CodeIgniter3 - 存储PDF文件的位置？

Question

I ma using CodeIgniter3 to build projects. However I am not sure where is the best place to store generated PDF files. I do not want to keep them in MySQL due to its size.

I do not want people to access direct links like: http://mydomain/pdf/file.pdf but I would like to give this kind of access for codeigniter logged users.

What is the best way to do that?

Answer 1

1. Create site/pdf_files/.htaccess file and add this line:

   Deny from all
   

2. Make router config as follows

   /*
    anything in second segment of pdf controller will be routed to
    index method 
   
    serve file like : 
    http://example.com/pdf/myfile.pdf
   */
   $route['pdf/(:any)'] = "pdf/index/$1";
   
   /*
    Note: if you got some more methods in same controller prefer below one
    because, with above one, anything in second segment will be routed to 
    index method  
   
    $route['pdf/display/(:any)'] = "pdf/index/$1";
   
    and serve files like
    http://example.com/pdf/display/myfile.pdf
   */
   

3. and then while serving pdf to user prefer codeigniter file helper like below

   class Pdf extends CI_Controller
   {
   
   function download_file($path, $name)
   {
     // make sure it's a file before doing anything!
     if(is_file($path))
     {
   
       // get the file mime type using the file extension
       $this->load->helper('file');
   
       header('Content-Type: '.get_mime_by_extension($path));  
       header('Content-Disposition: attachment; filename="'.basename($name).'"');  // Add the file name
       header('Content-Transfer-Encoding: binary');
       header('Content-Length: '.filesize($path)); // provide file size
       header('Connection: close');
       readfile($path); 
       die();
     }
   }
   
    public function index($file)
    {
       // here you check whether user logged in or not
   
        $this->download_file('pdf_files/'.$file, $file);
    }
   }
