How to get a users Roles and how to list all WordPress roles in PHP

November 4, 2021May 5, 2017 by louie171

This code is handy if you want to find out a users role/s. You could expand it and check if a user has a given role or similar.

$user_info = get_userdata(2152);
echo 'Username: ' . $user_info->user_login . "\n";
echo 'User roles: ' . implode(', ', $user_info->roles) . "\n";
echo 'User ID: ' . $user_info->ID . "\n";

$allroles = get_editable_roles();

foreach ($allroles as $k => $v) {

    echo "<br>role = $k ";
}

function get_editable_roles() {
    global $wp_roles;

    $all_roles = $wp_roles->roles;
    $editable_roles = apply_filters('editable_roles', $all_roles);

    return $editable_roles;
}

$user_info = get_userdata(2152);

echo 'Username: ' . $user_info->user_login . "\n";

echo 'User roles: ' . implode(', ', $user_info->roles) . "\n";

echo 'User ID: ' . $user_info->ID . "\n";

$allroles = get_editable_roles();

foreach ($allroles as $k => $v) {

echo "<br>role = $k ";

}

function get_editable_roles() {

global $wp_roles;

$all_roles = $wp_roles->roles;

$editable_roles = apply_filters('editable_roles', $all_roles);

return $editable_roles;

}
