PHP注册不向MySQL PDO发送数据

Question

我已经在我的localhost和我的VPS上测试了这个注册表单。我根本无法将数据发送到MySQL。寄存器类确认表单中的错误，并表示帐户已成功创建，但它从未将其插入数据库。

<?php

Answer 1

相当简单的修复！

在第103行，您试图执行一个语句而不绑定所有值（您忘记将值绑定到＆＃39;：Credits＆＃39;和＃39;：Active＆＃39;），所以我和＃39;已在第100行和第101行添加了2个新行，为您完成此操作。为了让这些线路正常工作，我必须在$userArr添加额外的元素（＆＃39;积分＆＃39;以及＆＃39;活跃＆＃39;），这是在第21和22行完成的。

这是经过修复和测试的代码，尽情享受;）

我会将代码保存在我的计算机上，如果您需要更多帮助，请告诉我们。）

PS：您使用MD5来散列密码，您应该使用类似PBKDF2的东西，但如果您想要简单的东西，SHA-512也可以。做这样的事......

$hashedPass = "";

for($i=0; $i<1024; $i++){ //It's good to iterate password hashes many times.
  $hashedPass = hash("sha512", $userArr['password']);
}

$objStatement->bindValue(':Password', $hashedPass);
