Codeigniter - 显示和编辑记录的最后一个 ID答案

【问题标题】：Codeigniter - Show and Edit Last Id recordedCodeigniter - 显示和编辑记录的最后一个 ID
【发布时间】：2019-01-05 03:32:22
【问题描述】：

我想在包页面上根据 packageId 显示最后插入数据。例如，我编辑金包后，系统添加了金包的新数据，并在包页面上显示最后插入的金包。但是我根据 packageId 列出数据，如何根据 packageId 列出它们？如何再次编辑黄金包的最后插入 ID？

控制器包：

<?php

class Package extends CI_Controller {

    public function __construct()

    {

        parent::__construct();

        $this->load->model('service_model');

    }

    public function index()
    {

        $this->lang->load('content', $this->session->userdata('userLang'));

        $viewData['packs'] = $this->db->get("package")->result();

        $this->load->view('package', $viewData);
    }

    public function edit($packageId)
    {

        $this->lang->load('content', $this->session->userdata('userLang'));

        $viewData['packages'] = $this->db->where("packageId", $packageId)->get("package")->result();

        $viewData['packs'] = $this->db->get("package")->result();

        $this->load->view('package_edit', $viewData);

    public function update($packageId) {



        $this->lang->load('content', $this->session->userdata('people_lang'));

        $viewData['services'] = $this->service_model->update_services($packageId);

        $this->load->view('package',$viewData);

            $data = array (

                "packageEditUser" => $this->input->post("packageEditUser"),

            }else {

                echo "Hata!";

            }

    }

【问题讨论】：

如果您在每个视图中显示一条记录，那么您应该使用row(); 而不是result() 从表中获取记录
我想显示包的更新数据。但是当更新时我添加了新的插入，我想显示包的最后插入数据。如何显示最后一个插入 ID？
在插入完成后使用$this->db->insert_id();获取插入ID，我不知道你在你的代码中使用了什么逻辑，但是在更新任何记录时使用带有where子句的更新查询而不是插入查询跨度>
如何在这个项目中使用它？你能给出答案吗？
我有 3 个套餐，分别是 Silver、Gold 和 Platinum。我想编辑这些包首选项。例如，我想在更新包时添加新的黄金包列，如插入。我想显示最后一次黄金包编辑。

标签： php sql codeigniter count insert

【解决方案1】：

如果您不想在更新后丢失数据。您必须插入数据，例如没有更新的新数据，并且要选择必须使用时间的最新更新数据，请创建两个新列 update_id，current_time。像这样。

之后，如果您想显示最后更新的数据，请使用 Current_time 选择这样的

$this->db->order_by('Current_time','DESC');
$data = $this->db->get('comment_update',1)->result_array();

【讨论】：

当我想编辑包时如何编辑这个？例如，我编辑了 Gold Package。我想再次编辑它。如何在包视图中显示它？
这项工作类似于 StackOverflow 答案的编辑。
因此，在同一张表中，我创建了 packageRev Id。例如，当我编辑 Gold 包时 - 它有 packageId 1- 系统自动将 packageId 1 添加到 packageRev 1 并插入新的内容。我是这样想的。可能吗？我添加到我的数据库中。
你能给我看一下包裹视图吗？如何调用包视图上的新编辑？
是的。您想在视图中看到什么？最后更新的数据还是最后插入的数据？
