Hi, i use this code to check if both fields of form are filled in:

   if (!isset($_POST['userName'])){
       echo "Username is not filled in";
       exit();
    } 
    
    if (!isset($_POST['email'])){
       echo "E-mail is not filled in";
       exit();
    } 

However, this code does not print anything when the fields are left empty. No errors are displayed also. Any help, please?

According to the manual entry in php for isset, it determines if a variable is set and not null. An empty string "" is not null so it passes that check.

I think what you want is the empty function

You would benefit from creating your own functions to verify if the email or user name is set, and not empty. I believe there is an is_email or similar function to do this for you, feel free to look in the manual.
