多文件上传与循环

Question

目前，我有这个脚本，用户（使用一种形式，他们可以上传多达七个图像）可以上传多张图片到一个文件夹和图像的名字我的数据库中，没有任何成功。请帮忙。

if (isset($_POST['submit'])) { $ref_49 = $_POST['ref_49']; 
    $name = $_POST['name']; 
    $contact = $_POST['contact']; 
    $email = $_POST['email']; 
    $rent_sell = $_POST['rent_sell']; 
    $heading = $_POST['heading']; 
    $price = $_POST['price']; 
    $limitedtextarea = $_POST['limitedtextarea']; 
    $type = $_POST['type']; 
    $where = $_POST['where']; 
    $address = $_POST['address']; 
    $bedroom = $_POST['bedroom']; 
    $bathroom = $_POST['bathroom']; 
    $garages = $_POST['garages']; 
    $carports = $_POST['carports']; 
    $granny_flat = $_POST['granny_flat']; 
    $ref_99 = $_POST['ref_99']; 
    $fulldesc = $_POST['full_desc']; 

    if ($ref_99=="") { 
    $full_ad = "yes"; 
    } else { 
    $full_ad = "no"; 
    } 
    $todays_date = date("Y-m-d"); 
    mkdir("gallery/" . $_POST["name"], 0777); 

for ($i = 0; $i < 7; $i++) 
{ 
    $file_name = $_FILES['uploadFile' . $i]['name']; 
    // strip file_name of slashes 
    $file_name = stripslashes($file_name); 
    $file_name = str_replace("'", "", $file_name); 
    // $copy = copy($_FILES['uploadFile'. $i]['tmp_name'], "gallery/" . $_POST["name"] . "/" . $file_name); 

    if ((($_FILES['uploadFile' . $i]["type"] == "image/gif") 
     || ($_FILES['uploadFile' . $i]["type"] == "image/jpeg") 
     || ($_FILES['uploadFile' . $i]["type"] == "image/pjpeg")) 
     && ($_FILES['uploadFile' . $i]["size"] < 200000000)) 
    { 
     if ($_FILES['uploadFile' . $i]["error"] > 0) 
     { 
      $message = "Return Code: " . $_FILES['uploadFile' . $i]["error"] . "<br />"; 
     } 
     else 
     { 
      $query = "INSERT INTO property (

      $result = mysql_query($query, $connection);

    }

这里可能会出现很多问题。你有没有试图把它分解成碎片？你确定数据库连接吗？你确定php有权写入它试图写入的目录吗？你确定那些目录存在...等等。等

注释掉绝大多数的代码，并开始测试全部由一块一块的部件，或包裹在try/catch语句的东西，看看产生了什么错误。

如果只有当您上传< 7个文件时才会出现问题，那么问题在于您已将硬编码到您的循环中！

循环播放实际上传的文件数量，不是固定的数字。

假设它们都是按顺序命名的（并且从0开始），你可以测试循环中散列FILE值的存在性，并继续摄取，直到它变为空（可能是添加限制器来制作肯定不能一直持续下去）

这样的事情...

[编辑2]修改的条件，包括对文件大小的测试

for($i=0; $_FILES['uploadFile' . $i] && $_FILES['uploadFile' . $i]['size'] > 0 && $i<100 ; $i++){ 
    try{ 
    //do your upload stuff here 
    }catch(e){} 
} 

[编辑] 要修改您的页面以包含动态编号场的R请勿这一点：

检查出这个小提琴：http://jsfiddle.net/RjcHY/2/

点击加号和减号按钮在右侧，看看它是如何工作的。我这样做是为了按照你的php的期望命名文件按钮。

在处理像文件上传共同任务，写一些库来处理这些任务和需要的地方调用必要的功能。如果您创建上传器类文件，则可以简单地调用您创建的用于处理文件上传的方法之一。

在这里，我会给你一个上传类

<?php 

//Save file as Uploader.php 
//File Uploading Class 

class Uploader 
{ 
private $destinationPath; 
private $errorMessage; 
private $extensions; 
private $allowAll; 
private $maxSize; 
private $uploadName; 
private $seqnence; 
public $name='Uploader'; 
public $useTable =false; 

function setDir($path){ 
$this->destinationPath = $path; 
$this->allowAll = false; 
} 

function allowAllFormats(){ 
$this->allowAll = true; 
} 

function setMaxSize($sizeMB){ 
$this->maxSize = $sizeMB * (1024*1024); 
} 

function setExtensions($options){ 
$this->extensions = $options; 
} 

function setSameFileName(){ 
$this->sameFileName = true; 
$this->sameName = true; 
} 
function getExtension($string){ 
$ext = ""; 
try{ 
$parts = explode(".",$string); 
$ext = strtolower($parts[count($parts)-1]); 
}catch(Exception $c){ 
$ext = ""; 
} 
return $ext; 
} 

function setMessage($message){ 
$this->errorMessage = $message; 
} 

function getMessage(){ 
return $this->errorMessage; 
} 

function getUploadName(){ 
return $this->uploadName; 
} 
function setSequence($seq){ 
$this->imageSeq = $seq; 
} 

function getRandom(){ 
return strtotime(date('Y-m-d H:iConfused')).rand(1111,9999).rand(11,99).rand(111,999); 
} 
function sameName($true){ 
$this->sameName = $true; 
} 
function uploadFile($fileBrowse){ 
$result = false; 
$size = $_FILES[$fileBrowse]["size"]; 
$name = $_FILES[$fileBrowse]["name"]; 
$ext = $this->getExtension($name); 
if(!is_dir($this->destinationPath)){ 
$this->setMessage("Destination folder is not a directory "); 
}else if(!is_writable($this->destinationPath)){ 
$this->setMessage("Destination is not writable !"); 
}else if(empty($name)){ 
$this->setMessage("File not selected "); 
}else if($size>$this->maxSize){ 
$this->setMessage("Too large file !"); 
}else if($this->allowAll || (!$this->allowAll && in_array($ext,$this->extensions))){ 

if($this->sameName==false){ 
$this->uploadName = $this->imageSeq."-".substr(md5(rand(1111,9999)),0,8).$this->getRandom().rand(1111,1000).rand(99,9999).".".$ext; 
}else{ 
$this->uploadName= $name; 
} 
if(move_uploaded_file($_FILES[$fileBrowse]["tmp_name"],$this->destinationPath.$this->uploadName)){ 
$result = true; 
}else{ 
$this->setMessage("Upload failed , try later !"); 
} 
}else{ 
$this->setMessage("Invalid file format !"); 
} 
return $result; 
} 

function deleteUploaded(){ 
unlink($this->destinationPath.$this->uploadName); 
} 

} 

?> 

使用Uploader.php

<?php 

$uploader = new Uploader(); 
$uploader->setDir('uploads/images/'); 
$uploader->setExtensions(array('jpg','jpeg','png','gif')); //allowed extensions list// 
$uploader->setMaxSize(.5); //set max file size to be allowed in MB// 

if($uploader->uploadFile('txtFile')){ //txtFile is the filebrowse element name // 
$image = $uploader->getUploadName(); //get uploaded file name, renames on upload// 

}else{//upload failed 
$uploader->getMessage(); //get upload error message 
} 


?> 

处理多个上传，前3张图片上传 重复块如下

<?php 

for($i=1;$i<=3;$i++){ 

    $uploader->setExtensions(array('jpg','jpeg','png','gif')); //allowed extensions list// 
    $uploader->setMaxSize(.5); //set max file size to be allowed in MB// 
    $uploader->setSequence($i); 
    if($uploader->uploadFile('txtFile'.$i)){ //txtFile is the filebrowse element name // 
     $image = $uploader->getUploadName(); //get uploaded file name, renames on upload// 

    }else{//upload failed 
    $uploader->getMessage(); //get upload error message 
    } 

} 

?> 

在上例中，

，文件浏览组件被命名为txtFile1，txtFil e2，txtFile3 希望你能理解我的解释。
