Question

这是我的代码...... 对于功能
它没有更新激活。

    $email = mysql_real_escape_string($email);
    $email_code = mysql_real_escape_string($email_code);


    mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `email` = '$email' AND `email_code` = '$email_code' AND `activated` = 0"), 0) == 1)
    if(mysql_query("UPDATE `users` SET `activated` = 1 WHERE `email` = '$email'")){
        return true;
        }
    else{

您应该在放置变量时删除引号，例如：

"SELECT COUNT(`user_id`) FROM `users` WHERE `email` = " 
+ $email 
+ " AND `email_code` = " 
+ $email_code 
+ " AND `activated` = 0"

"UPDATE `users` SET `activated` = 1 WHERE `email` = " + $email
