Answer 1

You can first check the $_SERVER['REQUEST_METHOD'] if it is a 'GET' and check if all your expected parameters are set. Then you can use http_build_query to build your url and use header to go to your url.

if (
    $_SERVER['REQUEST_METHOD'] === 'GET' &&
    isset($_GET['buyer_first_name']) &&
    isset($_GET['buyer_last_name']) &&
    isset($_GET['buyer_email']) &&
    $_GET['order_id']
) {
    $params = array(
        'k' => 'test',
        'action' => 'add',
        'r' => $_GET['order_id'],
        'n' => $_GET['buyer_email']
    );

    $url = 'www.mydomain.com/query.php?' .  http_build_query($params);
    header("location:" . $url);
}

Answer 2

header("location: www.mydomain.com/query.php?k=test&action=add&r=$orderid&n=$email");

如果您使用header（'location ...，请确保在页面上看不到任何内容，否则将收到“已发送标题，输出开始...。”错误。

This should pretty much do what you are trying to accomplish

<?php
    if( $_SERVER['REQUEST_METHOD']=='GET' && isset( $_GET['buyer_first_name'],$_GET['buyer_last_name'],$_GET['buyer_email'],$_GET['order_id'] ) ){

        header( "location: www.mydomain.com/query.php?k=test&action=add&r={$_GET['order_id']}&n={$_GET['buyer_email']}" );

    }
?>

Answer 4

http_build_query is a cool function

$parameters = array(
  'k'      => 'test',
  'action' => 'add',
  'r'      => $orderid,
  'n'      => $email,
);

$target = 'www.mydomain.com/query.php';
$url = $target.'?'.http_build_query($parameters);
header("location: $url");

Answer 5

You can use as below :

<?php
$fname='';$lname='';$email='';$orderid='';
if(isset($_GET['buyer_first_name']))
    $fname=stripslashes($_GET['buyer_first_name']);
if(isset($_GET['buyer_last_name']))
    $lname=stripslashes($_GET['buyer_last_name']);
if(isset($_GET['buyer_email']))
    $email=stripslashes($_GET['buyer_email']);
if(isset($_GET['order_id']))
    $orderid=stripslashes($_GET['order_id']);
$fullurl = "www.mydomain.com/query.php?k=test&action=add&r=".$orderid."&n=".$email;
header("location:".$fullurl);
?>

$querystring = "www.websitedomain.com/redirect.php?".$_SERVER['QUERY_STRING'];
header('location:'.$querystring);
