Advice on Php codeigniter insert query - php

Question

I have a form and it's been bugging for a while now, when i have all the information filled up in the forms it seems to insert it very quick, however if one or more fields are empty it doesn't work at all
the query i am using to insert into the database is. i am trying to figure out if i can use Insert_delay and maybe it will solve the problem? any possible solutions or changes i need to do
function student($param1 = '', $param2 = '', $param3 = '')
{
if ($this->session->userdata('admin_login') != 1)
redirect('login', 'refresh');
if ($param1 == 'create') {
$data['name'] = $this->input->post('name');
$data['sex'] = $this->input->post('sex');
$data['address'] = $this->input->post('address');
$data['phone'] = $this->input->post('phone');
$data['email'] = $this->input->post('email');
$data['password'] = $this->input->post('password');
$data['year'] = $this->input->post('year');
$data['rate'] = $this->input->post('rate');
$data['class_id'] = $this->input->post('class_id');
$data['class_id2'] = $this->input->post('class_id2');
$data['class_id3'] = $this->input->post('class_id3');
$data['class_id4'] = $this->input->post('class_id4');
$data['parent_id'] = $this->input->post('parent_id');
$data['roll'] = $this->input->post('roll');
$this->db->insert_('student', $data);
$student_id = $this->db->insert_id();
$this->session->set_flashdata('flash_message' , get_phrase('Student_added_successfully'));
$this->email_model->account_opening_email('student', $data['email']); //SEND EMAIL ACCOUNT OPENING EMAIL
redirect(base_url() . 'index.php?admin/student_add/' . $data['class_id'], 'refresh');

In controller
function student($param1, $param2 $param3 )
{
if ($this->session->userdata('admin_login') != 1)
{
redirect('login', 'refresh');
}
else
{
if($param1 == 'create') {
$result = $this->model_name->insert_data();
if ($result != FALSE) {
$email => $this->input->post('email');
$confirm = $this->email_model->account_opening_email('student', $email); # do same as insert
if ($confirm != FALSE) {
$this->session->set_flashdata('flash_message' , get_phrase('Student_added_successfully'));
redirect(base_url() . 'index.php?admin/student_add/' . $data['class_id'], 'refresh');
}
else
{
echo "Mail send failed";
}
}
else
{
echo "param1 is not create";
}
}
}
}
In Model
public function insert_data()
{
# to isert data, I add them in to one array
$data = array(
'name' => $this->input->post('name'),
'sex' => $this->input->post('sex'),
'address' => $this->input->post('address'),
'phone' => $this->input->post('phone'),
'email' => $this->input->post('email'),
'password' => $this->input->post('password'),
'year' => $this->input->post('year'),
'rate' => $this->input->post('rate'),
'class_id' => $this->input->post('class_id'),
'class_id2' => $this->input->post('class_id2'),
'class_id3' => $this->input->post('class_id3'),
'class_id4' => $this->input->post('class_id4'),
'parent_id' => $this->input->post('parent_id'),
'roll' => $this->input->post('roll')
);
if (!$this->db->insert('student', $data)) {
# insert FAILED
return FALSE;
}
else{
# insert SUCCESS
$slast_id = $this->db->insert_id(); # get last insert ID
return = $slast_id;
}
}
