Does anyone know a way (either programmatically or plugin) to assign tags to users.

I want to build a list of user interests as tags so I can match related content to their interests?

Cheers,

Chris.

I think this is what you are looking for: http://codex.wordpress.org/Function_Reference/update_user_meta

Here is a example of how this can be achieved: http://inchoo.net/wordpress/programatically-add-metadata-to-user-accounts-in-wordpress/

Thanks for the response. I'm not sure this is quite what I'm looking for. This is because the examples you've given show a one to one relationship between the meta field and value. I want to able to assign any number of tags to a user. For example if they liked sports the tags associated with their 'interest' fields would be 'football', 'hockey' 'basketball' etc. All these fields would be pre-existing post tags that I could assign to the user. Does this make sense? – chris Aug 8 '11 at 11:46
I'm not sure you're right, user7726, that user meta fields have to be 1-to-1. The codex page says "use the $prev_value parameter to differentiate between meta fields with the same key and user ID." This seems to imply that users can have multiple entries for "my_tag." On the other hand, I think you will have to use add_metadata($meta_type, $object_id, $meta_key, $meta_value, $unique = false) rather than update_user_meta. By default add_metadata doesn't check whether $user_id already has $meta_key. – Chris Carson Aug 8 '11 at 13:07
@Chris Carson, isn't it better to use update_user_meta if he wants to update this later? – Steven Aug 8 '11 at 14:59
@user7726 - Are you registering users? Or is the user signing up themselves and they select their interests? Either way, you only need to loop through the selected fields and update / add the fields. – Steven Aug 8 '11 at 15:01

@Steven I don't think it's possible to do "multiple metas with the same key and user_id" with update_user_meta. I think you have to use the lower-level metadata functions add_metadata and update_metadata. I may be wrong. – Chris Carson Aug 8 '11 at 15:25
