doing a var_dump($_POST['comments'];
returns string(0) ""
So the value of $comments in $comments = $_POST['comments']; SHOULD be equal
to 0 or "", right?
In which case when I do my original:
if (!empty($comments)) {
echo "Do Something";
}
It SHOULD just bypass that and continue with my code, but instead it gives
me the error, "Changed database context to Database."
