emty variable ?

[developer]

Hello!

How can I please check if a variable (which I have taken from a user input form) is emty or not?

(This is on the page after the form so I would prefer PHP and not java script)

(I will later use the variable in a "if-query" )

Thanks,

[lazzy]

thats an easy one 🆒 Just use the function empty() like this:

if(empty($username)) {
  echo "Hey, you forgot your name!";
  exit;
}
