Why does rewrite rule work for page not for custom post type post?

by

Well, I found the solution. It seems that, when applying a rewrite rule on a custom post type post, one needs to tell WP the custom post type’s name within the rewrite rule itself. Here’s the code that does NOT work (redirects and drops parameter variables instead of rewrite): function add_rewrite_rules($rules) { $newrules = array(‘cpt-slug/([^/]+)/([^/]+)/?$’ … Read more

Making extra parameters optional

by

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’);

Detecting $_GET parameters from any page + Cookie

This should work, though untested. <?php add_action(‘send_headers’, ‘affiliate_redirect’); function affiliate_redirect() { // it’s possible to use ‘if( !empty( $_GET[‘affid’]) )’ if( isset($_GET[‘affid’]) && ” != $_GET[‘affid’] ) { if( empty($_COOKIE[‘affid’]) ) setcookie(‘affid’, $_GET[‘affid’], time()+2592000, “https://wordpress.stackexchange.com/”); header(‘Location: http://mysite.com/about/’); exit; } }

No need for a plugin, You can simply use the Oembed class’s oembed_result filter hook like this: function Oembed_youtube_no_title($html,$url,$args){ $url_string = parse_url($url, PHP_URL_QUERY); parse_str($url_string, $id); if (isset($id[‘v’])) { return ‘<iframe width=”‘.$args[‘width’].'” height=”‘.$args[‘height’].'” src=”http://www.youtube.com/embed/’.$id[‘v’].’?rel=0&showinfo=0″ frameborder=”0″ allowfullscreen></iframe>’; } return $html; } add_filter(‘oembed_result’,’Oembed_youtube_no_title’,10,3); so just paste this code in your theme’s functions.php file, setup the width and height … Read more

CPT archive 404ing when using a custom taxonomy name as a variable

by

I had the same problem on my large project that I currently work on. It’s case when you have collision between taxonomy and post-type slugs. Problem is that you can filter by taxonomy with adding ?taxonomy_name=term_slug and also you can see the custom post by adding ?post_type=custom_post_slug. So, that’s the same syntax, and WP doesn’t … Read more

Why does WordPress automatically redirect URLs with the parameter “name=” to a different page?
