Codeigniter Paginaton Next button is not working

Question

I am trying to display information from database. I have set $config['per_page'] to 2, in my view file I can see the information I want but when I click on the next button it doesn't change anything. The database values remain same and the current page remains the first page too.

Would you please kindly help me figure out the problem?

Thanks in Advance :)

Controller:

 function index($id){                   
    $this->load->library('pagination');                                 
    $config['base_url'] = site_url().'Student_fee_status/index/'.$id;

    $this->db->select('*');
    $this->db->from('studentpayment1');
    $this->db->where('studentid', $id); 

    $query = $this->db->get('');
    $numrows=$query->num_rows();                    

    $config['total_rows'] = $numrows;
    $config['per_page'] = 2;
    $config['uri_segment'] = '2'; 
    $config['num_links'] = 20;
    $config['full_tag_open'] = '<div class="pagination" align="center">';
    $config['full_tag_close'] = '</div>';

    $this->pagination->initialize($config);                 
    $this->load->model('Mod_student_fee_status');

    $data['records']= $this->Mod_student_fee_status->fee_status($id,$config['per_page'],$config['uri_segment']);
    $data['main_content']='view_student_fee_status';

    $this->load->view('includes/template',$data);                   
}   

My Model :

function fee_status($id,$perPage,$uri_segment) { 
    $this->db->select('*');
    $this->db->from('studentpayment1');
    $this->db->where('studentid', $id); 

    $getData = $this->db->get('', $perPage, $uri_segment);

    if($getData->num_rows() > 0)
        return $getData->result_array();
    else
        return null;
}

EDIT

When the page first loads the link looks like this- http://localhost/sundial/Student_fee_status/index/1006/ but when I click on the next page it looks like this- http://localhost/sundial/Student_fee_status/index/1006/2

My View File:

<h1>Payment Status</h1>     
<?php if(count($records) > 0) { ?>
    <table id="table1" class="gtable sortable">

                <th>Balance</th>

                            echo "<font color=\"red\">$balance</font>";

Answer 1

You are telling the pagination library to use $config['uri_segment'] = '2'; - the second segment of your uri.

When this is your url: http://localhost/sundial/Student_fee_status/index/1006/ I am guessing this is your base_url: http://localhost/sundial/

In this case your segments are:

1. Student_fee_status - your controller
2. index - the controllers method you are calling
3. 1006 - the argument you are calling the controllers method with
4. this should be the argument for pagination

Try this

$config['uri_segment'] = '4';

instead of

$config['uri_segment'] = '2';

edit:

$data['records']= $this->Mod_student_fee_status->fee_status($id,$config['per_page'],$config['uri_segment']);

I think this line contains another error.

You pass your model the information which uri_segment is used by the pagination library. That should be 4 now. However, your model uses this value to specify an offset in your query. This means you always put an offset of 4 into your query. But I think what you really want to do is, pass the model the VALUE of the 4th uri_segment.

I would try this instead:

 $data['records']= $this->Mod_student_fee_status->fee_status($id,$config['per_page'],$this->uri->segment($config['uri_segment']));
