遇到未捕获的异常，调用未定义的方法

Question

我遇到了这个错误，并一直试图弄清楚连续 3 天出了什么问题，但没有运气：

遇到未捕获的异常

类型：错误

消息：调用未定义的方法 Nsbh：:p ost((

文件名： 应用程序\控制器sbh.php

行号：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);
}

function create(){
if(isset($_POST['submit'])){
$data = array(
'id'           => $this->post('id'),
'name'          => $this->post('name'),
'location'    => $this->post('location'),
'tgl'    => $this->post('tgl'),
'addrs'    => $this->post('addrs'));
$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');
}
redirect('nsbh');
}else{
$this->load->view('nsbh/create');
}
}

function edit(){
if(isset($_POST['submit'])){
$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'));
$update =  $this->curl->simple_put($this->API.'/nsbh', $data, array(CURLOPT_BUFFERSIZE => 10)); 
if($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');
}
}
}

这就是第 25 行的内容

'id'=> $this->post('id'),

Answer 1

你在'id' => $this->post('id'(中缺少输入

因此，正确的代码如下：

'id' => $this->input->post('id')

您还必须在所有其他地方使用输入。

Answer 2

更改自

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

自

$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'));

正如您在编辑功能中所做的那样

Answer 3

在构造函数中添加$this->load->library('form_validation');

所以你的构造函数看起来像这样：

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');
}
