Here's an example of what it should look like, ofcourse this is not a complete code but it's more like a guide on how to accomplish this.

### in your controller
$data['alpha'] = range('a', 'z');
// get the filter value from $_GET array
$alpha_filter = $this->input->get('alpha_filter');
// check if it's actually an alpha; otherwise it's set to null (no filter applied).
if( ! in_array($alpha_filter, $data['alpha'])) $alpha_filter = NULL;
// pass the filter to your model method so it adjusts the results approperiatly 
// Note: we're still passing the limit & offset so even with alpha_filter we're still able to paginate the result.
$data['records'] = $this->names_model->get_names($limit, $offset, $alpha_filter);



### in your view 
foreach( $alpha as $letter ) {
    echo anchor("controller/method?alpha_filter={$letter}", $letter);
}
