[UnknownPlayer]

I made a form, like guestbook, and i dont wonna to write in mysql if in comment is just 1 or more spaces, no letters or numbers or chars, just space, how can i fix that?

You need to validate the form fields.

 

$comment = trim($_POST['comment']);
if( strlen($comment) < 5 ) { // or however many characters you want as a minimum
     // echo or store error message
} else {
     // proceed
}
