Plz帮助我不知道这个功能有什么问题....
$gsql = "SELECT * FROM posts WHERE group='$group_name' ORDER BY postdate DESC LIMIT 0,20";
$gquery = mysqli_query($db_conx, $gsql);
$gstatusnumrows = mysqli_num_rows($gquery);
while ($grow = mysqli_fetch_array($gquery, MYSQLI_ASSOC)) {
它一直在说这个错误: -
Warning: mysqli_num_rows() expects parameter 1 to be mysqli_result, boolean given in D:\group.php on line 3
Warning: mysqli_fetch_array() expects parameter 1 to be mysqli_result, boolean given in D:\group.php on line 5
