自动删除购物车中的缺货商品，然后通知帐户用户 - Woocommerce

Question

我希望允许客户将商品添加到他们的 Woocommerce 购物车中，并在他们想要的时候将其保留在那里，以便他们可以在闲暇时添加到购物车中。任何缺货的行都需要自动从购物车中删除，并显示一条消息以表明已发生这种情况。诸如“所有缺货商品已从帐户中删除，因为它们不再可用”之类的内容。

到目前为止，我已经尝试过了

public function is_in_stock() {
return apply_filters( 'woocommerce_product_is_in_stock', 'instock' === $this->get_stock_status(), $this );
}
function notes_in_cart() {
 global $woocommerce;

if ( ! $_POST || ( is_admin() && ! is_ajax() ) ) {
    return;
}

if ( isset( $_POST['post_data'] ) ) {
    parse_str( $_POST['post_data'], $post_data );
} else {
    $post_data = $_POST; // fallback for final checkout (non-ajax)
}

if ( WC()->cart->needs_shipping() ){

    // set $out_of_stock_exists to false by default
    $out_of_stock_exists = false;
    foreach ( $woocommerce->cart->get_cart() as $cart_item_key => $values ) {
        if($values['data']->backorders_allowed()){ //check if backorders are allowed on this product
            // get the stock quantity - returns the available amount number
            $stock_info = $values['data']->get_stock_quantity();

            if($stock_info < $values['quantity']){ 
    set $out_of_stock_exists to true and stop foreach execution
                $out_of_stock_exists = true;
                break;
            }
        }

    }

    //if cart has items out of stock
    if ($out_of_stock_exists) {
        ?>
        <tr class="ceckoutStockMeta">
            <th>Item Shipments</th>
            <td>
                <p style="color: red;">*All out of stock items have been removed from your cart as they are no longer available.</p><br>
                <form>

                    <input type="radio" name="stockOp" id="stockOption1" value="ship" />
                    <label for="stockOption1">Ship what is available now</label><br>

                    <input type="radio" name="stockOp" id="stockOption2" value="hold" />
                    <label for="stockOption2">Wait and ship together</label>
                </form>
            </td>
        </tr>

        <?php

    }
}
add_action( 'woocommerce_cart_totals_after_order_total', 'notes_in_cart' );
add_action( 'woocommerce_review_order_after_order_total', 'notes_in_cart' );

我不确定是否所有这些都是必要的，考虑到无论如何都需要禁止延期交货。

谁能告诉我这是否正确？

至于从帐户的购物车中自动删除缺货行，我猜这将在 Woocommerce 中“开箱即用”发生。有人可以确认这一点或提供一种方法吗？

谢谢你， 布莱恩

我已经弄清楚我哪里错了，我完全走错了路。我在下面发布正确的代码，以防其他人将来需要此功能。它两者兼而有之，在产品缺货时更新购物车并同时留下新消息。

/**
 * This code will automatically remove any out of stock items from a shopping cart.
 * This would be in cases when users add products to their cart and come back to it later.
*
*/
function orb_check_for_out_of_stock_products() {
if ( WC()->cart->is_empty() ) {
    return;
}

$removed_products = [];

foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
    $product_obj = $cart_item['data'];

    if ( ! $product_obj->is_in_stock() ) {
        WC()->cart->remove_cart_item( $cart_item_key );
        $removed_products[] = $product_obj;
    }
}

if (!empty($removed_products)) {
    wc_clear_notices(); // remove any WC notice about sorry about out of stock products to be removed from cart.

    foreach ( $removed_products as $idx => $product_obj ) {
        $product_name = $product_obj->get_title();
        $msg = sprintf( __( "The product '%s' was removed from your cart because it is now out of stock. Sorry for any inconvenience caused.", 'woocommerce' ), $product_name);

        wc_add_notice( $msg, 'error' );
    }
}

}
add_action('woocommerce_before_cart', 'orb_check_for_out_of_stock_products');

感谢那些提供帮助的人，非常感谢http://orbisius.com/ 的 Svetoslav Marinov 直接与我联系并提供他的意见。是他带领我走向了正确的方向。
