Simple Ajax Pagination With PHP

Submitted by razormist on Thursday, March 2, 2017 - 17:12.

In this tutorial we will create a Simple Ajax Pagination With PHP. Ajax is a client-side script that communicates to a server/database without the need for a page refresh. It is mostly use by a well known websites like facebook. AJAX is a new technique for creating better, faster, and more interactive web applications. Let's start coding... Creating The Database Connection To create the connection copy/paste the code below and name it 'connect.php'

<?php
	$conn = new mysqli("localhost", "root", "", "db_pagination");
	if(!$conn){
		die("Fatal Error: Connection Failed!");
	}
?>

Creating A Mark Up To create this form, just copy/paste the code below and name it 'index.php'

<!DOCTYPE html>
<html lang = "en">
	<head>
		<link rel = "stylesheet" type = "text/css" href = "css/bootstrap.css"/>
		<meta charset = "UTF-8" name = "viewport" content = "width=device-width, initial-scale=1" />
	</head>
<body>
	<nav class = "navbar navbar-default">
		<div class = "container-fluid">
			<a class = "navbar-brand" href = "https://sourcecodester.com">Sourcecodester</a>
		</div>
	</nav>
	<div class = "row">
		<div class = "col-md-3"></div>
		<div class = "col-md-6 well">
			<h3 class = "text-primary">Simple Ajax Pagination With PHP</h3>
			<hr style = "border-top:1px dotted #000;"/>
			<div class = "table-responsive" id = "load_data">	
 
			</div>	
		</div>
	</div>
</body>
<script src = "js/jquery-3.1.1.js"></script>	
<script src = "js/ajax.js"></script>
</html>

Creating The PHP Query This is where the data will be display. To make the result display, just copy/paste the code below then name it 'book_data.php'

<?php
	require_once 'connect.php';
 
	$record_per_page = 5;
 
	$page = "";
	$result = "";
 
	if(ISSET($_POST['page'])){
		$page = $_POST['page'];
	}else{
		$page =  1;
	}
 
	$start = ($page - 1) * $record_per_page;
 
	$q_book = $conn->query ("SELECT * FROM `page` LIMIT $start, $record_per_page") or die(mysqli_error());
 
	$result .="
		<table class = 'table table-bordered'>
			<thead>
				<tr>
					<th colspan = '2'><center>List of Books</center></th>
				</tr>
				<tr>
					<th>Book #</th>
					<th>Title</th>
				</tr>
			</thead>
			<tbody>
	";
 
	while($f_book = $q_book->fetch_array()){
		$result .= "
			<tr>
				<td style = 'width:50%;'>".$f_book['book_id']."</td>
				<td style = 'width:50%;'>".$f_book['title']."</td>
			</tr>
		";
	}
	$result .= "
		</tbody></table>
	";
 
	$q_page = $conn->query("SELECT * FROM `page`") or die(mysqli_error());
	$v_page = $q_page->num_rows;
	$total_pages = ceil($v_page/$record_per_page);
	for($i = 1; $i <= $total_pages; $i++){
		$result .="<span class = 'pagination' style = 'cursor:pointer; margin:1px; padding:8px; border:1px solid #ccc;' id = '".$i."'>".$i."</span>";
	}
	$result .="
		<span class = 'pull-right'>Page of ".$page." out of ".$total_pages."</span>
	";
	echo $result;
?>

Creating The Ajax Script To make the query works, we will have to make a ajax function that calls back PHP Query. Just copy/paste the code below then name it 'ajax.js'

$(document).ready(function(){
	load_data();
	function load_data(page){
		$.ajax({
			url: 'book_data.php',
			method: 'POST',
			data: {
				page: page
			},
			success: function(res){
				$('#load_data').html(res);
			}
		});
	}
 
	$(document).on('click', '.pagination', function(){
		$page = $(this).attr('id');
		load_data($page);
	});
});

The function load_data will try to send the index of the page number, and calls back the result from the PHP query. There you have it we created a simple pagination using ajax. I hope that this tutorial helps you to your projects. For more updates and tutorials just kindly visit this site. Enjoy Coding!!
