Question

I m using codeigniter and would like to grab some user info with ajax. This is what I have but it s not working

In the view I have a defined variable:

<script type="text/javascript">
    var end_user = "<? echo $user_id; ?>";
</script>
<div id="tabs6"></div>

js file:

function get_experience()
{
$.post(base_url + "index.php/home/get_experience", { user : end_user }, function(data) {
           if (data.status == 'ok')
           {
$("div#tabs6").html(data);
           }
        else
           { //nothing }
           }, "json");
}

            get_experience();

controller:

public function get_experience()
    {
            $this->load->model('experience_model');
            $end_user = $this->input->post('user');

            $one_exp = $this->experience_model->one_exp($end_user);

            if ($one_exp->num_rows() > 0)
            {
                    $one_exp_html = '<ul>';
                    foreach($one_exp->result() as $exp)
                    {
                            $one_exp_html .= '<li>';
                            $one_exp_html .= $exp->experience;
                            $one_exp_html .= '</li>';
                    }
                    $one_exp_html .= '</ul>';
                    $result = array('status' => 'ok', 'content' => $one_exp_html);
                    return json_encode($result);
                    exit();
            }
            else
            {
                    $result = array('status' => 'ok', 'content' => 'nothing here');
                    return json_encode($result);
                    exit();
            }

    }

model:

function one_exp($end_user)
    {
            $query_str = "SELECT experience FROM exp WHERE user_id = ?";
            $query = $this->db->query($query_str, $end_user);
    }

Answer 1

You need to add return $query to your one_exp method.

EDIT

You’re setting user_id in your view, but then using end_user in your javascript function get_experience().

Also, since it’s json you’ll need to change the html fill to

$("div#tabs6").html(data.content);

For more debugging add an alert to your callback (right before if (data.status == 'ok') add alert(data);)
