How to use another object in templete

Question

Can we use other object's field in VF template, if yes then how? Please suggest.

Answer 1

Yes, you can use another object field using a component and for this you need to make a apex controller.

Answer 2

You can do that by creating a Visualforce Email Template with a Custom Controller.

Here are the steps:

1. Create a Custom Controller Apex class.
2. Create a Custom Component that has its controller attribute set to the class created in step #1.
3. Create a Visualforce Email Template that includes the Custom Component created in Step #2.

This is outlined with an example in the documentation Using Custom Controllers within Visualforce Email Templates.
