You can use different names, different values, or both. Using different names are better for i18n (internationalization) than using different values for the distinction (as you don't need to modify the server-side script then even though the button caption changes according to the user language). However, the point here was to use code that was as similar to the original one as possible.

Yes, as can be read under "successful controls" in the HTML 4.01 Specification. > Your form prevents normal submission with : > | <form onsubmit="return false;" > > . > > The INPUT button being clicked is a separate event. The INPUT button's `click' event is irrelevant here. The problem is that calling the form's submit method does not make any button a successful control. >>> When I look at the posted values, I do not have a value for the >>> button. >>> How can I tell which of these buttons the user pressed? >> >> By RTFM and not shooting yourself in the foot: > > Link?

If I use input type="submit", the form always gets posted with a return keypress. -- Neil Aggarwal, (281)846-8957 FREE trial: cPanel VPS with unmetered bandwidth http://UnmeteredVPS.net/cpanel
