$_post

[seby]

i'm using this to make an error message if a user post an empty form:

if ($_POST['go']) {
	if (empty($_POST['message'])) {
		echo "you didn't type anything";
	} 
} 

which works, but say they hit the space bar and hit submit, it still posts a blank result..

how can i fix this?

well, i fixed it, not sure if there is a better method..

if ($_POST['go']) {
	if (trim($_POST['message']) == '') {
		echo "you didn't type anything"; 
	} 
}
