Codeigniter- Pagination-showing empty data after delete/edit - php

Question

I am listing the registered employee from the db and showing 10 employee per page. I'm using codeigniter pagination for the purpose.
If I deleted an employee in page 2, after deleting I need to go to page 2 showing rest of the employees in page 2.
View:
<a href="<?php echo $path;?>welcome/delete_employee/employeeid/<?php echo $row->empID;?>/pageNum/<?php echo $currentPage; ?>" onClick="return delAlert()";><img src="<?php echo $path;?>/img/delete.png" height="30px" width="30px" /></a>
Controller:
public function delete_employee()
{
$session_id = $this->session->userdata('logged_in');
if($session_id) {
$array = $this->uri->uri_to_assoc(3);
$count=$array['pageNum']-1;
$i=$count*10;
$this->load->model('welcomemodel','m',true);
$this->m->deleteemployee($array['employeeid']);
$config = array();
$config["base_url"] = base_url() . "welcome/employee";
$config["total_rows"] =$this->m->employee_count();
$config["per_page"] = 10;
$config["uri_segment"] = $array['pageNum'];
$data['showData'] = $this->m->getEmployee($config["per_page"], $i);
$this->pagination->initialize($config);
$data["links"] = $this->pagination->create_links();
$data["currentPage"] =$array['pageNum'];
$this->load->view('header');
$this->load->view('employee',$data);
} else {
$this->load->view('session_expired');
}
}
Model:
public function deleteemployee($employeeid)
{
$this->db->where('empID',$employeeid);
$this->db->delete('employee');
return $this->db->affected_rows();
}
public function getEmployee($limit, $start)
{
$this->db->limit($limit, $start);
$this->db->select()
->from('employee')
->order_by('emp_fname');
$this->db->join('service', 'employee.serviceID = service.serviceID','left');
$query=$this->db->get();
return $query;
}
public function employee_count()
{
return $this->db->count_all("employee");
}
But now the pagination link shows first page's link,even though contents of second page is displayed....

Answer 1

model method
public function employee_count()
{
$result = $this->db->get('employee');
if ($result->num_rows() > 0) {
//employee record available
return true;
}
else
{
// employee record not available
return false;
}
}
View
<?php
$getData = $this->[your model name]->getEmployee($limit, $start);
?>
<?php if ($getData): ?>
//Your Pagination Part Here.....
<?php else: ?>
// else Nothing
<?php endif ?>
