getPage - How to link to item on page X?

Hi there,

I have an unordered list of items that are rendered to the page using getPage. The items are displayed in a number of pages with pagination and that all works great. Now what I'd like to be able to do is link to the page that this list is on, passing a param like ?itemid=12 and then when the paged content loads, go to the pagination page that the item is on and select it.

I'm relatively new with Modx so my apologies if a solution to this issue exists already. The forums are great but I find searching them diffucult as there's no easy way to return results just for a certain topic or more importantly just for Revolution (or is there and I just don't know how).

Any help would be greatly appreciated. I'm running latest ver of Revolution and latest version of getPage.

Thanks in advance!

something like that should work:

create a snippet 'getpaginationmap'

<?php

$limit=$scriptProperties['limit'];
$scriptProperties['limit'] = '0';
$scriptProperties['tpl'] = '@INLINE [[+id]]';
$scriptProperties['outputSeparator'] = ',';

$result = $modx->runSnippet('getResources',$scriptProperties);

$resids = explode(',',$result);

$page = 1;
$counter = 1;
foreach ($resids as $resid){
    $paginationmap[$resid]=$page;

    if ($counter == $limit){
        $counter = 1;
        $page ++;
    }    
    $counter ++;
}
return $modx->toJson($paginationmap);

and another snippet which redirects to the paginated page 'redirectToPage':

<?php

$paginationmap = $modx->fromJson($paginationmap);

if (isset($_REQUEST['itemid'])){
    $page = $paginationmap[$_REQUEST['itemid']];
    $modx->sendRedirect($modx->makeUrl($redirectTo,'','&page='.$page.'&item='.$_REQUEST['itemid']));
}

call it the same way as you call your getPage-snippet.

[[!redirectToPage? 
&redirectTo=`2` 
&paginationmap=`[[getpaginationmap? &limit=`2` &parents=`11,10`]]`]]
