MediaWiki	1.7 and above

DPLforum is a heavily-adapted derivation of DynamicPageList 1.12, geared toward displaying forum-style layouts.

New features in version 3.0 include author listings, compact display, and full multipage support. Version 3.1 introduces prefix matching, for better interoperability with CreateBox.

[edit] Parameters

DPLforum expects parameters in the form of a linebreak-separated list of assignments, as shown here.

<table><forum>
 category=CategoryName
 parameter1=value
 parameter2=value
 </forum></table>

[edit] Content parameters

• category={page}: Adds a category to the set of categories. Only pages that belong to each of these categories will be displayed.
• notcategory={page}: Adds a category to the set of exclusions. Only pages that belong to none of these categories will be displayed.
• namespace={text}: Specifies the namespace in which to search. Only one namespace may be specified.
• prefix={text}: Specifies a prefix to match in the title. Only pages whose titles begin with the specified prefix will be displayed. (New in version 3.1)
• start={number}: Excludes the first {number} results from the listing.
• count={number}: Lists no more than {count} results.
• title={page}: If specified, this object becomes a forum-style link to the given page. Other parameters still apply.

[edit] Structural parameters

• mode: Specifies the mode of output.
  • mode=table: Default. Displays each entry in a <tr> block. <table> tags are not included, so that each table may be given custom properties.
  • mode=list: Displays each entry in a <li> block. As above, tags such as <ol> or <ul> are omitted.
  • mode=none: Only separates entries with a <br /> tag.
  • mode=count: Returns only the number of entries that match the given parameters. (New in version 3.2)
• compact: Allows for individual <td> tags to be combined together where appropriate.
  • compact=author: Combines the Title and Author cells.
  • compact=editor: Combines the Edit and Editor cells.
  • compact=all: Combines both.
• addcreationdate=true: Displays each entry's date of creation.
• addauthor=true: Displays the original author of each entry.
• addlasteditor=true: Displays the last editor of each entry.
• addlastedit=false: Hides each entry's last edit time; shown by default.

[edit] Output parameters

• ordermethod: Specifies the order in which entries are listed.
  • ordermethod=lastedit: Default. Sorts entries by the last time they were edited.
  • ordermethod=created: Sorts entries by the time of their creation.
  • ordermethod=pageid: Sorts entries by their ID numbers; usually equivalent to created.
• historylink: Provides a link to each entry's history.
  • historylink=embed: Transforms the Edit field into a history link.
  • historylink=append: Appends the history link onto the Edit field.
• omit={text}: Omits the given text from the beginning of each entry's title.
• order=ascending: Reverses the sort order.
• newdays={number}: Marks all links to entries modified less than {number} days ago with class='forum_new'; defaults to 7.
• timestamp=false: Removes timestamp values from the page links. Timestamps ensure that newly-edited entries don't appear as "visited" links.
• cache=true: Saves the results of this object to the parser cache. This is false by default unless DPLForum::requireCache is set to true.

[edit] Multipage support with #forumlink

The #forumlink parser function creates links to the present page which offset the forum listings by a certain amount. This allows each forum to contain any number of additional "pages". The syntax is as follows:

{{#forumlink:count|page|text}}

• count represents the number of topics per page.
• page specifies the page number, either as an absolute value or a relative offset.
• text sets the link text. If this is left blank, the page number is used instead.

[edit] Relative offsets and page conditions

When specifying the page, if the number is preceded by + or -, then it is assumed to be a relative offset from the present position. Relative links which would link to pages less than 1 are not displayed.

You may also optionally specify a condition after the page number, which the page must meet in order to be displayed. For example, to specify a link to the next page when that page is less than 10, use:

{{#forumlink:30|+1<10|Next page}}

Conditions may use the <, <=, >, and >= operators.

[edit] MediaWiki messages

DPLforum specifies five messages in the MediaWiki: namespace.

• MediaWiki:Forum_by - The word "by".
• MediaWiki:Forum_never - The word "Never".
• MediaWiki:Forum_edited - "Last edited". Separates the title and edit when not in table mode.
• MediaWiki:Forum_toofew - Error message displayed when no categories are given.
• MediaWiki:Forum_toomany - Error message displayed when too many categories are given. This threshold is controlled by DPLForum::maxCategories.

[edit] Code

DPLforum 3.2 has been tested on MediaWiki 1.9, and should run on versions 1.7 and above.
