Hello and thank you for contacting the Toolset support.
I do not think this is possible. A Toolset Form needs to be generated in order to be used. There are some hidden data that are being used and that will be generated each time, like nonces. Read more about nonces here https://codex.wordpress.org/WordPress_Nonces
I hope this answers your question, let me know if you have any further questions.
The form is generated through a shortcode or a Block if you are using the Blocks editor. You can use the do_shortcode function from WordPress, but you will need to load WordPress and the Toolset plugins to be able to generate the form. https://developer.wordpress.org/reference/functions/do_shortcode/
Loading WordPress core and plugins in a custom PHP file is not officially supported by WordPress, but you may find what suits you. Check this search results: hidden link
From what I understand so far. You would like to have the form on a page /form-here and you would like to submit it to another page /form-submitted-here, right?
This is not possible, the generated form and the form processing are both done on the same page, but you can configure the form to redirect to another page after form submit.
It may be possible to generate the form on a page and handle the submitting on another page, through custom coding, but this is not supported, and it may be complex or have side effects.
If you think I did not understand your question very well, please explains in detailed steps:
- I want to have ...
- I go to...
- I do...
- I want to get ...
I can't tell if it is possible or not. But I can say that it is not supported.
What I can say so far, is that a Toolset form is saved as a hidden custom post type 'cred-form' for post forms and 'cred-user-form' for user forms. As a custom post type, all the data about the form is saved inside the wp_postmeta table. I did a search on my local setup and here what I was able to find for a post form. Some setting sare saved as a serialized array. Check this screenshot hidden link
I suppose, that you will have to create forms with the Toolset editor and track what is saved on the database to understand how you can do it with your own editor.
