Woocommerce Ajax Add cart not working

Question

In woocommerce ajax add to cart method not adding when cart is empty, if cart contains something then my ajax function adds but if cart is empty it doesn't add. And no error.

Here is the link. PHP add cart function:

function add_custom_product_meta() {
    global $woocommerce, $wpdb;

    $item_id = isset($_POST['item_id']) ? apply_filters( 'woocommerce_add_to_cart_product_id', absint( $_POST['item_id'] ) ) : FALSE;
    $quantity = empty( $_POST['quantity'] ) ? 1 : wc_stock_amount( $_POST['quantity'] );
    $passed_validation = apply_filters( 'woocommerce_add_to_cart_validation', true, $item_id, $quantity );
    $product_status    = get_post_status( $item_id );

    $variation_id = isset($_POST['variation_id']) ? $_POST['variation_id'] : 0;
    $atributes = isset($_POST['atributes']) ? $_POST['atributes'] : 'Small';
    $attribute_pa_macaroons = isset($_POST['attribute_pa_macaroons']) ? $_POST['attribute_pa_macaroons'] : FALSE;

    if($attribute_pa_macaroons && $passed_validation && $woocommerce->cart->add_to_cart( $item_id, $quantity, $variation_id, array( 'attribute_size' => $atributes,  "macaroons" => $attribute_pa_macaroons))){

        //$added = $woocommerce->cart->add_to_cart( $item_id, $quantity, $variation_id, array( 'attribute_size' => $atributes,  "macaroons" => $attribute_pa_macaroons));

        do_action( 'woocommerce_ajax_added_to_cart', $item_id );

        if ( get_option( 'woocommerce_cart_redirect_after_add' ) == 'yes' ) {
            wc_add_to_cart_message( $item_id );
        }

        WC_AJAX::get_refreshed_fragments();

        echo json_encode(array(
            'atributes' => $atributes,
            'macaroons' => $attribute_pa_macaroons,
            'product_added' => TRUE,
            'ajax_complete' => TRUE,
            'posted' => isset($_POST['item_id']) ? $woocommerce->cart : 'item_id is empty'
        ));
        wp_die();
    }

    echo json_encode(array(
        'product_id' => FALSE,
        'product_added' => FALSE,
        'ajax_complete' => TRUE,
        'posted' => $attribute_pa_macaroons
    ));
    wp_die();
}

Javascript Ajax call:

$.ajax({
                        type : 'post',
                        dataType : 'json',
                        url : woocommerce_params.ajax_url,
                        data : {
                            'action' : 'elephas_addtocart_box',
                            'item_id' : itemID,
                            'quantity' : quantity,
                            'variation_id' : variathionID,
                            'atributes' : atributes,
                            'attribute_pa_macaroons' : itemData
                        }
                    })
                    .done(function(response){
                        if(response.ajax_complete){
                            document.location.reload(true);
                        }
                    })
                    .error(function(error){
                        console.log(error);
                    })
                    .always(function(response){
                        if(response.ajax_complete){
                            document.location.reload(true);
                        }
                    });

I think your php add_to_cart function not setting cart cookies, you can do this manually by adding this line inside the if condition before

//$added 

line

add this line

do_action( 'woocommerce_set_cart_cookies', TRUE );

this will set cart cookies.
