PHP Using Post method to transfer variable from a page to a third Page

Question

I have a Login Page with the following Code;

                <p> Login  Name</p>
                <p>
           <input type="text" 
                  name="username" id="username">


    <input type="submit" name="submit" value="submit">


        </p>
            <p>
              <label for="password">Password<br />
                <br />
              </label>
              <input name="password" 
              type="password" id="password"></input>

            </p>

        <p>

          <input type="submit" value="Login"/>
          <input type="reset" value="Reset"/>
          </p>
        <p><br />

and after capturing

i have also this code using the inputs

   require('config\db.php');
  session_start();
  // If form submitted, insert values into the database.
  if (isset($_POST['username'])){
  //$username1 = $_POST['username1'];;
    $username = $_POST['username'];
    $password = $_POST['password'];
    $username = stripslashes($username);
    $username = mysql_real_escape_string($username);
    $password = stripslashes($password);
    $password = mysql_real_escape_string($password);

I open a Page which has some options on logging in . I select one option on that page using radio buttons. It opens a third page.

I want to display the User Name captured on the first page.

How can i do this? Any help will be highly appreciated.

**Warning**: You are using [an **obsolete** database API](http://stackoverflow.com/q/12859942/19068) and should use a [modern replacement](http://php.net/manual/en/mysqlinfo.api.choosing.php). — Quentin, Oct 28 '15 at 15:16
Since you'll probably want the username again sometime try http://php.net/manual/en/book.session.php — AbraCadaver, Oct 28 '15 at 15:18
don't blindly strip slashes from text. You're simply ASSUMING that magic_quotes is enabled, and you risk mangling a user's password if they really do have a backslash in it. — Marc B, Oct 28 '15 at 15:18

You have to store it somewhere.

A hidden input in the form in the second page is pretty reliable.

A session is a common choice, although subject to race conditions.

Store that user name in session
Then you can use it anywhere

To use session to should write session_start(); which you have done.

Now just store your username in session.

$_SESSION['username']=$username;

echo you can print it by just

echo $_SESSION['username'];

You need to start the session using session_start(); [check this](http://stackoverflow.com/questions/9650090/undefined-variable-session) – Swap Oct 30 '15 at 13:42
