This is a very simple script which has 2 files. One is an HTML (index.php) file with a Search input box and the second is a PHP (do_search.php) file that has a regular MySQL connect(db.php) and a select statement to get the data from database. This script also has a Loading message shown while the data is being pulled from MySQL. Please note that live search might use more resources from your server. It might result in server overload / slowness if your infrastructure is limited.

Step1 : Setup your database and table in MySQL
Before you run this script make sure you have created a database and table in MySQL. Below is the sample sql command to create a database, table, and insert some dummy rows.

--
-- Table structure for table `live_search`
--

CREATE TABLE `live_search` (
  `id` int(10) NOT NULL,
  `name` varchar(255) NOT NULL,
  `email` varchar(100) NOT NULL,
  `date` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
) ENGINE=MyISAM DEFAULT CHARSET=latin1;

--
-- Dumping data for table `live_search`
--

INSERT INTO `live_search` (`id`, `name`, `email`, `date`) VALUES
(1, 'Raja', 'Raja@developerdesks.com', '2016-08-29 05:34:36'),
(2, 'Ragav', 'Ragav@developerdesks.com', '2016-08-29 05:34:36'),
(3, 'Sangeet kumar', 'sangeet@developerdesks.com', '2016-08-29 05:35:31'),
(4, 'Tharun', 'Tharun@developerdesks.com', '2016-08-29 05:35:31'),
(5, 'Kabi', 'kabi@developerdesks.com', '2016-08-29 05:35:33');

-- Table structure for table `live_search`

CREATE TABLE `live_search` (

`id` int(10) NOT NULL,

`name` varchar(255) NOT NULL,

`email` varchar(100) NOT NULL,

`date` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP

) ENGINE=MyISAM DEFAULT CHARSET=latin1;

-- Dumping data for table `live_search`

INSERT INTO `live_search` (`id`, `name`, `email`, `date`) VALUES

(1, 'Raja', '[email protected]', '2016-08-29 05:34:36'),

(2, 'Ragav', '[email protected]', '2016-08-29 05:34:36'),

(3, 'Sangeet kumar', '[email protected]', '2016-08-29 05:35:31'),

(4, 'Tharun', '[email protected]', '2016-08-29 05:35:31'),

(5, 'Kabi', '[email protected]', '2016-08-29 05:35:33');

Step 2: Index page for search form.
Create the live form for searching.

<div class="container">
<h1>Live search using php and mysql using jquery</h1>
	<div class="row">
		<div class="panel panel-default">
			<div class="panel-heading">
				<span>Live Search</span>
			</div>
			<div class="form-group">
				<label for="username">Username :</label>
				<input name="keysearch" value="" placeholder="name" id="keysearch" type="text" class="form-control">
				<span id="loading">Loading...</span>
			</div>
			<div id="result"></div>
		</div>
	</div>
</div>

<h1>Live search using php and mysql using jquery</h1>

<span>Live Search</span>

</div>

<label for="username">Username :</label>

<span id="loading">Loading...</span>

</div>

</div>

Step 3: Creating a do search for getting data from database.
Create the mysql query for getting the data from table using “like” options.

<?php
include('db.php');
if(isset($_POST['keysearch']))
{
    $search = $_POST['keysearch'];
    $data = mysql_query("SELECT * FROM `live_search` WHERE `name` like '%$search%' order by id LIMIT 5");
    while($row = mysql_fetch_array($data))
    {
		if($data) {
        $username   = $row['name'];
        echo "<div class='show'><img src='' id='search' /><span class='name'> $username </span></div>";
    }
	else
	{ echo "No found results";}
}
}
?>

<?php

include('db.php');

if(isset($_POST['keysearch']))

{

$search = $_POST['keysearch'];

$data = mysql_query("SELECT * FROM `live_search` WHERE `name` like '%$search%' order by id LIMIT 5");

while($row = mysql_fetch_array($data))

{

if($data) {

$username = $row['name'];

echo "<div class='show'><img src='' id='search' /><span class='name'> $username </span></div>";

}

else

{ echo "No found results";}

}

Step 4: jquery code for get the search value and pass to do_seach page.
Using the jquery you can get the search word and pass to the next page using variable and post method.

<script>
$(document).ready(function(){
	var req = null;
	$('#keysearch').on('keyup', function(){
		var key = $('#keysearch').val();
		if (key && key.length > 2)
		{
			$('#loading').css('display', 'block');
			if (req)
				req.abort();
			req = $.ajax({
				url : 'do_search.php',
				type : 'POST',
				cache : false,
				data : {
					keysearch : key,
				},
				success : function(data)
				{
					console.log(data)
					if (data)
					{
						$('#loading').css('display', 'none');
						$("#result").html(data).show();
					}
				}
			});
		}
		else
		{
			$('#loading').css('display', 'none');
			$('#result').css('display', 'none');
		}
 
	});
});
</script>

$(document).ready(function(){

var req = null;

$('#keysearch').on('keyup', function(){

var key = $('#keysearch').val();

if (key && key.length > 2)

{

$('#loading').css('display', 'block');

if (req)

req.abort();

req = $.ajax({

url : 'do_search.php',

type : 'POST',

cache : false,

data : {

keysearch : key,

success : function(data)

{

console.log(data)

if (data)

{

$('#loading').css('display', 'none');

$("#result").html(data).show();

}

});

}

else

{

$('#loading').css('display', 'none');

$('#result').css('display', 'none');

}

});

</script>

Step 4: Add css code fro your design.

.panel-default{padding: 15px;}
.form-group{margin-top: 15px;}
.panel-heading{background-color: #40A2BE !important; color: #FFFFFF !important;}
#loading{display: none;}
#searchid
{
    width:500px;
    border:solid 1px #000;
    padding:10px;
    font-size:14px;
}
#result
{
    position:absolute;
    width:500px;
    padding:10px;
    display:none;
    margin-top:-1px;
    border-top:0px;
    overflow:hidden;
    border:1px #CCC solid;
    background-color: white;
}
.show{font-size:20px;height: 50px;padding: 5px;}
.show:hover{background:#40A2BE;color:#FFF;cursor:pointer;}
img#search{width:50px; height:40px; float:left; margin-right:6px;}

.panel-default{padding: 15px;}

.form-group{margin-top: 15px;}

.panel-heading{background-color: #40A2BE !important; color: #FFFFFF !important;}

#loading{display: none;}

#searchid

{

width:500px;

border:solid 1px #000;

padding:10px;

font-size:14px;

}

#result

{

position:absolute;

width:500px;

padding:10px;

display:none;

margin-top:-1px;

border-top:0px;

overflow:hidden;

border:1px #CCC solid;

background-color: white;

}

.show{font-size:20px;height: 50px;padding: 5px;}

.show:hover{background:#40A2BE;color:#FFF;cursor:pointer;}

img#search{width:50px; height:40px; float:left; margin-right:6px;}
