What are the prerequisites for Facebook stream.publish?

Question

Hi, I'm wondering if someone would help me troubleshoot my test for stream.publish. I thought I had all the right pieces. Here's the code:

<?php
require_once 'facebook.php';
$appapikey = 'xxxxxxx';
$appsecret = 'xxxxxxx';
$facebook = new Facebook($appapikey, $appsecret);
$user_id = $facebook->require_login();


$message = "Will this status show up and allow me to dominate the world?!";
$uid = $user_id;
echo $uid;
$facebook->api_client->stream_publish($message,$uid);

What I'm expecting is my status to change to $message's content. What happens instead is that my UID is echo'd, and then it throws a 500 error. I've allowed publish_stream as well as offline_access (verified in my app settings, via my profile), the the API key hooks this small bit of code to my app. What other pieces do I need to make this simple example work? I'm finding the FB documentation a little hard to put together.

-- The include is the official PHP Facebook library

Answer 1

Remove the $uid variable as it is not needed for publishing. Refer to this wiki entry for more info

$stream_post_id = $facebook->api_client->stream_publish($message); 
//returns $post_id to use if you want to revert the creation.

Answer 2

stream_publish() takes more than two arguments:

stream_publish($message, $attachment = null, 
               $action_links = null, $target_id = null, 
               $uid = null)

Where $target_id is the user or page you're publishing to and $uid is the user or page who is doing the publishing - and which defaults to your session id. To be completely explicit about this, I think you need to try

<?php
require_once 'facebook.php';
$appapikey = 'xxxxxxx';
$appsecret = 'xxxxxxx';
$facebook = new Facebook($appapikey, $appsecret);
$user_id = $facebook->require_login();

$message = "Will this status show up and allow me to dominate the world?!";

echo $user_id;
$facebook->api_client->stream_publish($message,null,null,$user_id,$user_id);

An alternate form might be:

$app_id = 'xxxxxxx'; 
$facebook->api_client->stream_publish($message,null,null,$user_id,$app_id);

Here is a Simple 5 step code to post on a wall without login to application. http://blog.theunical.com/facebook-integration/5-steps-to-publish-on-a-facebook-wall-using-php/

Answer 4

i followed that 5 step guide, but it requires user to type urls and copy paste codes to post, is there any way to automatize it?

Answer 5

I'm using the code below:

<?php
$facebookinclude = '../facebook-platform/php/facebook.php';

$appid = 'XXXXXX';

require_once($facebookinclude);

$facebook = new Facebook('XXXXXX', 'XXXXXX');

$user_id = $facebook->require_login();

$message = "Test Message";

echo $user_id;

$facebook->api_client->stream_publish($message,null,null,$user_id,$appid);

?>

But I also get a 500 error, right after the user id is echoed...

I've also tried this:

$facebook->api_client->stream_publish($message,null,null,null,null);

and this

$app_id = 'xxxxxxx'; 
$facebook->api_client->stream_publish($message,null,null,$user_id,$app_id);

but with the same result...

Is there any way to get a more meaningful error message? Can anyone spot what is wrong with my code...?
