Checking for empty fields

This is probly one of the simplier questions. What I need to do is check to make sure all of the fields are entered. I figured the best way for me to do this is to say "If the field is empty, $action eq 0, then the $action amount would determine the execution of the remaining script. Is their an %ENV variable that means null?

Also can I put multiple declarations in my if statement? (i.e.

if ($name eq "null, $address eq "null, ..etc
}

Can I do something like that?

Thanks for your help

I have asked the same question and have
detailed the answer that I received:

The following code should check to make sure that all fields ($name, $email, $pass) were submitted:

code:

if($name eq "" | | $email eq "" | | $pass eq "") { #the | | means 'or'
print "not all required fields were filled in!";
exit; #this will stop the script from continuing and registration processes, ect
}
#put registration or whatever you want next here

Hope that helped.

that it does not interfere with normal script operations (I guess?)
