  • Nested Arrays retrieved withh json\retrieve

    I need help to kow haw many objects are there in an array that is nested inside other array.

    Let me explain in detail:

    I got a json that (detailed below) in a working field named $prJsonOrder

    What is relevant is that it has an array object: line_item and that array has nested other arrays: meta:data & taxes (see Json below)

    For normal objects I retrieve the data with this instruction
    $prName= json\retrieve($prJsonOrder, 'id');
    $prParentId = json\retrieve($prJsonOrder, 'parent_id');

    When dealing with the object line_item which is an array I need to know how many are there. So I used

    $prJsonLineItems = json\retrieve($prJsonOrder, 'line_items');
    $prJsonLineItemsCount = array\length($prJsonLineItems);

    Then I need to retrieve the individual data. For that I built a field ($prClave) with the exact address to retrieve. This is the code

    $prCont = 0;
    while($prCont < $prJsonLineItemsCount,
    $prClave = string\concatenate('line_items.', $prCont, '.id');
    $prName = json\retrieve($prJsonOrder, $prClave);
    $prClave = string\concatenate('line_items.', $prCont, '.name');
    $prNombreProducto = json\retrieve($prJsonOrder, $prClave);
    $prClave = string\concatenate('line_items.', $prCont, '.taxes');
    $prJsonOLTaxes = json\retrieve($prJsonOrder, $prClave);
    $prClave = string\concatenate('line_items.', $prCont, '.meta_data');
    $prJsonOLMetaData = json\retrieve($prJsonOrder, $prClave);
    $prCont = $prCont + 1);

    And this worked fine so far.

    The problem I have arises when trying to retrieve the next level of nested information. First of all I need to know how large is the array (how many objects) Taxes. As I know $prJsonOLTaxes is an array, so I used this:

    $prJsonOLTaxesCount = array\length($prJsonOLTaxes);

    But it fails. It is the same schema I used before. I had the array $prJsonLineItems and asked for that. Now, when using with $prJsonOLTaxes, it doesn't work.

    I reviewed my code and seems OK to me. Does anyone see anything wrong in it? May it be a bug?

    The data of the json is:
