Extending Embed + The Embed plugin can be extended by other plugins using a combination + of plugin hooks and specific views. + + Plugins can register a new content section or a new upload section. + + Plugins can also provide special views for their embed section, if + they require something the default view doesn't provide. + + +2.1 Registering and Populating Embed Sections + Plugins providing embed content should reply to two hooks: embed_get_sections:all + and embed_get_items:$section_name. + + Embed emits the 'embed_get_sections' hook to populate the tabs of the modal display. + Plugins supporting embed should reply by pushing an array element to the passed + $value. + + Register plugins hooks like this: + + register_plugin_hook('embed_get_sections', 'all', 'my_plugin_embed_get_sections'); + + function my_plugin_embed_get_sections($hook, $type, $value, $params) { + $value['videolist'] = array( + 'name' => elgg_echo('my_plugin'), + 'layout' => 'list', + 'icon_size' => 'medium', + ); + + return $value; + } + + The index of the returned array is the id used for the Embed section. + + Options available in the array value are: + name => The friendly name to display in the tab + layout => The layout style to use.

The vars available to you are: - str content The content to insert. - str textAreaName The name of the textarea to receive the content. +2.2 Registering Upload Sections + Embed includes a special tab, Upload, that allows users to immediatley + upload a new item. Like the embed sections, plugins can extend this + to add their own upload form. + + Embed emits the embed_get_upload_sections:all hook to populate the + dropdown in the upload tab. Plugins should respond to this hook + by returning an array with details about the upload section: + + register_plugin_hook('embed_get_upload_sections', 'all', 'my_plugin_embed_get_upload_sections'); + + function my_plugin_embed_get_upload_sections($hook, $type, $value, $params) { + $value['my_plugin'] = array( + 'name' => elgg_echo('my_plugin'), + 'view' => 'my_plugin/forms/embed_upload' + ); + + return $value; + } + + The array index is the ID of the upload section, and the values are: + name - The friendly name of the upload section + view - The view to use for the upload section's content + + The upload form view should use AJAX to upload a file and return + the user to the correct section or automatically insert the new upload + into the text area. See Tidypics as an example. + + +2.3 Advanced Layouts + By default, Embed will automatically format items returned by + embed_get_items hooks. If you need special formatting you can + override both the content and layout views. + + Embed looks for a section-specific views before defaulting to built + in formatting: + embed/$section/content - The content of the embed section + including all headers and navigation elements. + embed/$section/item/$layout - The content of the embed section + for the specific layout. Inserted + between navigation elements. + + Embed also supports adhoc layouts that can be shared among different plugins. + To use a specific layout, register the embed section with your own layout + and create the appropriate layout view: + + function my_plugin_embed_get_sections($hook, $type, $value, $params) { + $value['videolist'] = array( + 'name' => elgg_echo('my_plugin'), + 'layout' => 'shared_embed_layout', + 'icon_size' => 'medium', + ); + + return $value; + } + + Create the views 'embed/layouts/shared_embed_layout' and + 'embed/items/shared_embed_layout.' See the default list and + gallery layouts as examples. + + +2.4 Javascript + If you use a custom layout you need to provide a way to insert + the user's selection into the current editor. Usually this will be + an onClick event via Javascript. Embed provides a helper function for + this: + + elggEmbedInsertContent(content, textAreaName) + + Content is the pre-formatted content to insert into the text area, + and textAreaName is the name of the text area. This name is + sent via GET as 'internal_name.' + + +3. Other Editors and Embed + Embed ships with support for the default input/longtext textarea. + Plugins replacing this view are expected to include Javascript to + allow embed to work with the new editors. + + The elggEmbedInsertContent() JS function can be extened for custom + text editors by extending the embed/custom_insert_js view. Plugins + should extend this view with javascript code that inserts + content into the specific text area. Variables available within + this view are: + str content The content to insert. + str textAreaName The name of the textarea to receive the content. -It is important to correctly extend this view for compatibility across -multiple plugins and textarea states. Your custom JS should run without -error no matter plugin order or rich text editor status. See TinyMCE as -an example of how to losely extend this function.
