Buddypress更改头像

问题描述

我需要在wordpress（特定的BuddyPress）上自定义上传头像页面。我找到并实现了一些已有的代码，但无法正常工作。

它会在“ /wp-admin/profile.PHP”更改头像，但不会在“ /wp-admin/users.PHP?page=bp-profile-edit”更改头像。

global $current_user;
$user_id = get_current_user_id();

/* PHOTO */

$user_last = get_user_Meta($user_id);
//$unserialize = unserialize($user_last['simple_local_avatar'][0]);
class Simple_Local_AvataRSSss {
    private $user_id_being_edited,$avatar_upload_error,$remove_nonce,$avatar_ratings;
    public $options;        
    public function unique_filename_callback( $dir,$name,$ext ) {
        $user = get_user_by( 'id',(int) $this->user_id_being_edited ); 
        $name = $base_name = sanitize_file_name( $user->display_name . '_avatar_' . time() );
        // ensure no conflicts with existing file names
        $number = 1;
        while ( file_exists( $dir . "/$name$ext" ) ) {
            $name = $base_name . '_' . $number;
            $number++;
        }

        return $name . $ext;
    }
    private function assign_new_user_avatar( $url_or_media_id,$user_id ) {
        // delete the old avatar
        $this->avatar_delete( $user_id );   // delete old images if successful
        $Meta_value = array();
        // set the new avatar
        if ( is_int( $url_or_media_id ) ) {
            $Meta_value['media_id'] = $url_or_media_id;
            $url_or_media_id = wp_get_attachment_url( $url_or_media_id );
        }
        $Meta_value['full'] = $url_or_media_id;
        update_user_Meta( $user_id,'simple_local_avatar',$Meta_value );   // save user @R_686_4045@ion (overwriting old)
    }

    public function avatar_delete( $user_id ) {
        $old_avatars = (array) get_user_Meta( $user_id,true );
        if ( empty( $old_avatars ) )
            return;
        // if it was uploaded media,don't erase the full size or try to erase an the ID
        if ( array_key_exists( 'media_id',$old_avatars ) )
            unset( $old_avatars['media_id'],$old_avatars['full'] );
        if ( ! empty( $old_avatars ) ) {
            $upload_path = wp_upload_dir();
            foreach ($old_avatars as $old_avatar ) {
                // derive the path for the file based on the upload directory
                $old_avatar_path = str_replace( $upload_path['baseurl'],$upload_path['basedir'],$old_avatar );
                if ( file_exists( $old_avatar_path ) )
                    unlink( $old_avatar_path );
            }
        }

                }

                return;

            $this->assign_new_user_avatar( $avatar['url'],$user_id );
