向 WooCommerce 添加产品的问题-解网

问：

我正在尝试向 WooCommerce 添加一些产品，我为此开设了一门课。这是我的公共插入函数：

public function insert()
{
    $this->_insert_product();
    $this->_update_variations();
    $this->_update_featured_image();
    $this->_update_attributes();
    $this->_update_categories();
    $this->_update_tags();
    $this->_update_custom_fields();
    $this->_update_product_price();
    $this->_update_sku();
    $this->_update_stock();
    return true;
}

这将插入产品、插入变体和其他一些东西。问题出在库存上！当我添加我的产品时，一切都很好，但对于可变产品，当我使用管理面板保存产品或从该产品购买一件商品时，该产品将缺货，我肯定不希望这样。变体仍然有库存，用户可以毫无问题地购买产品，但产品缺货徽章显示在产品上，并且管理面板中的状态为缺货。我可以使用一些帮助吗？

private function _update_stock()
{
    // $this->id is product id
    // This will generate $this->stock variable (0 or 1 or 2 and etc)
    $this->_generate_stock();
    // If product type is simple just update product stock and stock status
    // This is working just fine
    if ($this->type == 'simple') {
        update_post_meta($this->id, '_manage_stock', 'yes');
        update_post_meta($this->id, '_stock', $this->stock);
        if ($this->stock > 0) update_post_meta($this->id, '_stock_status', 'instock');
        else update_post_meta($this->id, '_stock_status', 'outofstock');
        update_post_meta($this->id, '_backorders', 'no');
    }
    // Else if product type is variable (PROBLEM IS HERE)
    else {
        // Variable to store if any of variations has stock
        $has_stock = false;
        // $this->variations is an array of variations ids
        for ($i = 0; $i < count($this->variations); $i++) {
            // Enable stock management for variation
            update_post_meta($this->variations[$i], '_manage_stock', 'yes');
            // Update stock ($this->stock is an array of stocks for each variation)
            update_post_meta($this->variations[$i], '_stock', $this->stock[$i]);
            // Disable backorders
            update_post_meta($this->variations[$i], '_backorders', 'no');
            // If variation has stock update stock status to in stock
            if ($this->stock[$i] > 0) {
                update_post_meta($this->variations[$i], '_stock_status', 'instock');
                $has_stock = true;
            }
            // Else update stock status to out of stock
            else update_post_meta($this->variations[$i], '_stock_status', 'outofstock');
        }
        // Sync variation
        WC_Product_Variable::sync($this->id);
        // Update stock status of main product
        if ($has_stock) update_post_meta($this->id, '_stock_status', 'instock');
        else update_post_meta($this->id, '_stock_status', 'outofstock');
    }

您应该调用 WC_Product_Variable：：sync（$this->id）;在更新所有变体之后，而不是在循环中。此方法将变量乘积与其变体同步，并且应在所有变体更新后调用。

@user580950是的，我试过了，但问题仍然在这里。

从 WooCommerce 3 开始，您应该使用可用的 CRUD 方法而不是 WordPress 函数，因为 WooCommerce 正在逐步迁移到自定义数据库表。提供的代码是不可测试的，所以没有人能真正猜测并找出问题所在，给出一个有用的工作答案......请参阅如何创建最小的可重现示例

正如评论中所讨论的，我删除了可变产品库存状态的手动更新，并允许 WooCommerce 根据其变体库存状态自动同步可变产品状态。我希望这有助于解决问题

private function _update_stock()
{
    $this->_generate_stock();
    if ($this->type == 'simple') {
        update_post_meta($this->id, '_manage_stock', 'yes');
        update_post_meta($this->id, '_stock', $this->stock);
        update_post_meta($this->id, '_stock_status', $this->stock > 0 ? 'instock' : 'outofstock');
        update_post_meta($this->id, '_backorders', 'no');
    } else {
        foreach ($this->variations as $i => $variation_id) {
            update_post_meta($variation_id, '_manage_stock', 'yes');
            update_post_meta($variation_id, '_stock', $this->stock[$i]);
            update_post_meta($variation_id, '_backorders', 'no');
            update_post_meta($variation_id, '_stock_status', $this->stock[$i] > 0 ? 'instock' : 'outofstock');
        }
        WC_Product_Variable::sync($this->id);
        WC_Product_Variable::sync_stock_status($this->id);

    }
}

我试过这个，但正如我所说，现在的产品从一开始就缺货，但变化很好，可以购买。

答案已更新，以在更新所有变体后同步父产品的库存状态：

还是同样的问题，我添加了其他可能是问题的功能

上一个：向传递到购物车的 WooCommerce 产品变体添加费用

下一个：将 WooCommerce 的“重量”属性文本标签更改为“发货重量”
