通过使用带有 PDO 的用户 ID 更新用户信息 [重复]

【发布时间】：2019-03-08 10:20:52
【问题描述】：

我正在尝试更新数据库中现有的用户信息，但无论我尝试什么都不会执行。

代码： 

public function updateUser()
{
    $this->userId = $_SESSION['user_id'];
    var_dump($this->userId);
    include "DBConnect.php";
    $updateUser = $conn->prepare("UPDATE `users` SET 
    `user_username`=:user_name,`user_password`=:user_password,
    `user_firstname`=:user_firstname,`user_middlename`=:user_middlename,
    `user_lastname`=:user_lastname,`user_country`=user_country,
    `user_city`=:user_city,`user_street`=:user_street,
    `user_housenumber`=:user_housenumber,`user_postalcode`=:user_postalcode
    ,`user_email`=:user_email,`user_phone`=:user_phone 
    WHERE `user_id` =:user_id");
    $updateUser->bindParam(':user_id', $_SESSION['user_id']);
    $updateUser->bindParam(':user_name', $this->userName);
    $updateUser->bindParam(':user_password', $this->userPassword);
    $updateUser->bindParam(':user_firstname', $this->userFirstName);
    $updateUser->bindParam(':user_middlename', $this->userMiddleName);
    $updateUser->bindParam(':user_lastname', $this->userLastName);
    $updateUser->bindParam(':user_country', $this->userCountry);
    $updateUser->bindParam(':user_city', $this->userCity);
    $updateUser->bindParam(':user_street', $this->userStreet);
    $updateUser->bindParam(':user_housenumber', $this->userHouseNumber);
    $updateUser->bindParam(':user_postalcode', $this->userPostalCode);
    $updateUser->bindParam(':user_email', $this->userEmail);
    $updateUser->bindParam(':user_phone', $this->userPhone);

    var_dump($this->userId);
    var_dump($this->userName);
    var_dump($this->userPassword);
    var_dump($this->userFirstName);
    var_dump($this->userMiddleName);
    var_dump($this->userLastName);
    var_dump($this->userCountry);
    var_dump($this->userCity);
    var_dump($this->userStreet);
    var_dump($this->userHouseNumber);
    var_dump($this->userPostalCode);
    var_dump($this->userEmail);
    var_dump($this->userPhone);

    $updateUser->execute();
}

完全错误： 

string(1) "9" string(1) "9" string(4) "test" string(4) "test" string(4) "test" string(4) "test" string(4) "test" string(4) "test" string(4) "test" string(4) "test" string(2) "21" string(4) "test" string(4) "test" string(8) "12345678"

【问题讨论】：

  • 错误很明显..查询中PDO名称变量的数量和你绑定bindParam()的不一样
  • 确实@Pupil 这个编辑将直接显示缺少的topicstarter .. Topicstarter SQL 是用来阅读的，将 SQL 写成没有良好格式的“oneliner”是 10 次麻烦中的 9 次.
  • 您在 ``user_country=user_country, 中缺少 :

【解决方案1】：

我找到了，你只是错过了一个冒号添加到user_country，试试这个

{
    $this->userId = $_SESSION['user_id'];
    var_dump($this->userId);
    include "DBConnect.php";
    $updateUser = $conn->prepare("UPDATE `users` SET 
    `user_username`=:user_name,`user_password`=:user_password,
    `user_firstname`=:user_firstname,`user_middlename`=:user_middlename,
    `user_lastname`=:user_lastname,`user_country`=:user_country,
    `user_city`=:user_city,`user_street`=:user_street,
    `user_housenumber`=:user_housenumber,`user_postalcode`=:user_postalcode
    ,`user_email`=:user_email,`user_phone`=:user_phone 
    WHERE `user_id` =:user_id");
    $updateUser->bindParam(':user_id', $_SESSION['user_id']);
    $updateUser->bindParam(':user_name', $this->userName);
    $updateUser->bindParam(':user_password', $this->userPassword);
    $updateUser->bindParam(':user_firstname', $this->userFirstName);
    $updateUser->bindParam(':user_middlename', $this->userMiddleName);
    $updateUser->bindParam(':user_lastname', $this->userLastName);
    $updateUser->bindParam(':user_country', $this->userCountry);
    $updateUser->bindParam(':user_city', $this->userCity);
    $updateUser->bindParam(':user_street', $this->userStreet);
    $updateUser->bindParam(':user_housenumber', $this->userHouseNumber);
    $updateUser->bindParam(':user_postalcode', $this->userPostalCode);
    $updateUser->bindParam(':user_email', $this->userEmail);
    $updateUser->bindParam(':user_phone', $this->userPhone);

    var_dump($this->userId);
    var_dump($this->userName);
    var_dump($this->userPassword);
    var_dump($this->userFirstName);
    var_dump($this->userMiddleName);
    var_dump($this->userLastName);
    var_dump($this->userCountry);
    var_dump($this->userCity);
    var_dump($this->userStreet);
    var_dump($this->userHouseNumber);
    var_dump($this->userPostalCode);
    var_dump($this->userEmail);
    var_dump($this->userPhone);

    $updateUser->execute();
}

    【解决方案2】：

    找线：

    user_lastname`=:user_lastname,`user_country`=user_country,

    替换为：

    user_lastname`=:user_lastname,`user_country`=:user_country,

    user_country 之前缺少的分号没有将其绑定到 SQL 查询。

      【解决方案3】：

      您的问题是 user_name 和 user_country 的拼写错误，并且会话可能尚未初始化。最后，您应该检查所有变量中的拼写、错字、冒号、逗号错误等。

      以下只是我从您的代码中发现的结果

      首先你有 

      `user_username`=:user_name,

      而不是

      `user_name`=:user_name,

      其次

      你有（这里缺少冒号）

       `user_country`=user_country,

      而不是

       `user_country`=:user_country,

      第三次 user_id 是基于会话的，我没有看到您在代码中初始化会话的位置

      session_start();

      试试这个代码

      public function updateUser()
{
session_start();
    $this->userId = $_SESSION['user_id'];
    var_dump($this->userId);
    include "DBConnect.php";

    $updateUser = $conn->prepare("UPDATE `users` SET 
    `user_name`=:user_name,
    `user_password`=:user_password,
    `user_firstname`=:user_firstname,
    `user_middlename`=:user_middlename,
    `user_lastname`=:user_lastname,
    `user_country`=:user_country,
    `user_city`=:user_city,
    `user_street`=:user_street,
    `user_housenumber`=:user_housenumber,
    `user_postalcode`=:user_postalcode
    ,`user_email`=:user_email,
    `user_phone`=:user_phone WHERE `user_id` =:user_id");

    $updateUser->bindParam(':user_id', $_SESSION['user_id']);
    $updateUser->bindParam(':user_name', $this->userName);
    $updateUser->bindParam(':user_password', $this->userPassword);
    $updateUser->bindParam(':user_firstname', $this->userFirstName);
    $updateUser->bindParam(':user_middlename', $this->userMiddleName);
    $updateUser->bindParam(':user_lastname', $this->userLastName);
    $updateUser->bindParam(':user_country', $this->userCountry);
    $updateUser->bindParam(':user_city', $this->userCity);
    $updateUser->bindParam(':user_street', $this->userStreet);
    $updateUser->bindParam(':user_housenumber', $this->userHouseNumber);
    $updateUser->bindParam(':user_postalcode', $this->userPostalCode);
    $updateUser->bindParam(':user_email', $this->userEmail);
    $updateUser->bindParam(':user_phone', $this->userPhone);

    var_dump($this->userId);
    var_dump($this->userName);
    var_dump($this->userPassword);
    var_dump($this->userFirstName);
    var_dump($this->userMiddleName);
    var_dump($this->userLastName);
    var_dump($this->userCountry);
    var_dump($this->userCity);
    var_dump($this->userStreet);
    var_dump($this->userHouseNumber);
    var_dump($this->userPostalCode);
    var_dump($this->userEmail);
    var_dump($this->userPhone);

    $updateUser->execute();
}

      或者。

      而不是使用所有这个绑定绑定绑定...... 你可以使用数组方法。如果还有其他问题，请告诉我

      public function updateUser()
{

//initialized session if you have not done so
session_start();
    $this->userId = $_SESSION['user_id'];
    var_dump($this->userId);
    include "DBConnect.php";


$updateUser = $conn->prepare("UPDATE `users` SET 
    `user_name`=:user_name,
    `user_password`=:user_password,
    `user_firstname`=:user_firstname,
    `user_middlename`=:user_middlename,
    `user_lastname`=:user_lastname,
    `user_country`=:user_country,
    `user_city`=:user_city,
    `user_street`=:user_street,
    `user_housenumber`=:user_housenumber,
    `user_postalcode`=:user_postalcode
    ,`user_email`=:user_email,
    `user_phone`=:user_phone WHERE `user_id` =:user_id");




$updateUser->execute(array(
 ':user_id' =>  $_SESSION['user_id'],
 ':user_name' => $this->userName,
 ':user_password'=> $this->userPassword,
 ':user_firstname'=> $this->userFirstName, 
 ':user_middlename'=> $this->userMiddleName, 
 ':user_lastname'=> $this->userLastName, 
 ':user_country'=> $this->userCountry, 
 ':user_city'=> $this->userCity, 
 ':user_street'=> $this->userStreet, 
 ':user_housenumber'=> $this->userHouseNumber, 
 ':user_postalcode'=> $this->userPostalCode,  
 ':user_email'=> $this->userEmail, 
 ':user_phone'=> $this->userPhone,

));


}

      • 一个大的缺点是execute() 只能绑定为PDO::PARAM_STR，因此不理想地信任数据库以正确地自动转换数据..
