我没有使用自定义字段,而是通过在 functions.php 中添加这些代码来添加自定义分类法。现在我必须弄清楚如何在前端表单中显示它。
function add_custom_taxonomies() {
// Add new "Locations" taxonomy to Posts
register_taxonomy('location', 'post', array(
// Hierarchical taxonomy (like categories)
'hierarchical' => true,
// This array of options controls the labels displayed in the WordPress Admin UI
'labels' => array(
'name' => _x( 'Locations', 'taxonomy general name' ),
'singular_name' => _x( 'Location', 'taxonomy singular name' ),
'search_items' => __( 'Search Locations' ),
'all_items' => __( 'All Locations' ),
'parent_item' => __( 'Parent Location' ),
'parent_item_colon' => __( 'Parent Location:' ),
'edit_item' => __( 'Edit Location' ),
'update_item' => __( 'Update Location' ),
'add_new_item' => __( 'Add New Location' ),
'new_item_name' => __( 'New Location Name' ),
'menu_name' => __( 'Locations' ),
),
// Control the slugs used for this taxonomy
'rewrite' => array(
'slug' => 'locations', // This controls the base slug that will display before each term
'with_front' => false, // Don't display the category base before "/locations/"
'hierarchical' => true // This will allow URL's like "/locations/boston/cambridge/"
),
));
}
add_action( 'init', 'add_custom_taxonomies', 0 );
