The sample software will automatically incorporate feedback for search skills. The ability to auto-suggest is retrieved from the server and listed below the text box as the user begins to type.


Create Database Table


A table must be created in the database to store data for autosuggestion. The following SQL produces a skill table in the MySQL database with some basic fields.


CREATE TABLE `skills` (


 `skill` varchar(100) COLLATE utf8_unicode_ci NOT NULL,

 `status` tinyint(1) NOT NULL DEFAULT '1' COMMENT '1=Active | 0=Inactive',


) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;


Autocomplete Search Input Field

In the input field a complete suggestion box with JQuery UI Plugin is connected to the code below.

jQuery UI Autocomplete Plugin:

Include the library files for jQuery and jQuery for Autocomplete use.

<!-- jQuery library -->

<script src=""></script>

<!-- jQuery UI library -->

<link rel="stylesheet" href="">

<script src=""></script>


Initialize Autocomplete:


Initialize the Autocomplete plugin by autocomplete().


  • Specify the input field element's selector ID/class (#Skill input) to add the Autocomplete feature.

  • To recover the auto-suggestions data, specify the local or remote source (search.php).



$(function() {


        source: "search.php",





HTML Input Element:


Initially, the skills are entered by a text field input.


  • In the autocomplete() method the ID of the input field should be defined.

  • The proposals are collected from the database and listed under the input box when the textbox is typed.

  • For the submission of the further form process the selected value is set to the input text field.



<input type="text" id="skill_input"/>


Fetch Autocomplete Data from Database with PHP and MySQL (search.php)


The autocomplete) (Autocomplete plugin is named for the search.php folder. This file recovers the search term skills data and returns them as a PHP-and MySQL-encoded JSON array.


A GET URL request is made by the autocomplete) (method and query string with the word field is inserted. Therefore, you can use PHP GET method to get the search term. Find the records in the MySQL database (skills table) and search them in $GET['term'] with the following PHP script. The filtered data returned as a JSON encrypted array to the autocomplete() process.



// Database configuration

$dbHost     = "localhost";

$dbUsername = "root";

$dbPassword = "root";

$dbName     = "codexworld";

// Create database connection

$db = new mysqli($dbHost, $dbUsername, $dbPassword, $dbName);

// Check connection

if ($db->connect_error) {

    die("Connection failed: " . $db->connect_error);


// Get search term

$searchTerm = $_GET['term'];

// Fetch matched data from the database

$query = $db->query("SELECT * FROM skills WHERE skill LIKE '%".$searchTerm."%' AND status = 1 ORDER BY skill ASC");

// Generate array with skills data

$skillData = array();

if($query->num_rows > 0){

    while($row = $query->fetch_assoc()){

        $data['id'] = $row['id'];

        $data['value'] = $row['skill'];

        array_push($skillData, $data);



// Return results as json encoded array

echo json_encode($skillData);



Replace Input Value with ID


The selected item value is sent for auto-complete entry on the server side when submitted to the form. You should replace the input field value with element ID if you want the selected value ID.


$(function() {


        source: "search.php",

        select: function( event, ui ) {







Autocomplete Widget Options

$( ".selector" ).autocomplete({

    source: [ "PHP", "Python", "Ruby", "JavaScript", "MySQL", "Oracle" ]



  • Remote source: The URL may be used to return JSON data from a remote source.

$( ".selector" ).autocomplete({

    source: ""
