Unable to get $_GET values from form

I cannot retrieve the $_GET['id'] nor $_GET['action'] from a form and input in this page:

<?php
include "common.php";
var_dump($_GET['quantity']);
var_dump($_GET['action']);
var_dump($_GET['id']);

?>
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>es6.1.6</title>
    <style type="text/css">
        input {
            margin: 10px;
        }
    </style>
</head>
<body>
<ul>
    <?php
    for($i=1; $i<=sizeof($names); $i++) {
        echo "<form method='get' action='shop.php?action=add&id=$i'>";
        echo "<li><a href='description.php?item=$i'> ",$names[$i],"</a></li>";
        echo "<input type='number' name='quantity'>";
        echo "</form>";
    }
    ?>
</ul>

<br><br>
<form action="summary.php">
    <input type="submit" value="Add to cart">
</form>

</body>
</html>

only $_GET['quantity'] will be set after inserting a number and pressing Enter into any input form

try adding action and id as hidden input fields with the values you need

edit: change your code to look like this:

for($i=1; $i<=sizeof($names); $i++) {
        echo "<form method='get' action='shop.php'>";
        echo "<li><a href='description.php?item=$i'> ",$names[$i],"</a></li>";
        echo "<input type='number' name='quantity'>";
        echo "<input type='hidden' name='action' value='add'>";
        echo "<input type='hidden' name='id' value='" . $i . "'>";
        echo "</form>";
    }
