As you know that Facebook introduced new Graph API v3.1 on July 26, 2018 that changed many things for developers. One of the questions I have now is how to share/post on Facebook profile/page timeline using Facebook Graph API v3.1 PHP SDK?

为此，我创建了一个具有某些设置的新应用，如以下屏幕截图所示.

For this I created a new apps with some settings as shown in the below screenshots.

为此，我使用了下面提到的代码以及 facebook-php-graph-sdk -5.x .

For this purpose, I used the below mentioned code along with facebook-php-graph-sdk-5.x.

<?php
if(!session_id()){
    session_start();
}

// Include the autoloader provided in the SDK
require_once __DIR__ . '/facebook-php-graph-sdk-5.x/autoload.php';

// Include required libraries
use Facebook\Facebook;
use Facebook\Exceptions\FacebookResponseException;
use Facebook\Exceptions\FacebookSDKException;

/*
 * Configuration and setup Facebook SDK
 */
$appId         = 'APP_ID'; //Facebook App ID
$appSecret     = 'APP_SECRET'; //Facebook App Secret
$redirectURL   = 'MAIN_PAGE_URL_SAME_AS_IN_APPS_SETTING'; //Callback URL
$fbPermissions = array('publish_actions'); //Facebook permission

$fb = new Facebook(array(
    'app_id' => $appId,
    'app_secret' => $appSecret,
    'default_graph_version' => 'v2.6',
));

// Get redirect login helper
$helper = $fb->getRedirectLoginHelper();

// Try to get access token
try {
    if(isset($_SESSION['facebook_access_token'])){
        $accessToken = $_SESSION['facebook_access_token'];
    }else{
        $accessToken = $helper->getAccessToken();
    }
} catch(FacebookResponseException $e) {
     echo 'Graph returned an error: ' . $e->getMessage();
      exit;
} catch(FacebookSDKException $e) {
    echo 'Facebook SDK returned an error: ' . $e->getMessage();
      exit;
}
?>

index.php

<?php
// Include FB configuration file
require_once 'fbConfig.php';

if(isset($accessToken)){
    if(isset($_SESSION['facebook_access_token'])){
        $fb->setDefaultAccessToken($_SESSION['facebook_access_token']);
    }else{
        // Put short-lived access token in session
        $_SESSION['facebook_access_token'] = (string) $accessToken;

        // OAuth 2.0 client handler helps to manage access tokens
        $oAuth2Client = $fb->getOAuth2Client();

        // Exchanges a short-lived access token for a long-lived one
        $longLivedAccessToken = $oAuth2Client->getLongLivedAccessToken($_SESSION['facebook_access_token']);
        $_SESSION['facebook_access_token'] = (string) $longLivedAccessToken;

        // Set default access token to be used in script
        $fb->setDefaultAccessToken($_SESSION['facebook_access_token']);
    }

    //FB post content
    $message = 'Test message from *.com website';
    $title = 'Post From Website';
    $link = 'http://www.*.com/';
    $description = '* is simply awesome.';
    $picture = 'https://i.stack.imgur.com/MybMA.png';

    $attachment = array(
        'message' => $message,
        'name' => $title,
        'link' => $link,
        'description' => $description,
        'picture'=>$picture,
    );

    try{
        // Post to Facebook
        $fb->post('/me/feed', $attachment, $accessToken);

        // Display post submission status
        echo 'The post was published successfully to the Facebook timeline.';
    }catch(FacebookResponseException $e){
        echo 'Graph returned an error: ' . $e->getMessage();
        exit;
    }catch(FacebookSDKException $e){
        echo 'Facebook SDK returned an error: ' . $e->getMessage();
        exit;
    }
}else{
    // Get Facebook login URL
    $fbLoginURL = $helper->getLoginUrl($redirectURL, $fbPermissions);

    // Redirect to Facebook login page
    echo '<a href="'.$fbLoginURL.'"><img src="https://www.freeiconspng.com/uploads/facebook-login-button-png-11.png" /></a>';
}

?>

我的文件级别如以下屏幕快照所示.

Where as my files level are as shown in the below screenshot.

最后，在完成所有上述设置和代码后，当我尝试运行页面时，我得到了登录脸部按钮，然后单击此处，则出现以下屏幕截图错误.

Finally after doing all of the above setting and codes, when I try to run my page then I got LOGIN FACEBOOK BUTTON and after clicking there, I got the below screenshot error.

我想要的是简单地发布我想要的内容，而不显示任何POPUP或对话框，以便我可以通过我的PHP代码轻松使用它.

What I want is simple post my desired content without showing any POPUP or dialog so that I can easily use it via my PHP Codes.

我试图在Internet上找到任何可行的解决方案，但现在它们都已过时，现在无法与新的Facebook Graph API v3.1一起使用.

I tried to find any working solution over internet but all are now old, nothing is now working with new Facebook Graph API v3.1.
