send C# string to .PHP page

Question

After looking a bit around I came to this page. Here, I found some code to send a C# string to a PHP page.

However, after implementing it in my own program it did not work. Here is my code:

        private void executesend()
        {  
            using (WebClient client = new WebClient())
            {
                client.UploadString(url,"POST",keys);
            }
        }

For the PHP part, I have:

    <?php 
    mysql_connect("localhost", "", "") or die(mysql_error()); // Connect to database server(localhost) with username and password.
            mysql_select_db("dimittv89_dayz") or die(mysql_error()); // Select registration database.
            $name = $_GET["message"];
 if ( $_SERVER['REQUEST_METHOD'] == 'POST' )
{
    $name = file_get_contents('php://input');

    $opdracht = "INSERT INTO 'keys', (`key`) VALUES ('$name')";
    print $name;
}

if (mysql_query($opdracht)){ 
echo "succesfully registerd to the melloniax u wil now be returned to our main page";
 }
 else{
 echo "hey something went wrong there ! please try again in a minute";
 }


 ?>

In the same topic one of the users also said to try this:

php?fmessage=testtesttest"

and write down the output using

$name = $_GET["message"];
print $name;

This did not work either. Am I doing something wrong?

Thanks for the help already

Well sofar i found out its not the send value thats wrong but the get value :

Username = Registry.CurrentUser.OpenSubKey("Username", true);
Name = "" + Username.GetValue("Uid");

in the regedit menu it says that the value is a REG_BINARY, are these readable with getvalue ?

Can you elaborate a bit on how it doesn't work? What happens exactly? — Mr Lister

you probably didn't send to the correct php file, make sure you are writting the whole path for the php file, because the user that reply wanted to check if you're addressing to the correct page. — Orel Eraki

Can you included more of your code? It seems to me that you may have flow control problems in code. — Andrew Cox

I am guessing that the SQL statement is incorrect. Can you add to the answer the returned string from the client.UploadString(url,"POST",keys); You should be able to debug and just catch the returned value of the function. — Andrew Cox

use this code for c# and php :

private void executesend()
    {  

                HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);

                req.Method = "POST";
                string Data = "message="+keys;
                byte[] postBytes = Encoding.ASCII.GetBytes(Data);
                req.ContentType = "application/x-www-form-urlencoded";
                req.ContentLength = postBytes.Length;
                Stream requestStream = req.GetRequestStream();
                requestStream.Write(postBytes, 0, postBytes.Length);
                requestStream.Close();

                HttpWebResponse response = (HttpWebResponse)req.GetResponse();
                Stream resStream = response.GetResponseStream();

                var sr = new StreamReader(response.GetResponseStream());
                string responseText = sr.ReadToEnd();


            }
            catch (WebException)
            {

                MessageBox.Show("Please Check Your Internet Connection");
            }

}

and php

<?php 
    mysql_connect("localhost", "", "") or die(mysql_error()); // Connect to database server(localhost) with username and password.
            mysql_select_db("dimittv89_dayz") or die(mysql_error()); // Select registration database.

 if (isset($_POST['message']))
{
    $name = $_POST['message'];

    $opdracht = "INSERT INTO keys (key) VALUES ('$name')";
    print $name;
    if (mysql_query($opdracht)){ 
     echo "succesfully registerd to the melloniax u wil now be returned to our main page";
    }
    else{
     echo "hey something went wrong there ! please try`enter code here` again in a minute";
    }

}
