Load more data on page scroll using jQuery, Ajax and PHP

Pagination, also known as paging, is the process of dividing a document into discrete pages.The dynamic record is loaded from the server automatically while scrolling page down. Infinite scrolling is a user-friendly way to load additional content on the web application. In this post, We have share how to implement Load more data on page scroll using jQuery, Ajax and PHP. This is a very simple example, you can just copy paste and change according to your requirement.

Before started to implement the Load more data on page scroll using jQuery, Ajax and PHP look files structure:

load-data-on-page-scroll-using-php-mysql-jquery
- css
  - style.css
  - shimmer.css
- images
- templates
  - header.php
  - footer.php
- config.php
- fetch_record.php
- index.php

Step 1: Create the database and Table

Run the following script against MySQL to create the database news table.

  -- Table structure for table `news`

  CREATE TABLE `news` (
    `id` int(11) NOT NULL,
    `title` varchar(255) DEFAULT 'NULL',
    `description` text NOT NULL,
    `name` varchar(255) NOT NULL,
    `email` varchar(255) NOT NULL,
    `user_pic` varchar(255) NOT NULL,
    `created_date` varchar(12) NOT NULL
  ) ENGINE=InnoDB DEFAULT CHARSET=latin1;

  -- Dumping data for table `news`

  INSERT INTO `news` (`id`, `title`, `description`, `name`, `email`, `user_pic`, `created_date`) VALUES

MODIFY `id` int(11) NOT NULL AUTO_INCREMENT, AUTO_INCREMENT=18;

Step 2: Database Configuration (config.php)

The config.php file is used to connect and fetch record from database. You should change your username, password and database name. See the config.php file below.

<?php
  $dbHostname = "localhost";
  $dbName = "test_DB";
  $dbUsername = "root";
  $dbPassword = "";

  try {
    $conn = new PDO("mysql:host=$dbHostname;dbname=$dbName", $dbUsername, $dbPassword);
    // set the PDO error mode to exception
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
  }
  catch(PDOException $e) {
    echo "Connection failed: " . $e->getMessage();
  }
?>

<?php

$dbHostname = "localhost";

$dbName = "test_DB";

$dbUsername = "root";

$dbPassword = "";

try {

$conn = new PDO("mysql:host=$dbHostname;dbname=$dbName", $dbUsername, $dbPassword);

// set the PDO error mode to exception

$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

}

catch(PDOException $e) {

echo "Connection failed: " . $e->getMessage();

}

Step 3: Load Data from Database (fetch_record.php)

The fetch_record.php file is called by the Ajax request on page scroll.

<?php
  include_once('config.php');
  $start = $_POST['start'];
  $limit = $_POST['limit'];

  try { 
    $stmt = $conn->prepare("SELECT id, title, description, name, email, user_pic, created_date FROM news LIMIT $limit OFFSET $start");
      $stmt->execute();
      $query = $stmt->fetchAll(\PDO::FETCH_ASSOC);

      foreach ($query as $key => $element) {  
        echo '<div class="card gedf-card" style="margin: 5px;">
          <div class="card-header">

                          <img class="rounded-circle" width="45" src="images/'.$element['user_pic'].'" alt="'.$element['title'].'">
                      </div>
                      <div class="ml-2">
                          <div class="h5 m-0">@'.$element['name'].'</div>

                  <div>                   
                  </div>
              </div>

          </div>
          <div class="card-body">
              <div class="text-muted h7 mb-2"> <i class="fa fa-clock-o"></i> '.date('j M Y g:ia', $element['created_date']).'</div>

  } catch (PDOException $e) {
      echo 'Connection failed: ' . $e->getMessage();

<?php

include_once('config.php');

<p class="card-text">'.$element['description'].'</p>

</div>

</div>';

}

} catch (PDOException $e) {

echo 'Connection failed: ' . $e->getMessage();

}

Step 4: Create index.php

Create a PHP file index.php to create HTML to display dynamically loaded record on page scroll.

<?php include_once('templates/header.php'); ?>
<section class="showcase">
  <div class="container">
    <div class="pb-2 mt-4 mb-2 border-bottom">
      <h2>Load more data on page scroll using jQuery, Ajax and PHP</h2>
    </div>
    <div class="row">       
      <div class="col-md-12 gedf-main">
        <span id="load-data"></span>
        <span id="load-data-msg"></span>
      </div>       
    </div>
  </div>
</section>
<?php include_once('templates/footer.php'); ?>

<script>
  jQuery(document).ready(function() {
    var limit = 5;
    var start = 0;
    var flag = "inactive";
    function placeHolderShimmer(limit) {
      var bindHTML = '';
      for(var counter=0; counter<limit; counter++) {
        bindHTML += '<div class="timeline-item">';
          bindHTML += '<div class="animated-background">';
            bindHTML += '<div class="background-masker header-top"></div>';
            bindHTML += '<div class="background-masker header-left"></div>';
            bindHTML += '<div class="background-masker header-right"></div>';
            bindHTML += '<div class="background-masker header-bottom"></div>';
            bindHTML += '<div class="background-masker subheader-left"></div>';
            bindHTML += '<div class="background-masker subheader-right"></div>';
            bindHTML += '<div class="background-masker subheader-bottom"></div>';
            bindHTML += '<div class="background-masker content-top"></div>';
            bindHTML += '<div class="background-masker content-first-end"></div>';
            bindHTML += '<div class="background-masker content-second-line"></div>';
            bindHTML += '<div class="background-masker content-second-end"></div>';
            bindHTML += '<div class="background-masker content-third-line"></div>';
            bindHTML += '<div class="background-masker content-third-end"></div>';
          bindHTML += '</div>';
        bindHTML += '</div>';
      }
      jQuery("#load-data-msg").html(bindHTML);
    }
    // call function
    placeHolderShimmer(limit);
    function getData(limit, start) {
      jQuery.ajax({
        url:"fetch_record.php",
        method:"POST",
        data:{limit:limit, start:start},
        dataType: 'html',
        cache: false,
        success:function(html) {
          if(html == '')  {
            jQuery('span#load-data-msg').html('<div class="text-muted" style="font-weight:bold; font-size:18px; text-align:center;">No more result yet!</div>');
            flag = 'active';
          }  else {
            jQuery('span#load-data').append(html);
            jQuery('span#load-data-msg').html("");
            flag = 'inactive';
          }
        }
      })
    }
    if(flag == 'inactive') {
      flag = 'active';
      getData(limit, start);
    }
    jQuery(window).scroll(function() {
      if(jQuery(window).scrollTop() + jQuery(window).height() > jQuery("span#load-data").height() && flag == 'inactive') {
        placeHolderShimmer(limit);
        flag = 'active';
        start = start + limit;
        setTimeout(function() {
          getData(limit, start);
        }, 1000);
      }
    });
  });
</script>

<?php include_once('templates/header.php'); ?>

<h2>Load more data on page scroll using jQuery, Ajax and PHP</h2>

</div>

</div>

</section>

<?php include_once('templates/footer.php'); ?>

jQuery(document).ready(function() {

var limit = 5;

var start = 0;

var flag = "inactive";

function placeHolderShimmer(limit) {

var bindHTML = '';

for(var counter=0; counter<limit; counter++) {

bindHTML += '<div class="timeline-item">';

bindHTML += '<div class="animated-background">';

bindHTML += '<div class="background-masker header-top"></div>';

bindHTML += '<div class="background-masker header-left"></div>';

bindHTML += '<div class="background-masker header-right"></div>';

bindHTML += '<div class="background-masker header-bottom"></div>';

bindHTML += '<div class="background-masker subheader-left"></div>';

bindHTML += '<div class="background-masker subheader-right"></div>';

bindHTML += '<div class="background-masker subheader-bottom"></div>';

bindHTML += '<div class="background-masker content-top"></div>';

bindHTML += '<div class="background-masker content-first-end"></div>';

bindHTML += '<div class="background-masker content-second-line"></div>';

bindHTML += '<div class="background-masker content-second-end"></div>';

bindHTML += '<div class="background-masker content-third-line"></div>';

bindHTML += '<div class="background-masker content-third-end"></div>';

bindHTML += '</div>';

}

jQuery("#load-data-msg").html(bindHTML);

}

// call function

placeHolderShimmer(limit);

function getData(limit, start) {

jQuery.ajax({

url:"fetch_record.php",

method:"POST",

data:{limit:limit, start:start},

dataType: 'html',

cache: false,

success:function(html) {

if(html == '') {

jQuery('span#load-data-msg').html('<div class="text-muted" style="font-weight:bold; font-size:18px; text-align:center;">No more result yet!</div>');

flag = 'active';

} else {

jQuery('span#load-data').append(html);

jQuery('span#load-data-msg').html("");

flag = 'inactive';

}

})

}

if(flag == 'inactive') {

flag = 'active';

getData(limit, start);

}

jQuery(window).scroll(function() {

if(jQuery(window).scrollTop() + jQuery(window).height() > jQuery("span#load-data").height() && flag == 'inactive') {

placeHolderShimmer(limit);

flag = 'active';

start = start + limit;

setTimeout(function() {

getData(limit, start);

}, 1000);

}

});

</script>

Step 5: jQuery & Ajax Code:

We will also need to use jQuery code in index.php to load pagination and make Ajax request to load more records.

<script>
  jQuery(document).ready(function() {
    var limit = 5;
    var start = 0;
    var flag = "inactive";
    function placeHolderShimmer(limit) {
      var bindHTML = '';
      for(var counter=0; counter<limit; counter++) {
        bindHTML += '<div class="timeline-item">';
          bindHTML += '<div class="animated-background">';
            bindHTML += '<div class="background-masker header-top"></div>';
            bindHTML += '<div class="background-masker header-left"></div>';
            bindHTML += '<div class="background-masker header-right"></div>';
            bindHTML += '<div class="background-masker header-bottom"></div>';
            bindHTML += '<div class="background-masker subheader-left"></div>';
            bindHTML += '<div class="background-masker subheader-right"></div>';
            bindHTML += '<div class="background-masker subheader-bottom"></div>';
            bindHTML += '<div class="background-masker content-top"></div>';
            bindHTML += '<div class="background-masker content-first-end"></div>';
            bindHTML += '<div class="background-masker content-second-line"></div>';
            bindHTML += '<div class="background-masker content-second-end"></div>';
            bindHTML += '<div class="background-masker content-third-line"></div>';
            bindHTML += '<div class="background-masker content-third-end"></div>';
          bindHTML += '</div>';
        bindHTML += '</div>';
      }
      jQuery("#load-data-msg").html(bindHTML);
    }
    // call function
    placeHolderShimmer(limit);
    function getData(limit, start) {
      jQuery.ajax({
        url:"fetch_record.php",
        method:"POST",
        data:{limit:limit, start:start},
        dataType: 'html',
        cache: false,
        success:function(html) {
          if(html == '')  {
            jQuery('span#load-data-msg').html('<div class="text-muted" style="font-weight:bold; font-size:18px; text-align:center;">No more result yet!</div>');
            flag = 'active';
          }  else {
            jQuery('span#load-data').append(html);
            jQuery('span#load-data-msg').html("");
            flag = 'inactive';
          }
        }
      })
    }
    if(flag == 'inactive') {
      flag = 'active';
      getData(limit, start);
    }
    jQuery(window).scroll(function() {
      if(jQuery(window).scrollTop() + jQuery(window).height() > jQuery("span#load-data").height() && flag == 'inactive') {
        placeHolderShimmer(limit);
        flag = 'active';
        start = start + limit;
        setTimeout(function() {
          getData(limit, start);
        }, 1000);
      }
    });
  });
</script>
