Notes from today’s Drupal hacking
| drupal- 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:
--- file.inc (revision 1046) +++ file.inc (revision 1589) @@ -66,6 +66,11 @@ else if (file_check_location($file_path . '/' . $dest, $file_path)) { return $file_path . '/' . $dest; } + // Not found, check by going up one more + else if (file_check_location($file_path . '/' . $dest, $file_path . '/../')) { + return $file_path . '/' . $dest; + } + // File not found. return FALSE; } - 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'] = $output; }og_tagadelic_weighted was a custom theme function that constructed a link to a faceted_search using the og: and taxonomy: filters. I had to hack faceted_search, too. First I needed to enable the og filter, and then I needed to make taxonomy_facets.module recognize free tags (vid=0). Patch for taxonomy_facets.module:
=================================================================== --- taxonomy_facets.module (revision 1046) +++ taxonomy_facets.module (revision 1582) @@ -147,6 +147,7 @@ // and create facets from it. if ($found_text = search_query_extract($arg, 'taxonomy')) { $vocabularies = taxonomy_get_vocabularies(); + $vocabularies[0] = 1; // Extract separate facets $paths = explode(',', $found_text); foreach ($paths as $path_index => $tids) {
It’s a good thing I can find my way around sparsely-documented code with few or no examples… <laugh>
