This is the scenario:

I'm using a form to generate a query to a MySQL database, everything is working fine except that the data is shown in a blank page.
What I want to do is to show the Query Result in the same page where the form is. In this case I can't use Director::redirectBack() because the Sql Result will not be displayed.

Is there any way to solve this?

This is the page structure:

Menu 1: Queries
Menu 2: Common Queries: --> Form

Thanks in advance.-
