Sort Custom Post Type Alphabetically

  • Hi Community

    I’m trying to sort posts within my custom post type alphabetically on a custom field called ‘surname’.

    I’m following the example for functions.php here https://www.advancedcustomfields.com/resources/orde-posts-by-custom-fields/.

    But its not working.

    My custom post type is
    register_post_type('ceramicist'

    The code in functions.php is

    function my_pre_get_posts( $query ) {
    	
    	// do not modify queries in the admin
    	if( is_admin() ) {
    		
    		return $query;
    		
    	}
    	
    
    	// only modify queries for 'ceramicist' post type
    	if( isset($query->query_vars['post_type']) && $query->query_vars['post_type'] == 'ceramicist' ) {
    		
    		$query->set('orderby', 'meta_value');	
    		$query->set('meta_key', 'surname');	 
    		$query->set('order', 'ASC'); 
    		$query->set( 'suppress_filters', 'true' );
    	}
    	
    
    	// return
    	return $query;
    
    }
    

    Am I missing something here or if this looks Ok then perhaps my bespoke theme is preventing it form running correctly.

    Thank you

  • Hmm

    Just installed a child theme on the default 2021 theme and still not alphabetically sorting.
    So appears not to be my bespoke child theme.

  • Noticed I had forgotten to add

    add_action('pre_get_posts', 'my_pre_get_posts');

    But that hasn’t helped either

  • Sorry – yes it has!

    Adding

    add_action('pre_get_posts', 'my_pre_get_posts');

    fixed it.

    How embarrassing.
