reading an array of arrays of objects in ajax

Question

I have three data coming back from an ajax call. I pack them into an array like this:

return json_encode([$salesOrder, $soAddressDetails, $lineItems]);

I then go to the view and look at the return. I see (as an example) this:

[
    [{
        "id": 8591,
        "reference": "MYCLIENT",
        "name": "MYCLIENT COMPANY \u00a3",
        "allocated_status": "",
        "created_at": "2016-12-02 09:31:00",
        "order_date": "2016-12-02",
        "cust_order_number": "",
        "del_name": "",
        "consignment": "",
        "despatch_date": "0000-00-00",
        "notes_2": ""
    }],
    [],
    [{
            "id": 11691,
            "qty_ordered": 1,
            "qty_delivered": 0,
            "sales_order_id": 8591,
            "due_date": "2016-12-30",
            "stock_code": "ABC-ABDCDE-01",
            "record_deleted": 0,
            "updated_at": null,
            "unit_price": 0,
            "sales_order_item_id": null,
            "comment": null,
            "created_at": null,
            "firmware_version": null,
            "units_assigned": null
        },

        {
            "id": 11692,
            "qty_ordered": 1,
            "qty_delivered": 0,
            "sales_order_id": 8591,
            "due_date": "0000-00-00",
            "stock_code": "MISCELLANEOUS",
            "record_deleted": 0,
            "updated_at": null,
            "unit_price": 232,
            "sales_order_item_id": null,
            "comment": null,
            "created_at": null,
            "firmware_version": null,
            "units_assigned": null
        }
    ]
]

In theory all I should need to access this, as array result is:

result[0] // sales order details
result[2] // line items = array of objects

so

result[0].reference == 'MYCLIENT'

and

result[2][0].stockcode == 'ABC-ABDCDE-01

but it won't let me do that. if I console.log(result[0]) the result is [, if I console.log(result[0][0].id) the result is undefined.

what am I doing wrong?

Tested in the console and result[0][0].id worked. How are you trying to access it ? Where result comes from ? — DontVoteMeDown

Try doing JSON.parse(result), seems like your result is still a string — surajck

How are you retrieving the json from php? Ajax (jquery, angular, vanilla, etc..) or a regular request? — Gabriel Heming

JSON PARSE! I forgot JSON.parse. It has been a long day. Suraj if you make that an answer I'll accept it. And thanks all. — gedq

From the last line of your question, seems like your result is still a string.

Try doing JSON.parse(result)

Either you need to say that your response will be Json in your ajax like this

 dataType: 'json'

Or after getting response you have to convert it into json object

response = JSON.parse(response);

I think you just miss the level. The reference it's also in a second level. So you need to access it like:

console.info(result[0][0].reference)
