How get variation's stock quantity woocommerce
提问by SeiyaJapon
I'm developing a theme for wordpress and woocommerce.
我正在为 wordpress 和 woocommerce 开发一个主题。
I need show variation's stock.
我需要显示变体的库存。
<p class="stock-m13"><?php echo $product->get_stock_quantity(); ?></p>
(here: How to get the stock quantity of an article from woocommerce?) but this code only show me the global stock quantity, not each variation quantity.
（此处：如何从 woocommerce 获取文章的库存数量？）但此代码仅显示全局库存数量，而不是每个变化数量。
I need another function to get variation quantity? Or it is possible that my code is not completed (I think it because I have used Twenty Fifteen theme and variation quantity is showed)?
我需要另一个函数来获取变化量吗？或者有可能我的代码没有完成（我认为是因为我使用了二十五个主题并且显示了变化数量）？
I try to get max quantity with this:
我尝试通过以下方式获得最大数量：
<?php
foreach ($product->get_available_variations() as $key) {
echo $key['max_qty'] .'<br/>';
}
?>
And I get it, but I don't know if this is useful when the stock goes down.
我明白了，但我不知道这在股票下跌时是否有用。

Ok, with this I can take the quantity. But is not useful.
好的，有了这个，我可以接受数量了。但是没有用。
With this I can prepare a code that make differents sentences, one for each product, and show it when a variation would be selected using jquery.
有了这个，我可以准备一个代码来制作不同的句子，每个产品一个，并在使用 jquery 选择变体时显示它。
But this is not good idea. Is not elegant. I though existed something like
但这不是个好主意。不优雅。我虽然存在类似的东西
$product->get_variation_price()
This code return the variation price when is selected. But
此代码在选择时返回变化价格。但
$product->get_stock_quantity();
not change when variation is selected because show me the global stock.
选择变体时不会改变，因为向我展示全球库存。
Can somebody give me an elegant solution? Or not exists?
有人可以给我一个优雅的解决方案吗？还是不存在？
UPDATE
更新
Finally I used
最后我用
$product->get_available_variations()
To get the data.
来获取数据。
With this I've generated html code, hidden with css, and I show it when I click on variation's color.
有了这个，我生成了 html 代码，用 css 隐藏，当我点击变体的颜色时我会显示它。

Given a variable product with multiple variations in order to get each variation stock quantity:
给定具有多个变体的可变产品，以获得每个变体的库存数量：
function get_stock_variations_from_product(){
global $product;
$variations = $product->get_available_variations();
foreach($variations as $variation){
$variation_id = $variation['variation_id'];
$variation_obj = new WC_Product_variation($variation_id);
$stock = $variation_obj->get_stock_quantity();
}
}
This is the cleanest way I figured out for WC 2.5, I think there might be better ways in terms of performance but not as clean.
这是我为 WC 2.5 找到的最干净的方法，我认为在性能方面可能有更好的方法，但没有那么干净。

The below code will print all attributes with 'is_in_stock' variable.
下面的代码将使用“ is_in_stock”变量打印所有属性。
<?php
global $product;
$product_variations = $product->get_available_variations();
foreach ($product_variations as $variation) {
$var_data = $variation['attributes'];
$var_data['in_stock'] = $variation['is_in_stock'];
}
//List all attributes with stock available or not array..
echo '<pre>';
print_r($var_data);
echo '</pre>';
die;
?>
回答by Tuesdave
Yes, your way is the correct way to grab a variation's stock.
是的，您的方法是获取变体库存的正确方法。
As long as you are getting the variations fresh from the database every time you need to use its stock quantity then you should be okay with using this method.
只要您每次需要使用其库存数量时都从数据库中获取最新的变化，那么您应该可以使用这种方法。

I'm not sure I understand what you're trying to do. You should just be able to grab both variation stock and send them over to jquery to play with.
我不确定我是否理解你想要做什么。您应该能够获取两种变体库存并将它们发送到 jquery 来使用。
$product_variable = new WC_Product_Variable($product->id);
$product_variations = $product_variable->get_available_variations();
foreach ($product_variations as $variation) {
$stock[$variation['attribute_pa_variation-name']] = $variation['max_qty'];
}
Here I'm assigning stock level to an associative array with attribute_pa_"your-attribute-name" as the key
在这里，我将库存水平分配给一个以 attribute_pa_"your-attribute-name" 作为键的关联数组
Now I can send my array over to jQuery.
现在我可以将我的数组发送到 jQuery。
Please clarify if I'm mis-understanding the question.
请澄清我是否误解了这个问题。
