I do like the Pagination library. However when I tried to use it, it became clear that it was a little lacking.
For example:
If I have a list and moving through it Pagination working fine.
http://domain/index.php/admin/list/index/50
However there is no option to have anything after Pagination’s index.
http://domain/index.php/admin/list/index/50/ID/asc
As the library will not consider it.
However using the code at the bottom, you can specify the information like:
$config['post_url'] = $data['order'].'/'.$data['orderDir'];
$this->pagination2->initialize($config);
This version works with 1.5.3 - 1.5.4
Hopefully something like this can be merge with the released CI, so I don’t have to worry about updates. :)
