client code content display displayed e-mail ensure favorite funcionality generator html http implementing javascript key language number output page personal php programming return script scripting send serial server side summary throws try verify write

I made a script in a html page where a javascript code display the serial number but when i try to send to me an e-mail to verify the funcionality of that, instead of the serial number there is displayed the html code of the page. Why?

JavaScript is a client side programming language. When we can all code generator, we return as key whatever your http server throws at us .. and that will your page content. That's why you will need to write your code generator in server side scripting language and ensure that the only output we get is the code itself.

So i need a code generator in php?

PHP is one way (and my personal favorite) for implementing a code generator on the server side. So in summary, yes.
