How do I attach multiple files to a SharePoint list item using PowerApps and Power Automate

Posted on by Tetris

I am using a PowerApps app to create a new item in a SharePoint list with attachments, using a Power Automate flow. I can do that successfully by assigning the following to the "Create new item" button:

'FlowName.Run(Label1.Text,{contentBytes:First(DataCardValue6.Attachments).Value, name: First(DataCardValue6.Attachments).Name})

Where DatacardValue6 is the attachment control storing my attachments. Obviously, with "First" in the formula, the flow only uploads the first attachment in the box. What should I change in my formula for all the attachments in the box to be uploaded to the list?

I would suggest that you redo your PowerAutomate flow to allow for an array of files to be passed to it rather than just one. This would allow your formula to become:

'FlowName.Run(Label1.Text, DataCardValue6.Attachments)

It would be highly efficient as your flow would only be called once and all the data it needs is passed to it.

Otherwise, you can change your formula to include a ForAll function used in a backward way (this is the ONLY time you should use a ForAll backward like this!)

Ex.

ForAll(DataCardValue6.Attachments, 'FlowName.Run(Label1.Text,{contentBytes:Value, name: Name}) )

I hope this is helpful for you.

Hi, I tried using the ForAll function but it created multiple sharepoint list items based on the number of attachments submitted. Is there any other way to update all attachments to one sharepoint list item using powerappv2?

Hello Tetris

Hope you are using the Forall like below in PowerApps

ForAll(DataCardValue6.Attachments,
'FlowName.Run(Label1.Text,{contentBytes:Value, name: Name})
)

And in Powerautomate - the input type is File Type and using Add attachments to the list item ID that was created. This will not create new items.

If you don’t need Power Automate, Let SharePoint handle attachments natively by Just submit the form: SubmitForm(EditForm1)

Power Apps uploads all attachments automatically without any flow.
