Link to specific page in archive with pagination

[verdeandrea]

Hi guys,

i have a news archive, where i cycle through a lot of pages and this cycle is paginated.

In my home page i need to link to a specific news, but not directly to its page, but to the archive page containing this news.

So if, for example, i have e news in page 3 of my archive, i would like to link to this page.

The question is, what is the best way to get the link to the right page of my archive?

Thank you

I'm not sure if there's really a better way to do this, without potential for breakage.

$pageNum = 1;
$limit = 20;
$start = $pageNum - 1 * $limit;
$base = "template=news, id=$mySearchedPage->id";

while($pages->count($base . ", start=$start")){
  $count = $pages->count($base . ", limit=$limit, start=$start");
  if($count) break;
  $pageNum++;
  $start = $pageNum - 1 * $limit;
}

Another solution

// number of news per news page
$limit = 20;

// get all news
$allNews = $pages->find("template=news");

// get the specific news item
$selector =  // selectorstring to get specific news item
$specificNews = $allNews->get($selector);

// get the page number where to find the specific news item
$key = $allNews->getItemKey($specificNews);
$pageNum = ceil($key/ $limit);
