php - WordPress：保存用户元以在保存时发布元

问题描述

我想在保存后将一些用户元数据添加到帖子（在我的情况下为 WooCommerce 产品）中。我想这是最好的方法？

我找到了一个这样的解决方案：https ://wordpress.stackexchange.com/a/273271/96806

但它似乎只这样做了一次？

这是代码：

function update_post_meta_with_user_meta() {
         //setup arguments to only get users with author role
         $user_args = array( 
                          'role' => 'author', 
                          );
        $authors   =  get_users( $user_args );
        //the below foreach could be replaced by adding something like:
        // fields => array( 'ID' ) to $user_args

       //instead I am just going through returned array of WP_User objects 
       //  and putting IDs into array
        foreach ( $authors as $a ) {
            $author_ids[] = $a->ID;
        }

       //setup post query arguments to only give us posts with authors in author_id array
       //which means only posts that have an author with the WP role of author
       // should exclude Editors, Admins, etc. that maybe have authored posts
        $post_args = array(
                          'author__in' => $author_ids,
                        );

        //a new WP_Query with these args   
        $post_query   = new WP_Query( $post_args ) ) );

        //make sure we have posts returned
        if ( $post_query->have_posts() ) {

            //loop
            while ( $post_query->have_posts() ) {

                $post_query->the_post();

                //set $post_id variable to current post
                $post_id = get_the_id();

                //get author meta for author of current post
                $author_genere = get_the_author_meta('genere');

                //update the meta of the current post (by ID) 
                //  with the value of its author's user meta key
                update_post_meta( $post_id, 'genere', $author_genere );
            }

            //reset the postdata
            wp_reset_postdata();
        }

    }
    //hook the above to init
    add_action( 'init', 'update_post_meta_with_user_meta' );

保存帖子/产品时有什么办法吗？

解决方案

虽然您的答案可能是“解决方法”，但它包含一些不必要的步骤，并且有一个更合适的钩子。

  • woocommerce_admin_process_product_object- 在后端保存产品时保存产品元数据：
function action_woocommerce_admin_process_product_object( $product ) {
    $vendor_id   = $product->post_author;
    $vendor_info = get_userdata( $vendor_id );
    $vendor_name = get_user_meta( $vendor_id, 'pv_shop_name', true );
    
    // For testing purposes, delete afterwards
    $vendor_name = 'the_vendor_name';
    
    $product->update_meta_data( '_custom_product_vendor_name', $vendor_name );
}
add_action( 'woocommerce_admin_process_product_object', 'action_woocommerce_admin_process_product_object', 10, 1 );
