Fatal error when attempting to sort by…

    The page sort using Feedzy widget and shortcode is not correct. Some items at the top are older and it is just very mixed.

    I really just want to understand how this worked in order to implement a better sort function, so I attempted to place the following in my theme’s function file:

    function feedzy_alphabetical_sort( $a, $b ){
    return strcmp( $a->get_title(), $b->get_title() );
}
 
function feedzy_items_title_sort( $items, $feedURL ){
    return usort( $items, 'feedzy_alphabetical_sort' );
}
add_filter( 'feedzy_feed_items', 'feedzy_items_title_sort', 9, 2 );

    …which seems to always to lead the following error on any page with the shortcode or widget:
    Fatal error: Call to a member function get_permalink() on a non-object in /home/content/43/10470443/html/blog/wp-content/plugins/feedzy-rss-feeds/includes/abstract/feedzy-rss-feeds-admin-abstract.php on line 495.

    Note, I did not touch any file but the function file. When I remove the code, the website returns to normal functionality.

    My server is running PHP version 5.3.24 and MySQL version 5.5.43.

    After some tinkering, I got the error to go away, and figured it out… I think.

    I’m no coder, but here is the code that I am using:

    function feedzy_date_sort( $a, $b ){
     if( ($a->get_date()) == ($b->get_date()) ) {
	return 0;
     }
     if (is_a($a->get_date(), 'DateTime')) {
	return ( ($a->get_date()) < ($b->get_date()) ) ? 1 : -1;
      } else {
	return ( strtotime($a->get_date()) < strtotime($b->get_date()) ) ? 1 : -1;
      }
}
 
function feedzy_items_title_sort( $items, $feedURL){ 
    {
        usort( $items, 'feedzy_date_sort' );
    }
    return $items;
}
add_filter( 'feedzy_feed_items', 'feedzy_items_title_sort', 10, 2 );

    Feedback is appreciated!

    Hey @addiprimus

    Can you tell me what is exactly the sorting criteria you would like to use ? By title alph, dates, etc ?

    Thanks !
