Is it possible to split the Username or Email already exists
into specific error messages?
I'm working on this user registration script, if you have any tips about the rest of code given would be much appreciated
if(isset($_POST['register'])){
if(
// check if posts not empty
empty($_POST['username']) ||
empty($_POST['email']) ||
empty($_POST['password']) ||
empty($_POST['re_password']) ||
$_POST['password'] != $_POST['re_password']
){
// if a field is empty, or the passwords don't match make a message
error = '<p>';
if(empty($_POST['username'])){
$error .= 'No username given<br>';
}
if(empty($_POST['email'])){
$error .= 'No email given<br>';
}
if(empty($_POST['password'])){
$error .= 'No password given<br>';
}
if(empty($_POST['re_password'])){
$error .= 'You must re-type your password<br>';
}
if($_POST['password'] != $_POST['re_password']){
$error .= 'Passwords don\'t match<br>';
}
$error .= '</p>';
}
else{
$username = $_POST['username'];
$email = $_POST['email'];
$password = $_POST['password'];
$password = $_POST['re_password'];
$query = mysqli_query(
$conn,"SELECT * FROM members WHERE username = '". $username ."' OR email = '". $email ."'");
if(mysqli_num_rows($query) > 0){
echo "Username or Email already exist";
}
else {
$sql = "INSERT INTO members (username, password, email)
VALUES
('$_POST[username]',
'$_POST[email]',
'$_POST[password]')";
if (mysqli_query($conn, $sql)) {
echo "Registered";
} else {
echo "Error: " . $sql . "<br>" . mysqli_error($conn);
}
}
}
}
if(isset($error)){
echo $error;
unset($error);
}
