Question

I have a function in my controller:

function getAllExpense()
    { $date=$this->frenchToEnglish_date($this->input->post('date'));
      $id_user=$this->session->userdata('id_user');
      $where=array('date'=>$date, 'id_user'=>$id_user);
      $allExpenses=$this->expenses_model->get_all('depenses',$where);
      return json_encode($allExpenses);

    }

In the view, I need to do an ajax_call to getAllExpense, but I need also to retrieve the result returned by getAllExpense in case of success(and I can’t do this). Here is my view

function searchExpense()
    {
      var date= $('#dateSearch').val();
      $.ajax({
                            type:'POST',
                            url : '<?php echo site_url()."/public/expenses/getAllExpense/"; ?>',
                            data :'date='+date,

                            success:function(data)
                            {          $('#searchExpense').toggle();


                            }

                    });     
    }

and finally the form :

<div id="searchExpense" class="toogle_form" style="display:none">
           <label><strong>Vos depenses :</strong></label>
           <?php
              if (isset($allExpenses) && ! empty($allExpenses))
                                            {
                          foreach ($allExpenses as $expense)
                                    {
                                      echo $expense['id_depense'] ;
                                      echo ' ';
                                      echo $expense['commentaire'];
                                      echo '</br>';
                                        }
                              }
                              else
                              {
                                echo 'Vous n\'avez pas eu de depenses pour cette date';
                              }
            ?>
       </div>

This does not show anything on the browser.
I can’t use the method of sending data by loading the view in getAllExpense because I already load it in the function index.
Could anyone help me please?

Answer 1

In your controller function getAllExpense, try echoing your json data with a header rather than using return:

Change this:

return json_encode($allExpenses);

to:

$this->output->set_header('Content-Type: application/json; charset=utf-8');
echo json_encode($allExpenses);
