Is there a way to access the label, field value, and error of Member fields in a Safecracker form? I'm looking for something like http://ellislab.com/expressionengine/user-guide/modules/safecracker/#field-my-field-name, but for member fields. Thoughts?
Safecracker only supports channel fields. You'll want to use something like FreeMember, Solspace User, or Zoo Visitor to update member data. (there are a few other addons that also do this, try searching devot-ee for them)
