} but when i run it as a form, it acts as though it is getting no input.

Is the form using METHOD=post to send data to the server?  Otherwise there
isn't any standard input.  The enviroment variable CONTENT_LENGTH should
tell how many bytes you can expect to read.

Try doing

	local input
	read -u0k $CONTENT_LENGTH input

This should stuff the entire stdin (up to $CONTENT_LENGTH bytes) into
the variable "input".  The input may be coming to you with "\r\n" line
endings, in which case I'm not sure how a plain "read" behaves.
