How to Create Facebook Like Infinite Scroll Pagination using PHP and jQuery

Infinite scrolling pagination allows users to load new content automatically as they scroll down the page, without having to click on traditional “next” buttons. This type of pagination is often used on popular social media platforms such as Facebook, and can improve user experience by reducing the amount of clicks needed to navigate through large amounts of content.


Here is a step-by-step guide on how to create a Facebook-like infinite scroll pagination using PHP and jQuery:

  1. Create a database table to store your content, such as a table of blog posts or product listings. You can use a database management system such as MySQL to create and manage the table.

  2. Connect to the database in PHP and retrieve a set number of records (e.g. 10 records) to display on the page. To connect to the database, you can use the mysqli extension in PHP. You can retrieve the records using a SELECT query with a LIMIT clause. For example, to retrieve the first 10 records:

  3. scroll
  4. Use PHP to loop through the records and output the content onto the page in a HTML format. You can use the mysqli_fetch_assoc function to retrieve each row of the result set, and then use HTML to format the content:

  5. scroll-1
  6. Add the jQuery library to your page, and write the code to detect when the user has reached the bottom of the page. You can use the scroll event in jQuery to detect when the user has scrolled to the bottom of the page:

  7. scroll-2
  8. Write a jQuery function to send an AJAX request to a PHP script, passing the next set of records to be loaded. You can use the $.ajax function in jQuery to send the request:

  9. scroll-3
  10. Return the next set of records as JSON data in the PHP script. You can use the json_encode function in PHP to convert the records into JSON format:

  11. scroll-4

    In this example, the code first connects to the database using the mysqli_connect function, which takes the hostname, username, password, and database name as arguments. Then, it retrieves the offset value from the $_GET array and casts it to an integer.

    Next, it creates a query to retrieve the next set of records from the content table, limiting the number of records to 10 and using the offset value to determine which records to return. The LIMIT clause in the query limits the number of records returned, and the OFFSET clause determines the starting point for the records returned.

    Finally, the code loops through the returned records using the mysqli_fetch_assoc function, which fetches the next row of data from the result set as an associative array, and adds each row to the $data array. Finally, it uses the json_encode function to convert the $data array into a JSON string, which will be returned to the AJAX request.

  12. In the success function of the AJAX request, loop through the returned JSON data and append the new content to the page. You can use the $.each function in jQuery to loop through the data, and the append method to add the new content to the page:

  13. scroll-5
  14. Finally, wrap the content in a container element with an ID, such as a div with an ID of “content”. This will allow you to easily target the container in your jQuery code and append the new content:

  15. scroll-6

And that’s it! With these steps, you should have a working infinite scroll pagination system that loads new content automatically as the user scrolls down the page. Of course, you can customize the code to fit your specific needs, such as adjusting the number of records displayed per request, changing the look and feel of the content, and more.
