/**

* MarkupPagerNav Module for generating pagination markup
|

*
|
||
* ProcessWire 3.x, Copyright 2023 by Ryan Cramer
|
||
* https://processwire.com
|
||
*
|
||
* #pw-summary Module for generating pagination markup automatically for paginated WireArray types.
|
||
* #pw-var $pager
|
||
* #pw-instantiate $pager = $modules->get('MarkupPagerNav');
|
||
* #pw-summary-options-methods Specific to setting certain options that are typically set automatically. Not necessary to use these unless for a specific purpose.
|
||
*
|
||
* #pw-body =
|
||
* This module can create pagination for a `PageArray` or any other kind of `PaginatedArray` type.
|
||
* Below is an example of creating pagination for a PageArray returned from `$pages->find()`.
|
||
* ~~~~~
|
||
* // $items can be PageArray or any other kind of PaginatedArray type
|
||
* $items = $pages->find("id>0, limit=10"); // replace id>0 with your selector
|
||
* if($items->count()) {
|
||
* $pager = $modules->get("MarkupPagerNav");
|
||
* echo "<ul>" . $items->each("<li>{title}</li>") . "</ul>";
|
||
* echo $pager->render($items); // render the pagination navigation
|
||
* } else {
|
||
* echo "<p>Sorry there were no items found</p>";
|
||
* }
|
||
* ~~~~~
|
||
* Here’s a shortcut alternative that you can use for PageArray types (thanks to the `MarkupPageArray` module).
|
||
* Note that in this case, it’s not necessary to load the MarkupPagerNav module yourself:
|
||
* ~~~~~
|
||
* $items = $pages->find("id>0, limit=10"); // replace id>0 with your selector
|
||
* if($items->count()) {
|
||
* echo "<ul>" . $items->each("<li>{title}</li>") . "</ul>";
|
||
* echo $items->renderPager(); // render the pagination navigation
|
||
* } else {
|
||
* echo "<p>Sorry there were no items found</p>";
|
||
* }
|
||
* ~~~~~
|
||
* It’s common to specify different markup and/or classes specific to the need when rendering
|
||
* pagination. This is done by providing an `$options` array to the `MarkupPagerNav::render()` call.
|
||
* In the example below, we'll specify Uikit markup rather then the default markup:
|
||
* ~~~~~
|
||
* // Change options for Uikit "uk-pagination" navigation
|
||
* $options = array(
|
||
* 'numPageLinks' => 5,
|
||
* 'listClass' => 'uk-pagination',
|
||
* 'linkMarkup' => "<a href='{url}'>{out}</a>",
|
||
* 'currentItemClass' => 'uk-active',
|
||
* 'separatorItemLabel' => '<span>…</span>',
|
||
* 'separatorItemClass' => 'uk-disabled',
|
||
* 'currentLinkMarkup' => "<span>{out}</span>"
|
||
* 'nextItemLabel' => '<i class="uk-icon-angle-double-right"></i>',
|
||
* 'previousItemLabel' => '<i class="uk-icon-angle-double-left"></i>',
|
||
* 'nextItemClass' => '', // blank out classes irrelevant to Uikit
|
||
* 'previousItemClass' => '',
|
||
* 'lastItemClass' => '',
|
||
* );
|
||
*
|
||
* $items = $pages->find("id>0, limit=10"); // replace id>0 with your selector
|
||
*
|
||
* if($items->count()) {
|
||
* $pager = $modules->get('MarkupPagerNav');
|
||
* echo "<ul>" . $items->each("<li>{title}</li>") . "</ul>";
|
||
* echo $pager->render($items, $options); // provide the $options array
|
||
* } else {
|
||
* echo "<p>Sorry there were no items found</p>";
|
||
* }
|
||
* ~~~~~
|
||
* The full list of options can be seen below. Please note that most options are set automatically since this module can
|
||
* determine most of the needed information directly from the WireArray that it’s given. As a result, it’s often
|
||
* not necessary to change any of the default options unless you want to change the markup and/or classes used in output.
