[pmwiki-users] pagelist order=month?

[Peter Bowers]

Here's a quick shot at modifying the examples on that page...

On the wiki page:
(:pagelist order=yearmonthday:)

In your config.php:

$PageListSortCmp['yearmonthday'] = 'YearMonthDayComp($x, $y)';
$Months = array ('jan'=>1, 'feb'=>2, ..., 'dec'=>12);

function YearMonthDayComp($x, $y) {
      ## compare the $:Year values
      $c = strcmp(PageVar($x, '$:Year'), PageVar($y, '$:Year'));
      if ($c != 0) return $c;

      ## compare the $:Month values
      $c = $Months[strtolower(PageVar($x, '$:Month'))] -
$Months[strtolower(PageVar($y, '$:Month'))]
      if ($c != 0) return $c;

      ## compare the $:Day values
      $c = intval(PageVar($x, '$:Day')) - intval(PageVar($y, '$:Day')));
      return $c;
}

Note that I'm not sure whether I should be subtracting y from x (as
I've done) or x from y for the month and day comparison.

Note also that I'm assuming you've got exactly 4 digits for years and
that they are entered consistently.  If the month is misspelled or
something then undesired results will occur without any error messages
(or perhaps ugly PHP error messages), etc.
