What are the drawbacks of using form submissions for handling data record interactions in PHP applications?

One drawback of using form submissions for handling data record interactions in PHP applications is the lack of validation and sanitization, which can lead to security vulnerabilities such as SQL injection attacks. To mitigate this risk, it is important to validate and sanitize user input before processing it in the application. 

// Validate and sanitize user input before processing
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $name = filter_var($_POST["name"], FILTER_SANITIZE_STRING);
    $email = filter_var($_POST["email"], FILTER_SANITIZE_EMAIL);
    
    // Process the data record interactions
}
