ThinkPHP is a PHP framework based on the MVC development model, used for the development of fast, scalable and easy-to-maintain web applications. In this article, we will learn how to use the power of the ThinkPHP framework to implement simple article editing functions in a web application.

We will create a module called "Article", which will contain the functions of creating, editing and deleting articles. We will start with the database and create a new data table "articles" which will store various properties of the articles such as title, content and status.

First, we need to create a database with a random name. Within this database, we will create a new table named "articles". This table will have the following columns:

id – This is a unique identifier for each article, it will be an integer, primary key and auto-incrementing.

title – This is the title of the article, it will be a string, up to 50 characters.

body – This is the main body of the article, it will be one large text.

status – This is the status of the article, it will be a boolean value.

created_at – This is the date timestamp when the article was created, it will be an integer.

updated_at – This is the date timestamp when the article was last updated, it will be an integer.

Next, in our project we will create a module called "Article", we can create a new module by using the following command in the terminal:

php think module Article

This will create a module called "Article" in our project. This module will contain the following controllers: Index, Create, Edit, Delete and Update. We will define the Articles table in the model of "Article" and implement the article list in the Index controller of "Article".

In our model, we need to use ThinkPHP ORM to define the Articles table. We can add the following code to the model file in order to define the Articles table:

namespace app\article\model;

use think\Model;

class Articles extends Model
{

// 數(shù)據(jù)表名
protected $table = &#39;articles&#39;;

// 主鍵名
protected $pk = &#39;id&#39;;

// 字段定義
protected $schema = [
    &#39;id&#39;           =>?'int',
????'title'????????=>?'string',
????'body'?????????=>?'text',
????'status'???????=>?'boolean',
????'created_at'???=>?'int',
????'updated_at'???=>?'int',
];</p>
<p>}</p>
<p>Next, in our Index controller, we will use the ORM to get all the articles and pass them to displayed in the view. To achieve this we will use the following code: </p>
<p><?php<br/>namespace app\article\controller;</p><p>use app\article\model\Articles;</p><p>class Index<br/>{</p><pre class="brush:php;toolbar:false">public function index()
{
    // 獲取所有文章
    $articles = Articles::select();

    // 渲染視圖
    return view(&#39;index&#39;, [
        &#39;articles&#39; =>?$articles,
????]);
}</p>
<p>}</p>
<p>In our view we will display the title and creation date of all articles and provide a link for users to edit and delete articles . The view file is as follows: </p>
<p><!DOCTYPE html><br><html><br><head></p>
<pre class="brush:php;toolbar:false"><title>文章列表</title>

Article list

Title	Creation Date	Action
title; ?>	created_at); ?>	$article->id]); ?>">Edit $article->id]); ?>">Delete

">創(chuàng)建文章

在我們的“Article”的Create控制器中，我們將顯示一個(gè)表單，以供用戶創(chuàng)建新的文章。表單將包含標(biāo)題和主體字段，以及submit按鈕。我們將使用以下代碼來實(shí)現(xiàn)：

namespace app\article\controller;

use app\article\model\Articles;
use think\Request;

class Create
{

public function index()
{
    // 渲染視圖
    return view(&#39;create&#39;);
}

public function create(Request $request)
{
    // 獲取表單數(shù)據(jù)
    $title = $request->param('title');
????$body?=?$request->param('body');

????//?創(chuàng)建新文章
????$article?=?new?Articles();
????$article->title?=?$title;
????$article->body?=?$body;
????$article->status?=?true;
????$article->created_at?=?time();
????$article->updated_at?=?time();
????$article->save();

????//?跳轉(zhuǎn)到文章列表頁面
????return?redirect('/article/index');
}</p>
<p>}</p>
<p>我們的Create控制器中有兩個(gè)方法：index和create。index方法將渲染我們的表單視圖，create方法將獲取表單數(shù)據(jù)并在數(shù)據(jù)庫中創(chuàng)建新的文章。</p>
<p>我們的表單視圖將包含一個(gè)<form>標(biāo)記，其中包含“標(biāo)題”和“主體”輸入字段，以及submit按鈕。表單視圖如下所示：</p>
<p><!DOCTYPE html><br><html><br><head></p>
<pre class="brush:php;toolbar:false"><title>創(chuàng)建文章</title>

創(chuàng)建文章

<label for="title">標(biāo)題</label>
<input type="text" name="title" id="title">

<label for="body">主體</label>
<textarea name="body" id="body"></textarea>

<button type="submit">創(chuàng)建</button>

在我們的“Article”的Edit控制器中，我們將顯示與Create視圖相似的表單，但是表單將包含當(dāng)前文章的標(biāo)題和主體字段。我們將使用以下代碼實(shí)現(xiàn)：

namespace app\article\controller;

use app\article\model\Articles;
use think\Request;

class Edit
{

public function index(Request $request)
{
    // 獲取文章ID
    $id = $request->param('id');

????//?獲取文章
????$article?=?Articles::find($id);

????//?渲染視圖
????return?view('edit',?[
????????'article'?=>?$article,
????]);
}

public?function?update(Request?$request)
{
????//?獲取表單數(shù)據(jù)
????$id?=?$request->param('id');
????$title?=?$request->param('title');
????$body?=?$request->param('body');

????//?更新文章
????$article?=?Articles::find($id);
????$article->title?=?$title;
????$article->body?=?$body;
????$article->updated_at?=?time();
????$article->save();

????//?跳轉(zhuǎn)到文章列表頁面
????return?redirect('/article/index');
}</p>
<p>}</p>
<p>我們的Edit控制器中也有兩個(gè)方法：index和update。index方法將獲取當(dāng)前文章的數(shù)據(jù)，并渲染我們的表單視圖。update方法將獲取表單數(shù)據(jù)并更新文章。</p>
<p>我們的表單視圖將包含一個(gè)<form>標(biāo)記，其中包含輸入字段，以供用戶編輯當(dāng)前文章的標(biāo)題和主體。表單視圖顯示如下：</p>
<p><!DOCTYPE html><br><html><br><head></p>
<pre class="brush:php;toolbar:false"><title>編輯文章</title>

編輯文章

<input type="hidden" name="id" value="<?php echo $article->id;??>">

<label for="title">標(biāo)題</label>
<input type="text" name="title" id="title" value="<?php echo $article->title;??>">

<label for="body">主體</label>
<textarea name="body" id="body"><?php echo $article->body;??></textarea>

<button type="submit">更新</button>

在我們的“Article”的Delete控制器中，我們將刪除當(dāng)前文章。我們將使用以下代碼實(shí)現(xiàn)：

namespace app\article\controller;

use app\article\model\Articles;
use think\Request;

class Delete
{

public function index(Request $request)
{
    // 獲取文章ID
    $id = $request->param('id');

????//?刪除文章
????Articles::destroy($id);

????//?跳轉(zhuǎn)到文章列表頁面
????return?redirect('/article/index');
}
}
我們的Delete控制器中只有一個(gè)方法：index。這個(gè)方法將獲取當(dāng)前文章的ID，并從數(shù)據(jù)庫中刪除它。然后，它將重定向到文章列表頁面。
現(xiàn)在我們已經(jīng)完成了我們的“Article”模塊。我們可以在我們的應(yīng)用程序中使用以下URL訪問它：
/article/index – 文章列表
/article/create – 創(chuàng)建文章
/article/edit/id – 編輯文章
/article/delete/id – 刪除文章
我們已經(jīng)成功地使用ThinkPHP框架創(chuàng)建了一個(gè)簡單的文章編輯應(yīng)用程序?，F(xiàn)在，我們可以使用這些知識(shí)來創(chuàng)建更復(fù)雜的Web應(yīng)用程序。
