Change each items quantity based on button click

Posted on by Johnane 41

I have gallery that collects all the items the user adds from the previous screen using a "Add to Cart" button. 

In the gallery there's a quantity text input (varQty) and two buttons (+ and -) "See below Image"

For the buttons, I use the following code:

Set(varQty, varQty + 1)

Set(varQty, varQty - 1)

 

When I have more than 1 item in the gallery and click on the buttons, it updates the quantity for all the items.

How to I let the buttons only update the respective item I'm trying to update?

    Hi,

    In the gallery where you collect the info, add a new column 'quantity' and everytime the user click on the button update the current item quantity.

    I think this is the best approach

     

    Any question let me know.

    I hope it helps 🙂

    Is the button outside the gallery?

     

    If yes, I recommend you put your button inside the gallery and, on select property of the button you write:

     

    Patch(

    YourDataSource,

    ThisItem,

    {

    Quantity: varQty

    }

    )

     

    I think it should work. Please, pay attention to the name of the fields and datasource names.
