Map Phone Numbers to Buddypress Profile

1.
sorry, abit confuse on what you are trying to achieve here (can you rephrase) however EMPro already has custom booking form with User Fields – https://wp-events-plugin.com/documentation/payment-gateways-overview/

2.
sorry, this isn’t possible at the moment.

For number one I want the phone number field to be displayed and able to be edited in the buddypress user profile.

1. at the moment, BP and EM user fields don’t integrate together (on the todo list), EM Pro can integrate with any plugin that stores fields individually within the wp_postmeta table (BP does not)

2. doubt this would happen anytime soon, if at all, you’d need to create a custom hook for this.
