		//here HTML Form to generate suggestion on keyup
		$('#searchquery').keyup(function(e){
			e.preventDefault();
			var form = $('#pakainfoFrm').serialize();
			$.ajax({
				type: 'POST',
				url: 'get_membersList.php',
				data: form,
				dataType: 'json',
				success: function(response){
					if(response.error){
						$('#pakainfo_find').hide();
					}
					else{
						$('#pakainfo_find').show().html(response.data);
					}
				}
			});
		});
		//jQuery fill the input
		$(document).on('click', '.list-span3-list', function(e){
			e.preventDefault();
			$('#pakainfo_find').hide();
			var memberFname = $(this).data('memberFname');
			$('#searchquery').val(memberFname);
		});
	});
</script>
</body>
</html>

Step 3: Create get_membersList.php file

<?php
	if(isset($_POST['searchquery'])){
		$conn = new mysqli('localhost', 'root', 'root', 'atmiya_25');
		$datar_response = array('error' => false, 'data' => '');
 
		$searchquery = $_POST['searchquery'];
 
		if(empty($searchquery)){
			$datar_response['error'] = true;
		}else{
			$sql = "SELECT * FROM members WHERE name LIKE '%$searchquery%'";
			$sqlquery = $conn->query($sql);
 
			if($sqlquery->num_rows > 0){
				while($memberData = $sqlquery->fetch_assoc()){
					$datar_response['data'] .= "
						<li class='list-span3-list' data-memberFname='".$memberData['name']." ".$memberData['lastname']."'>".$memberData['name']." ".$memberData['lastname']."</li>
					";
				}
			}
			else{
				$datar_response['data'] = "
					<li class='list-span3-list'>No Any found data matches Members Records</li>
				";
			}
		}
 
		echo json_encode($datar_response);
	}
?>
