Pagination suggestions

I’m looking for some suggestions on how to best handle pagination based on section and issue#.

The site has 14 articles posted once every second month. Articles are posted to one of three sections (local, national, international). Never the same number of articles posted to any one section with each issue.

We would like the landing page for each section to display a list of all articles posted to that section and sorted by issue number. An example would look something like…

The LOCAL section (url = thesite.com/local/)

ISSUE 49
local-story A
local-story B
local-story C

ISSUE 48
local-story D
local-story E
local-story F
local-story G

ISSUE 47
etc etc etc

The NATIONAL section would look similar… (url = thesite.com/national/)

ISSUE 49
national-story a
nationa-story b
national-story c
national-story d
national-story e

ISSUE 48
national-story f
national-story g
national-story h

The default custom article limits the article count per page to ten. More often than not this breaks up the last issue and puts part of the issue on one page (bottom) and the rest of the issue on the next page (top). We need to determine the number of SECTIONS each page displays… not the number of articles.

We don’t want to use categories as they are being used for an entirely different purpose.

Each article has a custom field to indicate the issue number.

Re: Pagination suggestions

Well don’t ask such difficult questions then… ;)

I’ve been thinking about this, just haven’t come up with a solution so far (and I’m not sure that I ever will…).
Did you create this article list with <txp:if_different>?
And with this:

We need to determine the number of SECTIONS each page displays… not the number of articles.

did you actually mean ‘issues’ instead of ‘sections’?

Re: Pagination suggestions

very rough and ugly pseudo code:

<txp:php>
$pg = intval(gps('pg')); #current page number;
if ($pg > 0) $pg--;
$ipp = 3; #issues per page;
$issues = safe_rows('query returning issue numbers ORDER DESC LIMIT $ipp*$pg, $ipp');
$_GET['pg'] = 0; # forget page number
foreach ($issues as $issue) {
  #loop through the issues we want displayed on this page
  echo article(array('custom_1' => $issue));
}
# try to fix pagination
$itot = safe_count('number of issues');
$atot = safe_count('number of articles');
article(array('pgonly' => 1, 'pageby' => intval($atot/$itot)));
</txp:php>

Page tags
<txp:if_individual_article> <txp:article form="xyz" />

<txp:else />
<dl>
<txp:article sort="(custom_3+0) desc, Posted asc" form="archive_list" />
</dl>
</txp:if_individual_article>

The xyz form
<txp:if_individual_article>

<h1><txp:title /></h1>
<h2><txp:custom_field name="sub_title" /></h2>
<h3 class="sub_title">by ~ <txp:custom_field name="author_name" /></h3>

<txp:body />
</txp:if_individual_article>

Correct. Good call. We need to determine the number of ISSUES each page displays not the number of articles.

I’d rather see the archive_list form if you don’t mind?

Edit: BTW does Ruud’s script do what you want?
