如果产品出现在 WooCommerce 完成的订单中，则为某些产品 ID 自定义添加到购物车按钮

Question

我之前的问题已经得到解答，我想进一步扩展

如何为特定产品添加自定义 url（我认为产品是数字或物理类型很常见）

以下是我尝试为特定产品编写的示例代码的一部分：

// for the product ID 45 (for example) 
if( $product->id == 45 ){ 
    $add_to_cart_url = site_url('/custom-link/product-45/');
    $button_text = __('View order now', 'woocommerce');
}

我不知道如何 add/write 这个。有什么建议吗？

Answer 1

其实你的问题很简单，就是加个if/else条件。您可以使用 in_array() 为 1 个或多个 productID 执行 if 条件。

注意： 因为 WooCommerce 3 使用 $product->get_id() 而不是 $product->id

对于 WooCommerce 商店和档案页面：

替换

// When NOT empty
if ( ! empty( $order_id ) ) {
    // Setting
    $button_text_view_order = __( 'View order now', 'woocommerce' );
    
    // Get view order url
    $view_order_url = wc_get_endpoint_url( 'view-order', $order_id, wc_get_page_permalink( 'myaccount' ) );
    
    // New link + text
    $sprintf = sprintf(
        '<a href="%s" class="%s">%s</a>',
        esc_url( $view_order_url ),
        esc_attr( isset( $args['class'] ) ? $args['class'] : 'button' ),
        esc_html( $button_text_view_order )
    );
}

有

// When NOT empty
if ( ! empty( $order_id ) ) {
    // Products IDs, several can be added, separated by a comma
    $product_ids = array( 45 );
    
    // Checks if a value exists in an array
    if ( in_array( $product->get_id(), $product_ids ) ) {
        // Button text
        $button_text = __( 'For certain productIDs', 'woocommerce' );
        
        // Button url
        $button_url = site_url( '/custom-link/' );          
    } else {    
        // Button text - view order
        $button_text = __( 'View order now', 'woocommerce' );
        
        // Button url - get view order url
        $button_url = wc_get_endpoint_url( 'view-order', $order_id, wc_get_page_permalink( 'myaccount' ) );
    }
    
    // New link + text
    $sprintf = sprintf(
        '<a href="%s" class="%s">%s</a>',
        esc_url( $button_url ),
        esc_attr( isset( $args['class'] ) ? $args['class'] : 'button' ),
        esc_html( $button_text )
    );
}

单个产品页面：

替换

// When NOT empty
if ( ! empty( $order_id ) ) {
    // Remove default add to cart button and add a custom one
    remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_add_to_cart', 30 );
    
    // Add action, priority 30 and pass data to add action function
    add_action( 'woocommerce_single_product_summary', function() use ( $order_id ) {
        // Setting
        $button_text_view_order = __( 'View order now', 'woocommerce' );
        
        // Get view order url
        $view_order_url = wc_get_endpoint_url( 'view-order', $order_id, wc_get_page_permalink( 'myaccount' ) );
        
        echo '<a href="' . $view_order_url . '" class="button">' . $button_text_view_order . '</a>';
    }, 30, 0 );
}

有

// When NOT empty
if ( ! empty( $order_id ) ) {
    // Remove default add to cart button and add a custom one
    remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_add_to_cart', 30 );
    
    // Products IDs, several can be added, separated by a comma
    $product_ids = array( 30 );
    
    // Checks if a value exists in an array
    if ( in_array( $product->get_id(), $product_ids ) ) {
        // Button text
        $button_text = __( 'For certain productIDs', 'woocommerce' );
        
        // Button url
        $button_url = site_url( '/custom-link/' );          
    } else {    
        // Button text - view order
        $button_text = __( 'View order now', 'woocommerce' );
        
        // Button url - get view order url
        $button_url = wc_get_endpoint_url( 'view-order', $order_id, wc_get_page_permalink( 'myaccount' ) );
    }
    
    // Add action, priority 30 and pass data to add action function
    add_action( 'woocommerce_single_product_summary', function() use ( $button_text, $button_url ) {            
        // New custom button, adjust classes if necessary (theme related)
        echo '<a href="' . $button_url . '" class="single_add_to_cart_button button alt">' . $button_text . '</a>';
    }, 30, 0 );
}

完整的最终结果：

    global $wpdb;
