PDO INSERT INTO не работает

Question

Я пытаюсь вставить новую запись в MySQL Db, но подготовленный метод выражения, который я использую, не работает. Я использую запрос, который нашел here, и похоже, что он должен работать отлично, но это не так. У меня нет ошибок.

Вот моя форма:

<form name="registration" action="su-sql.php" method="post"> 
    <ul> 

     <fieldset> 
      <li><label for="email">Email</label></li> 
      <li><input type="email" name="email" id="email" required="required" aria-required="true" spellcheck="false" onblur="checkEmail(this.value);" onchange="checkEmail(this.value);"/></li> 
      <li><label for="password">Password</label></li> 
      <li><input type="password" name="password" id="password" required="required" aria-required="true" spellcheck="false" onblur="checkPassword(this.value);" onchange="checkPassword(this.value);"/></li> 
      <li><label for="passconfirm">Confirm Password</label></li> 
      <li><input type="password" name="passconfirm" id="passconfirm" required="required" aria-required="true" spellcheck="false" onblur="checkPassconfirm(this.value);" onchange="checkPassconfirm(this.value);"/></li> 
     </fieldset> 

     <fieldset> 
      <li><label for="firstname">First Name</label></li> 
      <li><input type="text" name="firstname" id="firstname" required="required" aria-required="true" onblur="checkFirstname(this.value);" onchange="checkFirstname(this.value);"/></li> 
      <li><label for="lastname">Last Name</label></li> 
      <li><input type="text" name="lastname" id="lastname" required="required" aria-required="true" onblur="checkLastname(this.value);" onchange="checkLastname(this.value);"/></li> 
      <li><label for="country">Country</label></li> 
      <li> 
       <select name="country" id="country" required="required" aria-required="true" onblur="checkCountry(this.value);" onchange="checkCountry(this.value);"> 
        <option selected value="" class="option" id="choose">Choose your Country</option>

        } 

        ?> 

       </select> 
       <div class="clear"></div> 
      </li>   
      <li><label for="gender">Gender</label></li> 
      <li> 
       <input checked type="radio" name="gender" value="male" required="required" aria-required="true" onchange="checkGender(this.value);"> Male 
       <input type="radio" name="gender" value="female" required="required" aria-required="true" onchange="checkGender(this.value);"> Female 
      </li> 
      <li><input type="submit" value="Submit"/></li>  
     </fieldset> 

    </ul> 
    <div class="clear"></div> 
</form> 

А вот PHP:

error_reporting(E_ALL); 
ini_set('display_errors',1); 



$db_host = "localhost"; 
$db_user = "user"; 
$db_pass = "pass"; 
$db_name = "name"; 


$db = new PDO('mysql:host='.$db_host.';dbname='.$db_name, $db_user, $db_pass); 


do { 

    /* 
     Generate random number between min and max 
     min: 1000000000 
     max: 2147483647 
    */ 

    $uid = mt_rand(1000000001,2147483646); 

    // make sure that uid isn't already being used 

    $query = $db->prepare("SELECT * FROM `members` WHERE `uid` = :uid"); 
    $query->bindValue(":uid", $uid); 
    $query->execute(); 

    $user = $query->fetch(PDO::FETCH_ASSOC); 

} while ($user['uid'] === $uid); 




$fbid = null; 
$email = $_POST['email']; 
$password = $_POST['password']; 
$firstname = $_POST['firstname']; 
$lastname = $_POST['lastname']; 
$country = $_POST['country']; 
$gender = $_POST['gender']; 


echo $firstname.' '.$lastname.': '.$uid; 


// Using prepared statements almost eliminates the possibility of SQL Injection. 

$query = $db->prepare("INSERT INTO `members`(uid, fbid, email, password, firstname, lastname, country, gender) 
    VALUES(:uid, :fbid, :email, :password, :firstname, :lastname, :country, :gender)"); 

$query->execute(array(
    "uid" => $uid, 
    "fbid" => $fbid, 
    "email" => $email, 
    "password" => $password, 
    "firstname" => $firstname, 
    "lastname" => $lastname, 
    "country" => $country, 
    "gender" => $gender 
)); 


// get the user's DB entry 

$query = $db->prepare("SELECT * FROM `members` WHERE `uid` = :uid"); 
$query->bindValue(":uid", $uid); 
$query->execute(); 

// Retrieve the results from the database 
$user = $query->fetch(PDO::FETCH_ASSOC); 

if($user) { 
    echo '<br/>'.$user['firstname'].' '.$user['lastname'].': '.$user['uid']; 
} else { 
    echo '<br/>No User'; 
} 

При загрузке страницы, она показывает имя и фамилию пользователя и их вновь сгенерированный номер ID все на первая линия. Во второй строке указано «Нет пользователя».

Пожалуйста, не забывайте, что пароль не защищен. Я просто делаю это.

Может ли кто-нибудь увидеть, где проблема?

Answer 1

Как @ предложил Фред-ии, я добавил следующую строку после подключения к БД:

$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

Когда я сделал это, я получил следующее сообщение об ошибке:

Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'fbid' cannot be null' in /home/ourfilmclub/public_html/build/su-sql.php:68 Stack trace: #0 /home/ourfilmclub/public_html/build/su-sql.php(68): PDOStatement->execute(Array) #1 {main} thrown in /home/ourfilmclub/public_html/build/su-sql.php on line 68 

В основном, колонка fbid не может быть null. Я заменяю null на '', и теперь все работает чудесно. Kudos @ Fred-ii-
