Delete file after uploading to codeigniter

Question

I want to delete a file from the download directory after user download. But he does not leave. I am using Codeigniter download_helper to download a file. Below is my code:

controller

public function download($key,$id)
{
    $link=$this->article->download($key,$id);//get record from database via article model
    if(empty($link))
    {
        show_404(); 
    }
    force_download(DOWNLOADS_PATH.$link->file_name, NULL);//download file
    $this->article_lib->remove_downloaded($link->file_name);//user has downloaded so now delete this
}

Library

public function remove_downloaded($file_name)
{
   if(file_exists(DOWNLOADS_PATH.$file_name))
     {
      unlink(DOWNLOADS_PATH.$file_name);
     }
}

Answer 1

Sorry I didn’t read, but the problem with your code is that it has no closure )

    public function remove_downloaded($file_name)
    {
       if(file_exists($file_name)) // here is the problem
         {
          unlink($file_name);
         }
    }

Also, how power loading works, everything that does not start. I would suggest using an ajax call after the controller.

UPDATE:

But, as you mentioned in your comment, you can delete the file before creating it, as indicated in this Unlink post after forcing a download that does not work Codeignign
