Thanks a bunch mate, sent you a gift. 😃

So then i could use return the same way for Email and Pwdmatch? Awesome help so far.

It does not have a definition, it did not use to require any since it is a super global. Did this change? Sorry i get confused at 2 with my dyslexia. localhost/signup.php?error=invalidUid <--- is what the brower says. <?php function emptyInputSignup($name,$email,$username,$pwd,$pwdRepeat) { $result; if (empty($name) || empty($email) || empty($username) || empty($pwd) || empty($pwdRepeat) ) { $result = true; } else { $result = false; } return $result; } function invalidUid($username) { $result; if (!preg_match("/^[a-zA-Z0-9]*$/", $username)) { $result = true; } else { $result = false; } } function invalidEmail($email) { $result; if (!filter_var($email, FILTER_VALIDATE_EMAIL)) { $result = true; } else { $result = false; } return $result; } function pwdMatch($pwd, $pwdRepeat) { $result; if ($pwd !== $pwdRepeat) { $result = true; } else { $result = false; } return $result; } function uidExists($conn, $username, $email) { $sql = "SELECT * FROM users WHERE usersUid = ? OR usersEmail = ?;"; $stmt = mysqli_stmt_init($conn); if (!mysqli_stmt_prepare($stmt, $sql)) { header("location: ../signup.php?error=stmtfailed"); exit(); } mysqli_stmt_bind_param($stmt, "ss", $username, $email); mysqli_stmt_execute($stmt); $resultData = mysqli_stmt_get_result($stmt); if ($row = mysqli_fetch_assoc($resultData)) { return $row; } else { $result = false; return $result; } mysqli_stmt_close($stmt); } function createUser($conn, $name, $email, $username, $pwd) { $sql = "INSERT INTO users (usersName, usersEmail, usersUid, usersPwd) VALUES (?,?,?,?);"; $stmt = mysqli_stmt_init($conn); if (!mysqli_stmt_prepare($stmt, $sql)) { header("location: ../signup.php?error=stmtfailed"); exit(); } $hashedPwd = password_hash($pwd, PASSWORD_DEFAULT); mysqli_stmt_bind_param($stmt, "ssss", $username, $email, $username, $hashedPwd); mysqli_stmt_execute($stmt); mysqli_stmt_close($stmt); header("location: ../signup.php?error=none"); exit(); } So do i need that statement or can i skip it or? 😛

So i have 2 errors and i have no real clue why, is it something php8 switched or is it Visual Studio? (I have the php extension) function invalidUid($username) { $result; if (!preg_match("/^[a-zA-Z0-9]*$/", $username)) { $result = true; } else { $result = false; } } The $result; gives and error "Use of unassigned variable '$result'" but it should not be needed to be assigned or? function uidExists($conn, $username, $email) { $sql = "SELECT * FROM users WHERE usersUid = ? OR usersEmail = ?;"; $stmt = mysqli_stmt_init($conn); if (!mysqli_stmt_prepare($stmt, $sql)) { header("location: ../signup.php?error=stmtfailed"); exit(); } mysqli_stmt_bind_param($stmt, "ss", $username, $email); mysqli_stmt_execute($stmt); $resultData = mysqli_stmt_get_result($stmt); if ($row = mysqli_fetch_assoc($resultData)) { return $row; } else { $result = false; return $result; } mysqli_stmt_close($stmt); } mysqli_stmt_close($stmt); Shows as an error why? this is the error message (Unreachable code detected) Thanks in advance i appriciate all help.
