PHP Live Mysql Database Search Example

Apr 29, 2021 . Admin

Hi Dev,

In this blog, you'll learn how to create a live MySQL database search feature using PHP and Ajax.

Ajax Live Database Search

You can create a simple live database search functionality utilizing the Ajax and PHP, where the search results will be displayed as you start typing some character in search input box.

In this tutorial we're going to create a live search box that will search the countries table and show the results asynchronously. But, first of all we require to create this table.

Step 1: Creating the Database Table

In this step you can create database `php_curd`.

Create `table_name` inside the database.

You can execute the following command to create the table columns to store the files in the database.

CREATE TABLE `product` (
  `id` int(11) UNSIGNED NOT NULL,
  `product_name` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
  `product_price` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
  `product_category` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
  `product_details` text COLLATE utf8mb4_unicode_ci NOT NULL,
  `product_stock` int(11) COLLATE utf8mb4_unicode_ci NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;
Step 2: Creating the Search Form

Now, let's create a simple web interface that allows user to live search the names of countries available in our countries table, just like an autocomplete or typeahead.

Create a PHP file named "search-form.php" and put the following code inside of it.

<!DOCTYPE html>
<html lang="en">
<meta charset="UTF-8">
<title>PHP Live MySQL Database Search -</title>
<link rel="stylesheet" href="">
        font-family: Arail, sans-serif;
    /* Formatting search box */
        width: 100%;
        position: relative;
        display: inline-block;
        font-size: 14px;
    .search-box input[type="text"]{
        height: 32px;
        padding: 5px 10px;
        border: 1px solid #CCCCCC;
        font-size: 14px;
        position: absolute;        
        z-index: 999;
        top: 100%;
        left: 0;
    .search-box input[type="text"], .result{
        width: 100%;
        box-sizing: border-box;
    /* Formatting result items */
    .result p{
        margin: 0;
        padding: 7px 10px;
        border: 1px solid #CCCCCC;
        border-top: none;
        cursor: pointer;
    .result p:hover{
        background: #f2f2f2;
<script src=""></script>
    $('.search-box input[type="text"]').on("keyup input", function(){
        /* Get input value on change */
        var inputVal = $(this).val();
        var resultDropdown = $(this).siblings(".result");
            $.get("backend-search.php", {term: inputVal}).done(function(data){
                // Display the returned data in browser
        } else{
    // Set search input value on click of result item
    $(document).on("click", ".result p", function(){
    <div class="container mt-5">
        <div class="row">
            <div class="col-md-12">
                <h1>PHP Live MySQL Database Search -</h1>
                <div class="search-box mx-auto d-block mt-4s">
                    <input type="text" class="form-control" autocomplete="off" placeholder="Search product_name..." />
                    <div class="result"></div>
Step 3: Processing Search Query in Backend

And here's the source code of our "backend-search.php" file which searches the database based on query string sent by the Ajax request and send the results back to browser.


    /* Attempt MySQL server connection. Assuming you are running MySQL
    server with default setting (user 'root' with no password) */
    $link = mysqli_connect("localhost", "root", "root", "php_curd");
    // Check connection
    if($link === false){
        die("ERROR: Could not connect. " . mysqli_connect_error());
        // Prepare a select statement
        $sql = "SELECT * FROM product WHERE product_name LIKE ?";
        if($stmt = mysqli_prepare($link, $sql)){
            // Bind variables to the prepared statement as parameters
            mysqli_stmt_bind_param($stmt, "s", $param_term);
            // Set parameters
            $param_term = $_REQUEST["term"] . '%';
            // Attempt to execute the prepared statement
                $result = mysqli_stmt_get_result($stmt);
                // Check number of rows in the result set
                if(mysqli_num_rows($result) > 0){
                    // Fetch result rows as an associative array
                    while($row = mysqli_fetch_array($result, MYSQLI_ASSOC)){
                        echo "

" . $row["product_name"] . "

"; } } else{ echo "

No matches found

"; } } else{ echo "ERROR: Could not able to execute $sql. " . mysqli_error($link); } } // Close statement mysqli_stmt_close($stmt); } // close connection mysqli_close($link); ?>

I Hope It will help you..
