Have you written any php code? That's what we are here to help with, and since you haven't shown us any php code there's nothing for us to help you with.

The only php logic/code you are showing us is the part that checks for the existence of the 'txtName' field in your html input. Sure you are using a php echo command to store all the html code but I don't see a script that uses that variable (to output it to the client) nor do I see any code that even attempts to receive the input from your form and try to validate it.

 

How about making a stab at receiving the POST data and doing some reading and attempt to write proper handling code? Then ask for help making it correct.

As ginerjm mentioned, the PHP code shown is used to display the form. Do you have any code that processes the form submission? Basically, it would help to know where you're stuck? Which field(s) are you looking to validate? And what is considered valid?

 

If you're looking for help on the basics of form validation and/or processing form submissions, there are many resources online:
