Question

编辑到我之前的编辑：

所以我认为更改isset（）会起作用，但我的表单仍无效。我不知道为什么......

编辑：

我发现了我的错误。 isset（$ _ POST ['password_repeatr']）应该是isset（$ _ POST ['repeat_passwordr']）。

好的，所以我想创建一个简单的调度网站。我想尝试将OOP用于此程序。所以这个注册方面不起作用，基本上只刷新页面。什么都没有放入SQL数据库，甚至没有设置'user_id'会话。我也没有错。我将复制并粘贴代码。最重要的文件是register.php和scheduleApp.class.php。

的index.php：

Answer 1

很少有建议：

如果注册成功，您已添加代码，但没有错误处理。
如果您将表单提交到同一文件，则表单方法应保持空白。
该按钮应具有提交类型。

更改

<button id="register_submit">Register</button>

到

<button id="register_submit" type="submit">Register</button>

此外，无需触发2个查询，检查是否存在用户名或电子邮件。

为两者添加或条件。

所以，你的SQL应该是：

$query = "SELECT username FROM users WHERE username='".$this->mysqli->real_escape_string($username)."' OR email='".$this->mysqli->real_escape_string($email)."'

请尝试所有这些，并告诉我您的注册表格有效。

使用PHP和MYSQLI
