Message: Call to undefined method Nsbh::post()
Filename: application\controllers\nsbh.php
Line Number: 25
nsbh.php
<?php
Class Nsbh extends CI_Controller{
var $API ="";
function __construct() {
parent::__construct();
$this->API="http://localhost/rest_ci/index.php";
$this->load->library('session');
$this->load->library('curl');
$this->load->helper('form');
$this->load->helper('url');
}
function index(){
$data['datansbh'] = json_decode($this->curl->simple_get($this->API.'/nsbh'));
$this->load->view('nsbh/list',$data);

$data = array(
'id' => $this->post('id'),
'name' => $this->post('name'),
'location' => $this->post('location'),

$insert = $this->curl->simple_post($this->API.'/nsbh', $data, array(CURLOPT_BUFFERSIZE => 10));
if($insert)

$this->session->set_flashdata('hasil','Insert Succeed');
}else
{
$this->session->set_flashdata('hasil','Insert Failed');

if($update)
{
$this->session->set_flashdata('hasil','Update Succeed');
}else
{
$this->session->set_flashdata('hasil','Update Failed');
}
redirect('nsbh');
}else{
$params = array('id'=> $this->uri->segment(3));
$data['datansbh'] = json_decode($this->curl->simple_get($this->API.'/nsbh',$params));
$this->load->view('nsbh/edit',$data);
}
}
function delete($id){
if(empty($id)){
redirect('nsbh');
}else{
$delete = $this->curl->simple_delete($this->API.'/nsbh', array('id'=>$id), array(CURLOPT_BUFFERSIZE => 10));
if($delete)
{
$this->session->set_flashdata('hasil','Deleted');
}else
{
$this->session->set_flashdata('hasil','Failed');
}
redirect('nsbh');
}
}
}
And this is what's on line 25
'id'=> $this->post('id'),

Answer 1

You are missing input in 'id' => $this->post('id')
So, the right code is as follow:
'id' => $this->input->post('id')
You have to use input on all other places also.

Answer 2

change from
$data = array( 'id' => $this->post('id'),
'name' => $this->post('name'),
'location' => $this->post('location'),
'tgl' => $this->post('tgl'),
'addrs' => $this->post('addrs'));
to
$data = array('id' => $this->input->post('id'),
'name' => $this->input->post('name'),
'location' => $this->input->post('location'),
'tgl' => $this->input->post('tgl'),
'addrs' => $this->input->post('addrs'));
As you already did in edit function

Answer 3

In the constructor add $this->load->library('form_validation');
So your constructor looks like this:
function __construct() {
parent::__construct();
$this->API="http://localhost/rest_ci/index.php";
$this->load->helper('form');
$this->load->helper('url');
$this->load->library('session');
$this->load->library('curl');
$this->load->library('form_validation');
}
