I have two post types in a one to one relationship. Both have expiration enabled. When Post A (which already has an expiry date) is amended (at a point in time when Post B has already been created), I want its expiry date to be changed to match the expiry date of Post B.
I've tried it like this:-
add_action('cred_save_data', 'save_data_form_519',10,2);
function save_data_form_519($post_id, $form_data) {
// This is the form that updates Post A
if ($form_data['id']==519) {
$related_post_id = toolset_get_related_post($post_id, 'a-b' );
$a_expiry = get_post_meta($related_post_id, '_cred_post_expiration_time', true);
// update expiry date
update_post_meta($post_id, '_cred_post_expiration_time', $a_expiry);
}
}
but this removes the expiry for the post.
I've double checked that the relationship exists but can't work out why this isn't functioning. Any ideas please? Thanks
Hello. Thank you for contacting the Toolset support.
Well - as I understand the form you currently editing is the parent post form. So, you want to update the _cred_post_expiration_time to the related post - correct? If yes:
Could you please try to use following code:
add_action('cred_save_data', 'save_data_form_519',10,2);
function save_data_form_519($post_id, $form_data) {
// This is the form that updates Post A
if ($form_data['id']==519) {
$related_post_id= toolset_get_related_post($post_id, 'a-b','child');
$a_expiry = get_post_meta($related_post_id, '_cred_post_expiration_time', true);
// update expiry date
update_post_meta($related_post_id, '_cred_post_expiration_time', $a_expiry);
}
}
Thanks for looking into this for me. I had to make a slight adjustment to your code and it works so thank you for your guidance here. Here's the final code:-
add_action('cred_save_data', 'save_data_form_519',10,2);
function save_data_form_519($post_id, $form_data) {
// This is the form that updates Post A
if ($form_data['id']==519) {
$related_post_id= toolset_get_related_post($post_id, 'a-b','child');
$a_expiry = get_post_meta($related_post_id, '_cred_post_expiration_time', true);
// update expiry date
update_post_meta($post_id, '_cred_post_expiration_time', $a_expiry);
}
}
I'm curious as to why I needed to add 'child' when retrieving the related post. I have other hooks containing this line (in one-to-many relationships). Should I be adding 'child' or 'parent' to these other hooks to avoid incorrect output even though this isn't indicated anywhere? I'd really like to understand this better please. Thanks.
The defult is parent , so whenever you want to have parent ID, if you will not pass the argument it's OK but when you want to have related child post ID, you need to pass child as argument as default is parent.
