嗨！所以我是pHp的超级初学者，我只是尽力去理解这一切。

我已经设法解决了我所接触到的每一个问题除了这一个。



mysql_num_rows（）期望参数1是资源，给定布尔值



我尝试运行此错误导致此错误

Hi! So I''m a super noob beginner in pHp and I''m just doing my best to understand all of this.
I''ve managed to fix every problem that I''ve come in contact with except this one.

mysql_num_rows() expects parameter 1 to be resource, boolean given

I get this error from trying to run this

if(isset($_POST['search_name'])) {
    $search_name = $_POST['search_name'];
    if(!empty($search_name)) {
        $query = "SELECT guild, focus, website, leader, members, voip, post, yes_no_website, single_multiple_leadersw FROM guilds WHERE guild LIKE '%".mysql_real_escape_string($search_name)."%'";

        $query_run = mysql_query($query);
                if (mysql_num_rows($query_run)>=1) {
                    while ($query_row = mysql_fetch_assoc($query_run))  {
                        echo $query_row['guild'];
                    }


                 }else{
                echo 'No results found.';
            }
        }
}

我不知道如何解决这个问题，我道歉如果我没有以正确的格式或其他东西发布。
