[Support request] Showing posts from a tag?

Hi Ema,

Hello! is there a way that I can show posts from a Category that spans all 4 of my CPTs?

It should be possible but we’ll have to resort to a bit of modification to the plugin’s file and a bit more custom PHP for filtering the query.

Make this change in your wp-show-posts.php file: https://github.com/tomusborne/wp-show-posts/commit/286caf1164db8b6b6f38b85d3a011b519a27f4de

The PHP will be something like this:

add_filter( 'wp_show_posts_shortcode_args', function( $args, $settings ) {
    if ( 123 === $settings['list_id'] ) {
        $args['post_type'] = array('post','custom_post_type_slug_1','custom_post_type_slug_2','custom_post_type_slug_3');
        $args['tax_query'] = array(
			'relation' => 'OR',
			array(
				'taxonomy' => 'topics',
				'field'    => 'slug',
				'terms'    => array( 'featured','another-topic-term' ),
			)
    	);
    }

    return $args;
} );

Change 123 to the WPSP list ID you’re displaying this on and change $args['post_type'] = array('post','custom_post_type_slug_1','custom_post_type_slug_2','custom_post_type_slug_3'); to add the post type slugs.

You’ll also have to change 'terms' => array( 'featured','another-topic-term' ), array slugs to featured + other “Topics” term slugs you want to include. 😀
