Paginator displays a horizontal UI menu providing links to pages when all of the content does not fit on a page. Paginator is a stand-alone component but you can use it in conjunction with other compononents.
Adding and Using¶
Place paginator in a designated spot on your page. You also should specify what’s the total number of pages paginator should have:
$paginator = $layout->add('Paginator'); $paginator->total = 20;
Paginator will not display links to all the 20 pages, instead it will show first, last, current page and few
pages around the current page. Paginator will automatically place links back to your current page through
After initializing paginator you can use it’s properties to determine current page. Quite often you’ll need to display current page BEFORE the paginator on your page:
$h = $page->add('Header'); $page->add('LoremIpsum'); // some content here $p = $page->add('Paginator'); $h->set('Page '.$p->page.' from '.$p->total);
Remember that values of ‘page’ and ‘total’ are integers, so you may need to do type-casting:
$label->set($p->page); // will not work $label->set((string)$p->page); // works fine
Range and Logic¶
You can configure Paginator through properties.
Reasonable values for $range would be 2 to 5, depending on how big you want your paganiator to appear. Provided that you have enough pages, user should see $range*2+1 bars.
You can override this method to implement a different logic for calculating which page links to display given the current and total pages.
Returns number of current page.
Paginator uses Semantic UI ui pagination menu so if you are unhappy with the styling (e.g: active element is not sufficiently highlighted), you should refer to Semantic UI or use alternative theme.
The template for Paginator uses custom logic:
- rows region will be populated with list of page items
- Item region will be cloned and used to represent a regular page
- Spacer region will be used to represent ‘...’
- FirstItem if present, will be used for link to page “1”. Otherwise Item is used.
- LastItem if present, shows the link to last page. Otherwise Item is used.
Each of the above (except Spacer) may have active, link and page tags.
Specifying a view here will cause paginator to only reload this particular component and not all the page entirely.
Usually the View you specify here should also contain the paginator as well as possibly other components that
may be related to it. This technique is used by
Grid and some other components.
