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){

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.

See above but replace '&&' with '||' or 'or'

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.
