jQuery Ajax validation and DataAnnotations attribues -

-

i created form posts , gets results through jquery ajax. need put validation stuff on it. wonder how it. should use jquery validation plugin? if use , if i'm guessing right - there no need decorate model dataannotations attributes, no longer gonna make sense, right?

so i'm saying: use normal html form html.beginform(), not ajax form, override form's submit() function

$("form[action$='updatecalendarform']").submit(function ()  {     $.ajax({             url:  $(this).attr("action"),             contenttype: 'application/json; charset=utf-8',             type: "post",             data: json.stringify(calendardata),             datatype: "json",              success: updatecalendarcallback            });     return false; // wouldn't rerender page });  function updatecalendarcallback(result){  // , here on page }

what's best way add validation here without ajax helper methods (but using jquery) , dataannotations attributes on model properties.

brad wilson had great video on mvcconf validation. here's need know start implementing custom validation on mvc3

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

-
what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875
