Partials are typically small files containing similar content as your views and layouts, the only difference being that partials are intended to be reusable: whereas a view is always tied to single template, multiple views (and layouts) can use the same partial.
Here's one example of a partial file (/site/templates/partials/menu/breadcrumbs.php):
<?php namespace ProcessWire; ?> <nav aria-label="Breadcrumbs" class="breadcrumbs"> <ul class="breadcrumbs__list"> <?php foreach ($page->parents as $item): ?> <li class="breadcrumbs__list-item"> <a class="breadcrumbs__item" href="<?= $item->url ?>"> <?= $item->title ?> </a> </li> <?php endforeach; ?> <li class="breadcrumbs__list-item"> <span class="breadcrumbs__item breadcrumbs__item--active" tabindex="0" aria-label="Current page: <?= $page->title ?>"> <?= $page->title ?> </span> </li> </ul> </nav>
A partial can be embedded into a view file using PHP's own include or require statements:
<?php include 'partials/menu/breadcrumbs.php';
Note that the /site/templates/ directory is automatically added to PHP's include path, so you can refer to partials with a relative path, such as in the example above. In addition Wireframe provides an alternative, object-oriented way to refer to partials:
<?php include $partials->menu->breadcrumbs;
