php facebook sdk wordpress

Question

Düzenlenen söz konusu kullanıcıyı yaratmaz:

Im kullanarak wordpress sitesinde bir facebook giriş eklentisi yapmaya çalışıyorum this sdk

Giriş yapmaya facebook butonuna tıkladığınızda ya da kayıt oluncaya kadar devam ediyor diyen facebook üzerinden küçük bir pencere açılır, ancak daha sonra wordpress veritabanında kullanıcı yaratmaz ve wordpress altbilgisini keser, bu yüzden sayfa yenilendikten sonra giriş formu altında An active access token must be used to query information about the current user. mesajını gösterir.

Benim tam facebook giriş php kod biridir:

Herhangi birinin ti nasıl çalıştığını biliyor mu? Ne yanlış yapıyorum Herhangi bir yardım çok takdir edilir.

Teşekkür ederim.

GÜNCELLEME:

Ben here

bu Değişti Bu yanıtı kullanarak dosyadaki bazı satırları değişti: $ fbuser = $ facebook-> GetUser();

  if ($fbuser) { 

       try { 

        $user_profile = $facebook->api('/me'); 

       } 

       catch (Exception $e) { 

        echo $e->getMessage(); 

        exit(); 

       } 

kimse bu kadar:

$fbuser = $facebook->getUser(); 

$photo_details = array('message' => 'my place'); 
$file='photos/my.jpg'; //Example image file 
$photo_details['image'] = '@' . realpath($file); 

if ($fbuser) { 
    try { 
    // We have a valid FB session, so we can use 'me' 
    $upload_photo = $facebook->api('/me/photos', 'post', $photo_details); 
    } catch (FacebookApiException $e) { 
    error_log($e); 
    } 

şimdi kayıtlı var ama wordpress onun çok garip

kullanıcı adı ve takma isim daima @facebook: D

Yani bence Buradaki değişkenleri alamıyor:

Lütfen aşağıdaki örnek kodu bulun. Giriş için JavaScript SDK kullanımını ve erişim belirteci oluşturmak için PHP SDK'yı kullandım. Umarım senin için çalışacaktır.

** HTML Kod :: **

<html> 

    <body> 

    <p><a href="#" onClick="logInWithFacebook()">Log In with the JavaScript SDK</a></p> 

    <script> 
    logInWithFacebook = function() { 
     FB.login(function(response) { 
     if (response.authResponse) { 
      alert('You are logged in &amp; cookie set!'); 
      location.href = "//localhost/facebook/testfb.php" 
      // Now you can redirect the user or do an AJAX request to 
      // a PHP script that grabs the signed request from the cookie. 
     } else { 
      alert('User cancelled login or did not fully authorize.'); 
     } 
     }); 
     return false; 
    }; 
    window.fbAsyncInit = function() { 
     FB.init({ 
     appId: 'app-id', 
     cookie: true, // This is important, it's not enabled by default 
     version: 'v2.9' 
     }); 
    }; 

    (function(d, s, id) { 
     var js, fjs = d.getElementsByTagName(s)[0]; 
     if (d.getElementById(id)) { 
     return; 
     } 
     js = d.createElement(s); 
     js.id = id; 
     js.src = "//connect.facebook.net/en_US/sdk.js"; 
     fjs.parentNode.insertBefore(js, fjs); 
    }(document, 'script', 'facebook-jssdk')); 
    </script>
