Question

I know how to create pagination and generate a table containing information from database in codeigniter, but I don’t how to display the serial numbers for each row in the table. Example:

SL.  Name           Email
1.  Srijon      [e-mail]
2.  Jake        [e-mail]

Would you please kindly show me how to do that? Thanks in advance

Here is the controller for how I create pagination and generate table (without serial numbers)

 function index(){

            $this->load->library('pagination');
            $this->load->library('table');
            $this->table->set_heading('Student ID','Student Name','Batch','Edit','Delete');

            $config['base_url'] = 'http://localhost/coaching/index.php/student_list/index';
            $config['total_rows'] = $this->db->get('student')->num_rows();
            $config['per_page'] = 15;
            $config['num_links'] = 20;
            $config['full_tag_open'] = '<div id="pagination" align="center">';
            $config['full_tag_close'] = '</div>';

            $this->pagination->initialize($config);
            $data['tab'] = "Student List";              
            $this->load->model('mod_studentlist');
            $data['records']= $this->mod_studentlist->student_list();
            $data['main_content']='studentlist';
            $this->load->view('includes/template',$data);

        }   

Here’s my model

                function student_list()
    {   
        $config['per_page'] = 10;
        $this->db->select('studentid, studentname, batch');
        $this->db->order_by("studentid", "desc"); 
        $rows = $this->db->get('student',$config['per_page'],$this->uri->segment(3))->result_array();


        foreach ($rows as $count => $row)
            {
             $rows[$count]['studentname'] = anchor('student_list/get/'.$row['studentid'],$row['studentname']);
             $rows[$count]['Edit'] = anchor('update_student/update/'.$row['studentid'],'Update');
             $rows[$count]['Delete'] = anchor('report/'.$row['studentid'],'Delete');

            }
        return $rows;
    }

Here’s my view file

                 <?php echo $this->table->generate($records);?>
                    <?php  echo $this->pagination->create_links();?>
                    <script type="text/javascript" charset="utf-8">
                        $('tr:odd').css('background','#EAEAEA');
                        </script>

You should create a variable inside your model function:

<?php
function student_list()
{   
    $config['per_page'] = 10;
    $this->db->select('studentid, studentname, batch');
    $this->db->order_by("studentid", "desc"); 
    $rows = $this->db->get('student',$config['per_page'],$this->uri->segment(3))->result_array();

    $sl = $this->uri->segment(3) + 1; // so that it begins from 1 not 0

    foreach ($rows as $count => $row)
        {
         array_unshift($rows[$count], $sl.'.');
         $sl = $sl + 1;

         $rows[$count]['studentname'] = anchor('student_list/get/'.$row['studentid'],$row['studentname']);
         $rows[$count]['Edit'] = anchor('update_student/update/'.$row['studentid'],'Update');
         $rows[$count]['Delete'] = anchor('report/'.$row['studentid'],'Delete');
        }
    return $rows;
}

and modify your controller:

<?php
function index() {
    $this->load->library('pagination');
    $this->load->library('table');
    $this->table->set_heading('SL.', 'Student ID','Student Name','Batch','Edit','Delete');
    ....
