Ajax / PHP：传递变量

Question

When I'm passing the two variables to my php I get Notice: Undefined index : name & Notice: Undefined index : parsed.

When I'm adding an echo for each variable, I get nothing.

Nothing is added in my database.

name = "myName";
parsed = someCode.toJSON();

parsed = JSON.stringify(parsed, null, '\t');
parsed = parsed.replace(/[
\t]+([\d\.e\-\[\]]+)/g, '$1');

$.ajax({
    url: 'js/function/scriptSave.php',
    type: 'POST',
    dataType: 'JSON',
    data: {name : name, parsed : parsed},
    success: function(result) {
        alert("Success");
    },
    error: function(err){ 
        alert('Error'+err);
    }
});

The Ajax always returns me the error case : Error [object Object]

When I'm replacing my variables with text, everything works:

data: {name : 'name', parsed : 'parsed'}

And when I remove the json variable only it works. I really don't understand what happens here..

[EDIT]

The variable containing the name is ok. But when I only put the variable containing the json, it doesn't work. But what is the problem with this variable ?

So far, I have tried:

    var obj = {}; obj.name = 'myName'; obj.parsed = someCode.toJSON();
    {data : JSON.stringify(obj)}
///////
    {'name' : name, 'parsed' : parsed}
///////
    {parsed : JSON.stringify(parsed)}

Here's my php:

<?php
if (!@mysql_connect('localhost', 'user', 'pwd')) {
    die("Error");
} else {
    mysql_select_db('database');
}

    $parsed = $_POST["parsed"];
    $name = $_POST["name"];

    mysql_query("INSERT INTO object(name, parsed) VALUES ('".$name."', '".$parsed."')");
?>

[EDIT 2]

When I'm changing dataType from JSON to TEXT the ajax is in success case, but nothing is inserted in DB...

When I'm looking in my devTools in chrome everything semm to be ok :

General

Request Method :POST
Status Code: 200 OK

Response Headers

Content-Type: text/html

Request Headers

Content-Type: application/x-www-form-urlencoded; charset=UTF-8

Form Data

name : myName
parsed : {"another" : "value"}

[EDIT 3]

The problem seems to come from the json size... When I'm excluding some fields, everything seems to work. The problem is that in my databse, my field which will contain my JSON, is a LongText... The JSON size doesn't have to be the problem..

obj should be send as string, when calling the Ajax POST method.

So, combine the data into one Object and stringify it with JSON.stringify() method.

var obj = {};
obj.name = "your name";
obj.parsed = { "another" : "value" };

$.ajax({
    url: 'js/function/scriptSave.php',
    type: 'POST',
    dataType: 'JSON',
    data: JSON.stringify(obj),
    success: function(result) {
        alert("Success");
    },
    error: function(err){ 
        alert('Error'+err);
    }
});
