It is now possible to add custom field values to Email templates since JoomBri Freelance v1.2.4
Here is the trick.
[CUSTOM_X_PUBLISHER] Custom Field ID of project publisher [CUSTOM_X_BIDDER] Custom Field ID of bidder [CUSTOM_X_PROJECT] Custom Field ID of project
In the above, X is the id of the custom field.
An example of this feature is illustrated below. After a Freelancer accept the offer from a Buyer, it might be necessary to share the contact info between the two users. To do so, go to Email Templates.
Bid Accepted (to publisher)
[CUSTOM_5_BIDDER] [CUSTOM_6_BIDDER] [CUSTOM_7_BIDDER] [CUSTOM_8_BIDDER]
Bid Accepted (to bidder)
Contact Details of Buyer: [CUSTOM_5_PUBLISHER] [CUSTOM_6_PUBLISHER] [CUSTOM_7_PUBLISHER] [CUSTOM_8_PUBLISHER]
In the above, 5,6,7,8 are custom field IDs.
