woocommerce_thankyou挂钩函数的致命错误问题

问题描述

我需要根据WooCommerce感谢页面上的付款方式打印不同的消息。

我正在使用下面的代码，但是它使我的网站崩溃并显示以下错误：

致命错误：未捕获错误：在int上调用成员函数get_payment_method（）...

add_action( 'woocommerce_thankyou','bbloomer_add_content_thankyou' );
 
function bbloomer_add_content_thankyou($order) {
         if( 'bacs' == $order->get_payment_method() ) {

echo '<h2 class="h2thanks">Get 20% off</h2><p class="pthanks">Thank you for making this purchase! Come back and use the code "<strong>Back4More</strong>" to receive a 20% discount on your next purchase!</p>';
         }
    else{
        echo '<h2 class="h2thanks">Get 100% off</h2><p class="pthanks">Thank you for making this purchase! Come back and use the code "<strong>Back4More</strong>" to receive a 20% discount on your next purchase!</p>';

    }
    
}

有人可以告诉我哪里出了问题吗？

解决方法

通过woocommerce_thankyou钩子，您可以访问$order_id，而不是$order对象本身，因此会出错。

要获取$order对象，可以使用wc_get_order( $order_id ); 通过$order_id获得$order对象。

所以您得到：

function bbloomer_add_content_thankyou( $order_id ) {    
    // Get $order object
    $order = wc_get_order( $order_id );
    
    // Is a WC_Order
    if ( is_a( $order,'WC_Order' ) ) {
        // Payment method = bacs
        if( $order->get_payment_method() == 'bacs' ) {
            echo '<h2 class="h2thanks">Get 20% off</h2><p class="pthanks">Thank you for making this purchase! Come back and use the code "<strong>Back4More</strong>" to receive a 20% discount on your next purchase!</p>';
        } else {
            echo '<h2 class="h2thanks">Get 100% off</h2><p class="pthanks">Thank you for making this purchase! Come back and use the code "<strong>Back4More</strong>" to receive a 20% discount on your next purchase!</p>';
        }
    }
}
add_action( 'woocommerce_thankyou','bbloomer_add_content_thankyou',10,1 );
