在Woocommerce中以编程方式创建新产品属性 [英] Create new product attribute programmatically in Woocommerce

问题描述

如何通过插件为WooCommerce创建属性? 我只找到:

How can I create attributes for WooCommerce from a plugin? I find only :

wp_set_object_terms( $object_id, $terms, $taxonomy, $append);

来自此堆栈问题

但是这种方法需要某些产品的ID.我需要生成一些未附加到任何产品的属性.

But this approach required id of some product. I need to generate some attributes not attached to any products.

推荐答案

要创建术语，可以使用 wp_insert_term()

To create a term you can use wp_insert_term()

像这样:

wp_insert_term( 'red', 'pa_colors' );

其中，colors是属性的名称.属性的分类名称始终以pa_开头.

where colors is the name of your attribute. The taxonomy name of an attribute is always prepended by pa_.

编辑属性仅仅是自定义分类法.或者，您可以说它们是由用户在后端手动创建的动态分类法.尽管如此，自定义分类规则仍然适用.

Edit Attributes are merely custom taxonomies. Or you could say they are dynamic taxonomies that are manually created by the user in the back-end. Still, all the same, custom taxonomy rules apply.

您可以看到源代码此处的代码，它遍历属性并在每个属性上运行 register_taxonomy() .因此，要创建一个新的属性(请记住，这只是一个分类法)，则需要运行register_taxonomy()并将简单的pa_前置在分类法名称的开头.

You can see the source code here which loops through the attributes and runs register_taxonomy() on each. So to create a new attribute (remember it is just a taxonomy) then you need to run register_taxonomy() and simple prepend pa_ to the start of the taxonomy name.

从核心中模拟分类法args的某些值将为颜色"属性提供类似的信息.

Mimicking some of the values of the taxonomy args from core would get you something like this for a 'Colors' attribute.

add_action( 'woocommerce_after_register_taxonomy', 'so_29549525_register_attribute' );

function so_29549525_register_attribute(){

    $permalinks = get_option( 'woocommerce_permalinks' );

    $taxonomy_data = array(
                        'hierarchical'          => true,
                        'update_count_callback' => '_update_post_term_count',
                        'labels'                => array(
                                'name'              => 'Colors',
                                'singular_name'     => 'Color',
                                'search_items'      => sprintf( __( 'Search %s', 'woocommerce' ), $label ),
                                'all_items'         => sprintf( __( 'All %s', 'woocommerce' ), $label ),
                                'parent_item'       => sprintf( __( 'Parent %s', 'woocommerce' ), $label ),
                                'parent_item_colon' => sprintf( __( 'Parent %s:', 'woocommerce' ), $label ),

                                'update_item'       => sprintf( __( 'Update %s', 'woocommerce' ), $label ),
                                'add_new_item'      => sprintf( __( 'Add New %s', 'woocommerce' ), $label ),
                                'new_item_name'     => sprintf( __( 'New %s', 'woocommerce' ), $label )
                            ),
                        'show_ui'           => false,
                        'query_var'         => true,
                        'rewrite'           => array(
                            'slug'         => empty( $permalinks['attribute_base'] ) ? '' : trailingslashit( $permalinks['attribute_base'] ) . sanitize_title( 'colors' ),
                            'with_front'   => false,
                            'hierarchical' => true
                        ),
                        'sort'              => false,
                        'public'            => true,
                        'show_in_nav_menus' => false,
                        'capabilities'      => array(
                            'manage_terms' => 'manage_product_terms',
                            'edit_terms'   => 'edit_product_terms',
                            'delete_terms' => 'delete_product_terms',
                            'assign_terms' => 'assign_product_terms',
                        )
                    );

  register_taxonomy( 'pa_colors', array('product'), $taxonomy_data );

}
