Question

Is there a way to send data (like update status or post to friend’s wall) to Facebook using Facebook’s batch API. I wish to post to multiple friend’s wall or something similar with just one call to Facebook API.

$users = array();

$users[] = array('method' => 'POST', 'relative_url' => '/me/feed', 'body' => "message=Test status update");

try{

    $batchResponse = $facebook->api('?batch='.json_encode($users), 'POST');

}catch(FacebookApiException $e){

    error_log($e);

}

But the script fails and the API call returns NULL. Can some one help me with the right way to do this.

Thanks in advance.

It fails because you don’t pass a URL-encoded query string to the api() function. Using http_build_query() when building the array and urlencode() before the batch request will solve the issue.

$batchPost[] = array(
                'method' => 'POST',
                'relative_url' => "/$value/feed",
                'body' => http_build_query($body)
                );

$multiPostResponse = $facebook->api(
                '?batch='.urlencode(json_encode($batchPost)),
                'POST'
                );
