Codeigniter customizing pagination links

Question

I'm using CodeIgniter pagination,Consider 20 links pagination

Condition 1 : Show 5 links initially like below

1 2 3 4 5 next>>

Condition 2 : When 5th link is clicked, the number 5 should place two digits on either side like below

<<previous 3 4 5 6 7 next>>

I have change

$config["num_links"] = 2;

this works fine for condition 2 but initially it gives 3 links like below.

 1 2 3 next>>

When num_links changed to 4

$config["num_links"] = 4;

this works fine for condition 1 but fail to meet condition 2

Answer 1

CodeIgniter does not have any inbuilt configuration for this.

When you say: $config["num_links"] = 2; it just means add 2 previous and 2 next to the current page.

When you are in the first page, there is no previous and it adds two next so you get:

1 2 3 next>>

Same logic for the behavior when you do $config["num_links"] = 4;

If you really want to do it how you described you will have to extend the CI Pagination class with your own class:

class MY_Pagination extends CI_Pagination {...

And then add your custom pagination functions to it.
