Question

我刚接到php，我需要一些帮助。我正在使用服务器端验证的注册表单，然后在验证后，表单输入应该提交到数据库。我输入数据，单击“提交”按钮，但数据未提交到数据库。没有错误消息。我希望你帮我指出哪里出错了，给我一个可能的解决方案。感谢。

Answer 1

我已经找到了问题并且问题已经解决了。第一个问题是Mysql数据库。 AutoIncrement colunm 正好未设置为AutoIncrement。因此，我打开PhpMyadmin来改变并将Id colunm设置为AutoIncrement。

第二个问题在于条件声明：

if($fullnameErr = $emailErr = $passwordErr = $conpasswordErr = $genderErr = $dobErr = $mobErr = $yobErr = "")

后来正常工作的正确代码行是：

if(empty($fullnameErr) && empty($emailErr) && empty($passwordErr) && empty($conpasswordErr) && empty($genderErr) && empty($dobErr) && empty($mobErr) && empty($yobErr))

对于那些在验证数据输入但不知道如何将数据保存到数据库表后感到困惑的人来说，这是一个重要的信息。
