In this post we will learn how to use flexi grid with php. Flexi grid is very useful jquery plug-in for listing elements. It has many features like sorting, pagination and reloading. Flexi grid provides flexibility to the developer to add hooks with grid event. This is magical combination flexi grid with PHP. Flexi grid is open source project.
We will implement flexi grid with PHP in MVC pattern.
Below are simple steps to with full db script:
Step 1: First we will create a table into db.

CREATE TABLE IF NOT EXISTS `tbl_issues` (
`ISSUEID` int(11) NOT NULL AUTO_INCREMENT,
`issueName` varchar(255) NOT NULL
PRIMARY KEY (`ISSUEID`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
INSERT INTO `tbl_issues` (`ISSUEID`, `issueName`) VALUES
(10, 'issue3');
Step 2: fetch the data in model class

function getAssignedIssues($options){
global $wpdb;
$page = ($options['page'] > 1) ? $options['page'] : 1;
$offset = $options['rp'];
$limit = ($page-1)*$offset;
switch($options['sortname']){
case 'issueName':
default:
$options['sortname'] = 'Issue.ISSUEID';
break;
}
$records = array();
$sql = "
SELECT
Issue.ISSUEID AS id,
Issue.issueName AS issueName,
FROM
tbl_issues";
$countQuery = "select count(Issue.ISSUEID) from tbl_issues AS Issue";
$sql .= " ORDER BY ".$options['sortname']." ".$options['sortorder']."
LIMIT ". $limit .",". $offset ."";
$total = $wpdb->get_var($countQuery);
$records = $wpdb->get_results($sql, ARRAY_A);
return array(
'page' => $page,
'total' => $total,
'records' => $records
);
}
Step 3:After fetching data from database,we will call model method into controller class and format the results according flexi grid format.

public function getIssues() {
global $current_user;
$data = $this->User->getAssignedIssues(array(
'page' => isset($post['page']) ? intval($post['page']) : 1,
'rp' => isset($post['rp']) ? intval($post['rp']) : 5,
'sortname' => isset($post['sortname']) ? trim($post['sortname']) : '',
'sortorder' => isset($post['sortorder']) ? trim($post['sortorder']) : 'ASC'
));
$response = array(
'page' => $data['page'],
'total' => $data['total'],
'rows' => array()
);
foreach($data['records'] as $record){
$response['rows'][] = array(
'id'=> $record['id'],
'cell' => array(
'id' => $record['id'],
'issueName' => $record['issueName']
)
);
}
$this->render_view(_default', array(
'locals' => array(
'response' => $response
)
));
exit(0);
}
Step 4: Now we will add css and js library file into head section of view.

<link rel='stylesheet' id='css-flexigrid-css' href='http://localhost/test/css/flexigrid.css?ver=3.4.2' type='text/css' media='all' />
<script type='text/javascript' src='http://localhost/testjs/jquery.base64.js'></script>
<script type='text/javascript' src='http://localhost/test/js/flexigrid.js'></script>
Step 5: Create table for bind grid.
1
<table class="table table-bordered table-hover" style="display: non" id="issues-listing-grid"></table>
Step 6: After adding jquery and flexi grid js file in head part of view file. We will format grid layout. we will add below code in bottom of view file.

var issueListingGrid = null,

Result:
