Inserting data from session using codeigniter - php

Question

I'm just practicing using session in Codeigniter and i've got a Problem here's my controller
public function ajax_Addfees()
{
if($this->input->is_ajax_request())
{
$input = $this->input->post();
if($this->session->userdata('html')){
$html = $this->session->userdata('html');
}
$id = explode($input['fno']);
$html[$id] = ['amount' => $input['amount'], 'oldamount' => $input['deduction']];
$this->session->set_userdata('html', $html);
}
}
public function savetuition()
{
$this->Tuition_model->savefees();
redirect('tuitionsetup_con');
}
This is my model
public function savefees()
{
$fees = $this->session->userdata('html');
$feeslist = [];
if( !empty($fees) ) {
foreach ($fees as $key =>$value) {
array_push($feeslist, [
'amount' => $value['amount'],
'oldamount' => $value['oldamount'],
'f_no' => $key,
'sy_no' => $this->session->userdata('sy'),
'level_no' => $this->session->userdata('lvl'),
'id' => $this->session->userdata('id')
]);
$this->db->insert_batch('tuition', $feeslist);
} }
}
Well what I'm trying to do is to save data from session->set_userdata('html') to my database using codeigniter.
There's no error but it doesn't save data to database

You need to modify your model as:
public function savefees() {
$fees = $this->session->userdata('html');
$feeslist = array();
if( !empty($fees) ) {
foreach ($fees as $key =>$value) {
$feeslist[$key]["amount"] = $value['amount'];
$feeslist[$key]["oldamount"] = $value['oldamount'];
$feeslist[$key]["f_no"] = $key;
$feeslist[$key]["sy_no"] = $this->session->userdata('sy');
$feeslist[$key]["level_no"] = $this->session->userdata('lvl') ;
$feeslist[$key]["id"] = $this->session->userdata('id') ;
}
}
$this->db->insert_batch('tuition', $feeslist);
}
