多重解析错误：PHP代码语法错误？

Question

嗨，每当我按下提交时，我的代码就会出现错误，该代码会链接到联系表格。当前是“解析错误：语法错误，意外的';'在第12行的/websitename/public_html/GloboGym/assets/includes/signup.inc.php中“”

当我尝试删除此意外的';'时有人可以帮助我吗？甚至除了前三行之外的所有代码都仍然会出错。

<?php
    if (isset($_POST['signup-submit'])) {

        require 'connect_db.php';

        $username = $_POST['uid'];
        $email = $_POST['mail'];
        $password = $_POST['pass'];
        $passwordRepeat = $_POST['pass-repeat'];

        if (empty($username) || (empty($email) || (empty($password) || (empty($passwordRepeat)) {
            header("Location: ../assets/signup.php?error=emptyfields&uid=".$username."&mail=".$email);
        }

    }

您应该关闭if函数，然后像这样编写空函数：

if (empty($username) || empty($email) || empty($password) || empty($passwordRepeat)) {
    //execute if statement
}
