我想在用户注销/登录时这样做（&N）；查看其他用户配置文件“仅查看联系人卖家”按钮（&A）；当用户登录查看自己的个人资料时，会显示“查看收件箱”&；编辑我的个人资料按钮。这是一个屏幕，显示以管理员身份登录的用户查看属于flamez的配置文件，并看到错误的按钮https://www.dropbox.com/s/lifcq06y54jol7z/Screenshot%20of%20error.png?dl=0
以下是我目前掌握的代码：
<style>
a.view_inbox_btn:link, a.view_inbox_btn:visited{

display: inline-block;

如果页面作者是需要比较的用户，则可以使用get\\u the\\u author\\u meta（\'id\'）。如果没有，也许可以从url获取尼克，并从其id在数据库中搜索。
$currentUserId = get_current_user_id();
$lastPartOfUrl = \'flamez\'; // Get from the url, as in your screenshot
$table = $wpdb->prefix.\'users\';
$page_owner_id = $wpdb->get_var("select ID from $table where user_login=\'$lastPartOfUrl\'");
//Then compare
if($currentUserId === $page_owner_id){
//We show the edit profile button
}else{
//We show the other button
}
希望这有助于更好地理解。注意清理$lastPartOfUrl变量，因为它会破坏您的代码或将您暴露于
SQL injection.
[编辑]如果您不知道url的最后一部分，可以按如下方式提取：
$currentPage = $_SERVER[\'REQUEST_URI\'];
$parts = explode(\'?\',$currentPage);
$lastPartOfUrl = basename(trim($parts[0],\'/\'));
