I can check one field by saying: > > if ($field1) { > echo "Field 1 is not empty"; > } I'd use empty() since certain values would cause your if to evalute to false http://www.php.net/manual/en/function.empty.php if(!empty($field1){ > Can't I just say: > > if ($field1 and $field2 and $field3 and $field4) { > echo "All four fields are field in"; > } Have you tried it? Once again, I'd use empty() if(!empty($field1) && !empty($field2) !empty($field3) !empty($field4)){ I like '&&', rather than 'and', but that's just me. > if ($field1 or $field2 or $field3 or $field4) { > echo "At least one of the four fields is filled in"; > } See above but replace '&&' with '||' or 'or' > Maybe its not the word "and" and "or" but maybe its && or || > respectively? That's what I've seen in other languages that let you do > this. I'm sure there must be a way to do this with PHP, too. http://www.php.net/manual/en/language.operators.logical.php Tha manual is your friend, it can answer a lot of your questions. Once again, I don't see what this has to do with databases.
