Ajax Live Database Search

We can create a simple live database search as well as feature utilizing the Ajax with PHP, where the simple search live_results_searchs will be some records displayed as we start typing some like character in search form input box.

In this POST we’re going to make a live search box that will search the students table and show the live_results_searchs data asynchronously. so, first of all we need to make this table.

Phase 1: Making the Database Table

CREATE TABLE students (
    id INT NOT NULL PRIMARY KEY AUTO_INCREMENT,
    name VARCHAR(50) NOT NULL
);

Phase 2: Making the Search Form

simple Create a PHP file named “search-form.php” and put the following some source code inside of it.

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Pakainfo.com - PHP Live MySQL Database Search</title>
<style type="text/css">
    body{
        font-family: Arail, sans-serif;
    }
    /*Devloped By Pakainfo.com Formatting search box */
    .live_searchBox{
        width: 300px;
        position: relative;
        display: inline-block;
        font-size: 14px;
    }
    .live_searchBox input[type="text"]{
        height: 32px;
        padding: 5px 10px;
        border: 1px solid #CCCCCC;
        font-size: 14px;
    }
    .live_results_search{
        position: absolute;        
        z-index: 999;
        top: 100%;
        left: 0;
    }
    .live_searchBox input[type="text"], .live_results_search{
        width: 100%;
        box-sizing: border-box;
    }
    /*Devloped By Pakainfo.com Formatting live_results_search items */
    .live_results_search p{
        margin: 0;
        padding: 7px 10px;
        border: 1px solid #CCCCCC;
        border-top: none;
        cursor: pointer;
    }
    .live_results_search p:hover{
        background: #f2f2f2;
    }
</style>
<script src="https://code.jquery.com/jquery-1.12.4.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
    $('.live_searchBox input[type="text"]').on("keyup input", function(){
        /* Get input value on change */
        var form_liveval = $(this).val();
        var live_results_searchDropdown = $(this).siblings(".live_results_search");
        if(form_liveval.length){
            $.get("backend-search.php", {query_string: form_liveval}).done(function(data){
                //Devloped By Pakainfo.com :  Display the returned data in browser
                live_results_searchDropdown.html(data);
            });
        } else{
            live_results_searchDropdown.empty();
        }
    });
    
    // Set search input value on click of live_results_search item
    $(document).on("click", ".live_results_search p", function(){
        $(this).parents(".live_searchBox").find('input[type="text"]').val($(this).text());
        $(this).parent(".live_results_search").empty();
    });
});
</script>
</head>
<body>
    <div class="live_searchBox">
        <input type="text" autocomplete="off" placeholder="Search country..." />
        <div class="live_results_search"></div>
    </div>
</body>
</html>

Phase 3: Processing Search Query in Backend

<?php
/* Attempt MySQL server connection. Assuming you are running MySQL
server with default setting (user 'root' with no password) */
$db_link = mysqli_connect("localhost", "root", "", "demo");
 
// Check connection
if($db_link === false){
    die("ERROR: db Could not connect. " . mysqli_connect_error());
}
 
if(isset($_REQUEST['query_string'])){
    //Devloped By Pakainfo.com Prepare a select statement
    $sql = "SELECT * FROM students WHERE name LIKE ?";
    
    if($stmt = mysqli_prepare($db_link, $sql)){
        //Devloped By Pakainfo.com Bind variables to the prepared statement as parameters
        mysqli_stmt_bind_param($stmt, "s", $param_query_string);
        
        //Devloped By Pakainfo.com Set parameters
        $param_query_string = $_REQUEST['query_string'] . '%';
        
        //Devloped By Pakainfo.com Attempt to execute the prepared statement
        if(mysqli_stmt_execute($stmt)){
            $live_results_search = mysqli_stmt_get_live_results_search($stmt);
            
            //Devloped By Pakainfo.com Check number of rows in the live_results_search set
            if(mysqli_num_rows($live_results_search) > 0){
                // Fetch live_results_search rows as an associative array
                while($row = mysqli_fetch_array($live_results_search, MYSQLI_ASSOC)){
                    echo "<p>" . $row["name"] . "</p>";
                }
            } else{
                echo "<p>No matches found</p>";
            }
        } else{
            echo "ERROR: sorry Could not able to execute $sql. " . mysqli_error($db_link);
        }
    }
     
    // Devloped By Pakainfo.com Close statement
    mysqli_stmt_close($stmt);
}
 
//Pakainfo.com close connection
mysqli_close($db_link);
?>
