How to Read JSON Post Object from PHP

Question

I have a problem with "JSON, JQuery, Ajax, JavaScript and PHP". I have code to save data. This code send data(JSON) via JQuery Ajax to proses.php. The code for save data shown below :



    $("#save").click(function(){
        var id_promotion_code = $("#id_promotion_code").val();
        var i=0;
        var y=0;

        var datarule = {
            rule: []
        };

        $('#tablerule tr').each(function() {
            if(y!=0)
            {
                var id_pricing_rule = $(this).find("td").eq(0).html();              
                var date_book_start = $(this).find("td").eq(3).html();              
                var date_book_end = $(this).find("td").eq(4).html();   
                var date_book_no_end = 0;
                if(date_book_end=="NO END")
                {
                    date_book_no_end = 1;
                    date_book_end = $(this).find("td").eq(3).html();
                }
                var date_reservation_start = $(this).find("td").eq(5).html();               
                var date_reservation_end = $(this).find("td").eq(6).html();             
                var date_reservation_no_end = 0;
                if(date_reservation_end=="NO END")
                {
                    date_reservation_no_end = 1;
                    date_reservation_end = $(this).find("td").eq(5).html();
                }
                datarule.rule.push({ 
                    "id_promotion_code" : id_promotion_code,
                    "id_pricing_rule" : id_pricing_rule,
                    "date_book_start" : date_book_start,
                    "date_book_end" : date_book_end, 
                    "date_book_no_end" : date_book_no_end, 
                    "date_reservation_start" : date_reservation_start, 
                    "date_reservation_end" : date_reservation_end, 
                    "date_reservation_no_end" : date_reservation_no_end
                });
                i++;
            }
            y++;
        });
        $.ajax({
            type:"POST",
            url:"proses.php",
            data:"aksi=tambahrule&datarule=" + datarule,
            success: function(data){
                alert("Sukses " + data);
            },
            error: function(){
                alert("Error" + data);
            }
        });
    });

And the code in proses.php shown below :



    if($aksi=='tambahrule'){
            $datarule = $_POST['datarule'];
            $jsone = json_decode($datarule, true);
            print_r($jsone);
    }

But i can't get the json data with proses.php code. Please help me how to read json object that send via jquery ajax with php? Actually i want to looping the json for get the data.

------------------------MY NEW EDIT-----------------------------

Thanks for your response... I already modify my code. And running but not well yet. This is the response when i check using Firebug :



    Array
(
    [rule] => Array
        (
            [0] => Array
                (
                    [id_promotion_code] => 
                    [id_pricing_rule] => BN2
                    [date_book_start] => 2012-03-01
                    [date_book_end] => 2012-03-01
                    [date_book_no_end] => 1
                    [date_reservation_start] => 2012-03-09
                    [date_reservation_end] => 2012-03-09
                    [date_reservation_no_end] => 1
                )

            [1] => Array
                (
                    [id_promotion_code] => 
                    [id_pricing_rule] => EB10%
                    [date_book_start] => 2012-03-15
                    [date_book_end] => 2012-03-15
                    [date_book_no_end] => 1
                    [date_reservation_start] => 2012-03-31
                    [date_reservation_end] => 2012-03-31
                    [date_reservation_no_end] => 1
                )
        )
)

And this is the PHP code for get the data :



        $datarule = $_POST;
        $rulenya="";
    foreach($datarule->rule as $doc) 
    {
        $rulenya=$rulenya.$doc->id_pricing_rule;
    }
    print_r($datarule);

But get the error. My question is? 1. The data is in Array, should i change to Object? And how? 2. How can i get that data in PHP?

I think you should send the data in another way:

data: { aksi: "tambahrule", datarule:  datarule},

as datarule is a complex object and can't be appended to a querystring. Serverside your code should be ok

Try using dataType: 'json', in your ajax call.

That's for receiving the response back, it has nothing to do with sending, which is the problem here.

The answer of Nicola Peluchetti is correct, datarule is NOT a querystring, you need to send it as he explained.

Furthermore, having your data as an array is fine. But you need to alter your server code to handle it as such:

$datarule = $_POST['datarule'];
$rulenya = '';
foreach ($datarule['rule'] as $doc) {
    $rulenya .= $doc['id_pricing_rule'];
}

or something along those lines...

You don't json_decode. You can try it;

PHP Code:

$datarule = $_POST['datarule'];
$datarule = implode(',', $datarule);
print_r($datarule);

$datarule is a array
