The easy way to do transaction is to use it as a callback, this way it will be handle it automatically for you.
public function TestingRegistration(){
$now = \Carbon::now(); // Where is this use?
$faculty_user_account = [
'user_id' => '466297',
'name' => 'Hello',
];
$success = \DB::transaction(function () use ($faculty_user_account) {
$save_registration = \DB::table('users')->insert($faculty_user_account);
$view2 = \DB::connection('mysql_2')->table('users')->insert($faculty_user_account);
$view3 = \DB::connection('mysql_3')->table('users')->insert($faculty_user_account);
return (bool) $view2 && $view3;
});
if (! $success) {
return \Redirect::back()->with('errormessage', 'Unable to save.');
}
return \Redirect::back()->with('message',"Faculty Registration Successfull!");
}
PS: I can't remember what insert returns, let me check later to make sure it can be use like that for testing success.
