Php 通过使用带有PDO的用户id更新用户信息

php mysql

Php 通过使用带有PDO的用户id更新用户信息,php,mysql,pdo,Php,Mysql,Pdo,我正在尝试更新数据库中的现有用户信息，但无论我尝试什么，它都不会执行代码： public function updateUser() { $this->userId = $_SESSION['user_id']; var_dump($this->userId); include "DBConnect.php"; $updateUser = $conn->prepare("UPDATE `users` SET `user_usernam

user\u country

前面缺少的分号未将其绑定到SQL查询。

替换为：

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

user\u country

之前缺少的分号未将其绑定到SQL查询。

您的问题是用户名和user\u country的键入错误，会话可能尚未初始化。最后，您应该检查所有变量的拼写、打字、冒号、逗号错误等

下面是我从您的代码中得到的发现

session_start();

首先，你有

public function updateUser()

    var_dump($this->userId);

`user_username`=:user_name,

您有（此处缺少冒号）

而不是

`user_name`=:user_name,

 `user_country`=:user_country,

第三 用户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();

尝试此代码

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。

而不是使用所有这些绑定。。。。。。。您只需使用数组方法。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,

));


}

`user_username`=:user_name,

您有（此处缺少冒号）

而不是

`user_name`=:user_name,

 `user_country`=:user_country,

第三 用户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();

尝试此代码

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。

而不是使用所有这些绑定。。。。。。。您只需使用数组方法。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,

));

错误很明显。。查询中PDO名称变量的数量与您使用

bindParam（）

绑定时的数量不同，实际上@product此编辑将直接显示缺少的topicstarter。。Topicstarter SQL应该是可读的，将SQL编写为“一行”而没有良好格式是10倍麻烦中的9倍。您缺少一个
