WooCommerce-获取自定义产品属性 [英] WooCommerce - Get custom product attribute

问题描述

我正在尝试在woocommerce中获取特定的自定义属性. 我已经在该站点上阅读了大量的线程，其中提供了大约3-5种方法. 经过全部尝试之后，唯一对我有用的方法是遍历所有属性-所有其他属性均无效. 我有一个名为"pdfs"的自定义属性

以下尝试无效:(链接)

 $global product;
 $myPdf = array_shift( wc_get_product_terms( $product->id, 'pdfs', array( 'fields' => 'names' ) ) );

 $myPdf = $product->get_attribute( 'pdfs' );

 $myPdf = get_post_meta($product->id, 'pdfs', true);

这是唯一起作用的:(

我宁愿能够使用第一个选项 任何帮助将不胜感激.
谢谢

解决方案

更新:增加了对Woocommerce 3+的兼容性

由于属性始终在数据库中以 pa_ 开头，因此要使用 wc_get_product_terms() 功能获取它们，您将需要使用 pa_pdfs ，而不是 pdfs ，方法是:

global $product;

$product_id = method_exists( $product, 'get_id' ) ? $product->get_id() : $product->id; // Added WC 3+ support

$myPdf = array_shift( wc_get_product_terms( $product_id, 'pa_pdfs', array( 'fields' => 'names' ) ) );

参考:如何从WooCommerce获取产品自定义属性

I am trying to get a specific custom attribute in woocommerce. I've read tons of threads on this site which offer about 3-5 methods how to do it. After trying all, the only method that worked for me is to loop through all attributes - all others did not work. I have a custom attribute named 'pdfs'

The following tries did not work: (link)

 $global product;
 $myPdf = array_shift( wc_get_product_terms( $product->id, 'pdfs', array( 'fields' => 'names' ) ) );

 $myPdf = $product->get_attribute( 'pdfs' );

 $myPdf = get_post_meta($product->id, 'pdfs', true);

This is the only one that did work: (link)

 $attributes = $product->get_attributes();
 foreach ( $attributes as $attribute ) {
    if (attribute_label( $attribute[ 'name' ] ) == "pdfs" ) {
        echo array_shift( wc_get_product_terms( $product->id,  $attribute[ 'name' ] ) );
    }
}

I would much rather be able to use one of the first options Any help would be appreciated.
Thanks

解决方案

Update: Added compatibility for Woocommerce 3+

As attributes are always prepend with pa_ in DB, for getting them with wc_get_product_terms() function, you will need to use pa_pdfs instead of pdfs, this way:

global $product;

$product_id = method_exists( $product, 'get_id' ) ? $product->get_id() : $product->id; // Added WC 3+ support

$myPdf = array_shift( wc_get_product_terms( $product_id, 'pa_pdfs', array( 'fields' => 'names' ) ) );
