WooCommerce:将产品属性添加到产品中的现有属性 [英] WooCommerce: Add a product attribute to the existing ones in a product

问题描述

我正在努力为产品添加属性.

I am struggling with adding an attribute to a product.

我有一系列要添加到产品中的关键字:

I have an array of keywords that I would like to add to a product:

$clean_keywords = array('cake','cup cakes');
$term_taxonomy_ids = wp_set_object_terms( get_the_ID(), $clean_keywords, 'pa_keywords', true );
$thedata = Array('pa_keywords' => Array(
    'name' => 'pa_keywords',
    'value' => '',
    'is_visible' => '0',
    'is_taxonomy' => '1'
));

update_post_meta( get_the_ID(),'_product_attributes',$thedata);

这很好，但是它删除了我附加到产品上的所有其他属性.

This works fine, but it deletes all my other attributes attach to the product.

我认为解决方案是获取当前属性并将其与$thedata变量合并...但是不确定如何执行此操作.

I think the solution is to get the current attributes and merge it with $thedata variable... but not sure how to do this.

有什么想法吗?

谢谢

推荐答案

您需要先获取现有产品属性，然后将新产品属性插入数组中，然后再保存.另外我在数组中添加了2个缺少的参数…

You need to get existing product attributes first and insert your new product attribute in the array before saving it. Also I have added 2 missing arguments in the array…

因此您的代码应为:

$product_id = get_the_ID();
$taxonomy = 'pa_keywords';
$clean_keywords = array('cake','cup cakes');
$term_taxonomy_ids = wp_set_object_terms( $product_id, $clean_keywords, $taxonomy, true );

// Get existing attributes
$product_attributes = get_post_meta( $product_id, '_product_attributes', true);

// get the count of existing attributes to set the "position" in the array
$count = count($product_attributes);

// Insert new attribute in existing array of attributes (if there is any)
$product_attributes[$taxonomy] = array(
    'name' => $taxonomy,
    'value' => '',
    'position' => $count, // added
    'is_visible' => '0',
    'is_variation' => '0', // added (set the right value)
    'is_taxonomy' => '1'
);

// Save the data
update_post_meta( $product_id, '_product_attributes', $product_attributes );

现在应该可以正常工作，而不会删除现有数据.

This should work now without removing existing data.
