How to catch an id from sfUser?

问题

I'm working with symfony 1.4 & i use sfDoctrineGuardPlugin as a tool for authentifications.

I want to catch the Id of user in order te store it in my table.

After a small research, I guess I have to use that expression : getUser()->getGuardUser()->getId().

What i looking for is how to invest that expression for my target.

回答1:

if the user is authenticated, yes, you can use:

// inside an action
$id = $this->getUser()->getGuardUser()->getId();

// inside a template
$id = $sf_user->getGuardUser()->getId();

If the user is not authenticated, it'll throw an error.

Depends from where you are calling.

From the 'view':

echo $sf_user->getAttribute('user_id', null, 'sfGuardSecurityUser' );
echo $sf_user->getUsername();

From the 'controller' (as mentioned by Tom above):

echo $this->getUser()->getGuardUser()->getId();
echo $this->getUser()->getGuardUser()->getUsername();

(First line is 'id', second is 'username')
