FB App cant post Image to page? - php

Question

I recently created a Facebook App to send visualized data (image) to pages which are already belongs to same user account as The App.
Also, I set extended permissions in Permissions Pane of App. Setting Page.
Here are the codes that can send post in text format. But when I tried to send images attached it fails.
What are the possible mistakes that I can't get at the moment?
$facebook = new Facebook(array(
'appId' => MY_APP_ID,
'secret' => MY_APP_SECRET,
'fileUpload' => true,
'allowSignedRequest' => false
));
$img = "../../../tw-data/postImages/twpostimage-usd.png";
$message = 'Activity Test with Image # ' . date('d.M.Y H:i:s');
try
{
$access_token = $facebook->getAccessToken();
$params = array('access_token' => $access_token,
'source' => '#'.$img,
'message' => $message
);
$result = $facebook->api('/'. MY_PAGE_ID .'/feed','POST', $params);
print_r($result);
}
catch (FacebookApiException $e)
{
$login_url = $facebook->getLoginUrl();
echo 'Please login.';
error_log($e->getType());
error_log($e->getMessage());
}

Answer 1

What Errors are you getting when you try this?
I believe the main issue you're having is that you're posting to
/my_page_id/feed
where you should be posting to
/my_page_id/photos
From the facebook docs
$response = $facebook->api(
"/me/photos",
"POST",
array (
'url' => '{image-url}',
)
);
EDIT:
I have successfully posted an image with a message using the following format.
$img = 'FILE_NAME.jpg';
$message = 'Activity Test with Image # ' . date('d.M.Y H:i:s');
$params = array('access_token' => $access_token,
'message' => 'test',
'source' => '#'.$img
);
$result = $facebook->api('/USER_ID/photos','POST', $params);
print_r($result);

Also, I set extended permissions in Permissions Pane of App. Setting
Page.
That's a common mistake. Permissions have to be requested in your scope, not in the app settings.
$params = array(
'scope' => 'publish_stream',
'redirect_uri' => 'https://www.myapp.com/post_login_page'
);
$loginUrl = $facebook->getLoginUrl($params);
Accept the permissions dialog and try again. If you want to post to the page as page, obtain a page access token.
Happy Coding!
