the 'Required Location' mod updates the existing profile field location and makes ALL location fields "required" including country/state/city. If the database has no states or cities listed for a particular country then only the country is required because it only loads for selection what is found in the database.
Installation is the same for any other addon.
1. Download the field_loc_req-1.02.zip package and upload it on your server into the tmp/packages folder. DO NOT unzip it.
2. In your admin panel go to the "Package Manager" page. You should see the addon listed there with an "install" link next to it.
3. Click on install and follow the instructions on screen if any.
If you already have members and are upgrading the profile field location and don't want to lose the information they have already entered into that field then you should run the following SQL statement against your database:
UPDATE `dsb_profile_fields2` SET `field_type`='field_loc_req' WHERE `field_type`='field_location'
Then in your admin panel go to Profile Fields from the menu and click on the top link to regenerate the profile fields cache.
Make sure you backup at least the
dsb_profile_fields table if not the whole database before making any change.
You can run the SQL query with a database management tool like phpMyAdmin which should be available in your server control panel.
