What is the potential issue with the form action URL in the PHP code provided?
The potential issue with the form action URL in the PHP code provided is that it is missing the file extension ".php". This could result in the form not submitting data to the correct PHP file for processing. To solve this issue, simply add the ".php" extension to the form action URL.
<form action="process_form.php" method="post">
<!-- form fields go here -->
<input type="submit" value="Submit">
</form>
