Question

我正在编写一个相当简单的文件服务器，并且在上传单个文件，将其移动到服务器上的文件夹并在数据库中保存信息方面做得很好。现在，当我尝试修改它以接受来自单个输入字段的多个文件时，我无法让它在第一次测试错误之后继续进行。

这是我的index.php：

    <body>
       <img src="style/images/sitename.gif" alt="sitename" align="absmiddle" class="displayed" />
        <div id="sidediv">
            <ul>
                <li>Multiple files uploaded at once will return a link to a zip archive of those files.
            </ul> 
        </div><!--close the sidediv-->
        <div id="container">        
            <div id="content">                
                    <!--form starts here-->
                    <form action="upload.php" id="group" method="post" enctype="multipart/form-data" target="upload_target" onsubmit="startUpload();" >
                         <p id="f1_upload_process">Loading...<br/><img src="loader.gif" /><br/></p>
                         <p id="f1_upload_form" align="center"><br/>
                             <label>File:  
                                  <input name="myfile[]" type="file" size="30" multiple="multiple" />
                             </label>
                             <label>
                                 <input type="submit" name="submitBtn" class="sbtn" value="Upload" multiple="multiple" />
                             </label>
                         </p>

                         <iframe id="upload_target" name="upload_target" src="#" style="width:0;height:0;border:0px solid #fff;"></iframe>
                    </form>
                    <!--form ends here-->
            </div>
             <!--<div id="footer"><a href="" target="_blank">sitename</a></div>-->
        </div>
        <div id="link"></div>            
</body>

我的upload.php在这里：

    <?php


    //database
    $username="";
    $password="";
    $database="";
    mysql_connect(localhost,$username,$password);
    @mysql_select_db($database) or die( "Unable to select database");

    $message = array();
    $result = array();
    $fileName = array();
    $ext = array();
    $tmpName = array();
    $path = array();
    $target_path = array();

    $count = count($_FILES['myfile']['name']);
    for($i=0;$i<$count;$i++)
    {   
        //file info
        $fileName[$count] = $_FILES['myfile']['name'][$count]; // Get the name of the file (including file extension).
        $ext[$count] = pathinfo($fileName[$count], PATHINFO_EXTENSION); // Get the extension from the filename.
        $tmpName[$count]  = $_FILES['myfile']['tmp_name'][$count];
        $fileSize[$count] = $_FILES['myfile']['size'][$count];
        $fileType[$count] = $_FILES['myfile']['type'][$count];  

        //file info
/*      $fileName = $myfile['name']; // Get the name of the file (including file extension).
        $ext = pathinfo($fileName, PATHINFO_EXTENSION); // Get the extension from the filename.
        $tmpName  = $myfile['tmp_name'];
        $fileSize = $myfile['size'];
        $fileType = $myfile['type'];*/

       // Edit upload location here
        $destination_path = './files/';
        $allowed_filetypes = array('idx','sub','txt','srt');
        $max_filesize = 5242880; //bytes

        $prefix = substr(md5(time()),0,7); //new name of the file
        $target_path[$count] = $destination_path . $prefix .".".$ext[$count];

        // Check if the filetype is allowed, if not DIE and inform the user.
        if(!in_array($ext[$count],$allowed_filetypes)){
            $result[$count] = 2;
            $message[$count] = "The file you attempted to upload is not allowed.".$fileName[$count];}

       // Now check the filesize, if it is too large then DIE and inform the user.
        else if(filesize($_FILES['myfile']['tmp_name'][$count]) > $max_filesize){
            $result[$count] = 3;
            $message[$count] = "The file you attempted to upload is too large.";}

        else if(!file_exists($destination_path)){
            $result[$count] = 4;
            $message[$count] = "The upload path does not exist";}

       // Check if we can upload to the specified path, if not DIE and inform the user.
        else if(!is_writable($destination_path)){
            $result[$count] = 5;
            $message[$count] = "You cannot upload to the specified directory, please CHMOD it to 777.";}

        else 
        {       
            @move_uploaded_file($tmpName[$count], $target_path[$count]);

            $file_info = pathinfo($fileName[$count]);
            $sql = "INSERT INTO Files SET 
                        uploader_ip = '".$_SERVER['REMOTE_ADDR']."',
                        File_Name = '".$fileName[$count]."',
                        File_Type = '".$fileType[$count]."',
                        File_Size = '".$fileSize[$count]."',
                        File_Hash = '".$prefix.".".$ext[$count]."',
                        File_Extension = '".$file_info['extension']."'";

            $sqlresult = mysql_query($sql);    
            // If the query was successful, give success message
            if(!$sqlresult){
                $result[$count] = 6;
                $message[$count] = "Could not add this file.";//not actually displayed
                 exit;
            }
            else{
                $message[$count] =  "New file successfully added.";//not actually displayed
                $result[$count] = 1;
                $path[$count] = 'Your file upload was successful, view the file <a href="' . $target_path[$count] . '" title="Your File">here</a>';
            }

        }//closes last else (all the writing to the db)
    }
    sleep(1);
?>

<script language="javascript" type="text/javascript">window.top.window.stopUpload(
<?php echo json_encode($result[$count]); ?>,
<?php echo json_encode($message[$count]); ?>,
<?php echo json_encode($path[$count]); ?>,
<?php echo json_encode($count); ?>,
<?php echo json_encode($fileName[$count]); ?>,
<?php echo json_encode($ext[$count]); ?>);
</script>

每当我收到错误“你上传的文件是不允许的”时，它应该通过该测试。非常感谢任何帮助。

我认为您在$count循环内的数组中使用for的任何地方，都需要使用$i代替$count。

$count始终相同（并且超出了数组的范围）。

试一试，看看你是否还有运气。
