Can I post my get request to another page?

See more:

PHP

so I have this get request on reservation.php

<h2>Reserveren <?php echo $_GET['naam'];?>

'
on this page I have a form that users can fill in. if they hit submit they go to reservationback.php and this will insert all information in the db

now I want to also insert the ID that corresponds with the $_GET naam (a.k.a name) that I have on reservation.php
how do I do this?

reservationback.php

<?php
include "config.php";
if ($_POST['submit']){
    $naam =  $_POST['naam'];
    $email = $_POST['email'];
    $telefoonnummer = $_POST['telefoonnummer'];
    $huis_Naam = "huisnaam"; // This is where I want the information from the $_GET request

    $sql = "INSERT INTO huurder (naam, email, telefoonnummer, huis_Naam) VALUES (?, ?, ?, ?)"; 
    if($stmt = $conn->prepare($sql)){
        $stmt->bind_param('ssis', $naam, $email, $telefoonnummer, $huis_Naam);
        if(!$stmt->execute())
        {
            echo 'Het uitvoeren van de query is mislukt: '.$stmt->error.' in query: '.$sql;
        }else{
            echo "Het uitvoeren was een succes!";
        }
    }
}else{
    echo "random test";
}

What I have tried:

things I tried searching

post my $get to another page php

$_get to another page PHP

I also tried $huis_naam = $_GET['naam']; but that gives undefined array key (obviously because I'm not putting naam in to the url)
