Simple snippets

This section contains snippets making EXT:news more awesome which might be useful for your projects as well.

Improved back links

The back link on a detail page is a fixed link to a given page. However it might be that you use multiple list views and want to change the link depending on the given list view.

A nice solution would be to use this JavaScript jQuery snippet:

if ($(".news-backlink-wrap a").length > 0) {
        if(document.referrer.indexOf(window.location.hostname) != -1) {
                $(".news-backlink-wrap a").attr("href","javascript:history.back();").text('Back');
        }
}

Creating links with fluid

Besides the ViewHelper <n:link /> you can also use the ViewHelpers of fluid itself:

<f:link.page pageUid="13" additionalParams="{tx_news_pi1: {controller: 'News',action: 'detail', news:newsItem.uid}}">{newsItem.title}</f:link.page>
<a href="{f:uri.page(pageUid:13,additionalParams:'{tx_news_pi1:{controller:\'News\',action:\'detail\',news:newsItem.uid}}')}">{newsItem.title}</a>

Set n:link target page in fluid

If the detail page should not be set in the plugin or by a category, it can also be set within the template:

<n:link
   newsItem="{newsItem}"
   configuration=“{parameter:settings.somePid}"
   settings="{settings}" title="{newsItem.title}"><f:translate key="more-link"/></n:link>

The setting settings.somePid can e.g. set with plugin.tx_news.settings.somePid=123.

Render category rootline

If you want to show not only the title of a single category which is related to the news item but the complete category rootline use this snippets.

<f:if condition="{category:newsItem.firstCategory}">
        <ul class="category-breadcrumb">
                <f:render section="categoryBreadcrumb" arguments="{category:newsItem.firstCategory}" />
        </ul>
</f:if>

and

<f:section name="categoryBreadcrumb">
        <f:if condition="{category}">
                <f:if condition="{category.parentCategory}">
                        <f:render section="categoryBreadcrumb" arguments="{category:category.parentCategory}" />
                </f:if>
                <li>{category.title}</li>
        </f:if>
</f:section>

Use current content element in the template

If you ever need information from the content element itself, you can use {contentObjectData.header}.

Use current page in the template

If you ever need information from the current page, you can use {pageData.uid}.

Sort tags

If you want to sort the tags of a news item, you can use a custom ViewHelper or EXT:vhs:

<ul>
        <f:for each="{newsItem.tags->v:iterator.sort(order: 'ASC', sortBy: 'title')}" as="tag">
                <li>{tag.title}</li>
        </f:for>
</ul>
