php contact forms and post variable

    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.

    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.
