How to know if user is logged in from inside template code

Tuesday 15 July 2008 9:08:39 pm

Hi all,

Sorry for the simple question, but I've googled a lot and couldn't find how to do it.

Inside a template, what is the best and faster way to know if a user is logged in at the website?

I want to limit some functionallity of my website to logged in users.

In a website made without Exponential we probably could check it using $_SESSION variables. What about with Exponential?

Btw, I found a fetch function that appears to do that:

{if fetch( 'content', 'access', hash( ...) ) }

{/if}

Should I use that or there is a better solution?

Thank you

Or if you only need to know if the user is logged in (no need for user id or user name), then use $current_user.is_logged_in as cache key.

Also note that inside node/system templates you'll need to fetch the user first, so use something like this first*:

{if is_unset( $current_user )}
    {def $current_user = fetch('user', 'current_user') }
{/if}

But if you do want to check if a user has access to a certain module / function, then fetch('content', 'access') is a cleaner solution.

* node templates use content view cache, witch is unique pr user rights, but not user id. So you have to disable view cache (search for cache_ttl) if you need to use name / id in a node template.
