I feel really stupid asking this question, but if I want to make some changes to an existing variable in the controller before it is rendered in the template, such as $Content or $Title or a custom field such as $AuthorName for example, how can I do this? I just can't seem to find instructions on how to do this in the tutorials or the forums. Can someone point me to the right page that explains how to accomplish this?
If someone tells me to RTFM, I'm really sorry that I'm such an idiot, but I just cannot find any information about this anywhere on Google or the Silverstripe tutorials/forums, and I tried really really hard. So would very much appreciate it if you can point me to the right URL.
Thanks!
