Facebook App, login and stream.publish with PHP not working

Question

I created and application in facebook (it's in "sandbox mode"). I added a "connect to facebook" button in a page. The login works OK, but when I try to use the method stream_publish, I get that error :

Uncaught exception 'FacebookRestClientException' with message 'The user hasn't authorized the application to perform this action' in 

I noticed that when I log in, it doesn't say "Publish content to your Wall" in the login popup. I see that when I log in on digg.com with the facebook connect button, but I don't see that in my app.

So do I need to set some kind of settings in my application settings... Is there another of login a user that will grant my application to post data on his stream?

Update #1

This is the line I use to edit my stream :

$this->facebook_connect->client->stream_publish($message,null,null,XXXXXX,XXXXXXXX); Where XXXXXXX is my user id on FB.

Update #2 When I log in my profile on FB, go to "Account", "Application Settings", "Edit settings" on my application, I don't see the "Publish content to my Wall" as in the "Events" application...

Answer 1

You have to have the publish_stream permission in order to publish to the stream. I know that sounded obvious, but in order to get this permission, and other extended permissions, you have to specifically request them. I don't know exactly how to do this with PHP, but these links might help:

Extended Permissions

Abra kadabra

$session = $facebook->getSession();
$loginUrl = $facebook->getLoginUrl(
        array(
        'canvas'    => 1,
        'fbconnect' => 0,
        'req_perms' => 'publish_stream'
        )
);
