http://www.finalwebsites.com/snippets.php?id=7(查看代碼爲類http://pastebin.com/sqbMw4sRPHP類上傳我想利用現有的PHP類上傳文件的文件

而且我在上傳處理文件,以下代碼

$max_size = 1024*100; // the max. size for uploading  
$my_upload = new file_upload; 

// upload directory 
$my_upload->upload_dir = HOME_PATH."users/"; 

// allowed extensions 
$my_upload->extensions = array(".png", ".jpeg", ".jpg", ".gif"); 
$my_upload->max_length_filename = 50; 
$my_upload->rename_file = true; 

$new_name = "testing" . time(); 

if(isset($Submit)) { 
    $my_upload->the_temp_file = $_FILES['upload']['tmp_name']; 
    $my_upload->the_file = $_FILES['upload']['name']; 
    $my_upload->http_error = $_FILES['upload']['error']; 
    $my_upload->the_mime_type = $_FILES['upload']['type']; 

    // because only a checked checkboxes is true 
    $r = $_POST['replace']; 
    $my_upload->replace = (isset($r)) ? $r : "n"; 

    // use this boolean to check for a valid filename 
    $a = $_POST['check']; 
    $my_upload->do_filename_check = (isset($a)) ? $a : "n"; 
    if ($my_upload->upload($new_name)) { 
     // new name is an additional filename information, 
     //use this to rename the uploaded file 
     $full_path = $my_upload->upload_dir.$my_upload->file_copy; 

     // just some information about the uploaded file 
     $info = $my_upload->get_uploaded_file_info($full_path); 
     // ... or do something like insert the filename to the database 
    } 
} 
$error = $my_upload->show_error_string(); 

據筆者瞭解,該文件應該已經上傳的,但它沒有拋出任何錯誤,也沒有被上傳。

我打電話使用給ajaxForm這個文件(jQuery插件http://malsup.com/jquery/form/#file-upload)。

任何人都可以請指出這裏有什麼問題?

您正在發佈的數據,在本課程中正在接收,請在您的ajaxForm()函數中使用alert檢查 – 2012-02-02 08:05:14

我不知道該怎麼做?在開發者的Web控制檯,我可以看到,雖然正在作出的XHR呼叫。 – ptamzz 2012-02-02 08:10:11

這裏是一個新的上傳類 保存下列塊作爲Uploader.php

<?php 

    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:i:s')).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); 
     } 

    } 

?> 

現在使用上傳類上傳文件。 使用下面的代碼。代碼塊是不言自明的。

<?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 
} 


?>
