Need this code to demote user role if points fall below minimum


Cybercli

Recommended Posts

The following code works as is to promote a user role when a points balance minimum is met, but I also need the role to change back to prior role if the points balance falls below the minimum. For example if points balance drops to 900 then the new role will be set to 'contributor'.

 /**
     * Promote Based on Balance
     * Changes a users role based on their myCRED balance.
     * @version 1.0.4
     */
    add_filter( 'mycred_add_finished', 'check_for_role_change', 99, 3 );
    function check_for_role_change( $reply, $request, $mycred ) {
        // Make sure that if any other filter has declined this we also decline
        if ( $reply === false ) return $reply;
    
        // Exclude admins
        if ( user_can( $request['user_id'], 'manage_options' ) ) return $reply;
    
        extract( $request );
    
        // Minimum balance requirement for each role
        $thresholds = array(
            'contributor'   => 100,
            'author'        => 1000,
            'editor'        => 10000,
            'administrator' => 100000
        );
    
            // Get users current balance
        $current_balance = $mycred->get_users_balance( $user_id, $type );
        $current_balance = $current_balance + $amount;
    
        // Check if the users current balance awards a new role
        $new_role = false;
        foreach ( $thresholds as $role => $min ) {
            if ( $current_balance > $min )
                $new_role = $role;
        }
    
        // Change users role if we have one
        if ( $new_role !== false )
            wp_update_user( array(
                'ID'   => $user_id,
                'role' => $new_role
            ) );
    
        return $reply;
    }

I may be missing something but it appears that your function will do what you want already.  You are testing the new balance against the min values for each category.  Whatever min value is identified as what s/b a new role you are assigning at the end already.

Add some echos to diagnose what is happening .  What does that extract line do for you here?

Change new role to be a blank (or assign 'contributor') to start.  Then assign the new role when your test finds one that fits.  If new role is not blank at the end of the loop then post it.

With a couple of db tables like this

Table: user                                    Table: role
+---------+----------+--------+                +---------+---------------+-----------+------------+
| user_id | username | points |                | role_id | role_name     | point_min | points_max |
+---------+----------+--------+                +---------+---------------+-----------+------------+
|       1 | John     |     66 |                |       5 | -             |         0 |        100 |
|       2 | Paul     |    101 |                |       6 | Contributor   |       101 |       1000 |
|       3 | George   |   3000 |                |       7 | Author        |      1001 |      10000 |
|       4 | Ringo    | 200000 |                |       8 | Editor        |     10001 |     100000 |
+---------+----------+--------+                |       9 | Administrator |    100001 |  999999999 |
                                               +---------+---------------+-----------+------------+

Then a simple query

SELECT username
     , rolename
FROM user u
     JOIN
     role r ON u.points BETWEEN r.points_min AND r.points_max;
     

does the job for you

+----------+---------------+
| username | rolename      |
+----------+---------------+
| John     | -             |
| Paul     | Contributor   |
| George   | Author        |
| Ringo    | Administrator |
+----------+---------------+

PS If you really want to do it in PHP then you can apply the same method to an array

$thresholds = array(
            '-'             => [0, 100],
            'contributor'   => [101, 1000],
            'author'        => [1001, 10000],
            'editor'        => [10001, 100000],
            'administrator' => [100001, 999999999]
        );
        
echo getUserRole(50000, $thresholds);       //--> editor


function getUserRole($current_balance, $thresholds)
{
    foreach ( $thresholds as $role => $range ) {
    
        if (  $range[0] <= $current_balance && $current_balance <= $range[1] ) {
             return $role;
        }    
    }
    return false;   
}
