根据类别woocommerce更改同一产品的默认变化值 [英] Change default variation value for the same product according to the category woocommerce

问题描述

我正在努力根据他的类别显示SAME产品的默认变化值. 例如，我出售的卡带有选项blue&红色的. 当用户来自类别ONE时，我希望默认值为蓝色. 如果他属于"TWO"类别，则该值将为红色.

I'm working on a way to display default variations value for the SAME product according to the category he is. For example, I sell a card with option blue & red. When the user comes by the category ONE, I want the default value is blue. If he comes by the category TWO, the value will be red.

我找到了一个钩子woocommerce_product_default_attributes，但是我不知道如何使用它.

I found a hook woocommerce_product_default_attributes, but I don't know how to use it .

注意::即使您的产品属于两类，woocommerce似乎也只能识别一种产品.

Note : It seems that woocommerce recognize only one category per product even if your product is in two category.

示例 (编辑):

我有一个产品 P .
产品 P 分为两类:Cat 1& Cat 2.
此外，产品 P 具有两个变量: Blue & Red

I have a product P.
Product P is in two categories : Cat 1 & Cat 2.
Also, product P has two variables : Blue & Red

当用户来自 Cat 1 时，我希望默认值为 Blue . 如果他来自 Cat 2 ，则值为 Red .

When the user comes by Cat 1, I want the default value is Blue. If he comes by Cat 2, the value will be Red.

@LoicTheAztech的答案代码 (如下)有效，但:

当我转到Cat 1或Cat 2时，可以看到对于Woocommerce，该产品仅位于Cat 1中，即使我们可以同时访问这两个类别.

When I go to Cat 1 or Cat 2, I can see that for Woocommerce, the product is only in Cat 1, even if we can access by both category.

因此，在一切之前，我需要解决woocommerce问题.

So before everything, I need to solve the woocommerce issue.

推荐答案

新的不同的 此处更新了答案 ，其中带有替换过滤器挂钩

New different updated answer HERE with the replacement filter hook

---

在WooCommerce 3+中，过滤器挂钩 woocommerce_product_default_attributes 位于 get_variation_default_attributes() 不推荐使用的方法中，因此它并不是正确的挂钩实现您想要的.

In WooCommerce 3+ the filter hook woocommerce_product_default_attributes is located in get_variation_default_attributes() deprecated method, so it's not really the right hook to achieve what you want.

get_variation_default_attributes()方法替换为 get_default_attributes() .

get_variation_default_attributes() method is replaced by get_default_attributes().

例如，您可以在 woocommerce_before_add_to_cart_form 操作挂钩中实现条件功能.

You can achieve your conditional function in woocommerce_before_add_to_cart_form action hook, for example.

注释:

• 产品属性分类始终以'pa_'+属性段标记
开头
• 您需要在变量"标签设置中为此变量产品设置此属性的默认值.

• Product Attribute taxonomy always begin by 'pa_' + the attribute slug
• You need to set in for variable products the default value for this attribute in the variation tab settings.

代码:

add_action( 'woocommerce_before_add_to_cart_form', function(){
    global $product;

    // We EXIT if it's not a variable product
    if( ! $product->is_type('variable') ) return;

    ## DEFINE HERE the desired product attribute taxonomy
    $pa_attribute = 'pa_color';
    $default_attribute_for_variation = $product->get_variation_default_attribute( $pa_attribute );

    // We EXIT if Product Attribute Color is not set as variation usage
    if( empty( $default_attribute_for_variation ) ) return;

    // Get the array of default attributes
    $default_attributes = $product->get_default_attributes();

    // For product category 'ONE => Attribute "blue" slug value
    if( has_term( 'clothing', 'product_cat', $product->get_id() ) )
        $default_attributes[$pa_attribute] = 'blue';

    // For product category 'TWO' => Attribute "blue" slug value
    elseif( has_term( 'TWO', 'product_cat', $product->get_id() ) )
        $default_attributes[$pa_attribute] = 'red';

    else return; // If no product categories match we exit

    // If a product category match we set the default attribute
    $product->set_default_attributes( $default_attributes );
}, 80, 0 );

代码会出现在您活动的子主题(或主题)的function.php文件中，也可能会出现在任何插件文件中.

Code goes in function.php file of your active child theme (or theme) or also in any plugin file.

此代码已经过测试并且可以正常工作.
