How to Insert/Edit Relationship Field Manually? What's this Field ID?

Oh,

I've just made a discovery about the MB Frontend form - there must not be the spaces between the multiple IDs in the shortcode, only comas. (Despite the instruction you have made here https://support.metabox.io/topic/mb-relationships-mb-frontend-submission/#post-24285).

This shortcode works fine:
[mb_frontend_form id="prihlasky,termin-pro-prihlasku_relationships_to"]

(Yes, it turned out, I have to use TO not FROM - this part is still a bit confusing to me, it's really unintuitive to find out, which is which).

So, at least I can do it via MB Frontend. But I would really like to use Fluent Forms, because of it's other features. Is it possible to map the relationship there? Does the relationship field have its record in the wp_postmeta table? Or am I able to at least populate it via some helper PHP function?

Thanks
Petr

Hi Long,

OK, forget about the Fluent Forms.
How can I, on my own, edit the relationship field manually using PHP code?

Thanks

Hi Long,

Well, to be honest, I did expect something more specific than a link to the superlong documentation on how to CREATE the relationship table.

Again, I wanted to EDIT the connection of already created relationship. I have created the relationship named "termin-pro-prihlasku" which interconnects 2 CTPs "courses" and "atendees".

In ACF it's quite straightforward, it's basically the same like editing all the other custom fields:

update_field('relationship_field', $value, $post_id);

After reading several pages of the documentation I've found the single line of code with very little explanation:

MB_Relationships_API::add( $from, $to, $id, $order_from = 1, $order_to = 1 );

It is based in the section here: https://docs.metabox.io/extensions/mb-relationships/#creating-connections-programmatically (in fact, this was the link, I was looking for).

Could you give me some example on how to uses it?
- Does it work only for creating the new relationships?
- What if I want to CHANGE some existing relationship?
- What are the two "$order" parameters for?

Thanks again
Petr

Hi Long,

thanks for your reply, it seems to be working now.

Just a little additional question: is it necessary to use the $order_from and $order_to?
I'm using this code and it seems to be working fine:
MB_Relationships_API::add( $postId, $termId, 'termin-pro-prihlasku');

Thanks
Petr
