When I click to add items to the shopping cart, the issue arises where clicking on one item's quantity updates all items to the same number. How to get avoid to the same number in all items.
Assuming a collection called colCart is the gallery Items, ie
Share
Report
All responses (
Answers (
ClearCollect(
colCart,
{ title: "In Stock", amt: 0},
{ title: "Remaining", amt: 0},
{ title: "Out of Stock", amt: 0}
)
ChevronUp
Patch(colCart, ThisItem, {amt: ThisItem.amt+1})
ChevronDown code
If(ThisItem.amt > 0,Patch(colCart, ThisItem, {amt: ThisItem.amt-1}))
Hi @dylandavis09, 😊
As I mentioned in your previous topic, a variable will unfortunately not work when working with a gallery / an array of data. The variable is global and will not be specific to one item - you will need to keep track of the quantity for each item individually. You could create a collection from your gallery data (Items property) and add a column to keep track of the selected quantity.
(1) OnVisible of that screen
//Should you already use a collection for the gallery - make sure to just add the AddColumns as below (don't create a new collection)
//Add a quantity column to keep track of the added numbers for each item
ClearCollect(
colShoppingCart,
AddColumns(
<Items property of gallery>,
"Quantity",
0
)
)
(2) Set your gallery Items property to the new collection
colShoppingCart
(3) OnSelect of the Up arrow
Patch(
colShoppingCart,
ThisItem,
// -1 for the down arrow
{Quantity: ThisItem.Quantity + 1}
)
(4) DisplayMode of the Down arrow (to avoid quantities below 0)
If(
ThisItem.Quantity = 0,
DisplayMode.Disabled,
DisplayMode.Edit
)
If this solves your question, would you be so kind as to accept it as a solution & give it a thumbs up.
Thanks!
I would suggest to create different variables for these categories.
Instead of using varNumber for all three:
varNumberInStock
varNumberRemainingLefts
varNumberOutOfStocks
If you have any questions or feedback, please let me know. Have a great day! 😊
