Get PDO lastInsertId() after method called - php

Question

In my code I use methods to insert data to MySQL database. The method then return either true or false.
If the method return true I would like to use lastInsertId() to run a second method.
Like
if($db->insertMethod($data)){
$lastId = $db->lastInsertId();
$db->secondInsertMethod($lastId, $data2)
}
db.class.php
public function insertMethod($data) {
$db = new DB();
$insert = //Run SQL insert
if($insert > 0 ) {
return true;
}else{
return false;
}
}
public function lastInsertId() {
return $this->pdo->lastInsertId();
}
In this case $db->lastInsertId(); will return 0. One workaround would be to have insertMethod to return this instead of just true but there must another way as well?

Edited!
the solution is correct
The data2 is linked to the data ?
you can also make :
public function insertMethod($data, $data2) {
$db = new DB();
$insert = //Run SQL insert
if($insert > 0 ) {
$this->insertMethod(this->lastInsertId(), $data2);
return true;
} else {
return false;
}
}
or if data2 is linked to the data
public function insertMethod($data) {
$db = new DB();
$insert = //Run SQL insert
if($insert > 0 ) {
$data2 = // get data2
$this->insertMethod(this->lastInsertId(), $data2);
return true;
} else {
return false;
}
}
public function insertMethod($id, $data) {
// your code...
}
or
public function insertMethod($data, $id = null) {
$db = new DB();
if($id == null)
// code to insert without id
else {
$insert = //Run SQL insert
if($insert > 0 ) {
$data2 = // get data2
$this->insertMethod($data2, this->lastInsertId());
}
}
}
The solutions are correct. For you to see who you think is the most appropriate in your situation.
