Facebook Graph API PHP SDK posting on page as page - php

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
But all I get is shown pic below. Also, it's visible ONLY to this profile (not to friends/ppl who like/etc.).
This is my current code
function post_facebook($data=null, $redir = null){
$result = "";
require_once (ROOT. "/apps/configuration/models/ConfigurationItem.php");
require_once (ROOT . "/components/facebook/facebook.php");
$this->ConfigurationItem = new ConfigurationItem($this->getContext());
$row=$this->ConfigurationItem->findByCatKeyItemKey('system','facebook_login');
$apiid=$row['value']; <= Correct apiid
$row=$this->ConfigurationItem->findByCatKeyItemKey('system','facebook_pass');
$secret=$row['value']; <= Correct secret key
$facebook = new Facebook(array(
'appId' => $apiid,
'secret' => $secret,
'cookie' => true,
));
$session = $facebook->getSession();
$me = null;
if ($session) {
try {
$uid = $facebook->getUser();
$me = $facebook->api('/me');
} catch (FacebookApiException $e) {
error_log($e);
}
$message=$data['facebook_text'];
$attachment = array(
'message' => $data['facebook_text'],
'name' => $data['name'],
'link' => $this->getLinkToLatestNews(),
'description' => '',
);
try {
$facebook->api('/PAGE ID/feed/', 'post', $attachment);
$result = "Facebook: Sent";
} catch (FacebookApiException $e) {
$result = "Facebook: Failed";
error_log($e);
}
} else {
$login_url = $facebook->getLoginUrl();
header("Location: ".$login_url);
exit;
}
echo $result;
exit;
//return $result;
}
What I'm doing wrong? I couldn't find anything in API documentation/top google results, only for JS. Thanks for help!

Answer 1

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.

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);
