Posting on Facebook wall from Codeigniter app - facebook

Question

I have a CI-based app that allows users to post an update stream similar to Facebook's wall.
Currently, users can authenticate into my app via Facebook using FB connect.
I would like to offer the possibility of a user -- when posting to my app's wall -- also be able to send the same post to his/her Facebook wall.
It seems clear the FB's Graph API support this but I'm having a hard time in finding a roadmap/ code/ library to help with this. The example on the above link is unhelpful and doesn't give me any idea how to implement this.
For example, how would a controller for this function look like?
I've found Elliot's FB CI library here, but am unsure if this is needed to accomplish what I want.
Any advice is greatly appreciated - thanks.

Answer 1

I would suggest you use Facebook PHP SDK
In your controller just include facebook php sdk eg: https://github.com/facebook/php-sdk/blob/master/examples/example.php
To make a wall post the following code should do the trick:
$wall_post = array('message' => 'this is my message',
'name' => 'This is my demo Facebook application!',
'caption' => "Caption of the Post",
'link' => 'http://mylink.com',
'description' => 'this is a description',
'picture' => 'http://mysite.com/pic.gif',
'actions' => array(array('name' => 'Get Search',
'link' => 'http://www.google.com'))
);
$result = $facebook->api('/me/feed/', 'post', $wall_post);

Answer 2

I ended up using a codeigniter helper function with curl to post to Facebook. Below is the code.
function facebook($data) {
$CI =& get_instance();
$CI->load->model('fk_model');
$token = $CI->fk_model->fk_cookie();
$attachment = array(
'access_token' => $token['access_token'],
'message' => $data['text'],
'link' => $data['link'],
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,'https://graph.facebook.com/' . $token['id'] . '/feed');
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $attachment);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); //to suppress the curl output
$result = curl_exec($ch);
curl_close($ch);
}
