Drupal: assign roles in user_save - drupal

Question

I can't find a solution or right example for something that should be quite simple: assign a role to an user when creating it, this is what I'm trying:
$edit = array(
'name' => $_POST['name'],
'pass' => $password,
'mail' => $_POST['email'],
'status' => 0,
'language' => 'es',
'init' => $_POST['email'],
array(2 =>'authenticated', 4=>'my custom role') //as id and named in role db table
);
user_save(NULL, $edit);
The user is not being created, how can I do this?
Thank you

Answer 1

You haven't named the roles member as such. Try his modified version:
$edit = array(
'name' => $_POST['name'],
'pass' => $password,
'mail' => $_POST['email'],
'status' => 0,
'language' => 'es',
'init' => $_POST['email'],
'roles' => array(
2 => 'authenticated',
4 => 'my custom role',
),
);
user_save(NULL, $edit);

Answer 2

And you can use objects to do that.
// Check if user's email is unique
if (!user_load_by_mail($_POST['email'])) {
$account = new stdClass;
$account->name = $_POST['name'];
$account->pass = user_hash_password($password);
$account->mail = $_POST['email'];
$account->status = FALSE;
$account->language = 'es';
$account->init = $_POST['email'];
$account->roles = array(
DRUPAL_AUTHENTICATED_RID => TRUE,
'Your custom role' => TRUE,
);
user_save($account);
}

Here is a hook I've written to add a role to a user when a new user is inserted:
<?php
function MYMODULE_user_insert(&$edit, $account, $category){
if (array_key_exists('profile_1', $account)) {
$is_university = FALSE;
if ($account->profile_sport_club['field_club']['und'][0]['value'] == 1 ) {
$is_university = TRUE;
}
if ($is_university) {
$uid = $account->uid;
$role_name = 'uni_club';
if ($role = user_role_load_by_name($role_name)) {
user_multiple_role_edit(array($uid), 'add_role', $role->rid);
}
}
}
}
?>
Thanks to this tip, it's now much simpler.

function first_user_insert(&$edit, $account, $category, $node){
$uid = $account->uid;
$role_name = 'role name';
if ($role = user_role_load_by_name($role_name)) {
user_multiple_role_edit(array($uid), 'add_role', $role->rid);
}
}
