How to synchronize user profile fields in multisite?

1 Views

I’m using wordpress multisite. I installed Multisite user management plugin.

If a user register in my main sites then that user automatically added in all my sites.

My problem it doesn’t copy the profile datas. I don’t want my users to fill the same data in all 50 sites. So is there any code available to sync the datas?

I mean if a user fill the profile fields in main sites all sub sites should be updated with the same value. Likewise if the user edit the profile in site10.example.com it should be synced and updated in all sites. Is it possible?

Thanks

  1. This code works, but it’s only been tested in a localhost environment.

    There’s a function extracted from the plugin Multisite User Management, which is based on the get_blog_list function, that has been deprecated.

    No alternative available. For performance reasons this function is not recommended.

    The user meta has to be checked individually, i.e.: Aim, Jabber, etc.

    add_action( 'admin_init', 'wpse_38421_init');

function wpse_38421_init() 
{
    add_action( 'personal_options_update', 'wpse_38421_save_profile_fields' );
    add_action( 'edit_user_profile_update', 'wpse_38421_save_profile_fields' );
}

function wpse_38421_save_profile_fields( $user_id ) 
{
    
    $user_url = ( isset( $_POST['url'] ) && '' !== $_POST['url'] ) 
                ? $_POST['url'] : false;
                
    $user_aim = ( isset( $_POST['aim'] ) && '' !== $_POST['aim'] ) 
                ? $_POST['aim'] : false;
                
    $user_yim = ( isset( $_POST['yim'] ) && '' !== $_POST['yim'] ) 
                ? $_POST['yim'] : false;
                
    $user_jabber = ( isset( $_POST['jabber'] ) && '' !== $_POST['jabber'] ) 
                ? $_POST['jabber'] : false;

    $current_site = get_current_blog_id();
    $all_blogs = wpse_38421_get_blog_list( 0, 'all' );

    foreach ( $all_blogs as $key => $blog ) 
    { 
        if ( 
            is_user_member_of_blog( $user_id, $blog[ 'blog_id' ] ) 
            && $current_site != $blog[ 'blog_id' ] 
            )
            continue;

        switch_to_blog( $blog[ 'blog_id' ] );

        if ( $user_url ) 
            update_usermeta( $user_id, 'url', $user_url );
            
        if ( $user_aim ) 
            update_usermeta( $user_id, 'aim', $user_aim );
            
        if ( $user_yim ) 
            update_usermeta( $user_id, 'yim', $user_yim );
            
        if ( $user_jabber ) 
            update_usermeta( $user_id, 'jabber', $user_jabber );
    }
    
    switch_to_blog( $current_site );
}
