        static  $count=0;
        if (!empty($this->data)) {

        $students = $this->Session->read('Student');
        if (!$students) {
            $students = array();


        }
        $students[] = $this->data['Student'];/* data */
        $this->Session->write('Student', $students);
        $this->Session->write('student_count',$count);

Add the Session helper to your view. The code to access the student_count variable would be

$session->read('student_count');

The general syntax is

$session->read('var_name');

Also, you should still be able to access variables with the $_SESSION superglobal. CakePHP is still PHP! But yes, this answer is the proper way to do this while adhering to CakePHP conventions.

$student_list = $this->Session->write('Student', $students);
$student_count = $this->Session->write('student_count',$count);

$this->set('$student_list',student_list);
$this->set('$student_count',student_count);

use the student_list and student_count in view page .
