Previous / Next Item Links from Detail View

Add links to the previous and next module items from an items detail page.

v1.0.0

  1. Encourage user exploration and time-on-site by providing ‘Previous’ and ‘Next’ links to related/sequential items when a single item is being viewed, such as blog posts, products, events and more.

    The sort order from your module component will determine the sequence of items to progress to. So, this can be controlled by the sortBy and sortOrder parameters.

    Any item data can be rendered for the previous and next items simply by using and respectively.

{% component source: "Your Module Name", layout: "", sortBy: "ReleaseDate", sortOrder: "DESC", limit: "100", enablePagination: "true", collectionVariable: "itemList", type: "module" %}

{% for i in itemList.items %}
{% if request.request_url.path == i.url %}
    {% assign listIndex = forloop.index0 %}
    {% assign listIndexPrev = listIndex | minus: 1 %}
    {% assign listIndexNext = listIndex | plus: 1 %}
    {% break %}
{% endif %}
{% endfor %}

{% if listIndexPrev >= 0 %}
    <a href="{{itemList.items[listIndexPrev].url}}">{{itemList.items[listIndexPrev].name}}</a>
{% endif %}
{% if listIndexNext < itemList.Pagination.TotalItemsCount %}
    <a href="{{itemList.items[listIndexNext].url}}">{{itemList.items[listIndexNext].name}}</a>
