Tim, thanks for the tip. I had heard of this behavior before, but never
witnessed it. Today I wrote a test form with 1 text field and 1 submit, and
it did do this: when I submitted via return, the submit field was not
posted. However, when I added a second text field to the form, the submit
did get posted. I was careful that the focus was still in the text field,
and not on the button, when I hit return.
Any ideas on why this inconsistency? Just curious. Since it is inconsistent,
your point is important and well-taken.
My code is below if anyone wants to play.

It has to do with the HTML standard, which says that: If a form contains more than one submit button, only the activated submit button is successful. This appears on: http://www.w3.org/TR/html4/interact/forms.html#h-17.13 Note that the CGI standard really has little to do with PHP unless you compiled in CGI mode. Some behaviour was inherited from it, but really, all that is relevant to us is the HTML and the HTTP standards.

[PHP] RE: multiple submit buttons
As far as any CGI is concerned there is only one submit, The one that is pressed. The other one is simply not posted. But be careful using values of submit buttons ... if the user hits return instead of clicking one of the buttons you won't get anything. If you want a default value try a hidden field before the submits with same name.

Re: [PHP] RE: multiple submit buttons
Maybe it is not supported by CGI but that doesn't mean it is not supported by the browser. There is no reason for IE of course to say it hurts. When you click first button bth is Yes, click on second button bth is No. Also you can have several buttons everyone of them do submit with different names, so if one button is named edit, other - delete. When a user clicks delete button PHP put in $HTTP_GET_VARS or $HTTP_POST_VARS delete index. There is no edit index.
