Hello,

I would like to add the class ‘thumbnail’ to the group avatar with this filter but for some reason it returns an error saying “Illegal string offset ‘class’ “. What could be the reason ?

function.php :

// Add class to Group avatar image
  function bp_add_class_thumbnail_group_avatar( $avatar ) {
  $avatar['class'] .= ' thumbnail';
  return $avatar;
	}
	
add_filter( 'bp_get_group_avatar', 'bp_add_class_thumbnail_group_avatar' );
 

The original class is set by the function bp_core_fetch_avatar inside bp_get_group_avatar but it is not clear for me how to address this sub-function.

If somebody have an idea,
Thank you

	function bp_get_group_avatar( $args = '' ) {
		global $groups_template;

		// Bail if avatars are turned off.
		if ( bp_disable_group_avatar_uploads() || ! buddypress()->avatar->show_avatars ) {
			return false;
		}

		// Parse the arguments
		$r = bp_parse_args( $args, array(
			'type'   => 'full',
			'width'  => false,
			'height' => false,
			'class'  => 'avatar',
			'id'     => false,
			'alt'    => sprintf( __( 'Group logo of %s', 'buddypress' ), $groups_template->group->name )
		) );

		// Fetch the avatar from the folder
		$avatar = bp_core_fetch_avatar( array(
			'item_id'    => $groups_template->group->id,
			'title'      => $groups_template->group->name,
			'avatar_dir' => 'group-avatars',
			'object'     => 'group',
			'type'       => $r['type'],
			'alt'        => $r['alt'],
			'css_id'     => $r['id'],
			'class'      => $r['class'],
			'width'      => $r['width'],
			'height'     => $r['height']
		) );

		// If No avatar found, provide some backwards compatibility
		if ( empty( $avatar ) ) {
			$avatar = '<img src="' . esc_url( $groups_template->group->avatar_thumb ) . '" class="avatar" alt="' . esc_attr( $groups_template->group->name ) . '" />';
		}
