What are the potential pitfalls of not properly handling empty form fields in PHP scripts?

If empty form fields are not properly handled in PHP scripts, it can lead to unexpected behavior or errors in the application. This can result in incomplete or incorrect data being processed, potentially compromising the functionality and security of the system. To solve this issue, you can check for empty form fields before processing the data and handle them accordingly, such as displaying an error message or setting default values. 

// Check if form field is empty before processing
if(empty($_POST['field_name'])) {
    // Handle empty form field, such as displaying an error message or setting a default value
} else {
    // Process the form data
}
