php - Facebook Video Upload Curl - php

Question

To upload the video to Facebook using the following lines.
$video = "http://xxx.com/video.mp4";
$data = array('name' => 'file', 'file' => $video,
'access_token' => $access_token, '_title' => $video_title,
'description' => $video_desc);
$post_url = "https://graph-video.facebook.com/" . $page_id . "/videos";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $post_url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$res = curl_exec($ch);
I received an error:
"error":{"message":"(#353) You must select a video file to
upload.","type":"OAuthException","code":353}}
If I change curl to form post it works. Any ideas on why is it so?

Answer 1

Use the path to the video on server instead of the url. So:
$video = "uploads/video.mp4";
Then:
$data = array('name' => 'file', 'file' => '#'.realpath($video),
'access_token' => $access_token, '_title' => $video_title,
'description' => $video_desc);
Notice the use of realpath() following the '#' symbol. Haven't tested with your code but I have a similar implementation and works great. Should do the trick!

For FB SDK4: (see the hardcoded video path, and the encoding).
FB requests the video file to be passed encoded as form-data:
https://developers.facebook.com/docs/graph-api/reference/user/videos/
private function postFBVideo($authResponse, $fileObj, $formData)
{
FacebookSession::setDefaultApplication('yourAppkey', 'yourAppSecret');
$ajaxResponse = '';
try {
$session = new FacebookSession($authResponse->accessToken);
} catch (FacebookRequestException $ex) {
// When Facebook returns an error
$ajaxResponse = 'FB Error ->' . json_encode($ex) ;
} catch (\Exception $ex) {
// When validation fails or other local issues
$ajaxResponse = 'FB Validation Error - ' . json_encode($ex) ;
}
if ($session) {
$response = (new FacebookRequest(
$session, 'POST', '/me/videos', array(
'source' => new CURLFile('videos/81JZrD_IMG_4349.MOV', 'video/MOV'),
'message' => $formDataMessage,
)
))->execute();
$ajaxResponse = $response->getGraphObject();
}
return json_encode($ajaxResponse);
}
