Reading sub item / array

[coda-apps]

Hi there.

Thanks for setting up this git.

I have some sample code i am getting from paypal.

I would like to get the 'custom_id' variable (in: purchase_units) I tried custom_id = oJSON.data("purchase_units").item("custom_id") but it was empty. How would i access it? Is it different being within an array?

I also tried this, which works partially - i get an error on what seems to be the 2nd loop of the for loop. But the first loop does seem to access the tag i want. Maybe its throwing an error as this isnt a true array with multiple objects?

   For Each custom_id In oJSON.data("purchase_units")
        Set this = oJSON.data("purchase_units").item(custom_id)
        Response.Write _
        this.item("custom_id")  
    Next

Thanks

The attribute "purchase_units" contains an unnamed container, this is probably the place where you have problems. In case you expect only one purchase_unit, you can access the first item directly by index. Otherwise you would have to loop through the collection.

Dim objJSONData : Set objJSONData = objJSON.data
Dim objPurchaseUnits : Set objPurchaseUnits = objJSONData.item("purchase_units")
Dim objPurchaseUnit : Set objPurchaseUnit = objPurchaseUnits.item(0)
MsgBox objPurchaseUnit.item("custom_id")

Thank you
