Hi Marco.
1) With WP Users it is possible to see some information of a member. At this moment members of my website can change their profile in s2member. Those changes are not made in wordpress. Is there any way (maybe a plugin like WP users) to show the profiles of the members created by s2member?
By WP Users you mean this? http://wordpress.org/extend/plugins/amr-users/
The s2Member custom profile fields are stored in WordPress, but with a different format, so not every user directory knows how to get to it. The AMR one can, though. http://wpusersplugin.com/3086/user-lists-and-filtering-with-s2member-fields/
2) I am a user of the pro forms. Are the pro forms compatible with buddypress?
The pro-forms don’t integrate with BuddyPress profile fields, if that’s what you mean. If you mean if creating a user with a pro-form will make an account in a site that has BuddyPress, then yes. You can use a free registration pro-form in your BuddyPress site and test it. [hilite path]Dashboard -› s2Member® -› PayPal® Pro Forms -› Free Registration Forms[/hilite]
3) Is het possible to create a link to a s2member profile? For example. I use an event manager and I would like to show some member information to every visitor of an certain event.
The profile itself is WordPress’, not s2Member’s. User profiles are not public in WordPress, but there are plugins that help with that, like BuddyPress.
Or by s2Member profile, do you mean the s2Member custom profile fields? [hilite path]Dashboard -› s2Member® -› General Options -› Registration/Profile Fields[/hilite]
These can be gotten from the database to display in a page with some custom coding. http://www.s2member.com/codex/stable/s2member/api_functions/package-functions/#src_doc_get_user_field%28%29
I hope that helps. :)
