Question

I use

if(!empty($_POST['login'])){
}

for checking that login is file is filled, it work when I checking 1 variable, but not working when I use

if(!empty($_POST['login'],$_POST['password'] )){
}

how to check 2 variables, I see that isset() too support only 1 variable

Answer 1

Use a logical and operation (&&) along with two calls to empty(), like so:

if( !empty( $_POST['login']) && !empty( $_POST['password'])) {
    // $_POST['login'] and $_POST['password'] are both not empty
}
