One possibility is to use an ajax request to send the id of the request that was clicked to the server. To avoid having to change many things in your code you can use the fetch api (available in newer browsers), instead of having to use the jquery plugin.

Basically you should add the following javascript block before closing the tag body of the file Order screen:

<script type="text/javascript">
    //retorna um vetor com todos os radio buttons com name igual a pedido
    var radios = document.getElementsByName('pedido');

    //percorre o array de radio button adicionando um evento para quando houver um click 
    //em um deles
    for(var i = 0; i < radios.length; i++){

        radios[i].onclick = function(){
            //quando um radio button for clicado, envia o id dele par ao servidor
            enviarPedidoId(this.value);
        };
    }
    function enviarPedidoId(id_pedido){
        var parametros = { 
        method: 'POST',
        body: 'id_pedido=' + id_pedido,
        headers: new Headers({
           'Content-Type': 'application/x-www-form-urlencoded'
        }) 
        };

        //pagina em php para receber o id do pedido e armazenar na sessao
        fetch('recebePedido.php', parametros)
        .then(function(response) {

        }); 
    }
</script>

And create a new php file (not to mess with what is done). In the above example, a file called receive.php was created, with the following content::

<?php
session_start();

$_SESSION['id_pedido'] = $_POST['id_pedido'];
?>
