简单的标头位置不重定向

Question

下面是一个简单的脚本，用于从工作正常的表中删除信息，但这不会重定向到我需要它去的地方。有任何想法吗？之后我也尝试过使用die(); 等。

<?php
$dbservername = "xxxxx";
$dbusername = "xxxxx";
$dbpassword = "xxxxx";
$conn = mysql_connect($dbservername, $dbusername, $dbpassword);
$db  = mysql_select_db("sxxxxx", $conn);
if (!$conn) { die('Could not connect: ' . mysql_error()); }
?>

---

<?php
session_start();
include"connect_db.php"; (this include, includes the above connection to db)

$content_id=$_GET['content_id'];
$username=$_SESSION['username'];



$sql = "DELETE FROM `user_blogs` WHERE `id`='".$content_id."' AND `username`='".$username."'";

$res = mysql_query($sql) or die(mysql_error());         

header("location: user_page.php");

?>

Answer 1

试试这可能是条件问题...

$res = mysql_query($sql) or die(mysql_error());     

if($res){    

header("location: user_page.php");

}else{}
