以下代码在WooCommerce产品类别部分添加了一个额外的字段，除此之外我还需要一些额外的字段。我需要在下面的代码中更改以添加更多类似的字段。
提前感谢您的帮助。
// Add term page
add_action( 'product_cat_add_form_fields', 'wpm_taxonomy_add_new_meta_field', 10, 2 );

// retrieve the existing value(s) for this meta field. This returns an array

要添加更多字段，您必须在函数中添加更多表单字段，然后将其保存在保存功能中。在我的下面的函数中创建了一个额外的字段product_cat_thumbnailbig_id，用于在类别部分创建自定义图像上传选项。您的 detais 部分也在这里工作。按照我的代码创建所需的字段。

add_action( 'product_cat_add_form_fields', 'wpm_taxonomy_add_new_meta_field', 10, 2 );

您可以在单个函数中添加多个字段，如下所示。
这是代码
//Product Cat creation page
function wpm_taxonomy_add_new_meta_field() {
?>
<div class="form-field">
<label for="term_meta[wh_meta_title]"><?php _e('Meta Title', 'text_domain'); ?></label>
<input type="text" name="term_meta[wh_meta_title]" id="term_meta[wh_meta_title]">
<p class="description"><?php _e('Enter a meta title, <= 60 character', 'text_domain'); ?></p>
</div>
<div class="form-field">
<label for="term_meta[wh_meta_desc]"><?php _e('Meta Description', 'text_domain'); ?></label>
<textarea name="term_meta[wh_meta_desc]" id="term_meta[wh_meta_desc]"></textarea>
<p class="description"><?php _e('Enter a meta description, <= 160 character', 'text_domain'); ?></p>
</div>
<?php
}
add_action('product_cat_add_form_fields', 'wpm_taxonomy_add_new_meta_field', 10, 2);
