-

Hi Geeks, We have gone through some user requests for pagination code for php mysql project.So we have created a simple class where you can easily create pagination for any grid or listing. following are the simple steps for making a pagination system in php.
Step 1: Create a class file ‘Paginator.class.php’ in your project with following code snippet
_conn = $conn; $this->_query = $query; $rs= $this->_conn->query( $this->_query ); $this->_total = $rs->num_rows; } public function getData( $limit = 10, $page = 1 ) { $this->_limit = $limit; $this->_page = $page; if ( $this->_limit == 'all' ) { $query = $this->_query; } else { $offset=( ( $this->_page - 1 ) * $this->_limit ); $query = $this->_query . " LIMIT " . $offset . ", $this->_limit"; } $rs = $this->_conn->query( $query ); $results=array(); while ( $row = $rs->fetch_assoc() ) { $results[] = $row; } $result = new stdClass(); $result->page = $this->_page; $result->limit = $this->_limit; $result->total = $this->_total; $result->data = $results; return $result; } public function append_existing_query_string($qstring) { if(isset($_GET)) { foreach($_GET as $k=>$v) { $qstring.="&".$k."=".$v; } } return $qstring; } public function createLinks( $links, $list_class ) { if ( $this->_limit == 'all' ) { return ''; } $last = ceil( $this->_total / $this->_limit ); $start = ( ( $this->_page - $links ) > 0 ) ? $this->_page - $links : 1; $end = ( ( $this->_page + $links ) < $last ) ? $this->_page + $links : $last; $html = '- ';
$class = ( $this->_page == 1 ) ? "disabled" : "";
//
$qstring='?limit=' . $this->_limit . '&page=' . ( $this->_page - 1 );
$qstring=$this->append_existing_query_string($qstring);
//
$html .= '
- « '; if ( $start > 1 ) { // $qstring='?limit=' . $this->_limit . '&page=1'; $qstring=$this->append_existing_query_string($qstring); // $html .= '
- 1 '; $html .= '
- ... '; } for ( $i = $start ; $i <= $end; $i++ ) { $class = ( $this->_page == $i ) ? "active" : ""; // $qstring='?limit=' . $this->_limit . '&page=' . $i; $qstring=$this->append_existing_query_string($qstring); // $html .= '
- ' . $i . ' '; } if ( $end < $last ) { $html .= '
- ... '; // $qstring='?limit=' . $this->_limit . '&page=' . $last; $qstring=$this->append_existing_query_string($qstring); // $html .= '
- ' . $last . ' '; } $class = ( $this->_page == $last ) ? "disabled" : ""; $qstring='?limit=' . $this->_limit . '&page=' . ( $this->_page + 1 ); $qstring=$this->append_existing_query_string($qstring); $html .= '
- » '; $html .= '
Step 2: Include the paging class before extracting data to show
Step 3: Now extract the data for any page as following
getData( $limit, $page ); ?>Step 4 : Now we are ready with data. So just showing the data and links as following
Show the data first and after it showing the pagination links as following:
<th>Customer Id</th>
<th>Customer Name</th>
<th>Customer Email</th>
<th>Customer Address</th>
</tr>
</thead>
<tbody>
<?php
if(isset($results) && count( $results->data ) > 0){
for( $i = 0; $i < count( $results->data ); $i++ ) { ?>
<tr>
<td><?php echo $results->data[$i]['id']; ?></td>
<td><?php echo $results->data[$i]['name']; ?></td>
<td><?php echo $results->data[$i]['email']; ?></td>
<td><?php echo $results->data[$i]['address']; ?></td>
</tr>
<?php }
} ?>
</tbody>
</table>
Show the paging links after the data
createLinks( $links, $class="pagination"); ?>
