How to make variables in URL look like the permalink structure?

1. The following two functions should point you in the right direction:

   function wpse49393_query_vars($query_vars)
   {
       $query_vars[] = 'myvar';
       return $query_vars;
   }
   add_filter('query_vars', 'wpse49393_query_vars');
   
   function wpse49393_rewrite_rules_array($rewrite_rules)
   {
       $rewrite_rules['path/to/page/([^/]+)/?$'] = 'index.php?pagename=path/to/page&myvar=$matches[1]';
       return $rewrite_rules;
   }
   add_filter('rewrite_rules_array', 'wpse49393_rewrite_rules_array');
   

   I would give credit where it is due, but I cannot remember where I originally found this code. I just pulled this out of a project that I am currently working on. To use it, change myvar to the name of your variable in the first function as well as here: &myvar=$matches[1]. Change path/to/page/ to the actual path of your page at two locations in the second function.

2. You can do you’re own custom permalink structures, have you looked here – http://codex.wordpress.org/Using_Permalinks?

3. Thanks to this post for the heads up: http://zagar.biz/2011/wordpress-creating-custom-permalinks/

   My final code ended up being like this:

   In the theme’s functions.php file

   add_filter('rewrite_rules_array','mycode_add_rewrite_rules');
   
   // Add all rewrite rules here
   // ** Remember to Flush Rewrite rules when adding new rules.
   // this is done by visiting the Settings > Permalinks in WP admin.
   
   function mycode_add_rewrite_rules($rules){
       $newrules = array();
       $newrules['tal-dia-como-hoy/([^/]+)/([^/]+)/?'] = 'index.php?pagename=tal-dia-como-hoy&dia=$matches[1]&mes=$matches[2]';
       return $newrules + $rules;
   }
   
   add_filter('query_vars','mycode_add_rewrite_query_vars');
   
   // Add all slugs so that WP recognizes it
   function mycode_add_rewrite_query_vars($vars){
       array_push($vars, 'dia');
       array_push($vars, 'mes');
       return $vars;
   }
   

   Then, in the page I created. This is just a regular wordpress page, not a template or anything like that

   global $wp;
   
   // connect to your external DB, etc...
   
   if($wp->query_vars["dia"]){
   
   echo "Permalinks are working";
       // load up your external data here and display single resource
           // if the beard slug doesn't exist, redirect to 404
   } else {
       // load up whatever you want to display for the index version.
   echo "Nothing shows up but it's working anyway";
   }
   

   I have to edit the page to make it look good with my brand new permalinks.

   This is the page I’ll using with this code: http://planeta-beisbol.com/tal-dia-como-hoy/19/04/

   The “19/04” part means: 19th of April

   I hope this code is useful for everybody
