如何在cakePHP中将同一对象的多个条目添加到会话中

Question

我有一个addstudent.ctp文件来添加学生

echo $this->Form->create('Student');
echo $this->Form->input('FirstName');
echo $this->Form->input('LastName');
echo $this->Form->end('Register'); 

echo $this->Form->create('Address',array('controller'=>'addresses','action'=>'addaddress'));
echo$this->Form->end('NextAdressDetails',array('controller'=>'addresses','action'=>'addaddress')); 

点击它之后会添加StudentsController的方法。必须将学生对象添加到会话中，并且应该重定向到同一页面。这样我就可以添加尽可能多的学生，所以我的问题是如何点击注册按钮，将多个学生添加到会话中。

Answer 1

$students = $this->Session->read('Students');
if (!$students) {
    $students = array();
}
$students[] = /* data */;
$this->Session->write('Students', $students);
