Question

我正在努力应该是一个简单的查询，尽管互联网搜索等我仍然无法找到有用的东西。这是我的代码 -

＆＃13;

<?php require_once('../Connections/spotting.php'); 	
include_once ("../auth.php");	
include_once ("../authconfig.php");	
include_once ("../check.php");	

$username = $check["uname"];
$query = "SELECT * FROM spotting WHERE uname='$username'";
$result = mysql_query($query) or die ('unable to run R1: ' .mysql_error());
$count = mysql_num_rows($result);

$query2 = "SELECT spots FROM authuser WHERE uname='$username'";
$result2 = mysql_query($query2) or die ('unable to run R2: ' .mysql_error());
$spotval = $result2['spots'];

echo "you have $count Records </p>" ;

if($count==$result2) 
{
   header( 'Location: http://www.mysite.co.uk/upgrade.php' ) ;
}
else {
echo "You are below your limit $result2";
}
?>

＆＃13;

有人能指点我吗？

Answer 1

根据代码，您将第一个查询的总记录与第二个查询的记录进行比较。

你应该做

//OLD code
$result2 = mysql_query($query2) or die ('unable to run R2: ' .mysql_error());
$count1 = mysql_num_rows($result2); 
if($count == $count1)

根据您的评论，您应该进行以下更改

 if($count == $spotval)

和header already sent问题。删除echo "you have $count Records </p>" ;。因为如果要重定向页面，则不需要这样做。

Answer 2

如果您只想重定向到其他网页，请尝试以下方法：echo "<script>window.location.assign('goToThisPage.html');</script>"

Answer 3

尝试获取第二个查询的行数并进行检查

<?php require_once('../Connections/spotting.php');  
include_once ("../auth.php");   
include_once ("../authconfig.php"); 
include_once ("../check.php");  

$username = $check["uname"];
$query = "SELECT * FROM spotting WHERE uname='$username'";
$result = mysql_query($query) or die ('unable to run R1: ' .mysql_error());
$count = mysql_num_rows($result);

$query2 = "SELECT spots FROM authuser WHERE uname='$username'";
$result2 = mysql_query($query2) or die ('unable to run R2: ' 
.mysql_error());

$spotval = $result2['spots'];
$count2 = mysql_num_rows($result2);

echo "you have $count Records </p>" ;

if($count==$count2) 
{
   header( 'Location: http://www.mysite.co.uk/upgrade.php' ) ;
}
else {
  echo "You are below your limit $result2";
}
?>
