Ссылка на урок: https://www.youtube.com/watch?v=pCB5ShwtHdw&t=472s

Укажем нашу БД: config/app.php

Строки 'Datasources' => [
'default'

src/Controller создаем файл PostsController.php

Пишем:

<?php

namespace App\Controller;

use App\Controller\AppController;

class PostsController extends AppController {

public function index() {

}

}

В src/Template создаем папку Posts и в ней файл index.ctp

В config/routs.php меняем

$routes->connect('/', ['controller' => 'Posts', 'action' => 'index', 'home']);

Идем на страницу: http://bootswatch.com/paper/#navbar

И скачиваем там код навигационном панели.

Далее в src/Tamplate/Layout/default.ctp вставляем эту навигационную панель.

Также подключим свои стили:

<?php echo $this->Html->css('bootstrap.css') ?>
<?php echo $this->Html->script('jquery-3.2.1') ?>
<?php echo $this->Html->script('bootstrap.css') ?>

Далее в src/Template/Posts/index.ctp вставим код таблицы с сайта: http://bootswatch.com/paper/#tables

<div class="row"></div>

<table class="table table-striped table-hover ">

<thead>

<tr>

<th>Title</th>

<th>Descripion</th>

<th>Action</th>

</tr>

</thead>

<tbody>

<tr>

<td>Column content</td>

<td>Column content</td>

<td>Column content</td>

</tr>

</tbody>

</table>

</div>

Идем в PostsController.php и пишем там:

public function index() {

$this->set('posts', $this->Posts->find('all'));

}

Далее в src/Template/Posts/index.ctp вставим код:

<div class="row"></div>

<h2>View all Posts</h2>

<?php echo $this->Html->link('ADD POST', ['action' => 'add'], ['class' => 'btn btn-primary']); ?>

<table class="table table-striped table-hover ">

<thead>

<tr>

<th>Title</th>

<th>Descripion</th>

<th>Action</th>

</tr>

</thead>

<tbody>

<?php if(!empty($posts)) : ?>

<?php foreach($posts as $post) : ?>

<tr>

<td><?php echo $post->title; ?></td>

<td><?php echo $post->description; ?></td>

<td></td>

</tr>

<?php endforeach; ?>

<?php else: ?>

<td>No record found</td>

<?php endif; ?>

</tbody>

</table>

</div>

Мы добавили кнопку для добавления статьи.

Идем в PostsController.php и пишем там:

public function add() {

}

В src/Template/Posts создадим файл add.ctp

С сайта http://bootswatch.com/paper/#forms копируем форму.

<fieldset>

<legend>Add Post</legend>

<div class="form-group">

<div class="col-lg-10">

<?php echo $this->Form->input('title', ['class' => 'form-control', 'Placeholder' => 'Title']); ?>

</div>

</div>

<div class="form-group">

<div class="col-lg-10">

<?php echo $this->Form->input('description', ['class' => 'form-control', 'Placeholder' => 'Description']); ?>

</div>

</div>

<div class="form-group">

<div class="col-lg-10 col-lg-offset-2">

<?php echo $this->Form->button(__('Add New Post'), ['class' => 'btn btn-primary']); ?>

<?php echo $this->Html->link('Back', ['action' => 'index'], ['class' => 'btn btn-default']); ?>

</div>

</div>

</fieldset>

Идем в PostsController.php и пишем там:

public function add() {

$post = $this->Posts->newEntity();

if($this->request->is('post')) {

// валидация

// https://book.cakephp.org/3.0/en/orm/saving-data.html#validation-and-patchentity

$post = $this->Posts->patchEntity($post, $this->request->getData());

if($this->Posts->save($post)) {

$this->Flash->success('Post added successfully', ['key' => 'message']);

return $this->redirect(['action' => 'index']);

}

$this->Flash->error(__('Unable to add your post'));

}

$this->set('post', $post);

}

В add.ctp открываем и закрываем форму:

<?php echo $this->Form->create($post); ?>

<fieldset>

<legend>Add Post</legend>

<div class="form-group">

<div class="col-lg-10">

<?php echo $this->Form->input('title', ['class' => 'form-control', 'Placeholder' => 'Title']); ?>

</div>

</div>

<div class="form-group">

<div class="col-lg-10">

<?php echo $this->Form->input('description', ['class' => 'form-control', 'Placeholder' => 'Description']); ?>

</div>

</div>

<div class="form-group">

<div class="col-lg-10 col-lg-offset-2">

<?php echo $this->Form->button(__('Add New Post'), ['class' => 'btn btn-primary']); ?>

<?php echo $this->Html->link('Back', ['action' => 'index'], ['class' => 'btn btn-default']); ?>

</div>

</div>

</fieldset>

<?php echo $this->Form->end(); ?>

В index.ctp добавляем флешку:

<?php echo $this->Flash->render('message'); ?>

Делаем просмотр и удаление статьи:

<div class="row"></div>

<?php echo $this->Flash->render('message'); ?>

<h2>View all Posts</h2>

<?php echo $this->Html->link('ADD POST', ['action' => 'add'], ['class' => 'btn btn-primary']); ?>

<table class="table table-striped table-hover ">

<thead>

<tr>

<th>Title</th>

<th>Descripion</th>

<th>Action</th>

</tr>

</thead>

<tbody>

<?php if(!empty($posts)) : ?>

<?php foreach($posts as $post) : ?>

<tr>

<td><?php echo $post->title; ?></td>

<td><?php echo $post->description; ?></td>

<td>

<?php echo $this->html->link('View', ['action' => 'view', $post->id], ['class' => 'btn btn-primary'])?>

<?php echo $this->html->link('Edit', ['action' => 'edit', $post->id], ['class' => 'btn btn-success'])?>

<?php

echo $this->Form->postlink(

'Delete',

['action' => 'delete', $post->id],

['class' => 'btn btn-danger'],

['confirm' => 'Are you sure to delete?']

)

?>

</td>

</tr>

<?php endforeach; ?>

<?php else: ?>

<td>No record found</td>

<?php endif; ?>

</tbody>

</table>

</div>

Идем в PostsController.php и пишем там:

public function view($id = null) {

$posts = $this->Posts->get($id); // вибираем по id

$this->set('post', $posts);

}

Создаем файл view.ctp

<p><?php echo $post->title; ?></p>

<p><?php echo $post->description; ?></p>

<?php echo $this->html->link('Back', ['action' => 'index'], ['class' => 'btn btn-primary']); ?>

Идем в PostsController.php и пишем там:

public function edit($id = null) {

$post = $this->Posts->get($id);

if ($this->request->is(['post', 'put'])) {

$this->Posts->patchEntity($post, $this->request->getData());

if ($this->Posts->save($post)) {

$this->Flash->success(__('Ваша статья была обновлена.'));

return $this->redirect(['action' => 'index']);

}

$this->Flash->error(__('Ошибка обновления вашей статьи.'));

}

$this->set('post', $post);

}

Создаем файл edit.ctp

<?php echo $this->Form->create($post); ?>

<fieldset>

<legend>Add Post</legend>

<div class="form-group">

<div class="col-lg-10">

<?php echo $this->Form->input('title', ['class' => 'form-control', 'Placeholder' => 'Title']); ?>

</div>

</div>

<div class="form-group">

<div class="col-lg-10">

<?php echo $this->Form->input('description', ['class' => 'form-control', 'Placeholder' => 'Description']); ?>

</div>

</div>

<div class="form-group">

<div class="col-lg-10 col-lg-offset-2">

<?php echo $this->Form->button(__('Add New Post'), ['class' => 'btn btn-primary']); ?>

<?php echo $this->Html->link('Back', ['action' => 'index'], ['class' => 'btn btn-default']); ?>

</div>

</div>

</fieldset>

<?php echo $this->Form->end(); ?>

Идем в PostsController.php и пишем там:

public function delete($id = null) {

$this->request->allowMethod(['post', 'delete']);

$post = $this->Posts->get($id);

if($this->Posts->delete($post)) {

$this->Flash->success('Post deleted successfully', ['key' => 'message']);

return $this->redirect(['action' => 'index']);

}
