What is the issue with the PHP script provided in the forum thread regarding form validation?

The issue with the PHP script provided in the forum thread regarding form validation is that it is not properly sanitizing user input, leaving it vulnerable to potential security risks such as SQL injection attacks. To solve this issue, you should use PHP's filter_input function to sanitize user input before processing it. 

// Sanitize and validate form input
$name = filter_input(INPUT_POST, 'name', FILTER_SANITIZE_STRING);
$email = filter_input(INPUT_POST, 'email', FILTER_SANITIZE_EMAIL);

// Check if required fields are not empty
if(empty($name) || empty($email)){
    // Handle error, display error message or redirect back to form
} else {
    // Process the form data
    // Additional validation and processing logic here
}
