Click and Enter not the same?

[deep]

Hello,

I have been working on a new site and noticed that if i use

if(isset($_POST['Submit'])){}

To submit my form and do whatever is needed the script will not run when I press Enter button...?? It only workd when I actually click the submit butten only?? can this be fixed?

Thanks!

There is a peculiar case where if you only have 1 input control other than the submit button, using enter does not submit the form.

If you increase the number of input controls, this problem vanishes.
