Forms and PHP

Hello,

I have two forms on my website each will use the same code. However, I need the code to echo out an error when the user inputs invalid data. Should I duplicate this code across two HTML pages although it might seem bad practice? Or should I keep the code in a separate file, but how would I show the error message within the submitted web page?

Thanks for your help and support!

Generally the answer to "should I duplicate X" is going to be no. Without knowing the structure of your application the most basic solution is to create a smaller PHP file that checks whether the error(s) exist and spit out the error for the user and then <?php include(''); ?> that in each page. This means you now have one thing to maintain instead of 2 (until your page grows and 6 months later it's 20).

The same can be done to reuse the form since it sounds like the form is a duplicate as well.
