php contact forms and post variable

Random

so i have www.test.com/file.php

in this file.php i have some variables which are name, address and email.

i call this file.php from an application which uses the server to send an email with various details.

i would like to prevent this file sending a blank email when i goto www.test.com/file.php without putting any variables in.

i have tried checking empty, "", etc on the post variables but i'm having no success.

can you recommend a way to check if a post variable is set or empty so that i can add in an if/else?

thanks

!isset
""
null

Maybe show us your code so we can see if you are doing something funny.

t1mm

if (isset($_POST['email']) && isset($_POST['name']) && isset($_POST['address'])){
     //send email
}
else {
      echo("One or more inputs were not supplied.");
}

Replace POST with GET depending on how the data is being sent.
