How to debug callback function

20 February 2017 - 03:42 PM



I'm new in GC, after 3 days of work, I created a little backend which is working, with some ajax function called, image resizing and more. All is working and it's clear than GC is a good piece of code, thank's


My problem is that I have a little complicated code which is called by a callback, and there is no error diplayed when it's occurs. So, it's very difficult to debug. What is the best method to get the error message.


Thank's for all.

Hello,the rec


I cant upload a file without problem, but when i delete the record in list view the record is deleted but the file stay on the server.

The problem is that I have absolutely no error message, what I can doing.


Please help.

I'm desperate (error loading library image crud)

05 April 2016 - 01:30 PM

I'm totally new in CI. I installed the library Image_CRUD as I do for GC, and I can load the grocery_CRUD Library, but if I uncomment $this->load->library('image_CRUD') I get this error : Unable to load the requested class: Image_CRUD

and an error 500 if I read the http error. I put all the image Crud files as I did for the GroceryCrud library with is ok.

Any idea ?


<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Main extends CI_Controller {
    function __construct()
        /* Standard Libraries of codeigniter are required */
        /* ------------------ */ 
    public function index()
        echo "<h1>Welcome to the world of Codeigniter</h1>";//Just an example to ensure that we get into the function
    public function carburant()
        $output = $this->grocery_crud->render();
    function _example_output($output = null)
    public function marque()
        $image_crud = new image_CRUD();
    //If your table have by default the "id" field name as a primary key this line is not required
    $output2 = $image_crud->render();
    function _example2_output($output = null)
/* End of file main.php */
/* Location: ./application/controllers/main.php */
