Hello everybody.

Now I’m creating a download manager of the next way:

1: In the model file I made the query selection to my DB.
2: In a controller I get the data from my DB and I organize it trought of a foreach loop seting the data in a table and then show it in a output function.
3: In my app when I look the table in the view, I see the data tabulate and paginate by 10 records. each record has 4 rows. the rows are the name, created by, date and a selected field.
  -When I onclick on the name of the record (LINK) the download start automatically, downloading the correponding file.
  ¡For this there are somy variables that I get but don’t show, which are the route of my file!.

All goes fine, But I’m truncated in what I don’t know how to send the selected route to my controller route.

Actually I have this:

if ($query->num_rows() > 0)
  {
  foreach($query->result_array() as $row)
  {
   $data = array(
   'fechacreacion' => $row['fechacreacion'],
   'descripcion' => $row['descripcion'],
   'codigoagencia' => $row['codigoagencia'],
   'nombreacta' => $row['nombreacta'],
   'rutaarchivo' => $row['rutaarchivo'],
   );
   $content.="
   <tr>
    <td id=''><input name='opcion-res' type='radio' align='center'/></td>
    <td id=''><a href='download'>$data[descripcion]</a></td>
    <td id=''>$data[rutaarchivo]</td>
    <td id=''>$data[fechacreacion]</td>
   </tr>
   ";   
  }
   $this->session->set_userdata('logged_content', $data);  
  }
  $this->output->set_output($content); 

If someone has a better Idea of Howa could to be a download manager, I will thanks that let me know.

How does the ‘download’ Controller works? Does it get the file path from the DB as from an ID, alias or another identifier?

Hello, Thanks my friend..

Basically my Download controller is this.

function index()
 {
  $data = $this->session->userdata('logged_content');
  echo $data['rutaarchivo'];
  /*
  $ruta = $data['rutaarchivo'];
  $this->load->helper('download');
  $data = file_get_contents($_SERVER['DOCUMENT_ROOT'] . "/Online-App/filesFolder/" . $ruta);
  $name = $ruta;
  force_download($name, $data);
  */
 } 

This have the comentary because now I’m trying of just to show the variable, Is for test and when I get Ok I quit the “/*”.
Now I ask me if there a way of pass a variable with the controller. Ergo.

<a href='download/$data'></a> 

Or some like this for may get the value that has a row in the loop. I already tried of use

$this->session->set_userdata($data); 

But get the value of array but not of the loop.

Got it.
So you must do this:

$content.="
   <tr>
    <td id=''><input name='opcion-res' type='radio' align='center'/></td>
    <td id=''><a href='download/$data[rutaarchivo]'>$data[descripcion]</a></td>
    <td id=''>$data[rutaarchivo]</td>
    <td id=''>$data[fechacreacion]</td>
   </tr>
   "; 

Then, in the download controller:

function index($ruta) // $ruta is the first parameter after the slash '/'
 {
  echo $ruta; // Path to the chosen file 
  /*
  $ruta = $data['rutaarchivo'];
  $this->load->helper('download');
  $data = file_get_contents($_SERVER['DOCUMENT_ROOT'] . "/Online-App/filesFolder/" . $ruta);
  $name = $ruta;
  force_download($name, $data);
  */
 } 

* En lugar de “download/$data[rutaarchivo]” use el ID del archivo. Así, el nombre o la ruta permanecen ocultos

Hello.
I see your response and tryied to do it but, when I onclick in the link pass the variable through of URL and obvisuly find not nothing.

I was thinking if there the possibility of create some like in javascript “onselect”. I just need pass the variable inside the loop.

In javascript wil be like

var a = document.getElementById('some');
if(a.onclick)
{
   alert(a.value);
} 

If do you can response in spanish there not problem, I speak spanish perfectly. Thanks
