Lets see the complete example to create live ajax search box.

First Create "Post" Database Table
  `POSTID` int(3) NOT NULL,
  `POSTTITLE` varchar(100) NOT NULL,
  `POSTDETAILS` varchar(10000) NOT NULL,
  `POSTLINK` varchar(100) NOT NULL

Once You have created above table, Then put the records in this table.

Consists of database configuration details to establish database connection.
define('DB_SERVER', 'localhost');
define('DB_DATABASE', 'skptricksdemo');
define('DB_USERNAME', 'root');
define('DB_PASSWORD', '');


Controller work is to control the flow of execution. Here when user click on search button, JQuery script send request to "controller.php" page and it will process the request and return response to be displayed.
 $searchVal = trim($_POST["search-data"]);
 $dao = new DAO();
 echo $dao->searchData($searchVal);


This DAO class helps to establish the database connection and populate/fetch the records from MySQL database on AJAX call using JQuery.
class DAO{
 public function dbConnect(){
  $dbhost = DB_SERVER; // set the hostname
  $dbname = DB_DATABASE ; // set the database name
  $dbuser = DB_USERNAME ; // set the mysql username
  $dbpass = DB_PASSWORD;  // set the mysql password

  try {
   $dbConnection = new PDO("mysql:host=$dbhost;dbname=$dbname", $dbuser, $dbpass); 
   $dbConnection->exec("set names utf8");
   $dbConnection->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
   return $dbConnection;

  catch (PDOException $e) {
   echo 'Connection failed: ' . $e->getMessage();
 public function searchData($searchVal){
  try {
   $dbConnection = $this->dbConnect();
   $stmt = $dbConnection->prepare("SELECT * FROM `post` WHERE `POSTTITLE` like :searchVal");
   $val = "%$searchVal%"; 
   $stmt->bindParam(':searchVal', $val , PDO::PARAM_STR);   

   $Count = $stmt->rowCount(); 
   //echo " Total Records Count : $Count .<br>" ;
   $result ="" ;
   if ($Count  > 0){
    while($data=$stmt->fetch(PDO::FETCH_ASSOC)) {          
       $result = $result .'<div class="search-result"><a style="text-decoration:none;" href="'.$data['POSTLINK'].'">'.$data['POSTTITLE'].'</a> </div>';    

    return $result ;

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


This page consists of Jquery, AJAX, PHP and HTML code, which helps to fetch records form MySQL database when user enter any text in search box and click on search box.

  1. JQuery script helps to detect entered text in search box, when user click on search box.
  2. AJAX Code helps to fetch records from database and display the result in "search.php" page without page refresh.

<script src="jquery-3.2.1.min.js"></script>
 padding: 10px;
 border: solid 1px #BDC7D8; 
 margin-bottom: 20px; 
 display: inline;
 width: 80%;
 border-bottom:solid 1px #BDC7D8;
 font-family:Times New Roman;
 font-size: 20px;color:blue; 

// on click search results...
$(document).on("click", "#display-button" , function() { 
     var value = $("#search-data").val(); 
  if (value.length != 0) {
    } else {     

// This function helps to send the request to retrieve data from mysql database...
function searchData(val){
 $('#search-result-container').html('<div><img src="preloader.gif" width="50px;" height="50px"> <span style="font-size: 20px;">Please Wait...</span></div>');
 $.post('controller.php',{'search-data': val}, function(data){
  if(data != "")
  $('#search-result-container').html("<div class='search-result'>No Result Found...</div>");
 }).fail(function(xhr, ajaxOptions, thrownError) { //any errors?
 alert(thrownError); //alert with HTTP error

<div style="width: 700px;margin:40px auto;">

<div id="search-box-container" >
<label > How To Integrate Live Search In PHP And MySQL With JQuery : </label><br><br>
<input  type="text" id="search-data" name="searchData" placeholder="Search By Post Title (word length should be greater than 3) ..." autocomplete="off" />
<div id="display-button" style="">  <img style="padding:7px;" src="search.png"  />  </div>
