What potential issue can arise when specifying the file path in a PHP form action attribute?

When specifying the file path in a PHP form action attribute, the potential issue that can arise is that the file path may not be correctly specified, leading to errors in form submission or redirection. To solve this issue, it is recommended to use the `$_SERVER['PHP_SELF']` variable to dynamically generate the file path. 

<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
  <!-- Form fields go here -->
</form>
