带有多个文件上传的 ajaxForm 提交

Question

过去几天我一直在想如何使用 ajaxForm 插件上传多个文件，但没有成功。尽管我已经找到了一些总体上的示例，但它们要么没有太大帮助，要么显示的是单个文件上传，我设法使其能够正常工作，但不能处理多个文件。

这是html代码

<div id="upload-wrapper">
 <div align="center">
 <form action="driverLoads/fetchDrivers/personnelUploads/processupload.php" method="post" enctype="multipart/form-data" id="uploadForm">
   <input name="FileInput[]" id="FileInput" type="file" multiple/>
   <input type="submit"  id="submit-btn" value="Upload" />
   <img src="driverLoads/fetchDrivers/personnelUploads/images/ajax-loader.gif" id="loading-img" style="display:none;" alt="Please Wait"/>
 </form>
 <div id="progressbox" ><div id="progressbar"></div ><div id="statustxt">0%</div></div>
 <div id="output"></div>

和javascript代码：

$(document).ready(function() { 
 $('#submit-btn').click(function(e) { 
        e.preventDefault();
        $('#uploadForm').ajaxForm({
            target:   '#output',   // target element(s) to be updated with server response 
            beforeSubmit:  beforeSubmit,  // before submission callback function 
            success:       afterSuccess,  // after submission callback
            uploadProgress: OnProgress, //check on the upload progress
            resetForm: true,        // reset the form if upload is success 
            data:{driverid:driverid} //send the driverid as well
        }).submit();             
    });

和php代码：

if(isset($_FILES["FileInput"])){
   $UploadDirectory =  $base_url . '/subSystems/drivers/driverLoads/fetchDrivers/personnelUploads/';

for($i = 0; $i < count($_FILES["FileInput"]['name']);$i++){
//check if this is an ajax request
   if (!isset($_SERVER['HTTP_X_REQUESTED_WITH'])){
       die();
    }


//Is file size is less than allowed size.
    if($_FILES["FileInput"]["size"][$i] > 5242880) {
    die("File size is too big!");
  }

//allowed file type Server side check
switch(strtolower($_FILES['FileInput']['type'][$i]))
    {
        //allowed file types

        //disabled till further notice
        case 'image/png': 
        case 'image/gif': 
        case 'image/jpeg': 
        case 'image/pjpeg':
        case 'text/plain':
        case 'text/html': //html file

        case 'application/x-zip-compressed':
        case 'application/pdf':
        case 'application/msword':
        case 'application/vnd.ms-excel':
        case 'video/mp4':
            break;
        default:
            die('Unsupported File!'); //output error
}

     if(move_uploaded_file($_FILES['FileInput']['tmp_name'][$i], $UploadDirectory.$_FILES['FileInput']['name'][$i] )){
        die('Success! File Uploaded.');
    }else{
       die('Error uploading File!');
    }

  }

 }else{
     $error = codeToMessage($_FILES["FileInput"]["error"][$i]);
    die('Something wrong with upload! Is "upload_max_filesize" set correctly?' . $error);
 }

我认为这是要理解的问题的所有相关代码。当我上传一个文件时，代码再次正常工作。请注意，如果我上传代码也能正常工作，假设是为了争论 3 个文件，但如果只上传第一个 one.If 任何对此有更多经验的人请帮忙，因为我似乎无法发现错误.

提前谢谢你。

在您的 php 代码行中：

if(move_uploaded_file($_FILES['FileInput']['tmp_name'][$i], $UploadDirectory.$_FILES['FileInput']['name'][$i] )){
        die('Success! File Uploaded.');

然后尝试删除行：

die('Success! File Uploaded.');

（或注释掉！）

有效吗？
