I'm not sure what you are trying to do?

Do you want to list the user roles in the footer in a block?

This function returns an array of record objects

$DB->get_records('role_assignments', ['userid' => $user->id]);

The footer property expects a string or html

$this->content->footer

So you will need to format the data first eg:

$roles = $DB->get_records('role_assignments', ['userid' => $user->id]); 
$this->content->footer = '';

foreach ($roles as $role) {
    $this->content->footer .= $role->roleid . ' ';
}

Having said that, the role_assignments table only has the role ids not the names. You could use an existing function instead.

$roles = get_user_roles(\context_system::instance());

$this->content->footer = '';

foreach ($roles as $role) {
    $this->content->footer .= $role->name . ' ';
}

  • Thanks Man, Works Like A Charm, Can You Explain what this (.=) means, if easy. – Mohammad-Ahmad Sep 13 '22 at 09:04
  • No probs :) Yeah `.=` is a string operator to concatenate 2 strings - the equivalent of `$footer = $footer . $role->name` - https://www.php.net/manual/en/language.operators.string.php – Russell England Sep 13 '22 at 13:08
