Show a pager for search results.

This generates a pager as seen on the search results pages. It is used in conjunction with a paged search result.

For example, a fulltext search where the search parameters come from the query string:

{% with[{fulltext cat=q.qcat text=q.qs pagelen=20}] as result %}
    {% pager result=result dispatch="admin_overview_rsc" qargs %}
    {% for id,score in result %}
      <li><a href="">{{ m.rsc[id].title }}</a></li>
    {% empty %}
      <li>Nothing found</li>
    {% endfor %}
{% endwith %}

This will show a list of titles and above that the links to the next, previous and other pages.

The generated pager code will look something like (when searching for the text “filter”):

<ul class="pager block">
<li>« prev</li>
<li class="current"><a href="/admin/overview?qs=filter&page=1">1</a></li>
<li><a href="/admin/overview?qs=filter&page=2">2</a></li>
<li><a href="/admin/overview?qs=filter&page=3">3</a></li>
<li><a href="/admin/overview?qs=filter&page=4">4</a></li>
<li class="pager-sep">…</li>
<li><a href="/admin/overview?qs=filter&page=5">5</a></li>
<li><a href="/admin/overview?qs=filter&page=2">next»</a></li>

The pager tag accepts the following arguments:

Argument Description Example
result The result from a search. This must be a #search_result or a list. Note that the records should be the result of a and not of a call. result=mysearchresult
dispatch Name of the dispatch rule to be used for the page urls. Defaults to the dispatch rule of the current page. dispatch=”searchresult”
qargs Append all the arguments in the HTTP request’s query string whose name starts with a ‘q’ as an argument to the dispatch rule. qargs
hide_single_page When this argument is true, do not show the pager when the result fits on one page (e.g. the pager will be useless). hide_single_page=1
template Name of the template for rendering the pager. Defaults to _pager.tpl. See below for specific arguments passed. template=”_pager.tpl”
page Current page number, the first page is page number 1. Fetched from the search result, this argument, or page=2
pagelen Number of items per page, fetch from the search result or q.pagelen. Defaults to 20. pagelen=10
* Any other argument is used as an argument for the dispatch rule.  

Pager template

The pager is rendered using a template. The default template for the pager is _pager.tpl.

The pager template receives the following variables:

  • prev_url The url to the previous page, undefined if at first page.
  • next_url The url to the next page, undefined if at last page.
  • pages A list of tuples. Either {PageNumber, Url} or {undefined, sep} (sep is an atom).
  • page The current page number
  • All other arguments passed to the scomp (attention: these are also used as dispatch arguments)

The default _pager.tpl displays an ellipsis for the sep entry.

If the result set is empty then the template is not rendered. The template is also not rendered if there is a single page and hide_single_page is set.

Result argument

It is also possible to pass a list, a #rsc_list{ list=Ids } record, or a list of lists (pages) for the resut. In this case you need to perform the pagination for displaying the results yourself. You can use the chunk for this. The pager scomp will fetch the page and pagelen from the pager arguments, or from the query arguments (if any). If the list is pre-chunked then the pages does not need the pagelen argument.
