<?php echo $this->session->flashdata('srr')?>

<div id="frm">

<form action="<?php echo site_url('site/insert')?>" method="POST">

<fieldset>

<legend>Tambah Data</legend>

<label>Nama Awal</label>

<input type="text" name="nama_awal" placeholder="Enter Your First Name" required/>

<label>Nama Akhir</label>

<input type="text" name="nama_akhir" placeholder="Enter Your Last Name" />

<label>Alamat</label>

<textarea name="alamat" ></textarea>

<input type="submit" value="SAVE" name="add"/>

public function insert()

{

$nama_awal=$this->input->post('nama_awal',true);

$nama_akhir=$this->input->post('nama_akhir',true);

$alamat=$this->input->post('alamat',true);

$object=array(

'nama_awal'=>$nama_awal,      //nama field database

'nama_akhir'=>$nama_akhir, //nama field database

'alamat'=>$alamat //nama field database

);

$this->db->insert('tbsiswa',$object);

$this->load->view('welcome_message');

$this->session->set_flashdata('srr',"Data Berhasil di input");
