CakePHP 1.3和Uploadifive/Uploadify - 將上傳文件名更改爲隨機字符串

Question

我在某種程度上在我的CakePHP應用程序中實現了UPLOADIFIVE。一切似乎都很好，包括上傳多個文件並在數據庫中插入正確的信息。

根據下面的代碼，我想上傳並保存每個文件，並帶有一個隨機名，以考慮當前日期或類似的事情。

我怎麼能做到這一點？

在我Photos Controller，我有以下功能：

// This function is called at every file upload. It uploads the file onto the server 
// and save the corresponding image name, etc, to the database table `photos`. 
function upload() { 
    $uploadDir = '/img/uploads/photos/'; 

    if (!empty($_FILES)) { 
     debug($_FILES); 

     $tempFile = $_FILES['Filedata']['tmp_name'][0]; 
     $uploadDir = $_SERVER['DOCUMENT_ROOT'] . $uploadDir; 
     $targetFile = $uploadDir . $_FILES['Filedata']['name'][0]; 

     // Validate the file type 
     $fileTypes = array('jpg', 'jpeg', 'gif', 'png'); // Allowed file extensions 
     $fileParts = pathinfo($_FILES['Filedata']['name'][0]); 

     // Validate the filetype 
     if (in_array($fileParts['extension'], $fileTypes)) { 

      // Save the file 
      move_uploaded_file($tempFile,$targetFile); 

      $_POST['image'] = $_FILES['Filedata']['name'][0];   

      $this->Photo->create(); 
      if ($this->Photo->save($_POST)) { 
       $this->Session->setFlash($targetFile, 'default', array('class' => 'alert_success')); 
       $this->redirect(array('action' => 'index')); 
      } 
     } else { 
      // The file type wasn't allowed 
      //echo 'Invalid file type.'; 
      $this->Session->setFlash(__('The photo could not be saved. Please, try again.', true)); 
     } 
    } 
} 

在我View file - admin_add.ctp我增加了以下功能

$('#file_upload').uploadifive({ 
    'auto' : false, 
    'uploadScript' : '/photos/upload', 
    'buttonText' : 'BROWSE FILES', 
    'method' : 'post', 
    'onAddQueueItem' : function(file) { 
     this.data('uploadifive').settings.formData = { 'photocategory_id' : $('#PhotoPhotocategoryId').val() }; 
    } 
}); 


<input type="file" name="file_upload" id="file_upload" />

function upload() { 
$uploadDir = '/img/uploads/photos/'; 

if (!empty($_FILES)) { 
    debug($_FILES); 

// $tempFile = $_FILES['Filedata']['tmp_name'][0]; 
    $uploadDir = $_SERVER['DOCUMENT_ROOT'] . $uploadDir; 
    $targetFile = $uploadDir . $_FILES['Filedata']['name'][0]; 

    // Validate the file type 
    $fileTypes = array('jpg', 'jpeg', 'gif', 'png'); // Allowed file extensions 
    $fileParts = pathinfo($_FILES['Filedata']['name'][0]); 

    // Validate the filetype 
    if (in_array($fileParts['extension'], $fileTypes)) { 

     // Save the file 

    $tempFile = time()."_".basename($_FILES['Filedata']['name'][0]); 
    $_POST['image'] = $tempFile; 

     move_uploaded_file($tempFile,$targetFile); 



     $this->Photo->create(); 
     if ($this->Photo->save($_POST)) { 
      $this->Session->setFlash($targetFile, 'default', array('class' => 'alert_success')); 
      $this->redirect(array('action' => 'index')); 
     } 
    } else { 
     // The file type wasn't allowed 
     //echo 'Invalid file type.'; 
     $this->Session->setFlash(__('The photo could not be saved. Please, try again.', true)); 
    } 
    } 
    }

Chetanspeed非常感謝這個迅速幫忙。基於他的解決方案，我能夠使其工作。下面是我工作的代碼略有不同Chetanspeed

function upload() { 
    $uploadDir = '/img/uploads/photos/'; 

    if (!empty($_FILES)) { 

     $tempFile = $_FILES['Filedata']['tmp_name'][0]; // Temp file should not be changed since it contains the physical location of the file /tmp/file.jpg 
     $uploadDir = $_SERVER['DOCUMENT_ROOT'] . $uploadDir; 
     $randomString = time(); // Save this random string to a variable 
     $targetFile = $uploadDir . $randomString."_".basename($_FILES['Filedata']['name'][0]); //randomString is added to target... 

     // Validate the file type 
     $fileTypes = array('jpg', 'jpeg', 'gif', 'png'); // Allowed file extensions 
     $fileParts = pathinfo($_FILES['Filedata']['name'][0]); 

     // Validate the filetype 
     if (in_array($fileParts['extension'], $fileTypes)) { 

          //image name posted to database containing the randomString generated from time...thanks Chetanspeed 
      $_POST['image'] = $randomString."_".basename($_FILES['Filedata']['name'][0]); 

      move_uploaded_file($tempFile,$targetFile);  

      $this->Photo->create(); 
      if ($this->Photo->save($_POST)) { 
       $this->Session->setFlash($targetFile, 'default', array('class' => 'alert_success')); 
       $this->redirect(array('action' => 'index')); 
      } 
     } else { 
      // The file type wasn't allowed 
      //echo 'Invalid file type.'; 
      $this->Session->setFlash(__('The photo could not be saved. Please, try again.', true)); 
     } 
    } 
}
