Hello,

I love that you have this plugin! It is desperately needed. However, I noticed that the user image will not sync on subsites in a multisite setup. I feel this is due to the file being stored in the main sites media folder, but not subsites. While I might be able to resolve this with a multisite shared media plugin, that is redundant and wastes server space.

Is there another workaround for this so that avatar images show up on multisite subsites?

Hi,

Please refer to this topic to get the field value from the main site and display it on the subsites with coding

Long,

Thank you for your helpful reply 🙂 I have been trying to figure this out based on the settings page reference you gave and the tutorial here: https://metabox.io/create-custom-avatar/

I have the upload field and image working beautifully on my main site but cannot seem to get the code to work to show avatars on my subsites. This is also an issue with the MB User Avatar v1.0 plugin you offer. Do you see anything in my code below that I am doing wrong?
```
add_filter( 'get_avatar' , 'my_custom_avatar' , 1 , 5 );
function my_custom_avatar( $avatar, $id_or_email, $size, $default, $alt ) {
    switch_to_blog( 1 );
    $user = false;
    if ( is_numeric( $id_or_email ) ) {
        $id = (int) $id_or_email;
        $user = get_user_by( 'id' , $id );
    } elseif ( is_object( $id_or_email ) ) {
        if ( ! empty( $id_or_email->user_id ) ) {
            $id = (int) $id_or_email->user_id;
            $user = get_user_by( 'id' , $id );
        }
    } else {
        $user = get_user_by( 'email', $id_or_email );
    }

    if ( $user && is_object( $user ) ) {
        $value = rwmb_meta( 'custom_avatar', array( 'object_type' => 'user' ), $user->data->ID ); 
        if ( $value ) {
            $avatar = "<img src='" . $value['url'] . "' class='avatar avatar-" . $size . " photo' alt='" . $alt . "' height='" . $size . "' width='" . $size . "' />";
        }
    }    
    return $avatar;
}
restore_current_blog();
```

Hi,

Did you try to use this sample code to get the image via guid?

Yes, I cannot seem to get that to work. The example code also uses groups and settings pages which don't seem to translate for me here.

Hi,

Here is the code that works on my end.
```
add_filter( 'get_avatar' , 'my_custom_avatar' , 1 , 5 );
function my_custom_avatar( $avatar, $id_or_email, $size, $default, $alt ) {
    $user = false;
    if ( is_numeric( $id_or_email ) ) {
        $id = (int) $id_or_email;
        $user = get_user_by( 'id' , $id );
    } elseif ( is_object( $id_or_email ) ) {
        if ( ! empty( $id_or_email->user_id ) ) {
            $id = (int) $id_or_email->user_id;
            $user = get_user_by( 'id' , $id );
        }
    } else {
        $user = get_user_by( 'email', $id_or_email );
    }

    if ( $user && is_object( $user ) ) {
        $id = get_main_site_id();
        switch_to_blog( $id );
        $value = rwmb_meta( 'custom_avatar', array( 'object_type' => 'user' ), $user->ID ); //return image ID
        $image = get_post( $value ); //get post by image ID 
        if ( $value ) {
            $avatar = "<img src='" . $image->guid . "' class='avatar avatar-" . $size . " photo' alt='" . $alt . "' height='" . $size . "' width='" . $size . "' />";
        }
    }    
    restore_current_blog();
    
    return $avatar;
}
```
You can add the code in the sub-site to get and show the user meta from the main site.

Aha! That did it! You are a wizard, thank you so much 😀

For anyone referring to this thread in the future, I had to create two separate snippets to get this to work.

First, for my main site I activated and used the exact snippet and instructions found in the tutorial here: https://metabox.io/create-custom-avatar/

Second, I used the snippet provided by Long just above and activated it on all my subsites.

Tip: If you don't have a way to manage your multisite snippets already, I used the free plugin from the WordPress repository called "snippets" because it allowed me to manage my snippets on my network site and then make them available across the network. I can choose which snippets to activate on each subsite.

So, code snippet #1 from the tutorial is active on my main network site. Snippet #2 provided by Long above is activated on all my subsites.
