Please follow the steps in
our documentation page
on how to set up JomSocial Integration. You may also want to read the steps in our
Quick Start Guide
in the "Import Data into Profiles" section.
i want the user to go through the normal JomSocial registration by type username and pass and email , then fill the profile field , then i want to make user connect this account to facebook
Since you want to go through the regular JomSocial registration flow, then you'll want to set the JFBConnect > Configuration > General > Registration Flow to JomSocial. In this case, if the user pushes the login with FB button, they will redirected to Jomsocial and registered and will not have to subsequently connect the account in a separate step.
