php - MySQL 受影响的行 - 帮助

Question

当我尝试运行它时:

$s=mysql_query("INSERT INTO forum_topics (forum_id,userid,title,createtime,createip,last_post_user,last_post_userid,last_post_time) VALUES ('$forum_cat_id','$userid','$title','$time','$ip','{$userdata['username']}','$userid','$time')");
        if(mysql_affected_rows($s) == 0)
            return 7;

我收到以下错误:警告:

mysql_affected_rows(): supplied argument is not a valid MySQL-Link resource in "PATH/TO/FILE" on line 76

这是为什么？

编辑:(在我完成 var_dump 后，它返回了这个):

bool(true) string(0) "" Warning: mysql_affected_rows(): supplied argument is not a valid MySQL-Link resource in "PATH/TO/SITE" on line 77

Answer 1

您不需要将 $s 传递给 mysql_affected_rows()功能
