我正在尝试对表单进行验证，如果一切顺利，它应该转到第二页，在那里它应该从$_POST中获取信息。
有人告诉我，按照我现在的做法，$_POST不起作用，我应该试试cURL。我试着让它发挥作用，但不知怎么的，它不起作用。它正确地重定向到install2.php，但没有向它传递任何变量。我做错了什么？
我的代码如下：
<?php
//If the person pressed summit check for the information submited. If everything is correct move to the next page.
if (isset($_POST['submit']))
{
// declare Variables
$username = $_POST['username'];
$password = $_POST['password'];
$server = $_POST['server'];
$message = "The following fields are empty: ";
//Step 1 : Check if username & server are empty and if they are return the correct error
if (empty($username) || empty($server) )
{
if (empty($username)) {
$message .= "Username";
}
if (empty($password)) {
$message .= " Password";
}
if (empty($server)) {
$message .= " Server";
}
}
else
{
//Step 2: Attempt to connect to the DB with the information provided. if not sucessful return to correct error to the user.
@$connection = mysql_connect($server,$username,$password);
if (!$connection)
{
$message = "Please check your details. the script was unable to connect to the db.";
}
else
{
//Step 3: Since the connection was stablished successfuly with the information provided then send the login details tot he next page
// NOTE: For porpuses of this script I am only passing 1 variable... to make my life easier
$ch = curl_init ();
curl_setopt ($ch, CURLOPT_URL, 'http://localhost/install2.php');
curl_setopt ($ch, CURLOPT_POST, TRUE);
curl_setopt ($ch, CURLOPT_POSTFIELDS, $username);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, TRUE);
$response = curl_exec ($ch);
curl_close ($responde);
header ('location: install2.php');
}
}
}
?>
这不是传递post字段的方法：
curl_setopt ($ch, CURLOPT_POSTFIELDS, $username);
您应该创建一个字符串：
$data = "username=$username&password=$password";
并通过：
curl_setopt ($ch, CURLOPT_POSTFIELDS, $data);
第二，使用urlencode()对您传递的参数进行更好的编码。
最后，当你调用时，它确实会传递参数
$response = curl_exec ($ch);
但是，然后你不读取响应，只是将用户重定向到：
header ('location: install2.php');
这一次是一个没有参数的调用，可以解释您的问题。
我注意到您的变量名不一样。
$reponse and $responde
$response = curl_exec ($ch);
curl_close ($responde);
header ('location: install2.php');
