Redirect client to new custom page after login to client area

[Rahat_Arif]

Hi, 

It is my goal to create a hook that, when a new client clicks on the Complete Order button after first ordering, the client is forced to log into the client area and then redirected to my custom page without first seeing the homepage. Please note: This is only for new clients

Thanks in advance

Try this one 

<?php
use WHMCS\User\Client;

add_hook('ClientAreaPage', 1, function($vars) {
    if (Client::isLoggedIn()) {
        $userId = (int) Client::getClientID();
        $clientDetails = Capsule::table('tblclients')
            ->where('id', $userId)
            ->first();
        $isFirstOrder = ($clientDetails->orders == 1);
        if ($isFirstOrder) {
            header("Location: https://yourdomain.com/custom-page-url");
            exit;
        }
    }
});
