What are common pitfalls when creating a contact form with required fields in PHP?

One common pitfall when creating a contact form with required fields in PHP is not properly validating the input data. To solve this issue, you should check if the required fields are filled out before processing the form submission. 

// Check if required fields are filled out
if(empty($_POST['name']) || empty($_POST['email']) || empty($_POST['message'])) {
    echo "Please fill out all required fields.";
} else {
    // Process form submission
    // Your code to handle the form data goes here
}
