CodeIgniter pagination won't go past first page - php

Question

I have a blog page of posts that I am trying to paginate using CodeIgniter. The numbering and limiting seem to be working fine, except I keep getting a 404 when I try to travel to another page.
The strange thing is the normal culprits that cause this issue are correct. The baseUrl and the uri_segment.
My controller looks like this:
$config = array();
$config["base_url"] = $this->config->site_url("/blog");
$config["total_rows"] = $this->blog_model->count();
$config["per_page"] = 2;
$config["uri_segment"] = 2;
$config["num_links"] = round($config["total_rows"] / $config["per_page"]);
$config['use_page_numbers'] = TRUE;
$this->pagination->initialize($config);
$page = ($this->uri->segment(2)) ? $this->uri->segment(2) : 0;
$this->load->view('blog', array(
'user' => $this->user,
'blog' => $this->blog_model->loadPosts($config['per_page'], $page),
'links' => $this->pagination->create_links(),
'footer' => $this->blog_model->loadFooter()
));
And then in my model I am grabbing the posts
public function loadPosts($limit, $start)
{
$this->db->limit($limit, $start);
$this->db->order_by("date", "desc");
//this loads the contact info
$query = $this->db->get('entries');
return $query->result();
}
My full URL is www.mysite.com/blog and then with the pagination it appears as www.mysite.com/blog/2.
For the base_Url I have also tried base_url() . "/blog";.
And I have tried setting the uri_segment to 1 and 3, but nothing seems to work.
As well I have tried playing around with the routing and have added just to see if it would do anything:
$route['blog/(:num)'] = 'blog/$1';

Answer 1

You can use this line of code if your code is inside the index method:
$route['blog/:any'] = "blog/index/$1";
Because you have used the segment(2), and you should change the blog/index/$1 to blog/:any.

Answer 2

Assuming the function name that contain your pagination code is index(), you should change the route to:
$route['blog/(:num)'] = 'blog/index/$1';
And in your index() function, add the $page parameter:
public function index($page = 1){
...

Answer 3

With your routes, try if you can to add as many :anys or :nums after as you like:
$route['blog'] = 'blog/index'; // For the first level
$route['blog/(:any)/(:any)'] = 'blog/index/$1/$2'; // For extra "uri" segments.
// base_url pagination
$config["base_url"] = base_url("blog"); // Is preferred

Answer 4

You can keep your other code as it is. Just add this at your routes.php file:
$route['blog/:num'] = "blog/index";
//Assumes your code is inside the index method.
//If not, use this way:
//$route['blog/:num'] = "blog/YOUR_METHOD_NAME";

Answer 5

You can't pass a parameter to the index() function of a controller like it is a random function.
If you try to do controller/var instead of controller/function/var, CodeIgniter will search for a function var() inside the controller which does not exists. That's what happen when you try to access blog/2: 2() isn't a function in your controller.
You can create a new function in your controller, let's say page(), and move your code inside. That way, you will call blog/page/2. Function page() will exists and will not get a 404. Also don't fordet to redefine your base_url for pagination.
$config["base_url"] = site_url("blog/page");
Another solution if you absolutely need the URL like /blog/2, routes:
$route['blog/(:any)'] = 'blog/index/$1';
Remap may also be a solution: http://www.codeigniter.com/user_guide/general/controllers.html#remapping
