What are the potential issues with using framesets in PHP for file uploads and database insertion?

Potential issues with using framesets in PHP for file uploads and database insertion include security vulnerabilities like cross-site scripting (XSS) attacks and potential for data manipulation. To solve this, it is recommended to use more secure methods like PHP's built-in functions for file uploads and database insertion, as well as implementing proper validation and sanitization techniques. 

// Example of secure file upload and database insertion without using framesets

// File upload handling
if(isset($_FILES['file'])) {
    $file_name = $_FILES['file']['name'];
    $file_tmp = $_FILES['file']['tmp_name'];
    move_uploaded_file($file_tmp, "uploads/" . $file_name);
}

// Database insertion
$connection = new mysqli("localhost", "username", "password", "database");
if($connection->connect_error) {
    die("Connection failed: " . $connection->connect_error);
}

$name = mysqli_real_escape_string($connection, $_POST['name']);
$email = mysqli_real_escape_string($connection, $_POST['email']);

$sql = "INSERT INTO users (name, email) VALUES ('$name', '$email')";
if($connection->query($sql) === TRUE) {
    echo "Record inserted successfully";
} else {
    echo "Error: " . $sql . "<br>" . $connection->error;
}

$connection->close();
