Upload Validation

ahmada674 over 8 years ago

Dears ,

I have a concern about the validation on the upload documents if i need to specify the type if document that i want the user to upload for example i need the user to upload only .doc and the user change the excel extension to be from .excel to .doc the Appian upload will accept that as a .doc while it's not.

So is there a solution to validate this issue depend on the uploaded file it self with no consideration of the extension name cuz the user can by pass this by change extension.

Thanks and hopefully i can find the answer.

you can only decide type of the file based on extension. And one more thing if you change the extension then file type will change. For example if i change .pdf to .docx then file becomes .docx file. I don't think we can detect whether file type is changed or not.

Suppose lets say in Windows when you go and change the extension in Save As, it completely changes the properties of the file from .doc to .xls . Appian relies on those properties to provide the extension or filename related information.

As far as I know the solution you are looking might not be possible with OOTB features and you might have to write a plugin to achieve this.
