WP-通过save_post钩子将usermeta值更改为metabox值

Question

我有一个带有2个代谢盒的CPT。1=mv_facility_code2=mv_facility_email

所有用户都有dB列user_facility和user_facility_email

当一个站点管理员进入CPT并更改mv_facility_email时，我试图找到所有user_facility值与mv_facility_code匹配的用户，并将他们的元数据从user_facility_email中的值更改为新的mv_facility_email。

这是我正在尝试的，但不起作用。

add_action( 'save_post_cpt', 'mv_update_user_facility_details' );
function mv_update_user_facility_details() {
$facility_code = get_post_meta($post->ID, 'mv_facility_code', true);
$facility_email = get_post_meta($post->ID, 'mv_facility_email', true);
$args = array(
'meta_key' => 'user_facility',
'meta_value' => $facility_code,
);
$user_query = new WP_User_Query();
$users = $user_query->get_results();
if ( ! empty( $users ) ) {
foreach ( $users as $user ) {
update_user_meta( $user->user_id, 'user_facility_email', $facility_email );
}
};
};

如能理解我的错误，我们将一如既往地不胜感激。

您的代码存在一些问题。检查这个并阅读所有评论

add_action( 'save_post_cpt', 'mv_update_user_facility_details' , 10  ,3 );
/**
* @param WP_Post $post
* passing all 3 parameter to function
*/
function mv_update_user_facility_details($post_id , $post, $update) {
if (! $update ) return;
$facility_code = get_post_meta($post_id, 'mv_facility_code', true);
//make sure this is the updated data
$facility_email = get_post_meta($post_id, 'mv_facility_email', true);
//args never used
$args = array(
'meta_key' => 'user_facility',
'meta_value' => $facility_code,
);
//pass it to constructor
$user_query = new WP_User_Query($args);
$users = $user_query->get_results();

//i prefer do it like this , same thing just easier to read 
$users = get_users([
'meta_key' => 'user_facility',
'meta_value' => $facility_code,
]);
if ( ! empty( $users ) ) {
foreach ( $users as $user ) {
update_user_meta( $user->ID, 'user_facility_email', $facility_email );
}
};
};
