Call to undefined method FacebookRestClient::set_user()

Some more information added the following lines to facebook-platform/php/facebook.php just before the error throwing line 81:

suprisingly, the last print was output prior to the same fatal error.

api_client->set_user should be defined

Fatal error: Call to undefined method FacebookRestClient::set_user() in /usr/www/users/stout/resolve_ticode.com/teamtracker/sites/all/modules/fb/facebook-platform/php/facebook.php on line 95

Could this be something weird from the facebook side?

In my copy I see set_user defined. You have to use PHP5. PHP4 will not do.

I don't know what the problem is but you seem to be the only one (or first) to report it.

Using PHP5, but my question about PHP4 was due to all the docs talking about PHP4, we use 5 on all my servers.

I've moved to another project for a few weeks, I'll be happy to go into details in a few weeks on this.

Had a spare moment,

1. hacked fb/facebook-platform/php/facebookapi_php5_restlib.php:
   1. changed __construct's function signature to:
      public function __construct($api_key, $secret, $session_key=null, $user=null)
   2. added these lines to end of function __construct:
      <?php
    if ($user)
    {
      $this->set_user($user);
    }
?>
2. hacked fb/facebook-platform/php/facebook.php
   1. modified function __construct:
      1. moved assignment for $this->api_client below the if block for defaultUser
      2. modified FacebookRestClient constructor call to pass the $defaultUser
      3. commented out the ->set_user($defaultUser); call
      Final form:
      
      <?php
  public function __construct($api_key, $secret, $generate_session_secret=false) {
    $this->api_key                 = $api_key;
    $this->secret                  = $secret;
    $this->generate_session_secret = $generate_session_secret;
    $this->validate_fb_params();


    // Set the default user id for methods that allow the caller to
    // pass an explicit uid instead of using a session key.
    $defaultUser = null;
    if ($this->user) {
      $defaultUser = $this->user;
    } else if ($this->profile_user) {
      $defaultUser = $this->profile_user;
    } else if ($this->canvas_user) {
      $defaultUser = $this->canvas_user;
    }  
    $this->api_client = new FacebookRestClient($api_key, $secret, null, $defaultUser);
    /* $this->api_client->set_user($defaultUser); */

    if (isset($this->fb_params['friends'])) {
      $this->api_client->friends_list = explode(',', $this->fb_params['friends']);
    }  
    if (isset($this->fb_params['added'])) {
      $this->api_client->added = $this->fb_params['added'];
    }  
    if (isset($this->fb_params['canvas_user'])) {
      $this->api_client->canvas_user = $this->fb_params['canvas_user'];
    }  
  }
?>

Apparently there's some sort of scoping issue in the facebook library, as if public function set_user was somehow private. Rather than solve their problem, I just hacked around it.

With the above changes I could make the first facebook application save.

It still churns my butter that I had to hack the FB stuff, and that I'm the only one (so-far) to hit this snag, but if it works, I guess we can't complain too much.

Yeah this sounds weird. Sure you have the latest client libs? There's no older copy or some other facebook module around?

You could look this up on facebook's forums. If you like being ignored, you could submit an issue to their bug tracker. Until it bites me, I don't have time to investigate. But thanks for posting details.

Thank you so much for posting a work around! I was getting the same error and your changes did the trick.

I'm using the brand new library, and getting this problem ... there maybe be another copy of the same library, but they're all in different parts of the directory tree, and I use the sites/default/settings.php option to force fb to use the library in the sites/all/modules/fb/facebook-platform/php/

with:

So it may be worthwhile to post a link to this issue somewhere in the module fb docs?? In case more than librarysarah and I run into this.

@sarah, I'm glad my hacking was useful. Too bad it's likely to be ignored by the FB developers :(

Dang, messed up the title LOL

there maybe be another copy of the same library, but they're all in different parts of the directory tree

The idea of the $conf['fb_api_file'] setting is so that if you have to use two modules which both need the facebook client libs, you can install them in just one place and tell Drupal for Facebook where to find them. So if you have some other module which includes those libs, use $conf['fb_api_file'] to find them in that place.

Two copies of those libs is a bad idea. It might be the cause of this problem.

Also I'm curious why you need an additional facebook module. Which one, and what feature are you looking for that the fb modules do not provide?
