I changed some lines of this code to looks more fun on facebook's wall.

I created a Image Field with CCK module, named field_imagefb to put an image on the streams, in the post and on comments. The modification call the image when use the fb_stream_publish_dialog().

I use the strip_tags PHP function, to correct a little bug that not show the teaser on streams. Drupal use html text and Facebook today only accept plain text. Strip_tags correct this easyly. ;)

I had problems to get the checkboxes to show up in the node edit / comment form.

The problem was that in the hook_form_alter function the first if statement was

if (isset($GLOBALS['fb']) && fb_facebook_user()) {

For some reason the $GLOBALS['fb'] was not set in all cases. I'm using the 3.x-dev version from May 18, 2010.

I changed the hook_form_alter function as a follows to get it work.

function dff_custom_form_alter(&$form, $form_state, $form_id) {
  if (module_exists('fb')) {
    if (fb_facebook_user()) {
      if ($form['#id'] == 'node-form') {
        // Add checkbox to control feed publish.
        $form['dff_custom']['stream_publish'] = array(
          '#type' => 'checkbox',
          '#title' => 'Share on Facebook',
          '#default_value' => TRUE,
        );
      }
      else if ($form['form_id']['#value'] == 'comment_form') {
        // Add checkbox to control feed publish.
        $form['dff_custom']['stream_publish'] = array(
          '#type' => 'checkbox',
          '#title' => 'Share on Facebook',
          '#default_value' => TRUE,
        );
      }
    }
  }
}

If you want to publish to the application's wall, you need to add the parameter target_id = ID_of_application

fb_stream_publish_dialog(array(
                                    'target_id' => 'XXXXXXXXXX'
                                     'user_message' => $user_message,
                                     'attachment' => $attachment,
                                     'action_links' => $actions,
                               ));

With this code a member publish content to his own stream.

When we have facebook connect app with registered members allowing the site with all the "Facebook Extended Permissions" then we can publish new content to their stream just like a "Fan page" publish content to the page members.

Am i right? how can this be done?

I'm trying to publish on FB Wall and I can not make the checkbox appear. I've been debugging the code and, for example, to get any positive result I had to change the following line:

if (isset($GLOBALS['_fb']))

This way it was not working at all.

if (module_exists('fb'))

This way it is still not working, but it seems I'm closer to the solution.

Right now, my problem is that fb_facebook_user() is returning FALSE. What is the module I have to enable to get TRUE? I just want to enable publishing on the Wall and the users MUST be the ones I have on the local system. I mean, the authentication is done using our LDAP server.

Of course, the users will need to have a Facebook user and I still don't see where/when I should provide this data. Maybe I'm misunderstanding something.

Greetings.

Dave after reading through this thread I just want to say Thank you. You have made it quite clear from the beginning of the project the complexity and challenging nature of the module. I think many users expect to pick up the module and use it without really following the development of it. You've done a great job and the more I use it the more I realize the power of it.

Hi,

Just wanted to share something I recently found out regarding this code. I had created a custom .tpl.php file to theme my content type edit form (the form where I wanted the "Share on Facebook" button to appear.

However, for some reason it was appearing below the Save / Preview buttons. Yet, on forms where I hadn't edited the form theme, it appeared above. I got it work using the code:

print drupal_render($form['fbpublish']['stream_publish']);

Which allows you to position that "Share on Facebook" checkbox and text anywhere you like.

Hope this helps someone.

Cheers,

Richard

With October 2nd dev version, I had to change line 88 of fb_example.module from

    if ($form['#id'] == 'node-form') {

to

    if ($form['#id'] == 'page-node-form') {

... to get the 'Share on Facebook' checkbox. Probably a D6 -> D7 namespace convention change.

I couldn't manage to post to my wall yet but thought it might help some to mention that.

Update : the code in this module isn't D7 ready. Here is a working implementation of a hook which works for a D7 node :

// nodeapi disappeared in D7 so you have to use node_insert, node_update and the like
function  fb_example_node_update($node) {
    if (isset($node->stream_publish) && $node->stream_publish) {
      $attachment = array(
        'name' => $node->title,
        'href' => url('node/' . $node->nid, array('absolute' => TRUE)),
        // No more $node->content nor $node->teaser, but fields
        'description' => filter_xss($node->body['und'][0]['value'], array()),
      );
      if ($logo_path = theme_get_setting('logo_path')) {
        $url = url($logo_path, array('absolute' => TRUE));
        $attachment['media'][] = array(
          'type' => 'image',
          'src' => $url,
          'href' => $url,
        );
      }
      $user_message = t('Check out my latest post on !site...',
                        array('!site' => variable_get('site_name', t('my Drupal for Facebook powered site'))));
      $actions = array();
      $actions[] = array(
        'text' => t('Read More'),
        'href' => url('node/' . $node->nid, array('absolute' => TRUE)),
      );
      fb_stream_publish_dialog(array('message' => $user_message,
                                     'attachment' => $attachment,
                                     'action_links' => $actions,
                               ));
    }
  }

Hope it helps.
