: How to allow user to enter text or upload file, but not both We used to have a two-step process for answering questions. On the first page the user indicated how he would answer: either

@Welton855

You could create 2 radiobuttons. So that the user can make the choice whether he wants to add text or upload a file.
Or you could even do it without the radiobuttons and let the user click on the element he wishes to use.

When the user changes the radiobutton you can use javascript to disable the other field. Indicating he cannot use both fields.

If you do this it is very important to also check it at the backend code (php / asp / whatever) since it would be trivial to circumvent this (by disabling JS or by changing the DOM).
