in an action you can do:

$this->logMessage($message);

or you can do this everywhere:

sfContext::getInstance()->getLogger()->info($message);

You shouldn't use it in a template - that would break the MVC model.

Anyway, you could use the Debug Helper in Templates see:

http://www.symfony-project.com/book/trunk/16-Application-Man agement-Tools#Debugging

<?php use_helper('Debug') ?>
...
<?php if ($problem): ?>
  <?php log_message('{sfAction} been there', 'err') ?>
  ...
<?php endif ?>

What has logging to do with MVC? Nothing!

al_n, I can't quite tell if you're trying to be rude, but it sounds like it. Surely you can manage a more diplomatic tone than that?

MVC, as I am sure you know, is about the separation of concerns between logic and presentation. I regard application logging as logic that firmly does not belong in the presentation layer, so I would still maintain that my comment was correct. Debugging logging, on the other hand, can go anywhere, which is perhaps what you had in mind.

My dear halfer,
I didn't intend to be rude but when people are asking about logging in order to trace code execution then I assume they are trying to debug something. You can surely understand that debugging is also something you are doing in your presentation layer. More then that, logging is not logic, its just .... logging and it is not breaking the definition of the MVC design pattern if it happens in the view.
