23 * @author: MichaelVanDam, major refactor by JeffDairiki (as AddComment)
24 * @author: Changed as baseclass to AddComment and WikiForum and EditToolbar integration by ReiniUrban.
27 require_once('lib/TextSearchQuery.php');
30 * This plugin shows 'blogs' (comments/news) associated with a
31 * particular page and provides an input form for adding a new blog.
34 * Add <<WikiBlog >> at your PersonalPage and BlogArchive and
35 * BlogJournal will find the Blog entries automatically.
37 * Now it is also the base class for all attachable pagetypes:
38 * "wikiblog", "comment" and "wikiforum"
42 * To have the blog show up on a seperate page:
44 * <<WikiBlog mode=add>>
45 * Create TopPage/Blog with this page as actionpage:
46 * <<WikiBlog pagename=TopPage mode=show>>
48 * To have the main ADMIN_USER Blog appear under Blog and not under WikiBlog/Blog
49 * or UserName/Blog as for other users blogs,
50 * define BLOG_DEFAULT_EMPTY_PREFIX=true
51 * use the page Blog as basepage
52 * and user="" (as default for ADMIN or current user) and pagename="Blog"
53 * in the various blog plugins (BlogArchives, BlogJournal)
57 * It also works as an action-page if you create a page called 'WikiBlog'
58 * containing this plugin. This allows adding comments to any page
59 * by linking "PageName?action=WikiBlog". Maybe a nice feature in
60 * lib/display.php would be to automatically check if there are
61 * blogs for the given page, then provide a link to them somewhere on
62 * the page. Or maybe this just creates a huge mess...
64 * Maybe it would be a good idea to ENABLE blogging of only certain
65 * pages by setting metadata or something...? If a page is non-bloggable
66 * the plugin is ignored (perhaps with a warning message).
68 * Should blogs be by default filtered out of RecentChanges et al???
70 * Think of better name for this module: Blog? WikiLog? WebLog? WikiDot?
72 * Have other 'styles' for the plugin?... e.g. 'quiet'. Display only
73 * 'This page has 23 associated comments. Click here to view / add.'
75 * For admin user, put checkboxes beside comments to allow for bulk removal.
77 * Permissions for who can add blogs? Display entry box only if
78 * user meets these requirements...?
80 * Code cleanup: break into functions, use templates (or at least remove CSS)
