登录信息页面未重定向
[英]Login Info Page Not Redirecting
问题描述
I am having trouble redirecting my code to another page after a correct username/password has been submitted. 
提交正确的用户名/密码后，我无法将代码重定向到另一个页面。 After I enter the username/password and hit submit, the page does not redirect. 输入用户名/密码并单击“提交”后，页面不会重定向。
The page just reloads and clears the field inputs (even though it's a sticky form), and stays at the same page, except the URL adds ?submit=Submit to the end of the URL.. 该页面只是重新加载并清除字段输入（即使它是粘性表单），并停留在同一页面上，只是URL的末尾添加了?submit=Submit 。
I am not getting any mysql errors - the database is connecting fine at the query that matches the row with the username/password combo seems to be going through. 我没有收到任何mysql错误-在与用户名/密码组合匹配的行查询中，数据库连接正常。
It should be looping through the database, checking if the username/password combo exists, and redirecting to the specified page. 它应该遍历数据库，检查用户名/密码组合是否存在，并重定向到指定的页面。 I'm not sure what I'm not seeing / missing here that keeps the page from redirecting. 我不确定我在这里什么看不到/缺少什么，从而使页面无法重定向。 Any input would be greatly appreciated. 任何投入将不胜感激。

<?php
define('DB_LOCATION', 'x');
define('DB_USERNAME', 'x');
define('DB_PASS', 'x');
define('DB_NAME', 'x');
$dbc = mysqli_connect(DB_LOCATION, DB_USERNAME, DB_PASS, DB_NAME)
or die('Error connecting to database');
$error_message= "";
if (isset($_POST['submit'])) {
$user_name = $_POST['user'];
$user_password= $_POST['pass'];
// ADD QUERY TO CHECK IF USER/PASS COMBO IS CORRECT
if(!empty($user_name) && !empty($user_password)) {
$query = "SELECT * FROM employees WHERE username='$user_name' and password='$user_password'";
$result = mysqli_query($dbc, $query)
or die ('Error querying username/password request');
if(mysqli_num_rows($result) == 1) {
$user_name = $row['user'];
$user_password = $row['pass'];
header("Location: www.mysite.com ");
} // end if rows
else {
$error_message = "You were not able to log in";
} // end else
} // end query

删除<form> ，就在<div id="table2"> ，还要删除<form> </form> 。

Remove <form> and </form> just before <div id="table2"> but i say you create a simple function which handles the redirects like below. 在<div id="table2">之前删除<form>和</form> ，但是我说您创建了一个简单的函数来处理如下所示的重定向。
why don't you try something like this which creates a function for the redirect. 为什么不尝试这样的操作来创建重定向功能。
function Redirect($url, $permanent = false)
{
header('Location: ' . $url, true, $permanent ? 301 : 302);
exit();
}
Redirect('Location: www.mysite.com', false);
