Question

I ve been trying to post something using ajax but I m getting a Failed to load resource: the server responded with a status of 500 (Internal Server Error). All other forms on the site using ajax work this is the only one that’s giving the error. Not sure what is going on … maybe someone will notice something I m not.

jQuery
(user_id is already defined in the view. alert returns everything I need to pass to the controller)

$('.one_add').submit(function(e) {
            e.preventDefault();

            var formID = $(this).attr('id');
            var formIDSplit = formID.split('-');
            var oneID = formIDSplit[1];

            var url = $('.one-link-'+oneID).val();
            var desc = $('.one-link-desc-'+oneID).val();

            $.post(base_url + "index.php/home/one_link", { user_id : user_id, one_id : oneID, desc : desc, url : url  }, function(data)
            {
            }, "json");

//              alert(user_id+'-'+oneID+'-'+desc+'-'+url);
});

The form

 <?php
      $attributes = array('class' => 'one_add', 'id' => 'add-'.$job->id.'');
      echo form_open('ajax/add_one_link', $attributes ); ?>
      <input type="text" class="one-link-<? echo $job->id; ?>" value="Url" />
      <input type="text" class="one-link-desc-<? echo $job->id; ?>" value="Description" />
      <button type="submit">Go!</button>

 <?php echo form_close(); ?>

The controller function

function one_link()
    {
            $this->load->model('one_add_model');

            $this->form_validation->set_rules('user_id', 'trim|required|xss_clean');
            $this->form_validation->set_rules('url', 'trim|required|xss_clean|strtolower');
            $this->form_validation->set_rules('desc', 'trim|required|xss_clean|strtolower');
            $this->form_validation->set_rules('one_id', 'trim|required|xss_clean');

            $user_id = $this->input->post('user_id');
            $url = $this->input->post('url');
            $desc = $this->input->post('desc');
            $one_id = $this->input->post('one_id');

            $this->one_add_model->add_url($user_id, $url, $desc, $one_id);
    }

The model

function add_url($user_id, $url, $desc, $one_id);
{
     $query_str = "INSERT INTO one_add (`user_id`, `url`, `desc`, `one_id` ) VALUES (?, ?, ?, ?)";
     $this->db->query( $query_str, array($user_id, $url, $desc, $one_id) );
}

This was finally showing

Message:  Undefined property: Home::$form_validation

And I just loaded the form validaton which was not loaded. But it was in another controller and was causing the same error. Not sure what happened … but it works now.

            $this->load->library('form_validation');
