How to (correcly) pass variables from a loop (in view) to a Controller - El Forum - 03-17-2011

Hello everyone, im trying to create a page in wich people could post some comments or questions of a certain record from a data base, (similar to facebook). The issue is that I'm trying to pass the id of a particular database record, but I end up passing the higest (last) id of the loop

Here it is:
model:

Code:
function get_tarea()

    {

        $this->db->select('id_tarea');

        $this->db->select('descripcion');

        $this->db->order_by("id_tarea","ASC");

        $query = $this->db->get('sup_tarea');

        return $query->result();

   }

view

Code:
foreach ($tarea as $row):

  echo form_open('support/question_insert');

  echo form_hidden('id_tarea', $row->id_tarea);// here's where I think the problem is

  echo form_textarea(array('name' => 'question', 'id' => 'question', 'value' => 'enter comment here'));

  echo form_submit( 'submit_comment', 'Enviar');

  form_close();

endforeach;

controller (for the insertion)

Code:
function question_insert(){

  $data_question['question'] = $this->input->post('question');

  $data_question['id_tarea'] = $this->input->post('id_tarea');

  $this->db->insert('sup_question', $data_question);

  redirect('support');

 }

The issue is that post('id_tarea') is always the same: the last record from the database.

If anyone wants to see the actual output of this code: http://www.nemoestudio.com/es/support

Thanks in advance for your ideas!

You need an echo on your form_close(). Your browser is treating this as one big form, and where multiple inputs have the same name, the last one POSTed will be used as the value.
