登録がデータを挿入しない

Question

こんにちは、stackoverflowコミュニティ。 私は現在、小規模な学校プロジェクトを開発中です。 しかし、登録に問題があります。 データベースにデータを投稿していないようです。 原因を特定できません。私は手動でphpmyadminからデータを挿入できるので！ 私はむしろMYSQLとPHPになっています。 はい、PHPを使用してデータベースにmysql接続を作成しました。 その目的で問題はありません。

以下のコード：

<div class="errors-container"> 
<?php 
    if (isset($_POST['registerBtn'])) 
    { 
      $username = $_POST['username']; 
      $password = $_POST['passwd']; 
      $repeat = $_POST['rpasswd']; 
      $email = $_POST['email']; 
      $terms = $_POST['terms']; 
      $errors = array(); 
      if (empty($username) || empty($password) || empty($repeat) || empty($email)) 
      { 
       $errors[] = 'Please fill in all required fields.'; 
      } 
      $checkUsername = $odb -> prepare("SELECT * FROM `users` WHERE `username`= :username"); 
      $checkUsername -> execute(array(':username' => $username)); 
      $countUsername = $checkUsername -> rowCount(); 
      if ($countUsername != 0) 
      { 
      $errors[] = 'The username you have entered is already in use.'; 
      } 
      $checkEmail = $odb -> prepare("SELECT * FROM `users` WHERE `email`= :email"); 
      $checkEmail -> execute(array(':email' => $email)); 
      $countEmail = $checkEmail -> rowCount(); 
      if ($countEmail0 != 0) 
      { 
       $errors[] = 'The email you have entered is already in use.'; 
      } 
       if (strlen($_POST['passwd']) < 4) { 
       $errors[] = 'The username you have entered is too short.'; 
       } 
       if (strlen($_POST['username']) > 15) { 
       $errors[] = 'The username you have entered is too long.'; 
       } 
      if (!filter_var($email, FILTER_VALIDATE_EMAIL)) 
      { 
       $errors[] = 'You have entered an invalid e-mail address.'; 
      } 
      if (!ctype_alnum($username)) 
      { 
       $errors[] = 'The username you have entered is invalid.'; 
      } 
      if ($password != $repeat) 
      { 
       $errors[] = 'The passwords you have entered does not match.'; 
      } 
      if ($terms != 'agree') 
      { 
       $errors[] = 'You have to agree t.o.s before using our service.'; 
      } 
      if (empty($errors)) 
      { 
       $sha = hash("sha512", $password); 
       $activation = generateRandomString(); 
       $insertUser = $odb -> prepare("INSERT INTO `users` VALUES(NULL, :username, :password, :email, 0, 0, 0, 0, 0)"); 
       $insertUser -> execute(array(':username' => $username, ':password' => $sha, ':email' => $email)); 
       //Send mail here 

       echo '<div class="alert alert-success fade in"><button type="button" class="close close-sm" data-dismiss="alert"><i class="fa fa-times"></i></button><strong>Success!</strong> You have registered your account successfully!

      } 
      else

       foreach($errors as $error) 
       { 
        echo '- '.$error.'<br />'; 
       } 
       echo '</div>'; 
      } 
     } 
?> 
</div>

に問題があります：（！$ countEmail = 0）（！$ countEmail0 = 0）場合は、場合にそれを変更する必要があり、あなたの変数名に注意を払います、これは試してみるためにsmtgです：

$insertUser = $odb -> prepare("INSERT INTO `users` VALUES(NULL, :username, :password, :email, 0, 0, 0, 0, 0)"); 
$insertUser->bindParam(':username', $username); 
$insertUser->bindParam(':password', $password); 
$insertUser->bindParam(':email', $email); 
$insertUser->execute();
