Custom MySQL SELECT / UPDATE / INSERT / DELETE

Folks,

I have the need to make multiple forms on mysite. One is for an customer contact/addressbook.
I can write PHP code that does these entries in to a MYSQL DB, BUT...

I never done this with Modx.

Do I need to create a new DB for my use?
Can it use the existing Modx DB, but another table?

OR is Modx smart enough to manage my custom fields and values inside its existing structure ?

Any good documentation for a newbe ?

you can use formit for forms, it saves the data to the db under a special table.

if you need to store user data you can use an extra from BobRay called ClassExtender. It makes the tables as well, custom tables for user data [ed. note: nuan88 last edited this post 5 years, 2 months ago.]
