Question

您好我正在尝试在网址中设置什么，并从中形成一个sql select语句

然而，这种情况不断出现：警告：mysql_fetch_array（）要求参数1为资源，在第76行的C：\ xampp \ htdocs \ JobBoard \ viewjobs.php中给出布尔值

 include 'db_connect.php';
 $addedquery = '';

{
 //$nursingjob = $_GET["nursing"];
 $addedquery = "AND nursing=yes $addedquery";     <<<<<<<<---------
