Pagination links not working - php

Question

I am trying to show my table in pagination.Links are coming but when i click on a 2 or 3 or anything it goes to /view_expenses/view&per_page= this. and i ll get a 404 error.why its not showing the rest data?
This is my controller
class View_expenses extends CI_Controller
{
public function __construct()
{
parent::__construct();
$data['title']= 'View Expenses';
$this->load->view('header_view',$data);
$this->load->model('emp_expenses_model');
$this->load->library('form_validation');
$this->load->helper('url');
$this->load->library('pagination');
}
public function index()
{
}
function view($offset=0){
$limit=5;
//$this->uri->segment(3);
$this->load->model('emp_expenses_model');
//$result['contents']=$this->emp_expenses_model->getRows($limit,$offset);
$result['countRows']=$this->emp_expenses_model->countRows();
$this->load->library('pagination');
$this->load->library('table');
$config=array(
'base_url' =>site_url ('/view_expenses/view'),
'total_rows' => $result['countRows'],
'per_page' => $limit,
'uri_segment' => 3,
'num_links' => 1,
);
//var_dump($config);
$this->db->limit(5);
$this->pagination->initialize($config);
$this->load->model('emp_expenses_model');
$this->data['view_expenses'] = $this->emp_expenses_model->get_all();
//$this->data['pagination'] = $this->pagination->create_links();
//var_dump($this->data['pagination']);die("jk");
$this->data['title'] = 'Payroll System';
$this->data['message'] = $this->session->flashdata('message');
$this->load->library('pagination');
$this->load->view('view_expenses', $this->data);
/*$this->load->view('add_list', $this->data);*/
}
This is my model
function getRows($limit,$offset)
{
$query=$this->db->select('expenses_id,id,dropdown,modeofpayment,amount')
->from('emp_expenses')
->limit($limit,$offset);
$result=$query->get()->result_array();
return $result;
//var_dump($result);
}
function countRows()
{
//$query="select count(*) as count from emp_expenses";
$result = $this->db->count_all_results('emp_expenses');
//$result=$this->db->query($query);
return $result;
//var_dump('countRows');
}
This is My View
<table cellspacing="0" cellpadding="2" border="0" id="tbl" style="width:100%">
<tr style="background-color:#045c97">
<?php echo $this->pagination->create_links()?>
<td class="heading">Employee ID</td>
<td class="heading">Drop Down</td>
<td class="heading">Mode OF Payment</td>
<td class="heading">Amount</td>
<td class="heading">Edit</td>
<td class="heading">Delete</td>
</tr>
<?php
foreach ($view_expenses as $m){
$list_id = $m['id'];
//print_r($list_id);die('adad');
//$m['username']='';
?>
<tr style="text-align:center;">
<td><?php echo $m['id'] ?></td>
<td><?php echo $m['dropdown'] ?></td>
<td><?php echo $m['modeofpayment'] ?></td>
<td><?php echo $m['amount'] ?></td>
<td>Edit</td>
<td>
<?php
echo anchor('view_expenses/delete_expenses/'.$list_id, 'Delete', array('onClick' => "return confirm('Are you sure you want to delete?')"));
?>
</td>

Answer 1

you need to use ? not & to separate a query string from the rest of request

Answer 2

Your query is written completely wrong, you must put a question mark before everything else in the URL.
foo://example.com:8042/over/there?name=ferret&color=brown#nose
\_/ \______________/\_________/ \______________________/ \__/
| | | | |
scheme authority path query fragment
Notice, the "Question-Mark", or query operator must come before any queries, but if there are more than one they should be seperated by the "&".
Try this:
/view_expenses/view?per_page=
As to the links not showing you what you want, your code is not correct in any way. Here is a tutorial in which I found easy to understand:
