Question

How can I post a JSON multi-dimensional data via $.post? For instance, I have this multi-dimensional array in JSON format:

{
    "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?

Answer 1

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
