What are the potential pitfalls of using frames in PHP to handle database functions and form submissions?

Using frames in PHP to handle database functions and form submissions can lead to security vulnerabilities such as cross-site scripting (XSS) attacks and data manipulation. It is recommended to use server-side validation and prepared statements to prevent these risks. 

// Example of using server-side validation and prepared statements to handle form submissions and database functions

// Validate form input
if(isset($_POST['submit'])){
    // Sanitize input data
    $input = filter_input_array(INPUT_POST, FILTER_SANITIZE_STRING);

    // Validate input data
    if(!empty($input['name']) && !empty($input['email'])){
        // Prepare SQL statement
        $stmt = $pdo->prepare("INSERT INTO users (name, email) VALUES (:name, :email)");

        // Bind parameters
        $stmt->bindParam(':name', $input['name']);
        $stmt->bindParam(':email', $input['email']);

        // Execute SQL statement
        $stmt->execute();

        // Redirect or display success message
        header('Location: success.php');
        exit();
    } else {
        // Display error message
        echo "Please fill out all fields.";
    }
}
