Problem:

The problem here is that the custom fields are appearing on every post type.

Solution:
If you go to Toolset -> Custom Fields and edit your field group, under Appears On you should be able to specify the post types that the custom field group should appear on.

This should allow you to resolve the issue and restrict your custom fields to only appear on one post type.

Problem:

I am using the cred_form_validate hook to force mandatory taxonomy fields.

Solution:

Since the taxonomy field value is an array, you can check the first item of array value, for example:

The issue here is that the user wanted to know if it was possible to take payments using our Toolset Forms plugin without having to install a 3rd party plugin.

Unfortunately no you are not able to take payments using our Toolset Forms plugin without the assistance of a 3rd party plugin.

Currently the only plugin we have payment integration with is Woocommerce.
