Hi @Anonymous :
If you want to add a attachment to a SP list item using Patch function directly, I afraid that there is no way to achieve your needs in PowerApps currently.
If you would like this feature to be added in PowerApps, please submit an idea to PowerApps Ideas Forum:
https://powerusers.microsoft.com/t5/PowerApps-Ideas/idb-p/PowerAppsIdeas
As an alternative solution, you could consider take a try to only add the Attachments field within the Edit form. I have made a test on my side, please take a try with the following workaround:
1\Add an edit form(Form3)
2\Add a button
OnSelect:
Patch(
'List A',/*'List A' is my data source*/
First('List A'),/*Modify the first record in the data source*/
{Title: "1"},
Form3.Updates
)
On your side, you should type following formula:
Patch(
'YourSPList',
'Your specified record',
{
Column1:TextInput1.Text,
Column2:TextInput2.Text,
Column3:TextInput3.Text,
...,
ColumnN:TextInputN.Text
},
EditForm1.Updates
)
Note: The Editform1 represents the Edit form control within your app, which only display the Attachments field.
I think these links will help you a lot:
