Very simple problem, but I feel this should have an easier answer than implementing reams of Javascript rubbish into my neat little PHP script. Basically I have a search form consisting of one text input and a submit button which, if you press the Enter key instead of actually clicking the button, loads up a blank search results page (the layout and stuff are there, just the search results are missing). I just don't understand why this should be the case for such a simple form. Has anyone got any idea what I might have done wrong?
