Shopping Cart app | count ++ selected galleryitem & collect shopped items

[Anonymous]

Hi guys,

I'm pretty new to powerapps and i'm trying to make a shopping card. I have a gallery selected with my products and i added a textinput and a add icon. Basically i want to be able to click the items i want and to count them. The screen underneath will explain what i am looking for.

In addition i am trying to collect all the items that are filled in. I am collecting values but its not working correctly.

Code that i have now for collecting shopped items: 

ForAll(Gallery1.AllItems,Collect(ShoppingCart, {itemType:Gallery1.Selected.itemCategoryCode, itemName:Gallery1.Selected.displayName,itemQuantity:TextInput1.Text}))

I tried this code for the "on select" of the add icon to see if i could only get one of the gallery item textboxes to be ++

Gallery1.Selected.TextInput1.Text="1"

Once i figure out how to get this to work i will finetune the code with if statements.

Kind regards,

Anthony

Hi @Anonymous ,

There is no need to repeat the gallery reference - you are already collecting AllItems and .Selected will only reference one record (the one selected)

ForAll(
   Gallery1.AllItems,
   Collect(
      ShoppingCart, 
      {
         itemType:itemCategoryCode, 
         itemName:displayName,
         itemQuantity:TextInput1.Text
      }
   )
)

Hello @WarrenBelz ,

Perfect this works. Can you help me with the first bit of code as well? So how i can ++ and eventually also -- every separate gallery item? I haven't done this yet. I have no clue how to only ++ the textbox corresponding to the item.

King regards, 

Anthony

Hi @Anonymous ,

You would need a checkbox in the gallery (you can only select one item at a time) and check that. Using the name chkCount  for the checkbox, your count would be 

CountRows,
   Filter(
      Gallery1.AllItems,
      chkCount.Value
   )
)
