PHP and Vue development: How to transfer and receive membership points

Introduction:
In many websites and applications, membership points are often used Reward users for their loyalty and engagement. In order to increase user participation in the platform, people sometimes need to implement the transfer and reception functions of member points. This article will introduce how to use PHP and Vue development to realize the transfer and reception functions of member points, and provide specific code examples.

Part One: Technical Requirements and Preparation
Before starting development, we need to ensure the following points:

1. You already have basic PHP and Vue development knowledge.
2. The local environment has already installed the relevant tools and frameworks required for PHP and Vue development, such as PHP interpreter, Vue CLI, etc.
3. You already have a PHP development environment that supports database operations, such as MySQL.

Part 2: Database Design and Creation
Before we start writing code, we need to design the database and create the corresponding table structure. For the transfer and reception functions of member points, we need to create the following two tables:

1. Member table (members): used to store basic information of members, such as member ID, name, etc.
2. Points table (points): used to store members’ points information, including point ID, member ID, point amount, etc.

You can use the following SQL statements to create these two tables:

--Create member table
CREATE TABLE members (
id INT(11) NOT NULL AUTO_INCREMENT,
name VARCHAR(50) NOT NULL,
PRIMARY KEY (id)
);

--Create points table
CREATE TABLE points (
id INT( 11) NOT NULL AUTO_INCREMENT,
member_id INT(11) NOT NULL,
amount INT(11) NOT NULL,
PRIMARY KEY (id),
FOREIGN KEY (member_id) REFERENCES members(id)
);

Part 3: PHP backend implementation
In terms of PHP backend implementation, we need to write interfaces to handle the transfer and reception functions of member points. The following is an example PHP code:

// Connect to the database
$servername = "localhost";
$username = "your_username";
$password = "your_password";
$dbname = "your_dbname";

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

// Process points Transfer request
if ($_SERVER['REQUEST_METHOD'] === 'POST' && $_POST['action'] === 'transfer') {
$sender = $_POST['sender'];
$receiver = $_POST['receiver'];
$amount = $_POST['amount'];

// Check if the sender has enough points
$check_sender_points = "SELECT amount FROM points WHERE member_id = $sender";
$sender_points_result = $conn->query($check_sender_points);
$sender_points = $sender_points_result->fetch_assoc()['amount'];

if ($sender_points

echo json_encode(['success' => false, 'message' => '您的账户积分不足']);
exit;

}

// Transfer points
$transfer_points = "UPDATE points SET amount = amount - $amount WHERE member_id = $sender";
$conn->query($transfer_points);

$receive_points = "UPDATE points SET amount = amount $amount WHERE member_id = $receiver";
$conn ->query($receive_points);

echo json_encode(['success' => true, 'message' => 'Points transfer successful']);
}

// Process points query request
if ($_SERVER['REQUEST_METHOD'] === 'GET' && $_GET['action'] === 'getPoints') {
$member_id = $_GET[ 'member_id'];

//Query the amount of points
$get_points = "SELECT amount FROM points WHERE member_id = $member_id";
$points_result = $conn->query($get_points) ;
$points = $points_result->fetch_assoc()['amount'];

echo json_encode(['points' => $points]);
}

$conn->close();
?>

Part 4: Vue front-end implementation
In terms of Vue front-end implementation, we need to write components to handle the transfer and transfer of member points. receive function. The following is an example Vue component:

<script><br>export default {<br> data() {</script>

return {
  sender: '',
  receiver: '',
  amount: 0,
  points: null
}

},
methods: {

transferPoints() {
  const formData = new FormData();
  formData.append('action', 'transfer');
  formData.append('sender', this.sender);
  formData.append('receiver', this.receiver);
  formData.append('amount', this.amount);

  fetch('/api.php', {
    method: 'POST',
    body: formData
  })
  .then(response => response.json())
  .then(result => {
    alert(result.message);
  });
},
getPoints() {
  const formData = new FormData();
  formData.append('action', 'getPoints');
  formData.append('member_id', this.sender);

  fetch(`/api.php?${new URLSearchParams(formData).toString()}`)
  .then(response => response.json())
  .then(result => {
    this.points = result.points;
  });
}

}
}

Part 5: Summary and Outlook
Through the above code examples, we have implemented the transfer and reception functions of member points. Of course, this is just a simple example. You can modify and expand it according to your own needs, such as adding security verification, permission control, etc.

I hope this article will be helpful to you and enable you to implement the transfer and reception functions of member points in your PHP and Vue development. Good luck with your development!
