创建新的自定义帖子时创建Wordpress用户

Question

我想从前端和后端创建自定义帖子。当我创建帖子时，我想创建用户。在前端，我使用表单和wp_insert_post，所以它创建后，我需要。在后台，我使用以下代码:

add_action( 'publish_user_contact', 'custom_post_user_create', 1, 3);
function custom_post_user_create($post_id){
$user_login_id = 'user_'.random_int(100000, 999999);    
update_post_meta($post_id, 'idr_contact_user_id', $user_login_id); 
$password = wp_generate_password( 10, true, true );
if (!empty($_POST['contact_email'])){
$userdata = [
'user_login'      => "$user_login_id",
'user_pass'       => "$password",     
'user_email'      => $_POST['contact_email'],    
'display_name'    => sanitize_text_field( $_POST['contact_first_name'] .' '. $_POST['contact_last_name'] ),     
'first_name'      => sanitize_text_field( $_POST['contact_first_name'] ),
'last_name'       => sanitize_text_field( $_POST['contact_last_name'] )   
];
} else {
$userdata = [
'user_login'      => "$user_login_id",
'user_pass'       => "$password",  
'display_name'    => sanitize_text_field( $_POST['contact_first_name'] .' '. $_POST['contact_last_name'] ),     
'first_name'      => sanitize_text_field( $_POST['contact_first_name'] ),   
'last_name'       => sanitize_text_field( $_POST['contact_last_name'] )   
];
}
$user_id = wp_insert_user( $userdata );
}

当我尝试编辑帖子时，它会创建更多的用户。我尝试使用new_to_publish，但它不起作用(用户不创建)。我尝试使用save_post，但它也会复制。

如何防止重复?

尝试为自定义字段添加检查，那么在编辑帖子时将不会执行代码。

add_action( 'publish_user_contact', 'custom_post_user_create', 1, 3);
function custom_post_user_create($post_id){
$user_login_id = 'user_'.random_int(100000, 999999); 
if(get_post_meta($post_id, "idr_contact_user_id", true) ) {
return;
}
update_post_meta($post_id, 'idr_contact_user_id', $user_login_id); 
$password = wp_generate_password( 10, true, true );
if (!empty($_POST['contact_email'])){
$userdata = [
'user_login'      => "$user_login_id",
'user_pass'       => "$password",     
'user_email'      => $_POST['contact_email'],    
'display_name'    => sanitize_text_field( $_POST['contact_first_name'] .' '. $_POST['contact_last_name'] ),     
'first_name'      => sanitize_text_field( $_POST['contact_first_name'] ),
'last_name'       => sanitize_text_field( $_POST['contact_last_name'] )   
];
} else {
$userdata = [
'user_login'      => "$user_login_id",
'user_pass'       => "$password",  
'display_name'    => sanitize_text_field( $_POST['contact_first_name'] .' '. $_POST['contact_last_name'] ),     
'first_name'      => sanitize_text_field( $_POST['contact_first_name'] ),   
'last_name'       => sanitize_text_field( $_POST['contact_last_name'] )   
];
}
$user_id = wp_insert_user( $userdata );
}
