<?php if ($this->previousArticle): ?>
    <a href="{{news_url::<?= $this->previousArticle ?>}}" class="previous">
        <?= $this->previousArticleLabel ?>
    </a>
<?php endif; ?>

Newsarchives

To let the navigation respect only news archives set in NewsReaderModule, you find an option in the module backend.

Developers

Template variables

This extension adds following template tags to the news template model, which you can use in your templates:

name description
nextArticle Next (newer) article id
previousArticle Previous (older) article id
nextArticleLabel Next article label ("Next article")
previousArticleLabel Previous article label ("Previous article")

If you want the news title instead the next/previous article label, see #1 how to do this.

Custom filters

The module allow a simple mechanic to add custom filters for the news navigation. You need to set additional filters to the huh.newsnavigation.newsfilter before the parseArticles Hook (from this module) of the NewsReaderModel is called. You can use following methods:

Examples:

// add additional database conditions
System::getContainer()->get('huh.newsnavigation.newsfilter')->addFilter('tl_news.newsCategory=?', 'contao4bundles');
// add additions options
System::getContainer()->get('huh.newsnavigation.newsfilter')->setOption('limit', '5');

Custom filter use

You can use the filter in custom way:

$filter = System::getContainer()->get('huh.newsnavigation.newsfilter');

// Creates a new filter object which contains all filters
$newFilter = $filter->createCopy();

// Create a new empty newsfilter instance
$newFilter = new HeimrichHannot\NewsNavigationBundle\NewsFilter\NewsFilter();

// Return the filter rules
$filter->getColumns()
$filter->getValues()
$filter->getOptions()

// Override filter rules
$filter->setColumns();
$filter->setValues();
$filter->setOptions();

// Change or return model
$filter->setModel();
$filter->getModel();
