Try this,

$data['Semister'] =$this->input->post('Semister');
$data['Dept']     =$this->input->post('Dept');
$this->load->model('Upload_Result_Model');
$data['subjects']=$this->Upload_Result_Model->getAllSubjects($data['Semister'],$data['Dept']);
$data['student']=$this->Upload_Result_Model->getAllStudent($data['Semister'],$data['Dept']);
$this->load->view('Faculty/upload_mid_result',$data);

You can access all the variables directly in view like how you are accessing now.

In your controller use $data['semister'] = $Semister and $data['dept'] = $Dept

答

Sending data to view is easy

$this->load->model('Upload_Result_Model');

$semister   =   $this->input->post('Semister');
$Dept       =   $this->input->post('Dept');

$data['semister']   =   $semister;
$data['dept']       =   $Dept;
$data['subjects']   =   $this->Upload_Result_Model->getAllSubjects($Semister,$Dept);
$data['student']    =   $this->Upload_Result_Model->getAllStudent($Semister,$Dept);

$this->load->view('Faculty/upload_mid_result',$data);

$data array is applied php extract in view method and you can use indexes of array at view like this

echo $semister;
echo '<br>';
echo $dept;
echo '<br>';

echo '<pre>';   
print_r($subjects);
echo '<pre>';   
print_r($student);
