Add role to user after joining organic group with rules

Question

I'm trying to add a user role to a user who has become a member of a group. The workflow is like this:

• User requests to join group.
• Request is approved by group administrator.
• User is a member of the group.
• User gets an additional role.

I've tried to make a rule which would be able to do this, but although all the settings seem correct after joining the group the user doesn't get the additional role. See below a screenshot of my rule settings:

Answer 1

Now your Rule runs after user requests membership. But you should run it after OG membership was approved.
I prepared Rule which adds role “member” after membership was approved or if it was added by admin (auto-approved). Here is export (4 is id of my drupal role “member”):

{ "rules_after_add_user_to_group" : {
    "LABEL" : "After add user to group",
    "PLUGIN" : "reaction rule",
    "TAGS" : [ "test" ],
    "REQUIRES" : [ "rules", "og" ],
    "ON" : [ "og_user_insert", "og_user_approved" ],
    "IF" : [ { "data_is" : { "data" : [ "og-membership:state" ], "value" : "1" } } ],
    "DO" : [
      { "user_add_role" : { "account" : [ "account" ], "roles" : { "value" : { "4" : "4" } } } }
    ]
  }
}

Tip: you can enable Rules debug (page admin/config/workflow/rules/settings) to see when your rules are executed.

Answer 2

I have the same issue (that why I started a bounty).

I solved it this way.

I added a function to a custom module. You can simple create your own module by making a new folder in /sites/all/modules with two files:

yourname_module.info ->>

name = "Custom Functions"
description = "Allows execution of custom code for the website"
core = 7.x
package = "yourname_customs"
version = 7.x-1.x

yourname.module

<?php 
function yourname_add_role_to_user($uid, $role_name) {

    $user = user_load($uid);

    if ($user === false || !isset($user->uid) || !is_array($user->roles)) {
        //Display an ugly error when user is not set correctly
        exit('$user is not set correctly <pre>' . print_r($user, true) . "</pre>");
    }

    //Get the user roles
    $roles = user_roles(TRUE);
    $rid = array_search($role_name, $roles);

    if ($rid != FALSE) {
        $new_role[$rid] = $role_name;

        // Add new role to existing roles.
        $all_roles = $user->roles + $new_role;

        //Delete all user roles from DB
        db_delete('users_roles')
                ->condition('uid', $user->uid)
                ->execute();

        //Insert all user roles in DB
        $query = db_insert('users_roles')->fields(array('uid', 'rid'));
        foreach (array_keys($all_roles) as $rid) {
            if (!in_array($rid, array(DRUPAL_ANONYMOUS_RID, DRUPAL_AUTHENTICATED_RID))) {
                $query->values(array(
                    'uid' => $user->uid,
                    'rid' => $rid,
                ));
            }
        }
        $query->execute();
    } else {

        //Display an ugly error wen role not found
        exit("Could not find role " . htmlspecialchars($role_name) . "<br/>
              Vald roles: <pre>" . print_r($roles, true) . "</pre>");
    }
}

Then goto your modules and enable "Custom Functions".

Make sure you have module custom php code enabled.

Then instead of action add user to role in rules, add: run custom php code and enter:

yourname_add_role_to_user($account->uid, "Members");
header("Location: /admin/people");
exit;

This adds the user to the role, and stops the script. If you don't stop the script, the role is not saved. And I needed to add a module because user_save does not work when executed in custom php code.

So, I know it is very ugly, but it works for me.

Which version of OG do you run ?

This is a know bug that have been fixed with Organic Group 2.4+ (see bug page).

If you are already running a 2.3 or lower version of OG the updgrate should be straightforward. If you are running OG 1.x, you can find more details on the update process from OG 1.5 to 2.4+
