Создать пользовательскую функцию для загрузки и вставки данных

Есть ли шанс, что я могу создать пользовательскую функцию для загрузки? У меня есть 2 функции, которые являются insert_content () и insert_officials. В этой функции есть код для загрузки изображения. Как я это сделаю, так как они имеют одинаковый код конфигурации.

публичная функция insert_content () {
$ data = array (‘success’ => false, ‘messages’ => array ());

    $name        = array('post_title','post_category','post_description');
$label       = array('Title','Category','Description');
$verify      = 'trim|required';
$this->validate($name[0], $label[0], $verify);
$this->validate($name[1], $label[1], $verify);
$this->validate($name[2], $label[2], $verify);
$this->form_validation->set_error_delimiters('<p class="text-danger">', '</p>');

if($this->form_validation->run()) {
$data['success'] = true;
} else {
foreach($_POST as $key => $value) {
$data['messages'][$key] = form_error($key);
}
echo json_encode($data);
exit;
}

$date = date('Y');
$month = date('m');
$upload_config = array (
'upload_path'  => './assets/uploads/'.$date.'/'.$month, 'allowed_types' => 'jpg|png|jpeg',
'max_size'     => '2048', 'max_width'    => '1536', 'max_height'   => '1024'
);

$this->load->library('upload', $upload_config);

if(!is_dir($upload_config['upload_path'])) {
mkdir($upload_config['upload_path'], 0777, TRUE);
}

if($this->upload->do_upload('post_image')) {
$data = array('upload_data' => $this->upload->data());
$image = $data['upload_data']['file_name'];

$data = array (
$name[0] => $this->pass($name[0]),
$name[1] => $this->pass($name[1]),
$name[2] => $this->pass($name[2]),
'post_image' => $image
);
$this->model->CreateContent($data);
}
}

//Officials
public function insert_officials() {
$data = array('success' => false, 'messages' => array());

$name   = array('official_fname','official_mname','official_lname','official_nickname','official_contact','official_position','official_barangay','official_address');
$label  = array('First Name','Middle Name','Last Name','Nickname','Contact','Position','Barangay','Address');
$verify = 'trim|required';
$number = 'required|regex_match[/^[0-9]{11}$/]';
$this->validate($name[0], $label[0], $verify);
$this->validate($name[1], $label[1], $verify);
$this->validate($name[2], $label[2], $verify);
$this->validate($name[3], $label[3], $verify);
$this->validate($name[4], $label[4], $number);
$this->validate($name[5], $label[5], $verify);
$this->validate($name[6], $label[6], $verify);
$this->validate($name[7], $label[7], $verify);
$this->form_validation->set_error_delimiters('<p class="text-danger">', '</p>');

if($this->form_validation->run()) {
$data['success'] = true;
} else {
foreach($_POST as $key => $value) {
$data['messages'][$key] = form_error($key);
}
echo json_encode($data);
exit;
}

$date = date('Y');
$month = date('m');
$upload_config = array (
'upload_path'  => './assets/uploads/'.$date.'/'.$month, 'allowed_types' => 'jpg|png|jpeg',
'max_size'     => '2048', 'max_width'    => '2048', 'max_height'   => '1024'
);

$this->load->library('upload', $upload_config);

if(!is_dir($upload_config['upload_path'])) {
mkdir($upload_config['upload_path'], 0777, true);
}

if (!$this->upload->do_upload('official_image')) {
$data = array('error' => $this->upload->display_errors('<span class="ti-remove"></span> '));

} else {
$data = array('upload_data' => $this->upload->data());
$image = $data['upload_data']['file_name'];

$data = array (
$name[0] => $this->pass($name[0]),
$name[1] => $this->pass($name[1]),
$name[2] => $this->pass($name[2]),
$name[3] => $this->pass($name[3]),
$name[4] => $this->pass($name[4]),
$name[5] => $this->pass($name[5]),
$name[6] => $this->pass($name[6]),
$name[7] => $this->pass($name[7]),
'official_image' => $image
);

$this->model->CreateOfficials($data);
}
}
