|
|
*
|
|
* 1. Create a new extra field in main/admin/user_fields.php with the "TAG" field type make it available and visible. Called it "books" for example.
|
|
* 2. Go to profile main/auth/profile.php There you will see a special input (facebook style) that will show suggestions of tags.
|
|
* 3. All the tags are registered in the user_tag table and the relationship between user and tags is in the user_rel_tag table
|
|
* 4. Tags are independent this means that tags can't be shared between tags + book + hobbies.
|
|
* 5. Test and enjoy.
