I’ve tried on my wordpress site to group multiple products and I have no idea why but I can’t add products on cart.. I’ve tried to complete all the input for quantity, but nothing.. Any idea? On single product works..

Here is my grouped.php

<?php
/**
 * Grouped product add to cart
 *
 * @author      WooThemes
 * @package     WooCommerce/Templates
 * @version     2.1.7
 */

if ( ! defined( 'ABSPATH' ) ) exit; // Exit if accessed directly

global $product, $post;

$parent_product_post = $post;

do_action( 'woocommerce_before_add_to_cart_form' ); ?>

<form class="cart" method="post" enctype='multipart/form-data'>
    <div class="group_table">
        <?php
            foreach ( $grouped_products as $product_id ) :
                $product = wc_get_product( $product_id );
                $post    = $product->post;
                setup_postdata( $post );
                ?>
                    <div class="group-row">
                        <div class="quantity-row">
                            <?php if ( $product->is_sold_individually() || ! $product->is_purchasable() ) : ?>
                                <?php woocommerce_template_loop_add_to_cart(); ?>
                            <?php else : ?>
                                <?php
                                    $quantites_required = true;
                                    woocommerce_quantity_input( array( 'input_name' => 'quantity[' . $product_id . ']', 'input_value' => '0' ) );
                                ?>
                            <?php endif; ?>
