bru*_*496 3 php wordpress woocommerce
我在我的网站上使用 woocommerce,但由于我只有一个主要产品和两个配件(相关产品),我不需要经典的商店页面,也不需要每个产品的单一产品页面。我的主要产品有颜色变化。
我想要一个添加到购物车的按钮,在我的常规帖子页面之一中带有颜色变化下拉列表和数量字段。就像在单个产品页面上一样,但嵌入在我自己的页面中,并且没有我不需要的单个产品页面的部分(描述,...)。
我最终决定使用我创建的两个自定义短代码来实现这一点:[my_vc_product_price id="xxx"]和[my_vc_add2cart_variable_product id="xxx"]. 所以我可以把它们放在我想要的地方。
但我的问题是下拉菜单+变体可用性+添加到购物车按钮的行为与单个产品页面中该元素的行为不同:-当我选择时,变体的可用性不显示下拉菜单中的颜色;- 当下拉菜单中没有选择颜色时,添加到购物车按钮不会被禁用(它应该被禁用并只有在选择了一种颜色时才处于活动状态)。
显示价格很容易,使用一些在互联网上找到的代码:
/**
* Add shortcode to allow to display product price in a page
*/
function my_vc_display_product_price( $args ) {
$product_id = $args['id'];
$product = wc_get_product( $product_id );
echo '<p class="price">' . $product->get_price_html() . '</p>';
}
add_shortcode( 'my_vc_product_price', 'my_vc_display_product_price');

为了获得相同的图形结果,我只需要在行中添加一些 CSS 类:“woocommerce”和“product”。
显示下拉菜单 + 数量和添加到购物车按钮的代码与 plugins/woocommerce/templates/single-product/add-to-cart/ 中的 variable.php 文件几乎相同。唯一真正改变的是您需要获取产品的“变体属性”,而不是属性。
$attributes = $product->get_variation_attributes();
$attribute_keys = array_keys( $attributes );

所以完整的函数代码是:
/**
* Add shortcode to allow to display an add to cart button with dropdown menu for variation attributes
*/
function my_vc_add_to_cart_button_variable_product( $args ) {
global $product;
$product_id = $args['id'];
$product = wc_get_product( $product_id );
if( $product->is_type( 'variable' )) {
$attributes = $product->get_variation_attributes();
$attribute_keys = array_keys( $attributes );
$available_variations = array( $product->get_available_variations() );
do_action( 'woocommerce_before_add_to_cart_form' ); ?>

知道出了什么问题吗?我不明白,如果代码相同,为什么不执行相同的代码。由于此代码在 woocommerce 页面之外,是否缺少某些内容?
尝试使用以下代码
function add_to_cart_form_shortcode( $atts ) {
if ( empty( $atts ) ) {
return '';
}
if ( ! isset( $atts['id'] ) && ! isset( $atts['sku'] ) ) {
return '';
}
$args = array(
'posts_per_page' => 1,
'post_type' => 'product',
'post_status' => 'publish',
'ignore_sticky_posts' => 1,
'no_found_rows' => 1,
);
if ( isset( $atts['sku'] ) ) {
$args['meta_query'][] = array(
'key' => '_sku',
'value' => sanitize_text_field( $atts['sku'] ),
'compare' => '=',
);
$args['post_type'] = array( 'product', 'product_variation' );
}
if ( isset( $atts['id'] ) ) {
$args['p'] = absint( $atts['id'] );
}
$single_product = new WP_Query( $args );
$preselected_id = '0';
if ( isset( $atts['sku'] ) && $single_product->have_posts() && 'product_variation' === $single_product->post->post_type ) {
$variation = new WC_Product_Variation( $single_product->post->ID );
