Problem:
The user would like to get the ID of the content template of a custom post in code.

Solution:
After the update to Toolset Blocks 1.5, we introduced a new way of handling single post pages with content templates. Now we have conditions and priorities to determine what content template to use on a post to display on its single post page. You will need to pass the post's object ($post) to it:

$template_id = apply_filters( 'wpv_content_template_for_post', 0, $post );

Problem:

- I would like to have a "number" field filled in automatically according to two other fields

- I would like to limit a "number" field according to a result.

Solution:

If you are using Toolset Forms plugin to setup post forms, you can consider custom JS codes, for example:
