Star Rating System Using PHP and Jquery with ajax

In this article, we are going to create add a star rating in php(Star Rating System Using PHP and Jquery with ajax). here We have considered a t-shirt as a product. When a customer buys a product that time adds the rating and comment to a product. so we will discuss about a 5 star rating system in php mysql.

Step1: Create the database and table.

Now, first, we create a database and create an item_rating table.

CREATE TABLE `item_rating` (
  `id` int(255) NOT NULL,
  `rate_number` varchar(255) NOT NULL,
  `title` varchar(255) NOT NULL,
  `comment` text NOT NULL,
  `created` datetime NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

CREATE TABLE `item_rating` (

`id` int(255) NOT NULL,

`rate_number` varchar(255) NOT NULL,

`title` varchar(255) NOT NULL,

`comment` text NOT NULL,

`created` datetime NOT NULL

) ENGINE=InnoDB DEFAULT CHARSET=latin1;

Step2: create the index.php file.

Second, we will the configuration of the database. after then we will create a rating system using the bootstrap. when we will select star on the click on the star. we will use ajax call to pass data after selecting a star, title, and comment. we will get rating data using the count_rate_data function.

<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "rating";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

$sql="SELECT SUM(rate_number) AS total_rate,count(id) as number_record FROM item_rating";
$result = mysqli_query($conn, $sql);
$data = mysqli_fetch_array($result);

function count_rate_data($rate_number)
{
    $servername = "localhost";
    $username = "root";
    $password = "";
    $dbname = "rating";

    // Create connection
    $conn = new mysqli($servername, $username, $password, $dbname);
    $sql="SELECT count(id) as number_record FROM item_rating where rate_number='".$rate_number."' ";
    $result = mysqli_query($conn, $sql);
    $data = mysqli_fetch_array($result);
    if(!empty($data['number_record']))
    {
        return $data['number_record'];
    }
    else{
        return '0';
    }

}
?>

    if (mysqli_query($conn, $sql) === TRUE) {
