如果父类别在产品编辑页面中的 ID 为 33,您知道如何使用所有货物的自定义元值和类别名称填充如下示例的选择选项下拉列表吗?我只知道错过了自定义元值部分 - 似乎类别名称工作正常。
<?PHP // Populate Dropdown with Brand from Parent Category with ID 33 ?>
<?PHP
$args = array(
'orderby' => 'name','order' => 'ASC','hide_empty' => 0,'taxonomy' => 'product_cat','parent' => '33'
);
$categories = get_categories($args);
foreach($categories as $cat) {
?>
<option value="<?PHP echo $cat->name; ?>" ><?PHP echo $cat->CUSTOM-Meta???; ?></option>
<?PHP
}
?>
解决方法
要获取给定类别的自定义元值,您可以使用 get_term_meta 函数。
<option value="<?php echo $cat->name; ?>" >
<?php echo get_term_meta($cat->term_id,'custom_term_meta',true); ?>
</option>
