添加到购物车并重定向到 WooCommerce 中默认变量产品的结帐

Question

我正在尝试 LoicTheAztec 的以下代码 - Add to cart and redirect to checkout for variable products in WooCommerce

现在，问题是每当我在产品编辑器中设置默认变体的情况下单击“立即购买”按钮时，代码都无法正常工作。

在这种情况下，“立即购买”网址变为 …/?addtocart=0&quantity=n

我正在使用的主题 - 巴塞尔

有什么解决办法吗？

尝试了 LoicTheAztec 的代码。

function add_custom_addtocart_and_checkout() {
    global $product;

    $addtocart_url = wc_get_checkout_url().'?add-to-cart='.$product->get_id();
    $button_class  = 'single_add_to_cart_button button alt custom-checkout-btn';
    $button_text   = __("Buy & Checkout", "woocommerce");

    if( $product->is_type( 'simple' )) :
    ?>
    <script>
    jQuery(function($) {
        var url    = '<?php echo $addtocart_url; ?>',
            qty    = 'input.qty',
            button = 'a.custom-checkout-btn';

        // On input/change quantity event
        $(qty).on('input change', function() {
            $(button).attr('href', url + '&quantity=' + $(this).val() );
        });
    });
    </script>
    <?php

    elseif( $product->is_type( 'variable' ) ) : 

    $addtocart_url = wc_get_checkout_url().'?add-to-cart=';
    ?>
    <script>
    jQuery(function($) {
        var url    = '<?php echo $addtocart_url; ?>',
            vid    = 'input[name="variation_id"]',
            pid    = 'input[name="product_id"]',
            qty    = 'input.qty',
            button = 'a.custom-checkout-btn';

        // Once DOM is loaded
        setTimeout( function(){
            if( $(vid).val() != '' ){
                $(button).attr('href', url + $(vid).val() + '&quantity=' + $(qty).val() );
            }
        }, 300 );

        // On input/change quantity event
        $(qty).on('input change', function() {
            if( $(vid).val() != '' ){
                $(button).attr('href', url + $(vid).val() + '&quantity=' + $(this).val() );
            }
        });

        // On select attribute field change event
        $('.variations_form').on('change blur', 'table.variations select', function() {
            if( $(vid).val() != '' ){
                $(button).attr('href', url + $(vid).val() + '&quantity=' + $(qty).val() );
            }
        });
    });
    </script>
    <?php
    endif;
    echo '<a href="'.$addtocart_url.'" class="'.$button_class.'">'.$button_text.'</a>';
} ```

I expect this code to work when the user does not change or update any variations on the product page. That is when the user clicks on the Buy Now button with the default variations.

您不需要在变体表单中添加按钮的所有内容，它将作为提交表单作为添加到购物车按钮然后进行重定向

这是经过测试并与我合作

 add_action( 'woocommerce_single_variation', 'second_button_single_variation', 30 );
   function second_button_single_variation() {
    global $product;

echo '<form method="post">
    <button type="submit" name="checkout_now" id="checkout_now" class="single_add_to_cart_button button alt buy_now_button" value="'.$product->get_id().'">Buy Now</button></form>';
  }

  function woo_redirect_to_checkout() {
global $woocommerce;
  if( isset($_POST['checkout_now']) ){
 wc_clear_notices();
    $checkout_url = $woocommerce->cart->get_checkout_url();
 wp_redirect($checkout_url);
  }
 }
    add_filter ('add_to_cart_redirect', 'woo_redirect_to_checkout');

 // clearing the cart if you want to go to checkout with the desired product only
  add_filter( 'woocommerce_add_to_cart_validation', 'remove_cart_item_before_add_to_cart', 20, 3 );
  function remove_cart_item_before_add_to_cart( $passed, $product_id, $quantity ) {
if( isset($_POST['checkout_now']) ){
 if( ! WC()->cart->is_empty() )
    WC()->cart->empty_cart();
}
return $passed;
  }
