I've been struggling to have a text form field required. So when some one doesn't fill his name he will receive an error like 'No title filled!'
I got this now but it doesn't work that well cause when I submit it insert into the db.
if(isset($_POST['submit'])) {
$update = "UPDATE post SET `title`='$_POST[title]', `pic`='$_POST[pic]', `youtube`='$_POST[youtube]' WHERE id = $_POST[id]";
$db->query($update) or die($db->error);
if($_POST['title'] == "") {
$error = "Title is required!";
}
if ($_POST['pic'] == "") {
$error = "Picture is required!";
}
if(isset($error)){
echo $error;
} else {
echo '<p>Your post has been updated!</p>';
}
}
