Topic Tag: Post-relationship

Problem:

I have:
parent post type: "contatto"
child post type "corso"
custom field "data-inizio corso" in child "corso"
custom field "data-ultimo-corso" in parent "contatto"

I would like that when filled "data-inizio-corso" the value is copied in "data-ultimo-corso" updating or creating the post.

Solution:

Types plugin is using a custom field "_wpcf_belongs_[parent-slug]_id" to store the parent post ID, for example, if the parent post type is using slug "contatto", then in single child "corso" post, there is a hidden field "_wpcf_belongs_contatto_id", the filed value is parent post ID, so if "$post_ID" is a child "corso" post ID, you can get the parent "contatto" post ID with PHP codes:

$contatto_id = get_post_meta($post_ID, '_wpcf_belongs_contatto_id', true);

Then use the $contatto_id to update the custom field "data-ultimo-corso" to what you want.

Problem:

In my site i have custom post type contacts, every contact can attend to 1 or more courses (usually 1 to 5). We'll plan to have 10.000-30.000 contacts.

Instinctively i was thinking to use method of advanced custom field and add repeater fields (course type, level, date, ecc...)

I read also some post on this forum, and some article from toolset documentation on group fields (many to many relationship or one to many)

I'm a little confused on options and my question is:
in my case what is the correct option i should use with toolset (especially from database point of view)?

Solution:

It depends on your settings.

I assume we are talking about this case:
Two custom post types:
- contacts
- courses
One "courses" post can connect with multiple "contacts" posts
One "contacts" post can connect with multiple "courses" posts
If it is, I suggest you try to setup many-to-many relationship between custom post types:
- contacts
- courses

Problem:
Where to download the Toolset betas?

Solution:
The beta versions are available from your account downloads page: https://toolset.com/account/downloads/

You'll need to switch to the beta track, as shown in the screenshot below.

Problem:
There is a z-index problem with the relationship dialogs, making it impossible to select the required content.

Solution:
This arises from a conflict with the Slider Revolution plugin by Artbees.

They have a problem with their CSS which only they can fix.

Problem: I have a CRED form that allows users to create child posts. I would like to predefine the parent post so the User does not need to select it.

Solution: If you want to predefine values for a CRED field, you have 3 basic options:

1. Provide the value as a URL parameter. Link to the page containing the CRED form using the URL value to supply the correct parent ID, something like yoursite.com/cred-form-page?contatti=1234. Then update your parent contatti CRED field and add the urlparam attribute:

[cred_field field='_wpcf_belongs_contatti_id' post="iscrizioni" urlparam="contatti"]

This would predefine the contatti with ID 1234 as the parent of the new post.

2. Provide the value in the value attribute. You can use a hard-coded number or a shortcode in the value attribute to predefine the parent contatti ID:

[cred_field field='_wpcf_belongs_contatti_id' post="iscrizioni" value="1234"]

3. Write your own custom code with JavaScript and/or PHP. Note that there is no CRED JavaScript API, so the amount of support we can provide for custom JavaScript is fairly limited.

In all 3 cases, you can wrap the field in a hidden div if you want to hide the field from your Users:

<div style="display:none;">
[cred_field ...]
</div>
