php - 我无法将输入字段中的数据发送到我的 MySQL 数据库

Question

我有一个小问题。我有一张登记表。它工作得几乎完美，我可以检查输入字段的值，我可以检查天气我们在数据库中是否有相同的用户名，但如果一切正常，我无法将数据发送到我的数据库。我以管理员/root身份使用它，所以我有权限。问题是什么？请帮忙!

<?php    
  // declaring variables from input fields
  $email = $_POST['email'];
  $username=$_POST['username'];
  $password=$_POST['password'];
  $password2=$_POST['password2'];


  function registration ($username, $email, $password) {
      //new user registering
      //return true or errormessage

      //connecting to database, YEAH IT WORKS!
      $connection = connecting_to_db();

      //checking unique of username and IT WORKS!
      $result = $connection->query("SELECT * FROM user WHERE username='".$username."'");

      if (!$result) {
        throw new Exception ('We couldnt query. Sorry.');
      }
      if ($result->num_rows>0) {
        throw new Exception ('We have already this username! Choose something else!');
      }
      // if it is OK send it to the DB AND THIS IS NOT WORKING :-(
      $result = $connection->query("INSERT INTO user VALUES'".$username."', shal('".$password."'), '".$email."')");

      // I get alwasy this way and get this message.
      if (!$result) {
        throw new Exception ('We couldnt save your datas in our database. Try it later!');
      }
      return true;
  }

?>

看起来您的插入查询中有 shal(letter L) 而不是 sha1(# one)。打印出查询结果，您应该会看到您的问题。
