pageindex plugin by Kite
Bulleted list of pages within a namespace

Last updated on 2006-08-01. Provides Syntax.
No compatibility info given!

Similar to nstoc.

Tagged with listing, menu, namespace, navigation.

    Usage

    You can use one of two tag styles:

    • ~~PAGEINDEX=section:namespace~~ ← Lists the specified namespace.
    • ~~PAGEINDEX~~ ← Lists the current namespace.

    I found that on the http://www.puzzlers.org website, we have sections which get lots of pages over a short time and cross-referencing was a chore since some users aren't as wiki-oriented as others. Now I just add a tag to each page and they automatically update over time.

    The list will not include the current page, either, to reduce confusion.

    Installation

    Put the following code into lib/plugins/pageindex/syntax.php in your DokuWiki site. Then you can add the tags above into any page you want a namespace index.

    The Code

    Updates

    Oct 3, 2006

    I added a bit of code into the “meat” function that performs a neat bit for me. I want to use a syntax of “show me everything except one or two. That is, I have a default “start” or “index” page that has no real content except a ~~pageindex~~ macro. I want to show all the pages except that start page from other pages. Now I can use: ~~pageindex=namespace;except1;except2~~ to get all the pages in namespace other than except1 or except2.

    I changed references to '/' to DIRECTORY_SEPARATOR per the 'possible bug' comment below.

    Discussion

    Listing of subNamespace

    I need also a listing of the namespace under the current namespace. How i have to modify the code? Can you show me an example. Thanks, Johann.

    Possible bug?

    Thanks for the plugin, it's very handy. But I have to say I guess I found a bug. If working on Windows (I test my websites on Windows but host them on Linux/FreeBSD then) the hard-coded slashes in the code (I mean like that: /) cause the bug. Windows puts backslashes in directory path and the plugin, quite contrary, adds slashes. It works OK until no arguments are specified (just ~~PAGEINDEX~~), but if something like ~~PAGEINDEX=dev;sidebar~~ is tried then it starts telling there are no documents to index. Please replace ALL hard-coded slashes to something platform-independent. Regards, Webmaster.

    2007/12/30 I've altered the lines with '/' constants to use the DIRECTORY_SEPARATOR constant so paths should now be more platform independent.

    User Comments

    We had to replace the line 

    // New Oct 3, 2006 -- end
$ns  = cleanID(getNS("$data:dummy"));

    with 

    // New Oct 3, 2006 -- end
$ns  = cleanID(getNS("{$parameters[0]}:dummy"));

    to make the exclude function work. We also had to specify the full pagename including namespace: prefix to actually exclude the page.

    Rüdiger Marwein / Roland Eckert / 21torr.com

    Solution to last thing above

    One way to avoid having to prefix the name space, is to add one line to the $skipitems loop.

    Before snippet:
                foreach($skipitems as $skip) {
               if($item['id'] == $skip) {
                  $found = true;
                  break;


    After snippet:

                foreach($skipitems as $skip) {
               $skip = strpos($skip,":") ? $skip : "$ns:$skip"; // Add ns if user didn't
               if($item['id'] == $skip) {
                  $found = true;
                  break;


    Henrik Andreasson.

    Bug: after copying the script from the page above I got a PHP error on my next “save page” click. I had to remove the ?> part of the last line of the script and it functioned since.

    It is reported here about this problem in general: php_closing_tags - Stephen (stephen-dot-leedle-at-gmx-dot-de)

    I prefer the pagelist plugin for rendering. It's easy to add : Just replace theses lines : 

    			$renderer->doc .= html_buildlist($checked,
				'idx',
				'html_list_index',
				'html_li_index');

    by 

                $pages = $checked;
            $pagelist =& plugin_load('helper', 'pagelist');
            if (!$pagelist) return false; // failed to load plugin
            $pagelist->startList();
            foreach ($pages as $page){
                $pagelist->addPage($page);
            }
            $renderer->doc .= $pagelist->finishList();

    You can set flags too with 

                $pagelist->setFlags(array("nouser", "desc")); // Just after $pagelist->startList();

    I don't know why, but it don't work with “tag” and “comments” flags. Any idea ? (I have both plugins installed)

    — Jean-Michel 2008-03-02 18:26

    :!: Possible bug

    I really like this plugin, but I think I've found a bug. When I create a new page in a namespace, it doesn't appear on the list created by the plugin, but if I make a preview of the page it does appear.

    May it be a problem of refreshing?

    Ayla 2008-04-06 18:40

    try to to a on the page with the ~~PAGEINDEX~~ . Every Page is cached in plain-HTML for a given time if not modified or with that tag.

    :!: Possible bug: No unicode (cyrillics, for example) support.
