Question

当我尝试登录我的项目时，我陷入了一个项目它显示了我

致命错误：在非对象中调用成员函数getid（）第31行的C：\ wamp \ www \ p3 \ controller \ backend.php

我认为这是与我的backend.php文件+ AdminManager.php文件+ Author.php文件有关的问题

这是我的backend.php文件

enter code here

<?php

// Chargement des classes
require_once('model/PostManager.php');
require_once('model/CommentManager.php');
require_once('model/AdminManager.php');

   //use \wwww\p3\model\AdminManager;

 function login()
  {
 require('view/frontend/connectView.php');
 }

function connexion($pseudo,$motdepasse)
 {
    //$postManager = new www\p3\model\PostManager();
   // Création d'un objet
$adminManager = new www\p3\model\AdminManager();
  //$adminManager = new AdminManager();
$resultat = $adminManager->connected($pseudo,$motdepasse);



if (!$resultat)
{
 echo  'Mauvais identifiant ou mot de passe !';
}
else
{


 $_SESSION['id'] = $resultat->getId();
 $_SESSION['pseudo'] = $resultat->getPseudo();
 header('Location: index.php?action=board');

      }




   }

function board()
   {



 $commentManager = new www\p3\model\CommentManager();

这是我的AdminManager.php文件

<?php
namespace www\p3\model;
require_once("model/Manager.php");
require_once("model/Author.php");

class AdminManager extends Manager
  {

   public function connected ($pseudo,$motdepasse)
  {
 $db= $this->dbConnect();
 $req = $db->prepare('SELECT id,nom,prenom,pseudo,motdepasse FROM auteur 
  WHERE pseudo=:pseudo AND motdepasse=:motdepasse');
 $req->execute(array('pseudo' => $pseudo,'motdepasse' => $motdepasse));
 $req->setFetchMode(\PDO::FETCH_CLASS|\PDO::FETCH_PROPS_LATE, "Author");
 $resultat = $req->fetch();
   return $resultat;
 }

}

这是我的Author.php文件

<?php
namespace www\p3\model;
/**
* Classe which represents an author
* @author David P.
* @version 0.1.0
*/
  class Author

  {
  /**
    * @var $id
    */
  private $id;
  private $firstname;
  private $lastname;
  private $pseudo;
  private $password;
// SETTERS
public function setId($id)

{
    $this->id = (int)$id;
}
public function setFirstname($firstname)

{
    $this->firstname = $firstname;
}
public function setLastname($lastname)

{
    $this->lastname = $lastname;
}
public function setPseudo($pseudo)

{
    $this->pseudo = $pseudo;
}
public function setPassword($password)

{
    $this->password = $password;
}

//GETTERS
public function getId()

{
    return $this->id ;
}
public function getFirstname()

{
    return $this->firstname ;
}
public function getLastname()

{
     return $this->lastname ;
}
public function getPseudo()

{
    return $this->pseudo ;
}
public function getPassword()

{
    return $this->password ;
}
}
   ?>

Answer 1

返回$ resultat; -不返回对象。

Answer 2

我认为这可能会导致包含和要求

当可能需要多次包含被调用文件时，

require_once（）语句可用于在另一个文件中包含一个php文件。如果发现该文件已被包含，则调用脚本将忽略其他包含。当您可能需要多次包含被调用文件时，include_once（）语句可用于在另一个文件中包含一个php文件。如果发现该文件已被包含，则调用脚本将忽略其他包含的文件。

如果a.php是一个使用require_once（）语句调用b.php的php脚本，但未找到b.php，则a.php停止执行会导致致命错误。

<?php
namespace www\p3\model;
include_once("model/Manager.php");
include_once("model/Author.php");

class AdminManager extends Manager
{

public function connected ($pseudo,$motdepasse)
  {
$db= $this->dbConnect();
$req = $db->prepare('SELECT id,nom,prenom,pseudo,motdepasse FROM auteur
  WHERE pseudo=:pseudo AND motdepasse=:motdepasse');
$req->execute(array('pseudo' => $pseudo,'motdepasse' => $motdepasse));
$req->setFetchMode(\PDO::FETCH_CLASS|\PDO::FETCH_PROPS_LATE, "Author");
$resultat = $req->fetch();
   return $resultat;
}

}
还要更改这些：-
include_once('model/PostManager.php');
include_once('model/CommentManager.php');
include_once('model/AdminManager.php');
