wordpress 自定义用户头像同步前端后台-www.88531.cn资享网

开发的部分主题里会有前端头像上传的功能，那么怎么才能让头像同步后台与前端呢？我们这里去除默认的头像，用固定的某张图片代替，大大加快加载速度。

代码如下：

add_filter('get_avatar', 'MBT_get_avatar', 10, 3);  function MBT_get_avatar($avatar, $id_or_email, $size){   $default_avatar = get_bloginfo('template_url').'/img/avatar.png'; //默认头像   if(is_object($id_or_email)) {   if($id_or_email->user_id != 0) {   $email = $id_or_email->user_id;   $user = get_user_by('email',$email);   $user_avatar = get_user_meta($id_or_email->user_id, 'avatar', true);   if($user_avatar)   return '<img src="'.$user_avatar.'" class="avatar avatar-'.$size.' photo" width="'.$size.'" height="'.$size.'" alt="'.$user->display_name .'" />';   else   return '<img src="'.$default_avatar.'" class="avatar avatar-'.$size.' photo" width="'.$size.'" height="'.$size.'" alt="'.$user->display_name .'" />';      }elseif(!empty($id_or_email->comment_author_email)) {   //$user = get_user_by('email', $id_or_email->comment_author_email);   //$email = !empty($user) ? $user->ID : $id_or_email->comment_author_email;   return '<img src="'.$default_avatar.'" class="avatar avatar-'.$size.' photo" width="'.$size.'" height="'.$size.'" alt="'.$user->display_name .'" />';   }   }else{   if(is_numeric($id_or_email) && $id_or_email > 0){   $user = get_user_by('id',$id_or_email);   $user_avatar = get_user_meta($id_or_email, 'avatar', true);   if($user_avatar)   return '<img src="'.$user_avatar.'" class="avatar avatar-'.$size.' photo" width="'.$size.'" height="'.$size.'" alt="'.$user->display_name .'" />';   else   return '<img src="'.$default_avatar.'" class="avatar avatar-'.$size.' photo" width="'.$size.'" height="'.$size.'" alt="'.$user->display_name .'" />';   }elseif(is_email($id_or_email)){   $user = get_user_by('email',$id_or_email);   $user_avatar = get_user_meta($user->ID, 'avatar', true);   if($user_avatar)   return '<img src="'.$user_avatar.'" class="avatar avatar-'.$size.' photo" width="'.$size.'" height="'.$size.'" alt="'.$user->display_name .'" />';   else   return '<img src="'.$default_avatar.'" class="avatar avatar-'.$size.' photo" width="'.$size.'" height="'.$size.'" alt="'.$user->display_name .'" />';   }else{   return '<img src="'.$default_avatar.'" class="avatar avatar-'.$size.' photo" width="'.$size.'" height="'.$size.'"  />';   }   }   return $avatar;  }
