Question

I want to display all posts of a post format (let’s say: aside). In WordPress to display all posts of a certain category, just need to use this URL: mysite.com/category/mycategory. Is there a similar way to display all posts of a post format? Or any other way is also fine for me.

Answer 1

You could use tax_query parameters to get the posts by post_format. For example:

$args = array(
    'post_type'=> 'post',
    'post_status' => 'publish',
    'order' => 'DESC',
    'tax_query' => array(
        array(
            'taxonomy' => 'post_format',
            'field' => 'slug',
            'terms' => array( 'post-format-aside' )
        )
    )
);

Then you can iterate over the results with get_posts() (or use WP_Query() and a standard a Loop):

$asides = get_posts( $args );
if ( count($asides) ) {
    foreach ( $asides as $aside ) {
        // do something here...
    }
}
