How can I post a JSON multi-dimensional data via Jquery.post?

How can I post a JSON multi-dimensional data via $.post? For instance, I have this multi-dimensional array in JSON format开发者_运维技巧:

{
    "file":
    {
       "name" : "1024x768.jpg",
       "type" : "image\/jpeg",
       "tmp_name" : "C:\\wamp\\tmp\\php8F59.tmp",
       "error":0,"size":469159
    }
}

I will use Jquery.post() to post the JSON data.

$.post("process.php",'{"name":"1024x768.jpg","type":"image\/jpeg","tmp_name":"C:\\wamp\\tmp\\php8F59.tmp","error":0,"size":469159}}',function(xml){

});

So I can get this array in process.php using print_r($_POST):

Array
(
    [file] => Array
        (
            [name] => 1024x768.jpg
            [type] => image/jpeg
            [tmp_name] => C:\wamp\tmp\phpA1.tmp
            [error] => 0
            [size] => 469159
        )
)

Is this possible?

Try this:

$.post("process.php",{"file":{"name":"1024x768.jpg","type":"image\/jpeg","tmp_name":"C:\\wamp\\tmp\\php8F59.tmp","error":0,"size":469159}},function(xml){

});

that should give you the desired array on the php side

Edit: this works since jQuery 1.4 and above

$jsonArray ='{"file":{"name":"1024x768.jpg","type":"image\/jpeg","tmp_name":"C:\\wamp\\tmp\\php8F59.tmp","error":0,"size":469159}}';
$arr = JSON.stringify($jsonArray);

$.post("/url",{data:$arr},function(){

});

in the php file do

$json = json_decode($_POST['data']);
print_r($json);

Edit

may be this will help, i have not tested it though...

var file=[];
file["name"]="1024x768.jpg";
file["type"]="image/jpeg";
file["tmp_name"]="C:\wamp\tmp\phpA1.tmp";
file["error"]="0";
file["size"]="469159";


var myObject = new Object();
var enumm=["name","type","tmp_name","error","size"];

function getEnum(index){
    return enumm[index];
}


$.each(file,function(i,j){
myObject[getEnum(i)]=file[getEnum(i)];
});


$.post("/url",{data:$.param(myObject)},function(xml){

});

on the php side do

$json = parse_str($_POST['data'], $data);
print_r($json);
