Answer 1

When routing to the URL http://index2.php/?user=2 , you can access the GET superglobal values as follows:

<?php $selected_user = $_GET['user'];/>

If you want this to be the value of your input you could do the following:

<input type="text" value="<?php echo $selected_user;?>">

Answer 2

Use Ajax to send data from one page to another.

On Index.php Page

 $user=$_GET['user'];
 $.ajax({  
        type: 'POST',  
        url: 'next_page.php', 
        data: { user: <?php echo $_GET['user']; ?> },
        success: function(response) {
        }
    });

On next_page.php

$user= $_POST['user'];
echo $user;
