我在代码中收到此警告:
警告:mysql_fetch_array()期望 参数1是资源,字符串 给定的 C:\ xampp \ htdocs \ Join.php on 第69行
但我无法准确确定问题所在。 你能帮我看一下这段代码中的错误:
<?php
51. include("connect.php");
53. $email = mysql_query("select MemberEmail from members where MemberID= '$id' ");
54. while ($row = mysql_fetch_array($email))
55. {
57. $memEmail=$row['MemberEmail'];
}
62. $sql = mysql_query("select * from ninvite where recieverMemberEmail ='$memEmail' and viwed= '0' order by RoomID desc");
64. $num =mysql_num_rows($sql);
67. if ($sql and $num >0 )
{
69. while($row=mysql_fetch_array($sql))
{
71. $sender=$row['SenderMemberID'];
73. $room=$row['RoomID'];
77. $sql2 =mysql_query("select MemberName from members where MemberID ='$sender' ");
78. $sql1 =mysql_query("select RoomName,RoomLogo from rooms where RoomID ='$room' ");
79. while($row=mysql_fetch_array($sql2))
{
$mem =$row['MemberName'];
}
84. while($rows=mysql_fetch_array($sql1))
{
$Ro =$rows['RoomName'];
$logo = $rows['RoomLogo'];
}
89. ?>

$R=mysql_query($sql);
}

} } }
?>
非常感谢!

不应viwed
为viewed
?
select *
from ninvite
where recieverMemberEmail = '$memEmail'
and viewed = '0'
order by RoomID desc

我很惊讶你没有在第64行(也期望资源)上收到错误。第62行的SQL在数据库中生成错误。暂时将其更改为:
$sql = mysql_query("select * from ninvite where recieverMemberEmail ='$memEmail' and viwed= '0' order by RoomID desc") or die(mysql_error());
并检查打印的错误消息。
答案 2 :(得分:0)
$sql = mysql_query("select * from ninvite where recieverMemberEmail ='$memEmail' and viwed= '0' order by RoomID desc");
我认为一定是这样的:
$sql = mysql_query("select * from ninvite where recieverMemberEmail ='".$memEmail."' and viwed= '0' order by RoomID desc");

第67行应该是:
if ($sql && $num >0 )
不是
if ($sql and $num >0 )
答案 4 :(得分:0)
你的问题在线:
$sql = ("DELETE FROM ninvite WHERE RoomID = '$room'");
因为你没有关闭while循环的括号,所以你打开了第70行。
