Actually that isn’t technically true, Slavick. I am currently trying to code a WP/SMF bridge myself since I can’t seem to find one. I’m having limited success so far as I am still learning PHP. Be that as it may, I am not new to programming, so I hopefully will get the job done in the end; it’s a slow process climbing that learning curve again after you’ve been away from coding for some years… ??
Using either SSI.php or smf_api.php (or a combination of both, as required), you can compare the username entered for WP login against the SMF member’s table. Theoretically then, if that particular WP user exists in both tables, simply extract it via sql and use it to do whatever it is you’re attempting. This would also apply to inserting a newly registered user into both the SMF and WP tables or updating a user’s profile information.
Cheers!
