==false){
            move_uploaded_file($file_tmp,"$desired_dir/".$file_name);
        }else{                                  // rename the file if another one exist
            $new_dir="$desired_dir/".$file_name.time();
             rename($file_tmp,$new_dir) ;               
        }
     mysql_query($query);           
    }else{
            print_r($errors);
    }
}
if(empty($error)){
    echo "Success";
}

} ?>

<form action="" method="POST" enctype="multipart/form-data">
<input type="file" name="files[]" multiple/>
<input type="submit"/>
