What are common pitfalls in PHP form handling that can lead to issues like the form not submitting data properly?

One common pitfall in PHP form handling is not properly setting the form's method attribute to "POST" when submitting data. This can lead to issues where the form data is not being submitted correctly. To solve this issue, ensure that the form method is set to "POST" in the HTML form tag. 

<form method="POST" action="submit_form.php">
  <!-- form fields go here -->
</form>
