You must create valid syntax for the gallery extension if you want to use it within DPL; add debug=5 at the beginning of your statement and check what the Template Template:Infobox Country or territory dpl produces. Gero 10:34, 4 April 2008 (CEST)

{{#arraydefine:x|

follow the link in the headline .. ° In the standard configuration DPL registers the <DynamicPageList> tag. This is needed to be downward compatible with extension 'Intersection'.

In the transition phase you may want to install DPL in PARALLEL to 'Intersection' for testing. DPL offers a second entry point for that purpose. Instead of require_once("DynamicPageList.php") you have to use require_once("DPLMigration.php"). DPL will then ONLY register a tag called <Intersection>

In this constellation you can change some of your existing calls of 'Intersection' (which use the <DynamicPageList> tag) to the <Intersection> tag. Once you are convinced that this produces identical results and works with equal efficiency you can change to require_once("DynamicPageList.php"). Don't forget to change the statements back to the <DynamicPageList> tag!. Of course you must also remove the require_once() for the Intersection extension. ° The general approach to output formatting is two-fold:

  1. There are a couple of simple predefined output formats which generate lists of articles
    You will understand their meaning directly from reading
  2. There is a mode called "userformat" which puts complete control into your hands
    This is somewhat complicated.

While the standard output formats are meant to be used for fast generation of simple page lists, the userformat approach aims at transcluding contents from other pages and requires some effort to understand. There is a system of three tags which are used to enclose (a) the whole output, (b) each item, (c) each transcluded section of an item. A fourth tag is used to separate values between items of one section which occur more than once.

We assume that we have two documents which use templates x and y with varying arguments; while x is being used once within each document, y is used several times. In very short notation the structure might look as follows: 

A: x(a) y(3) y(5)
B: x(b) y(4) y(1) y(2)

The following DPL parameters are used to define a set of tags which are used to construct the output:

The arguments of the above statements can contain references to %VARIABLES%. So sec-1-start might contain a reference like %PAGE% to output the page name. See format for more details on variable substitution.

Now think of the following page inclusion statement: 

 includepage={x}.dpl,{y}.dpl

The output will then look like this: 

 liststart
    itemstart
       sec-1-start
          x.dpl(a)
       sec-1-end
       sec-2-start
          y.dpl(3)
          multi-sep
          y.dpl(5)
       sec-2-end
    itemend
    itemstart
       sec-1-start
          x.dpl(b)
       sec-1-end
       sec-2-start
          y.dpl(4)
          multi-sep
          y.dpl(1)
          multi-sep
          y.dpl(2)
       sec-2-end
    itemend
 listend

Assuming that the tags (liststart, itemstart, etc.) contain wiki syntax for table definitions and multi-sep defines a horizontal line, the output might look like this: 

 +------+---------------------+
 |      |          | y.dpl(3) |
 |  A   | x.dpl(a) |  ----    |
 |      |          | y.dpl(5) |
 +------+----------+----------+
 |      |          | y.dpl(4) |
 |      |          |  ----    |
 |  B   | x.dpl(b) | y.dpl(1) |
 |      |          |  ----    |
 |      |          | y.dpl(2) |
 +------+----------+----------+

In some situations, however, you may want to create an output table where each of the calls of template y is used to create a separate output row. Using a sortable table you could then easily rearrange the output. 

 +------+---------------------+       +------+---------------------+
 |  A   | x.dpl(a) | y.dpl(1) |       |  B   | x.dpl(b) | y.dpl(1) |
 +------+---------------------+       +------+---------------------+
 |  A   | x.dpl(a) | y.dpl(2) |       |  B   | x.dpl(b) | y.dpl(2) |
 +------+---------------------+       +------+---------------------+
 |  B   | x.dpl(b) | y.dpl(3) |       |  A   | x.dpl(a) | y.dpl(3) |
 +------+---------------------+       +------+---------------------+
 |  B   | x.dpl(b) | y.dpl(4) |       |  A   | x.dpl(a) | y.dpl(4) |
 +------+---------------------+       +------+---------------------+
 |  B   | x.dpl(b) | y.dpl(5  |       |  B   | x.dpl(b) | y.dpl(5) |
 +------+---------------------+       +------+---------------------+

There is a special parameter called dominantsection which you can use to mark one section of your includepage statement as "dominant" (in our example: dominatsection=2 as {y}.dpl is the second argument of our includepage statement). You can only have one dominant section in a DPL statement. Marking a section as "dominant" only makes sense if you have multiple calls of the same template (or multiple chapters with the same heading) in your documents. Each piece of content in the dominant section will generate an individual output row with the values of all other columns being repeated.

As all of the above is not very easy to understand there are additional DPL commands (table, tablerow) which make it fairly easy to create tabular output. °°

updaterules define a set of rules which are executed to perform an update on selected articles (bulk update or template value editing)

Syntax: 

updaterules=
    rule;
    ...
    rule;

Where rule is one of the following:

  • rules for batch update of articles 
   replace   pattern;
      by        replacement;
   before    pattern;
      insert    text;
   after     pattern;
      insert    text;
  • rules for interactive update of articles
   template  template name;
   legend    legend article name;
   table     table format;
   editform  form parameters;
   action    form action;
   hidden    value;
   submit    submit button;
   commit    commit button;
   parameter parameter name;
      value      value;
      format     display format;
      tooltip    text;
      optional   value;
      afterparm  parameter name;
  • common rules
   summary   edit summary text;
   exec      value;

The first group of rules is intended for batch updates of articles. A DPL query can select a group of articles and perform updates like inserting a piece of text at a certain position or changing text portions based on regular expressions.

The second group of rules is intended for interactive form-based editing of template values.

The third group of rules is common to both other groups and controls the update process.

The updaterules feature is intended for wiki expert users only. It is recommended that articles usind this statement are 'protected':

° 

 {{#dplmatrix: name | yes | no | mode | '''indented_list''' }}

° 

  {{#dplnum:text}}

° 

  {{#dplreplace:text|pattern|replacement}}

° 

 (1) {{#dplvar:set    |name1|value1|name2|value2|..|..}}
 (2) {{#dplvar:default|name|value}}
 (3) {{#dplvar:        name}}

° Download the ZIP archive and extract the DynamicPageList subdirectory to a directory named yourwiki/extensions/DynamicPageList. You may ignore the other extensions but it is recommended to install at least Call and Inputbox as some DPL based applications like the DPL GUI use them. °|°}} {{#arraysort:x|random}} {{#arrayindex:x|0}}
