Question

如果购物车中有缺货商品，我需要在结帐订单中显示一个部分（b / c我们的产品可以延期交货）。以下是显示部分...

的代码

的functions.php：

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() ){
        //if cart has items out of stock
        //if (cart has out of stock product) {
        ?>
            <tr class="ceckoutStockMeta">
                <th>Item Shipments</th>

                <td>
                    <p style="color: red;">*You have one or more items in your cart that are currently out of stock. Please select a custom shipping option for your order.</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' );

现在该部分一直显示。我知道我可能需要调用购物车物品并与foreach一起循环以确定是否缺货，但不确定如何。

您可以这样做来检查＆＃34;库存数量＆＃34;和＃34;允许延期交货？＆＃34;产品属性：

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']){ //thanks to LoicTheAztec for pointing it out in his answer
                    // 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;">*You have one or more items in your cart that are currently out of stock. Please select a custom shipping option for your order.</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' );

也可以使用get_stock_status（）或is_in_stock（）方法来完成，它返回＆＃34; Stock status＆＃34;的值。 - ＆＃39; instock＆＃39;或者＆＃39; outofstock＆＃39; - 但不允许使用延期交货结账：https://github.com/woocommerce/woocommerce/issues/11187或https://github.com/woocommerce/woocommerce/issues/10834

编辑：有关为什么is_in_stock（）不起作用的更多详细信息： is_in_stock（）方法就是这个：

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

这意味着它会检查＆＃34;股票状态＆＃34;如果＆＃34;库存＆＃34;它返回true如果＆＃34;缺货＆＃34;则为假。

现在，如果你在这里阅读：https://conschneider.de/manage-stock-backorders-woocommerce/

你会发现：

只要库存状态为“in”，就可以进行延期交货股票”。将产品设置为缺货将再次阻止购买并显示“缺货”。

Answer 2

已更新：由于所有产品均可在延期交货中使用，唯一有效的方法是检查 foreach 循环，如果库存数量每个购物车项目数量“足够”......

如果产品的库存数量小于购物车数量（WC显示“延期交货”），则会显示您的“货件单”

以下是代码：

function notes_in_cart() {

    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)
    }

    // Loop that check if cart items have enough stock quantity 
    $is_available_on_backorder = false;
    foreach ( WC()->cart->get_cart() as $item_values ) {

        $stock_qty = $item_values['data']->get_stock_quantity(); // Product stock
        $item_qty = $item_values['quantity']; // Cart Item quantity

        // Testing if the product has enough stock
        if( $stock_qty < $item_qty ){ 
             $is_available_on_backorder = true; // The condition is met
             break; // we stop the loop
        }
    }

    if ( WC()->cart->needs_shipping() && $is_available_on_backorder ){
        ?>
            <tr class="ceckoutStockMeta">
                <th>Item Shipments</th>
                <td>
                    <p style="color: red;">*You have one or more items in your cart that are currently out of stock. Please select a custom shipping option for your order.</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' );

代码放在活动子主题（或主题）的function.php文件中，或者放在任何插件文件中。

此代码经过测试并有效。
