To retrieve data about Plesk user, use the
pm_Client
class.

The
pm_Client
class represents a Plesk user account. This class supports retrieving
information about a user either by their ID or by their username:

• getByClientId()
• getByLogin()

Alternatively, the entire list of all users can be retrieved:

• getAll()

pm_Client also lets you identify a user’s account type:
administrator, reseller, or customer:

• isAdmin()
• isReseller()
• isClient()

The next method lets you retrieve any user information from the clients
table in the Plesk database psa:

• getProperty()

Finally, the following methods check for assigned permissions:

• hasAccessToDomain()
• hasPermission()
• hasCorePermission()
• hasAccessToPlan()

Storing and Retrieving User-specific Data

It is possible to store and retrieve arbitrary data for a specific user.
The following methods add new data records, retrieve existing data and
remove records that are no longer needed:

• getSetting()
• setSetting()
• deleteSettings()

Example: Retrieving information about the user

$client = pm_Client::getByClientId($id);
echo "Hello, {$client->getProperty('login')}";
if ($client->isAdmin()) {
    echo "You are admin";
} elseif ($client->isReseller()) {
    echo "You are reseller";
} elseif ($client->isClient()) {
    echo "You are customer";
}

Example: Retrieving user ID by username

$client = pm_Client::getByLogin($login);
echo "Your ID is {$client->getId()}";
