WooCommerce自动分配产品类别和产品状态[重复]

custom-taxonomy hook-woocommerce woocommerce wordpress php

iceiceicy · 技术社区 · 6 年前

我试图创建所有这些if语句:

如果勾选了产品类别A,则类别B将自动不勾选,产品状态变为“缺货”。
如果未选中产品类别A,则类别B将自动选中。

到目前为止,除了“缺货”部分,这两种说法都有效。有什么想法吗 ?

add_action( 'save_post', 'auto_add_product_category', 50, 3 );
function auto_add_product_category( $post_id, $post, $update ) {

    if ( $post->post_type != 'product') return;

    if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE )
        return $post_id;

    if ( ! current_user_can( 'edit_product', $post_id ) )
        return $post_id;

    $term_id_A = 116; //category A
    $term_id_B = 1459; //category B
    $terms = get_the_terms( $post_id, 'product_cat' );
    $term_ids = wp_list_pluck( $terms, 'term_id' );

    if(in_array($term_id_A, $term_ids) && ($key = array_search($term_id_B, $term_ids)) !== false) {
        unset($term_ids[$key]);
    } elseif(!in_array($term_id_A, $term_ids) && !in_array($term_id_B, $term_ids)) {
        $term_ids[] = $term_id_B;
    }
    wp_set_post_terms($post_id, $term_ids, 'product_cat');
}

if(in_array($term_id_A, $term_ids) && ($key = array_search($term_id_B, $term_ids)) !== false) {
    //remove term A from the terms array:
    unset($term_ids[$key]);
    //set stock level to zero:
    $out_of_stock_staus = 'outofstock';
    // 1. Updating the stock quantity
    update_post_meta($post_id, '_stock', 0);
    // 2. Updating the stock quantity
    update_post_meta( $post_id, '_stock_status', wc_clean( $out_of_stock_staus ) );
    // 3. Updating post term relationship
    wp_set_post_terms( $post_id, 'outofstock', 'product_visibility', true );
    // And finally (optionally if needed)
    wc_delete_product_transients( $post_id ); // Clear/refresh the variation cache

} elseif(!in_array($term_id_A, $term_ids) && !in_array($term_id_B, $term_ids)) {
    $term_ids[] = $term_id_B;
