You don’t need anything WordPress specific here. Use PHP’s str_replace to replace tokens entered by users in the settings. In your plugin code, wherever you are echoing the setting value wrap it in str_replace with the value you want to replace %my_url% with. echo str_replace(“%my_url%”, $real_url_value, $setting_text);
You will have to use the rewrite API to get that to work. First you need to register the rewrite rule. add_action( ‘init’, ‘wpse23712_rewrites’ ); function wpse23712_rewrites() { add_rewrite_rule( ‘events/day/(\d{4}-\d{2}-\d{2})/’, ‘index.php?post_type=event&event_date=$matches[1]’, ‘top’ ); } Then add your event_date to the query vars so wordpress understands it. add_filter( ‘query_vars’, ‘wpse23712_vars’ ); function wpse23712_vars ( $vars ) … Read more
Have a look at this question for a fairly simple solution. Basically, create a plugin to contain your code, add a rewrite rule to intercept any requests that match your custom url, and parse or pass whatever data they contain to your plugin, which can then use those variables to produce whatever output you need. … Read more

WP doesn’t quite work that way. How WP does work is a long and involved discussion, but here’s the short version. (BTW, AJAX is a whole other thing entirely. There’s a whole system in WP just for doing AJAX requests easily, and most people are doing-it-wrong. If your question is AJAX specific, none of the … Read more
What flush_rewrite_rules(); does is call $wp_rewrite->flush_rules(); (Also called when updating permalinks). All plugins rewrite rules are regenerated then, so you dont need to worry about other plugins rules being “missing”. Also is not a good idea to call this function (flush_rewrite_rule) on hooks that run each time wordpress is loaded, and is enough to call … Read more
It appears that you have content (pages, posts or widgets) that contain old URL information. An example of a URL that is correct: http://www.hutchisonhaines.co.uk/wp-content/themes/FactoryWP/style.css An example of a URL that is incorrect: http://hutchisonhaines.co.uk.previewdns.com/wp-content/uploads/2012/02/flowers-944×290.jpg The quickest way to fix this problem would be to do a database dump and then run a search and replace program … Read more
First off, these aren’t CGI variables, they’re query string arguments. WordPress, by default, will remove any query arguments that it doesn’t recognize. So you need to register them with WordPress and then pull them back out of the query. First, add your new query variable: function wpa_48528_vars( $vars ) { $vars[] = ‘filter’; return $vars; … Read more
Edit. Here’s another solution to not mess with the edit slug button. The function get_sample_permalink_html in wp_admin/includes/post.php outputs the sample permalink and an edit button. It can be filtered like this: add_filter(‘get_sample_permalink_html’,’my_sample_permalink’,10,2); function my_sample_permalink ($page_link,$id){ $page = get_page($id); if($page->post_type == “page” && $page->post_parent) { $parent = get_page($page->post_parent); $page_link = preg_replace(“/(sample-permalink\”>).*?(<)/”,”$1″.home_url(“https://wordpress.stackexchange.com/”).$parent->post_name.”/$2″,$page_link); } return $page_link; } Can’t … Read more
WordPress has two kinds of rewrite rules- internal and external. Internal rules are parsed by WordPress and routed to index.php. External rewrites get written to .htaccess and are not directed to WordPress. Right now your rule is a mix between internal and external- you have it structured as an internal rule, but you have it … Read more
