Custom Capability control over Custom Fields

Currently, you can assign Custom Registration/Profile Fields availability to S2Member roles through the “Applicable Membership Levels” attribute of the custom field. Would it be possible to add the ability to S2Member to control these fields application based on Custom Capabilities?

We are trying to limit the number of member levels we use so that the number of roles does not get out of hand and instead control minor differences using Custom Capabilities. (As I think is suggested in Jason’s video tutorials.) But, the one area I’ve been unable to do this in is with controlling which profile fields a user sees.

Thanks

Hello Susan,

I’ll ask to Jason about this, and add it as a feature request.

Here’s what he answered:

This is NOT a finished piece of work, but it demonstrates how you might accomplish this with s2Member®.

Please create this directory and file:
/wp-content/mu-plugins/s2-hacks.php
(NOTE: these are MUST USE plugins, see: http://codex.wordpress.org/Must_Use_Plugins)
(See also: http://www.s2member.com/kb/hacking-s2member/)

<?php
add_filter('ws_plugin__s2member_custom_fields_configured_at_level', 's2_limit_custom_fields_further', 10, 2);
function s2_limit_custom_fields_further($fields, $vars)
    {
        if($vars['_editable_context'] !== 'profile' || current_user_can('edit_users'))
            return $fields; // Do NOT filter them any further in this case.

        // Else let's look at each field ID and Custom Capabilities.

        foreach($fields as $_key => $field_id)
            {
                switch($field_id)
                    {
                        case 'my_unique_field_id':
                            if(!current_user_can('access_s2member_ccap_music'))
                                unset($fields[$_key]);
                            break;

                        case 'another_unique_field_id':
                            if(!current_user_can('access_s2member_ccap_videos'))
                                unset($fields[$_key]);
                            break;

                        default:
                            break; // Allow the field to be edited.
                    }
            }
        return $fields;
    }

Thanks. That code make sense to me and I’ll try it out soon.
