Also look at empty(). I don't know if the $_POST array will send the key if it as no variable. I know on a regular post it does send the variable, but it has no value. I have used isset with just receiving post data and got strange results. On one I had an isset statement that ran a result that bypassed some code. When is submitted the form I got results as if the isset was being executed and the code was skipped. Just to make sure this was the case, I added echo "hello"; on the first line of the isset bypass coding and after running the script I got the results without the bypass. I took the hello back out and it bypassed! So adding the hello statement affected whether isset gave a positive or negative response. The variable isset was checking in this case was not being sent with a value. I changed to empty() and got the result I was looking for. If $_POST sends the key but not a value when you submit the form without a value assigned to the variable then isset may not always work.
