Pending approval

Is there a way to make all fields a user can edit to be in a pending approval status after edited by the user?
In other words, whatever a user changes, to change after a moderator approves that change.
So a user can't change anything without approval.

No, there isn't account wide re-approval. There is only individual field approval for image fields. We'll be addressing this sometime in CB 3.x with support for approval on any field type. I suppose it's possible to implement this somewhat using CB Auto Actions, but you'd have to temporarily disable their account by making their entire account unapproved again.

Any example would be much appreciated

You would have to be ok with completely disabling their account. Is that what you're wanting? They won't be able to login and will be logged out after making changes to those fields.

Yes, project runs on a local server with only sample users, so not an issue.

Thank you

The below can be used to perform any action on a field value change.

Global
Triggers: onAfterUserUpdate
User: Automatic
Access: Everybody
Conditions
Field: Custom > Value
Custom Value: [var1_FIELD_NAME]
Operator: Not Equal To
Value: [var3_FIELD_NAME]

Replace FIELD_NAME with the name of the field you want to condition against. Next lets combine this with a Code action to disable their account in the below example.

Global
Triggers: onAfterUserUpdate
Type: Code
User: Automatic
Access: Everybody
Conditions
Field: Custom > Value
Custom Value: [var1_cb_address]
Operator: Not Equal To
Value: [var3_cb_address]
Action
Method: PHP
Code:
The above example should block their account and mark it pending moderator approval if the cb_address field is changed.
