A quick question about validating custom profile fields during the registration process...
I've got fields showing, and in theory capturing based on the code at:
Validation on register_post didn't seem to work though, so I followed through the Codex to registration_errors...
Now I am able to interact with errors (which weren't available during register_post), but trying to register throws the following error:
PHP Fatal error: Call to a member function get_error_code() on a non-object in ...\wp-login.php on line 316
Trying to trace that error shows that it happens often with plugins that interact with registration (apparently Sabre is high on the list), but I get nothing in terms of a recommended fix.
NOTE: I get the error whether I send things through empty (i.e. all errors on required fields) or completely filled in.
I've confirmed I have a WP_Error object through the body of my validation function, and a print_r indicates all should be fine from start to finish (with a few errors getting added if appropriate) but it seems like the WP_Error object is getting mangled by the time it returns to wp-login.php...
Has anybody seen anything on successfully adding and validating profile fields for WordPress 3.3.x and up?
NOTE: I'd upgrade to 3.4.x but I'd rather fight this battle, then worry about plugin compatibilities, etc.
ADDITIONAL: I'm also doing this for a stronger integration with the admin than a plugin like WP-Members offers (which works, but works differently... and undesirably so).
Any assistance would be greatly appreciated!
