You can use: $available_variations = $product->get_available_variations();

您可以使用： $available_variations = $product->get_available_variations();

If this is a single style template, make sure you add global $product;near the top.

如果这是单个样式模板，请确保global $product;在顶部附近添加。

From there, you can foreach through the variations and do as you wish... since you didn't have any specific output I hope that this sets you on the right track.

从那里，您可以通过变体进行 foreach 并随心所欲……因为您没有任何特定的输出，我希望这能让您走上正确的轨道。

You can use the code below:

您可以使用以下代码：

global $woocommerce, $product, $post;
// test if product is variable
if ($product->is_type( 'variable' )) 
{
    $available_variations = $product->get_available_variations();
    foreach ($available_variations as $key => $value) 
    { 
        //get values HERE  
    }
}

The following code:

以下代码：

$variations = $product->get_available_variations();

will return all variantion of product

将返回产品的所有变体

This function is put where you show all variation:

这个函数放在你显示所有变化的地方：

\wp-content\plugins\woocommerce\templates\single-product\add-to-cart\variable.php

A common problem often starts from changing "In stock" or "Out of stock" labels for a single product. There are few solutions out there, where you need to change functions.php file and add a new filter.

一个常见的问题通常始于更改单个产品的“有货”或“缺货”标签。有几个解决方案，您需要更改functions.php 文件并添加新过滤器。

The problems get more complicated when you need to modify this for product variations.

当您需要针对产品变体进行修改时，问题会变得更加复杂。

这可能是您的解决方案：http: //bucketpress.com/changed-stock-availability-text-for-product-variations

In order to display available variations of the product you need to modify variable.php file, which can be found in /wp-content/plugins/woocommerce/templates/single-product/add-to-cart/

为了显示产品的可用变体，您需要修改 variable.php 文件，该文件可以在 /wp-content/plugins/woocommerce/templates/single-product/add-to-cart/ 中找到

Find this:

找到这个：

<form class="variations_form cart" method="post" enctype='multipart/form-data' data-product_id="<?php echo absint( $product->id ); ?>" data-product_variations="<?php echo htmlspecialchars( json_encode( $available_variations ) ) ?>">

and before tag paste this code:

并在标记之前粘贴此代码：

foreach( $available_variations as $i => $variation ) {
//check if variation has stock or not 
if ( $variation['is_in_stock'] ) {
    // Get max qty that user can purchase
    $max_qty = $variation['max_qty'];

    // Prepare availability html for stock available instance
    $availability_html = '<p class="stock in-stock">' . $max_qty . ' units available for your purchase.' . '</p>';
} else {
    // Prepare availability html for out of stock instance
    $availability_html = '<p class="stock out-of-stock">Oops, we have no stock left.</p>';
}
$available_variations[$i]['availability_html'] = $availability_html; }

Don't forget to move php end tag "?>" from this line

不要忘记从这一行移动php结束标记“？>”

do_action( 'woocommerce_before_add_to_cart_form' ); ?>

after your new code.

在您的新代码之后。

So the complete variable.php file should like something like this (WooCommerce 3.2.4):

所以完整的 variable.php 文件应该像这样（WooCommerce 3.2.4）：

<?php
/**
 * Variable product add to cart
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/single-product/add-to-cart/variable.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you
 * (the theme developer) will need to copy the new files to your theme to
 * maintain compatibility. We try to do this as little as possible, but it does
 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.
 *
 * @see     https://docs.woocommerce.com/document/template-structure/
 * @author  WooThemes
 * @package WooCommerce/Templates
 * @version 3.0.0

global $product;

$attribute_keys = array_keys( $attributes );

do_action( 'woocommerce_before_add_to_cart_form' ); 

// Your New Code goes here:
foreach( $available_variations as $i => $variation ) {
    // check if variation has stock or not 
    if ( $variation['is_in_stock'] ) {
        // Get max qty that user can purchase
        $max_qty = $variation['max_qty'];

        // Prepare availability html for stock available instance
        $availability_html = '<p class="stock in-stock">Available: ' . $max_qty . '</p>';
    } else {
        // Prepare availability html for out of stock instance
        $availability_html = '<p class="stock out-of-stock">Out of stock!</p>';
    }
    $available_variations[$i]['availability_html'] = $availability_html;

Try this,

尝试这个，

<?php
