我正在尝试在codeigniter中构建一个支持ajax的购物车,现在我遇到了如何将响应作为HTML进行编码并将其编码为JSON响应的问题,然后在购物车页面附加响应.
这是javascript代码:
$('.addtocart').on('click', function (event) {
event.preventDefault();
var AddedQty = parseInt($('#attr-quantity').val());
$('#shoppingcart div.cart, #shoppingcart div.loading').remove();
$('#shoppingcart').append('<div class="loading"></div>');
shoppingcart.open();
$.post('/mywebsite/cart/add', {
itemId: $('.addtocart').data('itemId'),
quantity: AddedQty
}, function (response) {
var html = $(response.ShoppingCartHtml).html();
shoppingcart.update(html);
shoppingcart.close();
});
});
这是购物车控制器的代码:
public function add() {
$this->load->model('cart_model');
$id = $this->input->post('itemId');
$qty = $this->input->post('quantity');
$cart = $this->cart->contents();
$exists = false;
$rowid = '';
foreach ($cart as $item) {
if ($item['id'] == $id) {
$exists = true;
$rowid = $item['rowid'];
$qty = $item['qty'] + $qty;
}
} …我有最后一列的表是一个获取整个行数据的元素,
当我使用分页时,只有触发我的事件处理程序的第一页,第2 - 3 - 4页等等不会触发我的事件处理程序.
禁用分页时,所有记录都会触发我的事件处理程序.
下面是用于初始化的javascript和事件处理程序
var OTkaryawan = $('#table_karyawan').dataTable({ });
$(".select_row").click(function() {
// var row = $(this).closest('tr')[0];
// var aData = OTkaryawan.fnGetData(row);
// alert(aData[0]);
alert('A');
});
下面是我的表的html
<table id="table_karyawan" style="border: 1px #ccc solid;">
<thead>
<tr>
<th>NIK</th>
<th>Nama Lengkap</th>
<th>Lokasi Kerja</th>
<th>Departemen</th>
<th>Jabatan</th>
<th>Action</th>
</tr>
</thead>
<tbody>
<?php foreach ($master_karyawan as $key => $value): ?>
<tr>
<td><?= $value['nik']; ?></td>
<td><?= $value['nama']; ?></td>
<td><?= $value['lokasikerja']; ?></td>
<td><?= $value['departemen']; ?></td>
<td><?= $value['jabatan']; ?></td>
<td class="select_row">Select</td>
</tr>
<?php endforeach; ?>
</tbody> …我检查并重新检查了我的代码,引用了整个网络上的CI文档和其他帖子,但是我没有成功实现set_value()方法,以便在验证失败后重新填充表单字段.也许我错过了CI框架的一些非常重要的东西(我对它很新),但是你的见解会非常感激.
我的控制器方法中有以下内容:
public function form_step2(){
//Form Setup
$this->load->helper('form');
$this->load->helper('url');
$this->load->library('form_validation');
$data['title'] = $this->base_title;
$data['base_url'] = base_url();
//Validation Settings - must be set per step
$this->form_validation->set_rules('request_type', 'Request Type', 'required');
*...more of the same set_rules()*
if ($this->form_validation->run() === FALSE) {
### Validation failed or New Form
// Get form element data
$data['request_types'] = $this->my_model->get_form_data('request_type');
*...more of the same get_form_data() calls for loading form elements*
//Generate Page from View Templates
$this->load->view('templates/header', $data);
$this->load->view('templates/form_step2', $data);
$this->load->view('templates/footer');
} else {
### Save to database
$this->my_model->set_data($data); …我试图从亚马逊S3桶子文件夹中获取所有文件,并使其可以在网页中下载.
我有一个叫做图像的桶.在那个桶里面我有一些其他的文件夹.现在我试图获取该子文件夹中的所有文件并在页面中显示它.S3铲斗:/ images/images/test1// images/test2// images/test1/1/images/test1/2/images/test1/1/item
我试过这样,但无法得到预期的结果.
// Target files full path : images/test1/1/item
$bucketName = 'images';
$source = '/test1/1/item'
$image = $this->s3->getBucket($bucketName);
foreach ($image as $key=>$data){
$k = $data['name'];
print_r($k); // now this gives me full list of everything inside the images bucket.
}
现在,如果我想从存储桶中获取对象,我可以使用getObject,我尝试这样做:
$result = $this->s3->getObject($image); // I am confused about this one
任何建议将不胜感激.谢谢,
在使用Josue Ibarra的以下答案后,我得到了类似的东西

这是一个ajax(getjson)url的快照,其中"union"被添加为GET变量: 现在,如果你改变"union"这样的单词,就像"unsion"一样,我得到一个回复但是如果"union"这个词到位了,像"xxunionxx"一样可读,但仍然禁止回复.
我的网站运行在CI(CodeIgniter)框架上.我想知道我的服务器是否有过滤？

我在Ion Auth身份验证库中的一个真正的CodeIgniter项目中发生了这种情况,但为了清楚起见,我将其简化为最简单的形式.
我有这一行脚本位于http://localhost/~captbaritone/redirect/index.php:
<?php header("Refresh:0;url=https://google.com");¬
在我的浏览器中,它会重定向到Google.com.
为了测试它,我写了这个验收测试:
<?php
$I = new WebGuy($scenario);
$I->wantTo('Redirect to Google.com');
$I->amOnPage('/index.php');
$I->seeCurrentUrlEquals('https://www.google.com/');
我acceptance.suite.yml看起来像这样:
class_name: WebGuy
modules:
enabled:
- PhpBrowser
- WebHelper

<?php
Class category_model extends CI_Model {
var $table_name = 'category';
function get_all_categories()
{
$this->db->select('*');
$this->db->from($this->table_name);
return $this->db->get();
}
}
?>
然后在Codeigniter controller-folder中创建了一个category.php文件:
<?php
include(APPPATH.'libraries/REST_Controller.php');
class Category extends REST_Controller {
function __construct()
{
parent::__construct();
$this->load->model('category_model');
}
function category_get()
{
$data = $this->category_model->get_all_categories();
$this->response($data);
}
}
?>
现在,当我进入http://localhost/myproejcts/ci/index.php/category/category- 我得到错误{"status":false,"error":"Unknown method."}？
问题是什么？

对控制器类响应的最大LOC(LINE OF CODE)影响是否......这是重要的事情..
1.a)Controller: LOC 120, public functions exist 3.
b)Controller: LOC 120, public functions exist 3.
c)Controller: LOC 120, public functions exist 3.
2.) Controller LOC 720, pubic function 10.
it handle all the things in the same class.
哪一个更好？
