drupal 6: here code: http://pastebin.com/ggvffags

//getcity.js: $(document).ready(function() {     $("#edit-field-house-geo-area-value").bind('change', function(){          selected_loc=$("#edit-field-house-geo-area-value option:selected").val();         var myurl="http://whatever.com/getajax/citys/"+selected_loc+"/";         $.ajax({              type: "get",              url: myurl,              datatype: "json",              success: function(data){             console.log(data);              }             });      }); });

drupal module:

function sf_menu() {   cache_clear_all();   $items = array ();   $items ['getajax/citys/%'] = array ('title' => 'this custom page', 'page callback' => 'sf_get_cities_ajax', 'access arguments' => array ('access content' ), 'access callback' => 'user_access', // true give access 'page arguments' => array (2 ), 'type' => menu_callback );   return $items; }    function sf_get_cities_ajax($cityid) {   $termsarray = array ();   $terms = array ();   $cityid_safe = (int)$cityid;   $cityid_safe = check_plain($cityid_safe);   if (is_number($cityid_safe)) {     $terms = taxonomy_get_children($cityid_safe, 143, 'tid');     if (count($terms)) {       foreach ($termsarray $k => $v) {         $termsarray [check_plain($k)] = t($v [tid]);       }      $f= array('status' => 1, 'data' => $termsarray,'moo'=>'sadasdsd');     print drupal_json($f);      exit();     }    } }

its not return me somthing print 'moo' data

its function working fine array @ final dont pass

that looks should work except 1 thing... php doesn't have function 'is_number()' unless wrote own need change if statement use php built in 'is_numeric':

if (is_numeric($cityid_safe)) {

its not js issue @ all.

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
