javascript - Send form inputs with AJAX to PHP -

-

i want send form inputs page php function, using ajax, , save data in multidimensional array. there should no page reload, , response can simple true or false. in chrome browser, can see both inputs in "request payload" element, in json, how can retrieve data in php , transform data array?

html:

<div id="formeditbilling"><form> <input name="register[personal][firstname]" type="text" id="firstname" value="" class="text required " placeholder="firstname"> <input name="register[personal][lastname]" type="text" id="lastname" value="" class="text required " placeholder="lastname"> <input type="buttom" id="editbilling" value="speichern"/></form></div>

javascript:

<script type="text/javascript">  $('#editbilling').click(function() {     editbilling(); });   function editbilling(){      var url = '/checkout/saveaddress';  // server function      var data = $('#formeditbilling form').serializearray();     data = json.stringify(data);      $.ajax({         'type': 'post',         'async': false,         'data': data,         'url': url,         'contenttype': "application/json",         'datatype': "text",         'success': function (result, data) {      $('.output').html(data);    // output div  } }); } </script>

here's problem. how can array like:

['register'] => array      (          ['personal'] => array                  (                       ['firstname'] => "michael"                       ['lastname']  => "cooper"      )

php: here's attempt, it's not working, $_post seems empty.

public function saveaddressaction(){      $data = json_decode(stripslashes($_post['register']));      return true; }

your function's brackets aren't joining properly, try using this

function editbilling(){      var url = '/checkout/saveaddress';  // server function      var data = $('#formeditbilling form').serializearray();     data = json.stringify(data);      $.ajax({         'type': 'post',         'async': false,         'data': data,         'url': url,         'contenttype': "application/json",         'datatype': "text",         'success': function (result, data) {             $('.output').html(data);    // output div         }     }); }

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
