Converting array to Drupal format

Question

Hi all,

This statement gives me the value I want in Drupal (namely the last user role):

global $user; return (end($user->roles));

however I need to convert it to this format:

return array(
  0 => array('value' => value for value),
  // You'll usually want to stop here. Provide more values
  // if you want your 'default value' to be multi-valued:
  1 => array('value' => value for value),
  2 => ...
);

and I've got no idea how to (also, is this format a multidimensional array?)...

Any ideas? Thanks for any help, Theo.

Answer 1

I'm not sure what you are aiming for exactly. For the record the form of $user->roles is

array(
  rid => 'role_name',
  ...
)

Using the statement above, you actually don't get the late user role, but the user role with the highest id.

I'm guessing you want to get a format like this,you're not to clear about this.

array(
  0 => array(rid => 'role_name'),
  1 => array(rid => 'role_name'),
  ...
)

if that is the case you can get it with a simple foreach loop:

$result = array();
foreach ($user->roles as $key => $value) {
  $result[] = array($key => $value);
}
return $result;

Answer 2

Why not simply:

global $user;
print_r($user->roles);

That will show you a users roles. I'm not sure why you'd want the last one. It already returns in the format you are asking for. From there its up to you to extract the role you are looking for.

To move them into a keyed array:

global $user;

$result = array();
foreach ($user->roles as $key => $value) {
  $result[] = array($key => $value);
}
return $result;

Thanks for the help - you've made me understand this more now. It turns out that it wasn't working because you have to use an ID number and not a name. So the final code was:

global $user; return array( 0 => array('value' => end($user->roles)) );

So I guess that you are having to build a multidimensional array is it? for this to be in the correct format...
