無法使用php打印支票

Question

我對某些主題的打印有問題。這個問題是我無法更新我的用戶信息的原因。雖然這個代碼是我認爲正確的。

這是我在editprofile頁面上的代碼。

include_once ("classes/Db.class.php"); 
include_once ("classes/config.class.php"); 
include_once ("classes/user.class.php"); 

session_start(); 
if (!isset($_SESSION['loggedIn'])) { 
    echo("not set"); 
    header("Location:index.php"); 
} 
if (!empty($_POST['update'])) { 
    echo "test 2"; 
    // todo: 1 form input velden ophalen 
    try { 
     $u = new User(); 
     $u->Username = $_POST['form-username']; 
     $u->Email = $_POST['form-email']; 
     $u->Password = $_POST['form-password']; 
     $u->Passwordconfirmation = $_POST['form-passwordconf']; 
     $u->Update($_SESSION['loggedIn']); 
     $u->profileImg($_SESSION['loggedIn']); 
     $succes = "Je gegevens zijn aangepast"; 
    } catch (exception $e) { 
     $succes = $e->getMessage(); 
    } 
} 

這裏是我的user.class.php中的代碼。我想與之交談的具體功能是更新功能。

Answer 1

不是更新分別在三個if塊username，email和password字段，僅使用一個if塊來更新所有三個字段。

所以你update()方法應該是這樣的：

public function Update($userid){ 

    $PDO = Db::getInstance(); 
    if(!empty($this->m_sUsername) && !empty($this->m_sEmail) && !empty($this->m_sPassword) && !empty($this->m_sPasswordconfirmation)){ 
     if($this->m_sPassword == $this->m_sPasswordconfirmation){ 
      $options= ['cost' => 12]; 
      $this->m_sPassword = password_hash($this->m_sPassword, PASSWORD_DEFAULT, $options); 

      $stmt = $PDO->prepare("UPDATE users SET username= :username, email = :email, password = :password WHERE usersid = :usersid"); 
      $stmt->bindValue(":usersid", $userid, PDO::PARAM_INT); 
      $stmt->bindValue(":username", $this->m_sUsername, PDO::PARAM_STR); 
      $stmt->bindValue(":email", $this->m_sEmail, PDO::PARAM_STR); 
      $stmt->bindValue(":password", $this->m_sPassword, PDO::PARAM_STR); 
      if($stmt->execute()){ 
       // success 
       echo "succes"; 
      }else{ 
       // error 
       echo "failure"; 
      } 
     }else{ 
      // Mismatch password 
      echo "mismatch password"; 
     } 
    }else{ 
     // some values are not set 
     echo "some values are not set"; 
    } 
}
