Getting Custom User Fields in Plugin

[1qaz0okm13]

I am currently trying to make a plugin which checks a custom userfield against an external database during registration (register_addmember_process hook) and if the database does not contain the field the registration is denied. I have done 90% of it just I am unable to find out how to get custom userfields during registration. How can this be done?

You should be able to check the value of $vbulletin->GPC['userfield']['fieldX'] (where X is the actual field ID of the custom field you want to check). If it's a text field it will be text of course, otherwise the value may just be a number representing the selection. As always you should be careful when using the value in a query (use mysql_real_escape_string() or something like that).
