Echo Joomla 3.4 GroupId

Question

I'm very new to Joomla and PHP, however I'm attempting to echo the logged in users assigned groups (group id 58-62, 72). A user can only be in one of those groups at any point and time. Below is the code I'm using. It doesn't display any errors, and echos the first line, but no echo based off groupid. Also, the print_r doesn't return any data.

Any guidance on what I'm certain is a silly mistake on my part would be appreciated.

$groups = $user->get('groups');
print_r($groups);
if($groups) {
    echo "Echo user Group Name : ";
    if (isset($groups[62])) echo " - Group 62 <Br/>";
    if (isset($groups[61])) echo " - Group 61 text <Br/>";
    if (isset($groups[60])) echo " - Group 60 text <Br/>";
}else{
    echo 'Not logged in<Br/>';
}
}

I guess you first have created the user object.

$user = JFactory::getUser();

Then the $user->group is an array, not an object, and it will contain all the usergroups a user belongs. Therefore the $group->id is wrong (enable error reporting so you can see any errors).

Do a print_r($user->group), so you will be able to see the full array and its key/values, and decide what you want to do later with your logic.

Keep in mind that all users (even guests) will belong to a user-group, so a groups will always exist.

You could check against your desired usergroups with something like:

if (in_array(62, $groups)) {// do something here}

Or you can always loop through an array :

<?php foreach ($groups as $group) : ?>
 // do something
<?php endforeach; ?>
