Auto Populate Third Party Component's Form Using Substitution or Query?

I have a third party component that my users use to submit support tickets. This component allows me to have custom fields as part of it's form being submitted.

I would like to auto populate a text field within that form being submitted with a CB Custom field that I have created within the CB user profile of the logged in user (e.g. "cb_companyname" being the company that the user works for).

I'm assuming I can use either CB Substitution or a database query to get what I need? How would I do this?

I'm also assuming that I would have to modify this component's form in order to autopopulate that text field with that CB value? Possibly making it a read-only field with the default value being the CB value?

How do I do this?

In my search for an answer, I found this link but not sure if it will help, as I'm not using RSForm: www.rsjoomla.com/support/documentation/view-article/371-autopopulate-a-field-from-community-builder.html

Your extension would need to integrate with CB to allow for that. Even then you'll need to ask the developers of your extension as we did not develop it I can't advise you on its usage.

Ok. Thanks, I will ask them.

Is it possible to use the CB Substitution to populate a form's text field, that is within the Joomla framework? Or do I need to query the database directly?

Has anyone populated a form using CB Substitutions?

Substitutions can only be used where the API is directly integrated. So no you can't use them anywhere. Your extension would need to specifically pass the value through CBs substitution API. A direct database query can also work if you want the raw value of a field.
