How do I add pagination to codeigniter - codeigniter

Question

Below is how the ci controller looks like.
I'm just following tutorial from Youtube Channel.
How do you add pagination so the page only load 20 results per page ?
<?php
class Product_details extends CI_Controller{
function index(){
$this->load->library('pagination');
$this->load->model('product_model');
$data['userArray'] = $this->product_model->return_products();
$this->load->view('product_listing',$data);
}
}
View
<table>
<tr>
<th>ID</th>
<th>Product Name</th>
<th>Product Price</th>
<th>Product Image</th>
</tr>
<?php
foreach ($userArray as $key => $value) {
echo "<tr>
<td>".$value['id']."</td>
<td>".$value['post_id']."</td>
<td>".$value['price']."</td>
<td><img src=".$value['imageUrl']."/></td>
</tr>";
}
?>
</table>
Thank you

Answer 1

you can pass page number in the model.
Controller
<?php
class Product_details extends CI_Controller{
function index($pageNo){
$this->load->model('product_model');
$data['userArray'] = $this->product_model->return_products($pageNo);
$this->load->view('product_listing',$data);
}
}
Model
public function all($pageNo){
$pageNo -= 1;
$this->db->select("*")
->from('products')
->order_by('id',"ASC")
->limit(20, $pageNo * 20);
$query = $this->db->get();
return $query->result_array();

See the example how to add pagination.
Let's My controller is Dashboard.php and it's method is index.
Now configure pagination.
public function index()
{
$config['base_url'] = site_url('/dashboard/index/');
$config['total_rows'] = $this->dashboard_model->num_rows();
$config['per_page'] = 5;
$config['use_page_numbers'] = FALSE;
$this->pagination->initialize($config);
$data['data'] = $this->dashboard_model->all_blog($config['per_page'], $this->uri->segment(3));
$this->load->view("/dashboard/blog", $data);
}
Model is Dashboard_model.php
public function all_blog($limit, $offset)
{
$this->db->from('blogs');
$this->db->select('*');
$this->db->order_by("created_at", "desc");
$q = $this->db->get();
$data = $q->result_array();
return $data;
}
public function num_rows()
{
$this->db->from('blogs');
$this->db->select('*');
$this->db->order_by("created_at", "desc");
$this->db->limit($limit, $offset);
$q = $this->db->get();
$data = $q->num_rows();
return $data;
}
Now it's my view blog.php
<div class="table-responsive">
<table class="footable table table-stripped toggle-arrow-tiny" data-page-size="8" data-filter=#filter; id="filter">
<thead>
<tr>
<th></th>
<th>S.No</th>
<th>Title </th>
<th>Blog Image</th>
<th>Added For</th>
</tr>
</thead>
<tbody>
<?php
$count = $this->uri->segment(3, 0);
foreach ($data as $key) :
?>
<tr>
<td><input type="checkbox" class="i-checks" name="input[]"></td>
<td><?php echo ++$count; ?></td>
<td><?php echo $key['blog_title']; ?></td>
<td><img src="<?php echo $key['blog_image']; ?>" style="width: 150px; height: 80px" /></td>
<td><?php echo $key['user_type']; ?></td>
</tr>
<?php endforeach?>
</tbody>
</table>
</div>
<?php
echo $this->pagination->create_links();
?>
