Hi I am trying to add an upload field and a radio button field for our members in EE2 but when adding a custom member field you only have a choice of text input, text area, or drop down http://expressionengine.com/user_guide/cp/members/custom_member_fields_edit.html#field-type
Is there anyway to have access to all of the field types in EE for custom members fields?
Not natively, no. But there are two add-ons you should look at that will both give you the flexibility you need - both are from reputable developers.
