Fort the special sorting, in my config :
# sorting pages by numerical integer pagetextvar data
function IntegerDataCompare($x, $y, $var) {
# get integer value of the page text variable
$xval = intval(PageTextVar($x, $var));
$yval = intval(PageTextVar($y, $var));
# compare integer values
if($xval > $yval) $c = 1;
elseif($xval < $yval) $c = -1;
else $c = 0;
return $c;
}
$PageListSortCmp['registre_origine'] = 'IntegerDataCompare($x, $y,
"registre_origine")';
My pagelist :
(:pagelist group=Bob link=Source.2048 $:registre_origine=-
fmt=#registre order=registre_origine:)
Strangely, it's half working, half broken : data are ordered, but it
looks like the list is splitted : I get something like this, (where x
appears as if it were empty) : 10 10 10 9 9 8 8 7 7 6 6 5 5 4 4 3 x 10
10 9 9 (etc., list continues, broken several times by an empty value).
Thanks for your message and for letting me test your wiki -- it
uncovered an issue I haven't contemplated.
This error in sorting is caused by the large number of calls to the core
function PageTextVar(). When that happens, you quickly hit the
$MaxPageTextVars limits which are set to prevent infinite loops like
these:
Var1: {$:Var2}
Var2: {$:Var1}
Obviously, in a pagelist sorting we don't risk an infinite loop, but a
variable of a page will be compared hundreds of times to the same
variable on hundreds of other pages.
I have updated the custom pagelist sort functions documented in the
Cookbook to directly use the "cached" variables instead of calling
PageTextVar() every time:
http://www.pmwiki.org/wiki/Cookbook/CustomPagelistSortOrderFunctions
I'll think about maybe adding a switch in the core to temporarily ignore
$MaxPageTextVars from a custom local function. But for now use the
helper function I wrote at the above page.
