Facebook Graph API PHP SDK posting on page as page

Question

It\'s final try with PHP, if it fails, I\'ll try with JS. So my goal is to post on FB page as \"Page name\" through PHP: this is what I want to get

Answer 1

I struggled with this most of the day, then found that not using setAccessToken(page_access_token) was the only thing preventing it from working for me. I found that in a stackoverflow post from 18 months ago. I'll put my solution here, for anyone who has this question in the future:

protected $scope = "email,publish_stream,manage_pages";

    $url = "{$api_url}/{$fbusername}/accounts?access_token=".$access_token;
    $response = json_decode(file_get_contents($url));
    foreach($response->data as $data) {
        try
        {
            $res = $this->SDK->setAccessToken($data->access_token);
            $res = $this->SDK->api(
                "{$data->id}/feed",
                "POST",
                array('link' => 'www.example.com',
                      'message' => 'This is a test message from php',)
            );
            log::debug(__FUNCTION__, print_r($res,true));
        }
        catch (Exception $e)
        {
            log::debug(__FUNCTION__, $e->getType().": ".$e->getMessage());
        }

    }

$feed = '/v2.8/' . $pageID . '/' . "feed";
$params = array(
 "access_token" => AQUI TU TOKEN // see: https://developers.facebook.com/docs/facebook-login/access-tokens/
);
$params[ "link" ] = "https://zapatillasnewbalancebaratas.blogspot.com/2018/11/zapatilla-new-balance-ml515-col.html";
$params[ "message" ] = "Zapatilla New Balance Ml515 Col";
$params[ "method" ] = POST;

$graph_url = "https://graph.facebook.com" . $feed;


        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $graph_url);
        curl_setopt($ch, CURLOPT_HEADER, 0);
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $params);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);

        $output = curl_exec($ch);
        echo $output;
        curl_close($ch);

You'll need to make sure you're requesting the 'manage_pages' permission for the user. Once you've got that you can do $facebook->api('/me/accounts') and you'll receive a token back (along with the page info) that you can use to post on the page as the page.
