• Avatar selection/upload during registration: Oddly enough, avatar_selection doesn’t handle this. You need the reg_with_pic module, too.
• Shared and per-site file directories: We’re segregating uploaded files by microsite, but we want to share some files as well. Hacking the shared path into file.inc is a kludge, but it works. Like so:

• Group names with signed-up events: signup.module doesn’t make it easy to theme the list of events, so I created my own block based on the code in signup_list_user_signups. To determine the possible group a node came from, I check for the intersection between $node->og_groups and the array keys of $user->og_groups.
• Fixed panes: I couldn’t figure out a way to set a block as fixed in Panels 2, but a workaround is to define a custom layout that includes the block in the right place. Here’s an example:

  /**
   * Implements hook_panels_layouts
   */
  function mymodule_panels_layouts() {
    $items['my_panel'] = array(
      'title'  => t('My Panel Layout'),
      'icon'   => 'my_panel.png',
      'theme'  => 'my_panel',
      'css'    => 'my_panel.css',
      'panels' => array(
        'top' => t('Top'),
        'left' => t('Left'),
        'right' => t('Right'),
      ),
    )
    return $items
  }
  
  /**
   * This function uses heredoc notation to make it easier to convert
   * to a template.
   */
  function theme_my_panel($id, $content) {
    if ($id) {
      $idstr = " id='$id'"
    }
    // Pull in the Organic Groups - 0 block.
    $group_details = og_block('view', 0)
    $group_block = < <<EOT
    <div class="block block-og" id="block-og-0">               
      <h2 class="title">$group_details[subject]</h2>
      <div class="content">
      $group_details[content]
      </div>
      
  EOT
    $output = < <<EOT
  <div class="panel-2col-stacked clear-block panel-display" $idstr>
    <div class="panel-col-top panel-panel">
      <div class="inside">$content[top]</div>
    </div>
      <div class="center-wrapper">
      <div class="panel-col-first panel-panel">
      <div class="inside">
      $content[left]
      </div>
      </div>
      <div class="panel-col-last panel-panel">
      <div class="inside">
      $group_block
      $content[right]
      </div>
      </div>
    </div>
    <div class="panel-col-bottom panel-panel">
      <div class="inside">$content[bottom]</div>
    </div>
  EOT
    return $output;
  }
  

  To limit the choices to just that layout, put this in your installation profile:

    panels_load_include('common');
    $allowed_layouts = new panels_allowed_layouts();
    $allowed_layouts->allow_new = TRUE;
    $allowed_layouts->module_name = 'panels_common';
    $allowed_layouts->allowed_layout_settings = array(
      'threecol_33_34_33_stacked' => 0,
      'twocol' => 0,
      'flexible' => 0,
      'threecol_25_50_25' => 0,
      'threecol_25_50_25_stacked' => 0,
      'onecol' => 0,
      'threecol_33_34_33' => 0,
      'twocol_stacked' => 0,
      'twocol_bricks' => 0,
      'my_panel' => 1
    );
    $allowed_layouts->api_save();
  

• Organic Groups RSS feed: There’s an og_aggregator module, although it doesn’t quite fit in neatly with everything else.
• Organic Groups tag cloud: I was surprised to find that this wasn’t built in. I ended up defining my own block using a SQL query like this:

          if (($node = og_get_group_context()) && node_access('view', $node)) {
            $result = db_query(
              'SELECT COUNT(*) AS count, d.tid, d.name, d.vid FROM {term_data} d
               INNER JOIN {term_node} n ON (d.tid=n.tid)
               INNER JOIN {og_ancestry} og ON (og.nid=n.nid)
               WHERE og.group_nid=%d AND d.vid=0 GROUP BY d.tid, d.name, d.vid ORDER BY count DESC', $node->nid);
            $steps = 6;
            $tags = tagadelic_build_weighted_tags($result, $steps);
            $tags = tagadelic_sort_tags($tags);
            $output = theme('og_tagadelic_weighted', $node, $tags);
            $block['content'] = $output;
          }
  

  og_tagadelic_weighted was a custom theme function that constructed a link to a faceted_search using the og: and taxonomy: filters. I had to hack faceted_search, too. First I needed to enable the og filter, and then I needed to make taxonomy_facets.module recognize free tags (vid=0). Patch for taxonomy_facets.module:

It’s a good thing I can find my way around sparsely-documented code with few or no examples… <laugh>
