Getting Offset with getImageList & getPage

clutchmarketing · September 2, 2021, 5:34pm

I am having a problem where the offset parameter doesn’t work when used with getImageList and getPage together. Here is my call.
[[!getPage?
&element=getImageList
&docid=30
&tvname=mytv
&limit=9
&tpl=mytpl
&offset=1
]]

The offset paramete works fine directly with getImageList but not when used with getPage for pagination.

The snippet getPage calculates the value for the property offset itself (from the current page and the value of limit) to provide it to the snippet getImageList.

$properties =& $scriptProperties;
          $properties['page'] = (isset($_GET[$properties['pageVarKey']]) && ($page = intval($_GET[$properties['pageVarKey']]))) ? $page : null;
          if ($properties['page'] === null) {
              $properties['page'] = (isset($_REQUEST[$properties['pageVarKey']]) && ($page = intval($_REQUEST[$properties['pageVarKey']]))) ? $page : 1;
          }
          $properties['limit'] = (isset($_GET['limit'])) ? intval($_GET['limit']) : null;
          if ($properties['limit'] === null) {
              $properties['limit'] = (isset($_REQUEST['limit'])) ? intval($_REQUEST['limit']) : intval($limit);
          }
          $properties['offset'] = (!empty($properties['limit']) && !empty($properties['page'])) ? ($properties['limit'] * ($properties['page'] - 1)) : 0;
          $properties['totalVar'] = empty($totalVar) ? "total" : $totalVar;
          $properties[$properties['totalVar']] = !empty($properties[$properties['totalVar']]) && $total = intval($properties[$properties['totalVar']]) ? $total : 0;
          $properties['pageOneLimit'] = (!empty($pageOneLimit) && $pageOneLimit = intval($pageOneLimit)) ? $pageOneLimit : $properties['limit'];
          $properties['actualLimit'] = $properties['limit'];
          $properties['pageLimit'] = isset($pageLimit) && is_numeric($pageLimit) ? intval($pageLimit) : 5;
          $properties['element'] = empty($element) ? '' : $element;
          $properties['elementClass'] = empty($elementClass) ? 'modChunk' : $elementClass;
          $properties['pageNavVar'] = empty($pageNavVar) ? 'page.nav' : $pageNavVar;
          $properties['pageNavTpl'] = !isset($pageNavTpl) ? "<li[[+classes]]><a[[+classes]][[+title]] href=\"[[+href]]\">[[+pageNo]]</a></li>" : $pageNavTpl;
          $properties['pageNavOuterTpl'] = !isset($pageNavOuterTpl) ? "[[+first]][[+prev]][[+pages]][[+next]][[+last]]" : $pageNavOuterTpl;

So whatever you define for offset in your call to getPage gets overwritten.

You’ll probably have to duplicate the getPage snippet and make some changes to the code to make it work.
