Models & Baking¶

In src/Model/Table folder create a new file called PostsTable.php with the following code:

<?php
namespace App\Model\Table;
use Cake\ORM\Table;

class PostsTable extends Table{
    public function initialize(array $config){
        $this->addBehavior('Timestamp');
    }
}

In PostsController.php remove the code from initialize and remove private $posts function and modify index function as follows:

<?php
public function index(){
    $posts = $this->Posts->find('all');
    $this->set(compact('posts'));
}

Now to get posts of certain $id change view function in PostsController to have the following code

In PostsController.php

<?php
public function view($id){
    $posts = $this->Posts->find('all');
    $post = $this->Posts->get($id);
    $this->set(compact('posts', 'post'));
}

In View.ctp

<div class = "row">
    <div class="columns large-3 medium-4">
        <h3>sidebar</h3>
    </div>
    <div class="columns large-9 medium-8">
        <h1><?= $post['title'] ?></h1>
        <p><?= $post['body'] ?></p>
    </div>
</div>

To sort the results so the newest posts will be on top modify the index function as follows:

<?php
public function index(){
    $posts = $this->Posts->find('all', array('order' => array('created' => 'desc')));
    $this->set(compact('posts'));
}

To create a new post do the following:

PostsController.php add the following code:

<?php
public function initialize(){
    parent::initialize();
        $this->loadComponent('Flash');
    }
    public function create(){
        $post = $this->Posts->newEntity();

    if($this->request->is('post')){
        $post = $this->Posts->patchEntity($post, $this->request->data);
        if($this->Posts->save($post)){
            $this->Flash->success(__('Post Created'));
            return $this->redirect(['action' => 'index']);
        }
        $this->Flash->error(__('Unable to save post'));
    }
    $this->set('post', $post);
}

To add timestamp to each post add the following to Template/Posts/index.ctp after the title tag:

<?php
<small><strong><?= $post['created']->format(DATE_RFC850); ?></strong></small>

Validation¶

To Add validation add the following code in the src/Model/PostsTable.php

<?php
namespace App\Model\Table;
use Cake\ORM\Table;
use Cake\Validation\Validator;

class PostsTable extends Table{
    public function initialize(array $config){
        $this->addBehavior('Timestamp');
    }
    public function validationDefault(Validator $validator){
        $validator
            ->notEmpty('title')
            ->RequirePresence('title')
            ->notEmpty('body')
            ->RequirePresence('body')
            ->notEmpty('author')
            ->RequirePresence('author')
            ->notEmpty('category')
            ->RequirePresence('category');
        return $validator;
    }
}

Update¶

To update a post add the following code to PostsController.php

<?php
public function edit($id){
    //die('create post');
    //$posts = $this->Posts->find('all');
    //$this->set(compact('posts'));

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

    if($this->request->is(['post', 'put'])){
        $this->Posts->patchEntity($post, $this->request->data);
        if($this->Posts->save($post)){
            $this->Flash->success(__('Post Updated'));
            return $this->redirect(['action' => 'index']);
        }
        $this->Flash->error(__('Unable to update post'));
    }
    $this->set('post', $post);
}

Create a new file under Layout/Posts called edit.ctp with the following code which is almost same as create.ctp

<?php
<h3>Edit Post</h3>
<?= $this->Form->create($Post); ?>
    <?= $this->Form->input('title', array(
                                'label' => 'Post Title',
                                'class' => 'class-name'
                        )); ?>
    <?= $this->Form->input('body', array(
                                'label' => 'Post Body',
                                'type' => 'textarea',
                                'escape' => false,
                                'class' => 'class-name'
                        )); ?>
    <?= $this->Form->input('category', array(
                                'label' => 'Categoty',
                                'type' => 'select',
                                'empty' => 'Select One',
                                'options' => ['Web Development', 'Design', 'Marketing'],
                                'class' => 'class-name'
                        )); ?>
    <?= $this->Form->input('author', array(
                                'label' => 'Author',
                                'class' => 'class-name'
                        )); ?>
    <?= $this->Form->input('time', [
        'type' => 'time',
        'interval' => 15
    ]); ?>
    <?= $this->Form->inputs([
        'name' => ['label' => 'Name', 'class' => 'class-name'],
        'age' => ['label' => 'Age', 'class' => 'class-name']
    ]); ?>
    <hr>
    <?= $this->Form->submit('Submit', array('class' => 'class-name')); ?>
<?= $this->Form->end(); ?>

Now edit Layout/Posts/view.ctp to have the following code:

<?php
<div class = "row">
<div class="columns large-3 medium-4">
    <h3>sidebar</h3>
</div>
<div class="columns large-9 medium-8">
   <h1><?= $post['title'] ?></h1>
   <p><?= $post['body'] ?></p>
</div>

<?= $this->Html->link('Edit Post', ['action' => 'edit', $post['id']], ['class' => 'class-name']); ?>

Delete¶

In PostsController.php add the following code:

<?php
public function delete($id){
    $this->request->allowMethod(['post', 'delete']);
    $post = $this->Posts->get($id);
    if($this->Posts->delete($post)){
        $this->Flash->success(__('Post Deleted'));
        return $this->redirect(['action' => 'index']);
    }
}

Now in Layout/Posts/view.ctp add the following code:

<?= $this->Form->postLink('delete',
                        ['action' => 'delete', $post['id']],
                        ['confirm' => 'Are you sure?','class' => 'className']); ?>
