In one of my php pages, I have a form that requires the user to click "Search
for Surname". If however they press "Enter", undesirable effects occur.
I've successfully trapped if an empty string is in the <input
type="text"....>, but "Enter" eludes my efforts to trap it for an appropriate
"Educational" message about following instructions :>
ie:
if ($sname == "") {echo "Please enter a Surname and click "Search for
Surname'.", exit;}
if (eregi(\r == true) {exit;} // something tells me this isn't correct!!
Any ideas how I can accomplish this -- the code is asking for search criteria
for a query into PostgreSQL (it's coded between <?php . . . ?>)
Any ideas, suggestions, or where to look would be appreciated.
Tia,
Andre
