Question

This must be an easy one but I can’t find documentation for it online.

I’m trying to use the l() function in Drupal to create a dynamic link. What’s the syntax?

At the moment I have:

l('Destination',"path/$user->uid/category")

which points to:

path/%2Fcategory

Answer 1

first of all, if you’re working within a function, you’ll need to get access to the global user object.

Secondly, if the user is anonymous/not logged in, the $user->uid might not be set or be 0.

lastly to prevent errors, it is common to concatenate variables together with strings

global $user;
if ($user->uid)
{
  l('Destination', 'path/'.$user->uid.'/category')
}
