通过PHP将多维数组发布到服务器[重复]

multi-dimensional array post from form

I would like to send some data from the client to the PHP server using jQuery $.post(). When it arrives at the server, I would like $_POST['myList'] to be equal to either of the following (what ever is easiest). What should I set the data object to within $.post()?

array (
  0=>array('id'=>123,'d1'=>'aaa','d2'=>'xxx'),
  1=>array('id'=>234,'d1'=>'bbb','d2'=>'yyy'),
  2=>array('id'=>345,'d1'=>'ccc','d2'=>'zzz')
)

array (
  123=>array('d1'=>'aaa','d2'=>'xxx'),
  234=>array('d1'=>'bbb','d2'=>'yyy'),
  345=>array('d1'=>'ccc','d2'=>'zzz')
)

EDIT: first one looked like a simple array of objects, but seems jQuery needs this to be a keyed object:

var send_this = {
  0: { id: 123, d1: 'aaa', d2: 'xxx' },
  1: { id: 234, d1: 'bbb', d2: 'yyy' },
  2: { id: 345, d1: 'ccc', d2: 'zzz' }
};

Second looks just has different looking keys for object containing objects:

var send_this = {
  '123': { d1: 'aaa', d2: 'xxx' },
  '234': { d1: 'bbb', d2: 'yyy' },
  '345': { d1: 'ccc', d2: 'zzz' }
};

Tested implementation in jQuery 1.7.1:

$.post( '/herp.php', send_this, function(d) {
    console.info( d );
});

The PHP program receives data exactly as you want it in $_POST.

You could send them as three arrays, one for each attribute.

myList_id[]=123&myList_d1[]=aaa&myList_d2[]=xxx&myList_id[]=234&...

In PHP, you will recieve them as $_POST['myList_id'], $_POST['myList_d1'] and $_POST['myList_d2'], which you could combine into your desired array.

Or if you include indices, you could go a step further:

myList[0][id]=123&myList[0][d1]=aaa&myList[0][d2]=xxx&myList[1][id]=234&...

which will give you the array directly: $_POST['myList']

You should use a JSON strong to send the data: Here is an example:

var pushData = {
        id: "blalal",
        id: "blalal",
        id: "blalal",
    };
JSON.stringify(pushData)

and then you can just post it or whatever

$.ajax({
    url : "http://blalallalalal="+JSON.stringify(pushData),
    type : "POST",
    dataType: "text",
    success: function (data) {

    },
    error: function() {
        // alert("fsdf");
    }
});

then from php side just use

$data = get_object_vars(json_decode($dataJSON));

DONE

If your using jQuerys $.post or $.get, you do not need to encode/decode, just pass a JS object as the data argument...

var data = {
  "myList" : {
    0 : {"id":1,...etc},
    1 : {"id":2,...etc},
    2 : {"id":3,...etc},
    etc...
  }
};


// post or get
$.post(
  url2post,
  data,
  callbackFunc
);

Option 1

var data = [
  { id: 123, d1: 'aaa', d2: 'xxx' },
  { id: 234, d1: 'bbb', d2: 'yyy' },
  { id: 345, d1: 'ccc', d2: 'zzz' }
];

Option 2

var data = {
  '123': { d1: 'aaa', d2: 'xxx' },
  '234': { d1: 'bbb', d2: 'yyy' },
  '345': { d1: 'ccc', d2: 'zzz' }
};

then

$.post(url, {mylist: data});
