Hot to get user's roles

Posted by Xano on 

I'd like to know if there is a way to determine the roles of a given user without using a customized SQL query for that. In the forum ht only thing I've found was $user->role (which worked for that topicstarter who was using Drupal 4.7) but that doesn't do the trick for me.

To get the name of the role, you would have to do a simple query.

Here's what I put in a block to get the role name:

<?php
  global $user;
  $role = db_result(db_query('SELECT r.name FROM {users_roles} ur LEFT JOIN {role} r ON r.rid=ur.rid WHERE ur.uid=%d LIMIT 1', $user->uid));
  print $role;
?>

If you just want the role id ("rid"), you can leave out the join stuff.

Hey Nancy,

I've already done this with a customized SQL query in the past, but now I've found this solution for 4.7 I was wondering if there was something similar for 5.x. Would be pretty stupid if there's a feature in 4.7 for this which doesn't exist in 5.x anymore.

Thanks for the tip anyway :-)

I just looked at user.module and came up with this:

<?php
  global $user;
  print 'roles: '.implode(', ', $user->roles);
?>

okaaaaaaaaaaay............. I'm pretty sure I tried print_r($user->roles) to test the variable, but no result showed itself on screen. Must have done something wrong. Thanks for giving me this piece of code. Now I know it was I who was wrong and it wasn't Drupal :-P

Q) but what does implode do?
A) it returns a string created by joining every element in an array with separator (in this case ', ')

Q) how do I modify this code to ignore the default authenticated role?
A) ???

implode(', ', array_slice($user->roles, 1))

If you want to do a check on a users role when multiple roles may exist for that user, you can do it with in_array():

<?php
if(in_array('role_you_want_to_check_for', $user->roles)) {
     return true;
} else {
     return false;
}
?>

I'm a bit late here, but this works for me:

<?php
global $user;
if (array_key_exists('ROLE ID', $user->roles)) {
     return true;
} else {
     return false;
}
?>

NancyDru commented 

Why not just use user_access() if you want to know if the current user has that permission.

They might not be checking for permissions. I found this page while looking to set dynamic product pricing based on a retailer's role. They all have permission to view the product page but they don't always get the same margin.

hello

i am not php programer, and new in drupal of course, actually i'm ussing the pdf id card module, works fine, but i can't print the role user. i mean, i have many profiles with different roles to print.

the code is

$pdf->SetFont('freeserif','',8);
$pdf->setxy(53,5);
$pdf->Image($account->picture, 4,18, 33,40);
$pdf->Cell(100,33,strtoupper($account->profile_1nombre),0,0,"left",0,0);
$pdf->setxy(80,5);
$pdf->Cell(100,33,strtoupper($account->profile_2nombre),0,0,"right",0,0);
$pdf->setxy(53,5);
$pdf->Cell(100,43,strtoupper($account->profile_1apellido),0,0,"right",0,0);
$pdf->setxy(80,5);
$pdf->Cell(100,43,strtoupper($account->profile_2apellido),0,0,"right",0,0);
$pdf->setxy(53,5);
$pdf->Cell(100,63,strtoupper( THE MISSING CODE),0,0,"right",0,0);

Excuse my english, spanish is my native laguage ...

As long as you have the UID (User ID) you want to get roles for, you can user the user_load function to get all the values attached to that UID, and then print_r the roles array to see what is in it... like this:

<?php
$user_current_uid = // insert the userID here;
$user_details = user_load($user_current_uid);
// output all the user roles arrays items
print_r($user_details->roles)
?>

user_load is a *very* expensive function call. Use sparingly. The other solution posted above does not require these and is probably much more efficient.

NancyDru commented 

User_load takes a different parameter in D6.

I'm going to hazard a guess that $account (line 3) is the user object. $account->roles will have all the user's roles in it.

If you have PHP filter module enabled, you can make a block named "User roles" and put this in content:

<?php
global $user;
foreach($user->roles as $role) {
print "<div>".$role."</div>";
}
?>

Don't forget to select PHP code as a Text format!
This will print all roles of a curent user.
Works on D7. Use this for testing purposes.
