Hi erevyone i have some trouble when i'm about to upload my program to hosting. I've made configuration changes such as base_url, database, etc. But it show me an error like this :

Line Number: 11

Backtrace:

Here is my controller look like :

<?php

defined('BASEPATH') or exit('No direct script access allowed');

class Home extends My_Controller
{

    public function index($page = null)
    {
        $data['title']  = 'Home | Omid Health Style';
        $data['content']    = $this->home->select(
            [
                'product.id', 'product.slug', 'product.title AS product_title', 'product.description',
                'product.image', 'product.price', 'product.is_available', 'product.weight',
                'category.title AS category_title', 'category.slug AS category_slug'
            ]
        )
            ->join('category')
            ->where('product.is_available', 1)
            ->paginate($page)
            ->get();
        $data['total_rows'] = $this->home->where('product.is_available', 1)->count();

        $this->home->table = 'blog';
        $data['blogs'] = $this->home->select(
            [
                'blog.id', 'blog.slug', 'blog.title AS blog_title', 'blog.description', 'blog.content',
                'blog.image', 'blog_category.title AS blog_category_title', 'blog_category.slug AS blog_category_slug'
            ]
        )
            ->join('blog_category')
            ->paginate($page)
            ->get();
        $data['total_rows'] = $this->home->count();

        $data['page']   = 'pages/home/index';

        $this->view($data);
    }
}

Here is my Home_model.php :

<?php

defined('BASEPATH') or exit('No direct script access allowed');

class Home_model extends MY_Model
{

    public $table    = 'product';
    protected $perPage  = 8;
}

/* End of file Home_model.php */

And here is MY_Controller.php and MY_Model.php in my core folder, because i made a custom configuration like this :

<?php

defined('BASEPATH') or exit('No direct script access allowed');

class My_Controller extends CI_Controller
{


    public function __construct()
    {
        parent::__construct();
        $model = strtolower(get_class($this));

        if (file_exists(APPPATH . 'models/' . $model . '_model.php')) {
            $this->load->model($model . '_model', $model, true);
        }
    }


    // Load view with Default Layouts
    public function view($data)
    {
        $this->load->view('layouts/app', $data);
    }
}

<?php


defined('BASEPATH') or exit('No direct script access allowed');

class MY_Model extends CI_Model
{

    protected $table    = '';
    protected $perPage  = 5;


    public function __construct()
    {
        parent::__construct();

        if (!$this->table) {
            $this->table = strtolower(
                str_replace('_model', '', get_class($this))

Could you guys please explain to me, why i got error like this? FYI. In my local server the code is working well.

Answer 1

Not definitely sure about your server. The server that I deploy my applications on throws an error when I include more than 1 uppercase in Filename, controller class name, or model class name.

try replacing your "My_Controller" to "My_controller".
