I am trying to make a validation for a form and if everything goes right it should go to the 2nd page, where it should take the information from the $_POST.

I was told that given the way I am doing it, $_POST would not work and I should try cURL. I tried to make it work, but somehow it does not work. It redirects correctly to the install2.php but its not passing any variables to it. What i am doing wrong?

My code is as follows:

<?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');
        }
    }
}
?>

それはポストフィールドを渡す方法ではありません:

curl_setopt ($ch, CURLOPT_POSTFIELDS, $username);

文字列を作成する必要があります：

$data = "username=$username&password=$password";

そしてそれを渡します：

curl_setopt ($ch, CURLOPT_POSTFIELDS, $data);

次に、 を使用して渡すパラメーターをより適切にエンコードしますurlencode()。

最後に、呼び出し時にパラメーターを渡します。

$response = curl_exec ($ch);

ただし、応答を読み取らず、ユーザーを次の場所にリダイレクトするだけです。

header ('location: install2.php');

今回は、問題を説明するパラメーターのない呼び出しです。
