spark-new-user-team.php

<?php

use App\Team;
use Laravel\Spark\Spark;
use Laravel\Spark\Interactions\Settings\Teams\CreateTeam;

//Create a User
$sparkUser = Spark::user();

$sparkUser->forceFill([
  'name' => 'Joe Bloggs',
  'email' => '[email protected]',
  'password' => bcrypt('superPassword'),
  'email_verified_at' => Carbon::now(),
  'last_read_announcements_at' => Carbon::now(),
  'trial_ends_at' => Spark::onlyTeamPlans() ? null : Carbon::now()->addDays(Spark::trialDays())
])->save();

//Create a Team
Spark::interact(CreateTeam::class, [
  $sparkUser, [
    'name' => 'My Team Name', 
    'slug' => 'my-slug',
                    
  ]
]);
