Filtering a loop with taxonomy field

I have a PAGE where i want to show articles that fit to this page. i use a taxonomy custom field to list the news-categorys. With this code i can show links to the assigned taxonomy:

<?php 
    $terms = get_field('newskategorie');
    if( $terms ): ?>
    <ul>
    <?php foreach( $terms as $term ): ?>
    <?php echo $term->name; ?>
    <?php endforeach; ?>
    </ul>
    <?php endif; ?>

Now i wonder how it is possbible to show just lists to articles in the same taxonomy?

E.g. i have the page “Tomatos” and i want to shows news (title + excerpt) from the category “red” and “vegetables” – not just links to the archive pages …

Hi @herrfischer

Hmm… I believe you should be able to accomplish this using a tax_query in WP_Query. For example, the following code will query posts that are in the red and vegetable category:

$args = array(
	'post_type' => 'post',
	'tax_query' => array(
	array(
		'taxonomy' => 'category',
		'field'    => 'slug',
		'terms'    => array('red', 'vegetables')
	),
	),
);
$query = new WP_Query( $args );

For more information, have a look at: https://codex.wordpress.org/Class_Reference/WP_Query#Taxonomy_Parameters

Hope this helps 🙂
