cannot pass data from form to model zend 2.3 - php

Question

I am trying to insert data into seviral tables using tablegateway. I am getting the following error.
Fatal error: Call to a member function saveStudent() on a non-object in C:\xampp\htdocs\disability\module\Admin\src\Admin\Controller\AdminController.php on line 48
I tryed to implement the solution given here Zend\Form: Call to a member function insert() on a non-object in Zend/Form/Fieldset.php

<?php
namespace Admin\Form;
use Zend\Form\Element;
use Zend\Form\Form;

{
public function __construct($name = null)
{
// we want to ignore the name passed
// parent::__construct('addstudent');
parent::__construct('AddstudentForm');

}
What could be wrong with that. Or what info do you need?

Answer 1

You have a typo in your getStudenTable() method and therefore $this->getStudentTable() returns null.
$this->studentTable = $sm->get('Admin\Model\StudentTable');
should be
$this->StudentTable = $sm->get('Admin\Model\StudentTable');
