the form data needn't to be send by using javascript

if php is available, it is the best method to evaluate forms. This is because some people have javascript disabled. If you use javascript, your form will not work in this case. Using php means the server does the work.Plus, php is very simple. Just a bunch of IF statements and you are done. All my forms are done in php and I don't even have to use a seperate file. Just need an IF (!submit) {display form} ELSE {validate form}
