URL rewriting with custom user meta “/%shop_name%/gallery/%gallery%”

I used the following functions to solve this problem. //This adds a custom query variable to the permalink function add_custom_query_var( $vars ){ $vars[] = “shop_name”; return $vars; } add_filter( ‘query_vars’, ‘add_custom_query_var’ ); function add_rewrite_rules($aRules) { $aNewRules = array(‘shop/([^/]+)/?$’ => ‘index.php?pagename=shop&shop_name=$matches[1]’); $aNewRules2 = array(‘shop/([^/]+)/gallery/?$’ => ‘index.php?post_type=gallery’); $aRules = $aNewRules + $aNewRules2 + $aRules; return $aRules; } … Read more

Making extra parameters optional

Two points: Your rule isn’t particularly specific. For numeric matches you should be specific about it and specify a) digits and b) how many digits. Year would be ([0-9]{4}), month/day would be ([0-9]{1,2}). You can’t do it with one rule. Add three separate rules instead. add_rewrite_rule( ‘whats-on/([0-9]{4})/?$’, ‘index.php?page_id=71&event_year=$matches[1]’,’top’); add_rewrite_rule( ‘whats-on/([0-9]{4})/([0-9]{1,2})/?$’, ‘index.php?page_id=71&event_year=$matches[1]&event_month=$matches[2]’,’top’); add_rewrite_rule( ‘whats-on/([0-9]{4})/([0-9]{1,2})/([0-9]{1,2})/?$’, ‘index.php?page_id=71&event_year=$matches[1]&event_month=$matches[2]&event_day=$matches[3]’,’top’);
