==Do not include template content on dpl list ==

I'm using a template to include footer information on my pages.  How do I *not* make this content from this template not appear on my <nowiki><dpl></nowiki> list?

I'm wondering if DPL can help with my situation. I would like to recreate the "What Links Here" page functionality on an article page. Basically each article would show all of the other pages/articles that refer to it? I've read through this site and it seems DPL is the answer, but I havent read anything specific to this. I'm pretty new to the whole WIKI so sorry if this is the wrong forum for this...

This is very easy with DPL. Just use [[linksto]] with PAGENAME or FULLPAGENAME. Example:<br>

Pages linking to the current page:
 +
{{#dpl:linksto={{FULLPAGENAME}}}}

# Wiki redirects expect a wiki PAGE link not an url.
 +
# So your problem has nothing to do with DPL
 +
# Your Homepage looks nice but the wiki code contains many pieces which are very similar. You should consider to put the DPL statement into a template page (you must use DPL parser function syntax in that case). Maybe also some of your layout-related code could be moved to such a template.

Ok I'll take a look at templates that'd be great to keep our pages to a similar design.
 +
However are you saying there is no way to have a link under my dpl category that directs people to an outside site?
 +
Or is there a way and I'm just missing it?
 +
----
 +
You can always create links to outside URLs as part of normal wiki text or as part of DPL output. But the #REDIRECT does not accept external URLS. You would have to use javascript to create an automatic forwarding. See the source of the following DPL statement:
 +
<dpl>
 +
  noresultsheader=[http://google.com Link to Google coming from DPL output ...]
 +
  category=does not exist
 +
</dpl>

==firstrevisionsince parameter==

I'm using the DPL parameter "firstrevisionsince=''dateandoptionaltime''" , to display articles after 20080430.  One results is as follows:  23:57, 2 May 2008 : Insurance Programs . . JSmith    --- I would like for the end result to be:  Insurance Programs  --Displaying only the article and removing the timestamp and the editor's name.  How can I turn the timestamp/editor results off?

I need a little query, which lists all images used by a given article. It would be such simple ...:
 +
<pre>
 +
{{#dpl:
 +
|namespace=image
 +
|linksfrom={{FULLPAGENAME}}
 +
}}
 +
</pre>
 +
... if <code>linksfrom</code> would list links to image-pages, but it doesn't :-(<br>Any idea? Sorry for my lack of English ... --[[User:WiMu|WiMu]] 11:54, 30 April 2008 (CEST)

There was a similar request recently which lead to the new command <tt>[[imageused]]</tt>. But this works the other way round: it finds all articles which contain a certain image. See [[Issue:Imagelinks criteria]].

Maybe you can extend the code in a similar way? Upload an enhanced version of the source and I will test, document and publish it as part of the next release .. [[User:Gero|Gero]] 12:19, 30 April 2008 (CEST)

:Thanks for the quick reply. I already know the <code>imageused</code>-function; well ... I could do something like this:

== Weird query ==

 +
Hey,
 +
I would like to make weird query in DPL. I've got page named "FOO" and it has ie. 4 sections. On the other page I want DPL to show '''name of the USER''' who was the last editor of "FOO" page (last edited section). I would like also DPL displays TITLE of this section and last revision DATE of this article.
 +
I know I can display title of this page, last user (addlasteditor) and date (addeditdate), but I don't know if there is possibility to show last edited section.

== Question about dominantsection ==
 +
 
 +
Do you think you can help me with a question about dominate section? I have an artical structure like so:
 +
 
 +
 
 +
'''Page to pull DPL data From'''
 +
* Overview
 +
* Component 1
 +
** Goal
 +
** Issues
 +
* Component 2
 +
** Goal
 +
** Issues
 +
 
 +
 
 +
By default DPL will place all the '''Goal''' text (from Component 1 and Component 2) in one cell in the Goal column of the sortable table. If I use ''dominatesection=3'' I can get DPL to not combine Goal of Component 1 to Goal of Component 2, but unfortunately it keeps the information on the same table row so it just keeps extending out to the right. Is it possible to put Component 2 information on a second row of the dynamic table? Thanks for the help and the great extension.

 +
==allrevisionssince==

How do I get the allrevisionssince parameter to work?  Do I place the parameter within <DPL></DPL> within a wiki text? Or do I need to change a php setting within a file in my wiki?

== Showing a tag with DPL variables ==

 +
Hi, it seems that DPL variables don't work in a tag.
 +
 
 +
The tag i use is from [http://www.mediawiki.org/wiki/Extension:CommunityVoice Extension:CommunityVoice]  :<BR>
 +
<nowiki>{{#tag:ratings:scale||category=""|title=ABC}}</nowiki>
 +
 
 +
It's supposed to output : <BR>
 +
<nowiki><div id="cv_ratings_scale__ABC class="communityvoice-ratings-scale"> .....</div></nowiki>
 +
 
 +
However, when using it with %TITLE% variable in DPL, %...% seems to cause a bug. The result becomes :<BR>
 +
<nowiki>
 +
<div id="cv_ratings_scale__TITLE class="communityvoice-ratings-scale"> .....</div></nowiki>
 +
 
 +
Using it with %PAGE%, it outputs:<BR>
 +
<nowiki><div id="cv_ratings_scale__PAGE" class="communityvoice-ratings-scale"> .....</div></nowiki>
 +

Do not include template content on dpl list

Err... Why not create the FAQ using a DPL?

Each FAQ goes into a separate page, and the DPL lists them all. I actually tried this on my own site... the problem was that I wanted to create a TOC to list the questions at the top of the page, so I did something like "==%TITLE%==", however, the TOC appeared to be inside the DPL!

This was a problem because I wanted to split the FAQ into sections like Technical questions and General questions, which is naturally acheived by subcategories of the FAQ category, then I used a separate DPL for each subcategory. This messed up because ... er TOC was messy? I gave up in the end.

Just thought though! --Dmb 22:16, 15 September 2007 (CEST)

Further, the articles would be sorted by hits... FAQ baby! This would be displayed on a page with a 'create an answer' inputbox. I dare you to say it should not be so! (Make it so?) --Dmb 22:18, 15 September 2007 (CEST)


I'm trying to work on this website
http://www.collaborativelandscape.org/wiki/ARCH_728_2007
We are using DPL to make categories.
If you'll look under Department/University Resources there are two pages,
NDSU Homepage and Architectural Department Homepage that I want to actually link to external pages.
NDSU Homepage needs to direct people to www.ndsu.edu

I've tried creating a page called NDSU_Homepage and then from there redirecting people to http://www.ndsu.edu but that doesn't work for some reason it just leaves me at the redirect page.

My category code looks like: <br> |align="left" width="33%" style="background-color:#FFFFFF; border-top:1px solid #808080; border-bottom:1px solid #808080;padding-top:10px; padding-right:10px; padding-left:0px; padding-bottom:10px;" valign="top"| <h2 style="margin:0;background:#f3f3f3;font-family:sans-serif;font-size:120%;font-weight:bold;border:1px solid #808080;text-align:left;color:#000;padding-left:0.4em;padding-top: 0.2em;padding-bottom:0.2em;">'''[[:Category:Department/University Resources|Department/University Resources]]'''</h2>

<DPL>
category=Department/University Resources
ordermethod=title
order=ascending
redirects=include
count=10
</DPL>

My redirect page looks like:
#REDIRECT [http://www.ndsu.edu]
[[Category:Department/University Resources]]
Do you have any suggestions? Thanks

  1. Wiki redirects expect a wiki PAGE link not an url.
  2. So your problem has nothing to do with DPL
