Hi there 🙂

How can users select parent posts (many to many) in a post form?

Thank you 🙂

Hi,

Welcome to Toolset support. In the typical workflow, an edit post Form does not allow you to manage many-to-many (M2M) relationships, it only edits the main content, taxonomies, and custom fields of the post itself. Normally M2M relationships are managed in a separate Relationship Form, which does not allow editing the main post contents, taxonomies or custom fields. Those processes are usually kept separate. In a one-to-many relationship, an edit post form for the child post type will allow you to choose a parent post, but in a M2M relationship the situation is more complex and requires a separate Form as explained in our lessons here:
https://toolset.com/course-lesson/front-end-relationship-forms-for-connecting-posts/

So the preferred solution here is a separate Relationship Form to manage M2M relationships. If you want to implement a more custom solution that allows you to manage M2M relationships directly in an edit post Form, we have several PHP APIs available for inspecting and managing post relationships with Forms submissions:

Please consider that we can not provide custom code as it is outside of our support scope. You are welcome to ask for help from a contractor:

Thanks.

Ok, thank you, Christopher.

And could you just tell me how you consider an approach to display both forms side by side, to make it look like one form, and to trigger one submission by the other?

Hi Achim,

That is not possible with conventional Toolset features.

One idea can be to get the results of first form submission in cred_save hook, and feed it via some sort of JavaScript, localization to the second form and forced to submit it via JavaScript.

That is way complicated, and as I mentioned in the previous reply needs a professional developer to do so.

Thank you very much.
