下载一个 omegle 克隆时。这当然写得不好,所以关键文件中有一个错误。如果您想查看,这里是网站。我得到的错误是Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /home/a1687121/public_html/listenToReceive.php on line 11
这里是文件:
<?php
$userId=$_REQUEST["userId"];
$msg ="";
$randomUserId;
include ('config.inc.php');
include ('database.inc.php');
$result=mysql_query("SELECT * FROM chats WHERE userId = $userId ");
if (mysql_num_rows($result) > 0)
{
$result=mysql_query("SELECT * FROM msgs WHERE randomUserId = $userId ORDER BY sentdate limit 1");
$id =0;
while ($row=mysql_fetch_array($result))
{
$id = $row["id"];
$msg =$row["msg"];
$randomUserId=$row["userId"];
}
if ($id != 0)
{
mysql_query ("DELETE FROM msgs WHERE id = $id ");
mysql_query ("INSERT INTO oldMsgs(userId,randomUserId,msg) VALUES( $randomUserId,$userId,'$msg'); ");
}
}
else
{
echo "||--rut roh!--||";
}
mysql_close ($con);
echo $msg;
?>
我检查了一百万次。我找不到任何错误。谢谢!
$result=mysql_query("SELECT * FROM chats WHERE userId = $userId ");
// add the error check
if (!$result) {
die('ERROR: ' . mysql_error());
}
