我的2个自定义rss源有以下代码：

add_action( \'init\', \'custom_feeds\' );
function custom_feeds()
{
    foreach( array( \'custom1\', \'custom2\' ) as $name )
    {
        add_feed( $name, 
            function() use ( $name )
            {
                get_template_part( \'rss\', $name );  
            }
        );
    }
}

function feedFilter($query) {
    if ($query->is_feed) {
        $query->set(\'cat\', \'7\');
        $query->set(\'posts_per_page\',\'5\');
    }
    return $query;
}
add_filter(\'pre_get_posts\',\'feedFilter\');
