Go to our PHP, MySQL and AJAX CRUD Tutorial – Step by Step Guide!
Hi there! Today we are going to do a very simple yet useful script for your web apps.
A jQuery AJAX pagination with the help of a PHP pagination class. This is very easy to use and integrate with your project.
This code will load the paginated data via AJAX, we’ll have some loader image to make it look good and user friendly.
Paginated data was returned by our PHP script with the help of a Modified PS_Pagination Class (Yes, I modified it myself since I want to use this Awesome pagination class with jQuery.)
We are going to have the following files for today’s code:
1. images/ajax-loader.gif – for our loader animation
2. js/jquery-1.4.js – our favorite javascript library
3. libs/ps_pagination.php – the pagination class I modified
4. styles/style.css – style for our table data and page number navigation
5. db_connect.php – for database connection
6. index.php – our main UI
7. search_results.php – returns the data that will be displayed to index.php
Contents
Prepare our database table and data.
We’re gonna use the following sample table structure and data.
--
-- Table structure for table `users`
--
CREATE TABLE IF NOT EXISTS `users` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`firstname` varchar(32) NOT NULL,
`lastname` varchar(32) NOT NULL,
`email` varchar(32) NOT NULL,
`username` varchar(32) NOT NULL,
`password` varchar(32) NOT NULL,
`modified` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=56 ;
--
-- Dumping data for table `users`
--
INSERT INTO `users` (`id`, `firstname`, `lastname`, `email`, `username`, `password`, `modified`) VALUES
(28, 'John', 'Dalisay', '', 'john', 'john123', '2012-01-15 07:26:14'),
(39, 'Jem', 'Panlilio', '', 'jemboy09', 'jem123', '2012-01-15 07:26:46'),
(40, 'Darwin', 'Dalisay', '', 'dada08', 'dada123', '2012-01-15 07:25:34'),
(46, 'Jaylord', 'Bitamug', '', 'jayjay', 'jay123', '2012-01-15 07:27:04'),
(49, 'Justine', 'Bongola', '', 'jaja', 'jaja123', '2012-01-15 07:27:21'),
(50, 'Jun', 'Sabayton', '', 'jun', 'jun123', '2012-02-05 10:15:14'),
(51, 'Lourd', 'De Veyra', '', 'lourd', 'lourd123', '2012-02-05 10:15:36'),
(52, 'Asi', 'Taulava', '', 'asi', 'asi123', '2012-02-05 10:15:58'),
(53, 'James', 'Yap', '', 'james', 'jame123', '2012-02-05 10:16:17'),
(54, 'Chris', 'Tiu', '', 'chris', 'chris123', '2012-02-05 10:16:29');
Create our database connection file
Create db_connect.php file. The following code is how we connect to the database. We are using the PDO extension here.
<?php
// Database credentials
$db_host = "your_db_host";
$db_name = "your_db_name";
$db_username = "your_db_username";
$db_password = "your_db_password";
try {
// Get database connection
$conn = new PDO("mysql:host={$db_host};dbname={$db_name}", $db_username, $db_password);
}
// Handle connection error
catch(PDOException $exception){
echo "Connection error: " . $exception->getMessage();
}
?>
Prepare your loader image and jQuery
Create “images” folder and put your loader GIF image inside this folder. Generate and download your AJAX loader from the ajaxload.info website.
Create “js” folder. Download jQuery and put it inside the “js” folder.
If you’re not yet familiar with jQuery, I highly recommend studying our jQuery Tutorial for Beginners – Step By Step Guide!
User interface
Our user interface will be represented by our index.php file.
<!DOCTYPE HTML>
<html>
<head>
<title>jQuery AJAX and PHP Pagination Demo - codeofaninja.com</title>
<!-- Include custom CSS. -->
<link rel="stylesheet" type="text/css" href="styles/style.css" />
</head>
<body>
<div id='retrieved-data' style='height:15em;'>
<!--
This is where data will be shown.
-->
<img src="images/ajax-loader.gif" />
</div>
<script type = "text/javascript" src = "js/jquery-1.7.1.min.js"></script>
<script type = "text/javascript">
$(function(){
// show the first page
getdata(1);
});
function getdata(pageno){
// source of data
var targetURL = 'search_results.php?page=' + pageno;
// show loading animation
$('#retrieved-data').html('<img src="images/ajax-loader.gif" />');
// load to show new data
$('#retrieved-data').load(targetURL).hide().fadeIn('slow');
}
</script>
</body>
</html>
Getting the page data
This will be the code inside our search_results.php file, where our modified pagination class was used.
<?php
// Connect to database.
include 'db_connect.php';
// Include our pagination class / library.
include 'libs/ps_pagination.php';
// Query all data anyway you want
$sql = "select * from users ORDER BY firstname DESC";
/*
Now, we are going to use our pagination class.
This is a significant part of our pagination.
I will explain the PS_Pagination parameters:
> $conn is a variable from our config_open_db.php
> $sql is our sql statement above
> 3 is the number of records retrieved per page
> 4 is the number of page numbers rendered below
> null - We used null because we don't have any other parameters to pass
(i.e. param1=valu1¶m2=value2)
You can use this if you are going to use this class for search results.
The last parameter is useful because you will have to pass the search keywords.
*/
$pager = new PS_Pagination($conn, $sql, 3, 4, null);
// Our pagination class will render new recordset.
// Search results now are limited for pagination.
$rs = $pager->paginate();
// Count how many rows of data were returned.
$num = $rs->rowCount();
if($num >= 1 ){
// Create our table header
echo "<table id='my-tbl'>";
echo "<tr>";
echo "<th>Firstname</th>";
echo "<th>Lastname</th>";
echo "<th>Email</th>";
echo "</tr>";
// Loop through the records retrieved
while ($row = $rs->fetch(PDO::FETCH_ASSOC)){
echo "<tr class='data-tr' align='center'>";
echo "<td>{$row['firstname']}</td>";
echo "<td>{$row['lastname']}</td>";
echo "<td>{$row['email']}</td>";
echo "</tr>";
}
echo "</table>";
}else{
// If no records found
echo "No records found!";
}
// 'page-nav' CSS class is used to control the appearance of our page number navigation
echo "<div class='page-nav'>";
// Display our page number navigation
echo $pager->renderFullNav();
echo "</div>";
?>
Modified PS_Pagination Class
The previous section will not work without the PS_Pagination class we modified. Create “libs” folder. Open “libs” folder. Create ps_pagination.php file. Put the following code inside it.

Style page links
Style your page links, as for this tutorial, I used the following style.css:
<style type='text/css'>
/*you can change you table style here*/
#my-tbl {
background-color: #FFF;
color: black;
padding: 5px;
width: 700px;
border: thin solid red;
}
#th{
background-color: #000;
color: #FFF;
padding: 10px;
border-bottom: thin solid #000;
}
.data-tr{
background-color: #FFF;
color: #000;
border-bottom: thin solid #000;
}
.data-tr:hover {
background-color: #FAEFCF;
color: black;
padding: 5px;
border-bottom: thin solid #000;
}
.data-tr td{
padding: 10px;
margin: 0px;
}
/* you can change page navigation here*/
.page-nav{
margin: 10px 0 0 0;
padding: 8px;
}
.page-nav a{
border: none;
padding: 8px;
text-decoration: none;
background-color: #FFC;
border: thin solid #FC0;
color: #000;
}
.page-nav a:hover{
border: thin solid #FC0;
background-color: #FC0;
color: #fff;
}
/*this is the style for selected page number*/
.page_link{
padding: 8px;
}
</style>
I decided to delete the old MySQLi and PDO version pages and put it all in this one post. If you want to see the old comments, see MySQLi version old comments and PDO version old comments

Thank you for learning from our post about: jQuery AJAX and PHP pagination example!
RELATED TUTORIAL: PHP, MySQL and AJAX CRUD Tutorial – Step by Step Guide!
Hi @disqus_zDqMMpA1q7, you’re welcome! Please read my answer to your previous comment.
Hi @Pedro, thanks for the kind words about our work! To display more than 3 rows per page, change this:
$pager = new PS_Pagination($conn, $sql, 3, 4, null);
to this:
$pager = new PS_Pagination($conn, $sql, 10, 4, null);
Hi Mike,
Thanks for your reply. I finally find the solution :)
I have an other request please. I added search fields such as date range and two combobox. I performed à first test but it failed when i tried to access the second page. it not displayed expected results
In previous comments i read that i only have to change « TargetUrl » variable. Is this the only thing to change on your code? Or are there other part to modify?
I’ll post my code if needed.
Thanks,
Hi @disqus_zDqMMpA1q7, unfortunately the feature you described is not part of our tutorial and I cannot support it.
Dear Mike,
Thank you so much for this tutorial and it’s working fine but one this am struggling with is one I need to get by category id; it is not showing.
Hi @afaaro , you need to add the category ID as parameter. For example:
var targetURL = 'search_results.php?page=' + pageno + '&category_id=' + category_id;
Nice Work brother …. Its easy to manage for further use ….
Mike, I know my wife will hate you because I say this but I love you dude!!! LOVE YOU!!
@Mehti, WOW! You’re a funny dude haha! I love you too! *bromance*
Hello:
I have not read a single line of code, but noticed 1 very amazing thing. You are providing 3 methods of downloading. I think this is the first time I have ever seen that and because of that, AWESOME. Seriously, thank you for your advanced thinking.
Hi Mike,
Excellence tutorial. I’m new in this, I need little favour from you, how to I need to send 2 parameters when calling the result. Where and how should I go about this?
My parameters is like these: tmid=1&saluran=1
excellent tutorial! thanks mike… can you make a tutorial series, how to integrate this awesome pagination into awesome live search engine in ajax? thanks in advance… i subscribe for more updates and also waiting for this update also. keep on sharing, you rock…
Hi @3d47fad84c5309c9862ccdba115cb52f, thanks for dropping by! Thanks for the idea, I’m gonna try to make that tutorial series, thanks also for subscribing! :)
Great tutorial and very simple. Thank you Mike
You’re welcome OSb. :)
Sir i used javascript in my page and also give the value of variable but still not working
i am using code like
var targetURL = ‘search_results.php?page=’ + pageno + ‘&cityn=$city’;
@Muhammad – are you sure you included your parameters such as cityn on your javascript, like in my code, i only have ‘page’ as the parameter.
var targetURL = ‘search_results.php?page=’ + pageno;
yours should be something like:
var targetURL = ‘search_results.php?page=’ + pageno + ‘&cityn=php_generated_cityn_here’;
Dear Mike,
I have posted my code in pastbin please now tell me where is problem my project is stuck there. Please help me.
you can find code here http://pastebin.ca/2308539
@Muhammad Umer: Glad to know it is now working… By the way, you can paste your code next time in pastebin and link it here so we can see it properly, blogger does not allow code to be posted in comments..
Dear Mike,
your pagination is not working when we use variables in sql statement.
whenever i use simple sql query like
“select * from ads” then its worked great but when i use “select * from ads where cityname=$city” then in first page working good but when i click second page error occor Notice: Undefined index: cityn in D:xampphtdocstestdbads1.php
This is actual prob with me please help me i will very thankful to you.
Dear Respected Mike.
I am very tahnkful for your kind reply. but subcatn and cityn and mcn just the values that get from users the database fields is cityname, and type.
i show you whlo script that is here:
‘.$mcn.’->’.$sid;
?>
setDebug(true);
if ($result){
$rs = $pager->paginate();
if(!$rs) die(mysql_error());
while ($row=mysql_fetch_array($rs)){
Retrive Data here
echo $pager->renderFullNav();
echo ‘
‘;
echo “Post Ad“;
?>
@Muhammad Umer: Hi there! Please double check your database fields, subcatn, cityn and mcn seems like they does not exist.
Dear Sir,
$sql=mysql_Query(“select * from ads where cityname=’$city’ and type=’$sid’ order by id desc”);
Whenever i use this sql statment in php it work great in first page but next page i got errors
like:
Undefined index: subcatn in D:xampphtdocstestdbads1.php on line 17
Notice: Undefined index: cityn in D:xampphtdocstestdbads1.php on line 18
Notice: Undefined index: mcn in D:xampphtdocstestdbads1.php on line 19
Query returned zero rows.
What i do now?
thanks for advance
download worked fine for me.
Nice script! Learned a lot from it, Im new to dealing with ajax
Can anybody re-upload please?
The download isn’t working.
Thanks.
I have rewritten your code to work with MongoDB. It works great. But I have a problem now. I had some ajax request and they don’t work.
For example, I can’t get this:
var row = $(this).parent().parent();
Probably because the table is not render and I can’t find elements. What should I do?
I like your script ,I would like to implement this script to more then 10 pages.Its is posiple to pass the filename to the javascript function getdata(2) .
sup… got any hints on what to do when using it with jQuery mobile? teh html gets injected properly but it doesn’t get styled like the other elements on the page. some refresh trigger or something? cheers
ease on implementing and configuration. This code rocks!
Thanks ninja guy
Nice code – I will try and see if I can get it working in a project I currently have.
Helen Neely
Hi I think this is just the ticket for what I’m looking for but getting an error.
Method name must be a string..line 111
Line 111 $result=$pager->$paginate();
Line 112 $num=mysql_num_rows($results);
I cannot see anything wrong..
Any help would be grateful.
Hello thanks for your script. Any clue abut how to use it with a MySQLi connection? I’m always getting Fatal error: Call to a member function query() on a non-object but I don’t really know how to get rid of it.
Many thanks
Franz
MSSQL does not support the SQL Limit statement. Try using TOP instead.
@psihologie: You’re welcome. :)
@Joni Wilson: Sorry dude I’m not using MSSQL and not familiar with its syntax..
HI, I try to use this magnifique pagination with MSSQL but i have on error in LIMIT
$rs = @mysql_query($this->sql . ” LIMIT {$this->offset}, {$this->rows_per_page}” );
I change mysql_query for mssql_query and LIMIT to TOP, but i have a error:
Warning: mssql_fetch_array(): supplied argument is not a valid MS SQL-result resource
Can you Help me???
wooooooow, great man! thank you so much, i am immediately implementing this on my website! this if of great help! i was looking for a dynamic pagination solution using ajax, and there you go… you have it :) thanks!
@Joe: I just saw you got it working now, nice. :)
I keep getting an error when I click the links to go to another page:
“Uncaught ReferenceError: getdata is not defined”
URL:http://www.25idtacops.com/pbsvss.php
Thanks man, look at the bottom part of my CSS code, you’ll see the .page_link class. That class was used for the current/selected page. You can play around with that to change the link colour/style. :)
hi i do like your cool and easy pagination class..however is it possible to have pages that would have been edited to have a different link colour.
For example say i am paginating user comments and have 100 pages of comments and i have 20 records per page and 5 page links at the bottom.How can i have say the page 3 link show a different colour to indicate that a comment has been made on that page?
i am new to php and ajax
Hahahahahaha! Thanks @Anonymous! :)
If you were a girl, I will definitely marry you. I love you… Great work buddy, keep it up…
@Anonymous_1: Can you give me a link to a screenshot or page of your problem?
@Anonymous_2: You’re welcome. :)
Ty =)
Great script!. Just one weird issue. The css on my target page is a little goofy when going through the index page but looks just fine when I go directly to it.
Any thoughts?
Thanks again for the great script.
Thanks sir :)
Wow nice tut, ninja mike! Napaka detailed! :)
