What potential pitfalls should be considered when trying to display availability information from a PayPal payment button on a product page?

One potential pitfall to consider when displaying availability information from a PayPal payment button on a product page is that the availability status may not always be up to date if the product inventory changes frequently. To address this, you can implement a dynamic solution that fetches real-time availability information from your database or e-commerce platform whenever the product page is loaded. 

// Example PHP code snippet to dynamically display availability information from a database

// Connect to your database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

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

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Query database for availability information
$product_id = $_GET['product_id']; // Assuming product_id is passed in the URL
$sql = "SELECT availability FROM products WHERE id = $product_id";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output availability information
    while($row = $result->fetch_assoc()) {
        echo "Availability: " . $row["availability"];
    }
} else {
    echo "Availability information not available.";
}

$conn->close();
