Hello Experts,

I am new in Zend Framework, and this code is use for downloading contents. This code is working in localhost but when i tried to execute in linux server it shows error file not found.

public function downloadAnnouncementsAction() { $file= $this->_getParam('file'); $file = str_replace("%2F","/",$this->_getParam('file'));

    // Allow direct file download (hotlinking)?
    // Empty - allow hotlinking
    // If set to nonempty value (Example: example.com) will only allow downloads when referrer contains this text
    define('ALLOWED_REFERRER', '');

    // Download folder, i.e. folder where you keep all files for download.
    // MUST end with slash (i.e. "/" )
    define('BASE_DIR','file_upload');

    // log downloads?  true/false
    define('LOG_DOWNLOADS',true);

    // log file name
    define('LOG_FILE','downloads.log');

    // Allowed extensions list in format 'extension' => 'mime type'
    // If myme type is set to empty string then script will try to detect mime type
    // itself, which would only work if you have Mimetype or Fileinfo extensions
    // installed on server.
    $allowed_ext = array (        
      // audio
      'mp3' => 'audio/mpeg',
      'wav' => 'audio/x-wav',

      // video
      'mpeg' => 'video/mpeg',
      'mpg' => 'video/mpeg',
      'mpe' => 'video/mpeg',
      'mov' => 'video/quicktime',
