Php 将id保存到会话

我想在保存产品后将产品Id放入会话，但在读取会话时，我得到了错误的Id

foreach ($this->data['Address'] as $key => $ab) {
    $this->data['Product'][$key]['model'] = 'User';
    $this->data['Product'][$key]['foreign_key'] = $this->User->id;
    $this->Supplier->Brand->Type->create();
    $this->Supplier->Brand->Type->save($this->data['Product'][$key]);
    $this->Session->write('productId', $this->Supplier->Brand->Type->id);
}

如何获取产品id？

请尝试使用代码

foreach ($this->data['Address'] as $key => $ab) 
 {
$this->data['Product'][$key]['model'] = 'User';
$this->data['Product'][$key]['foreign_key'] = $this->User->id;
$this->Supplier->Brand->Type->create();
$this->Supplier->Brand->Type->save($this->data['Product'][$key]);

$lastid = $this->Supplier->Brand->Type->getLastInsertID()

$this->Session->write('productId', $lastid);
}

您正在保存集合中的最后一个id，因为每个连续循环都会覆盖上一个循环。这不是你想要的吗？是的，我想要最后一个身份证。。。。
