====== CakePHP ======
===== Usage (after install) =====
The examples below are from a working cakeblog tutorial: http://manual.cakephp.org/appendix/blog_tutorial
==== Create Models for Database Tables ====
  * singlar: post.php in app/models/ for database table posts
  * example:<code php>
<?php

class Post extends AppModel
{
    var $name = 'Post';

	var $validate = array(
		
		'title' => VALID_NOT_EMPTY,
		'body'	=> VALID_NOT_EMPTY
		
	);
}

?>
</code>

==== Create Controllers for Models ====
  * plural: posts_controller.php in app/controllers for model post.php
  * functions created here are locations the user can visit
  * example:<code php>
<?php

class PostsController extends AppController
{
    var $name = 'Posts';

    function index()
    {
        $this->set('posts', $this->Post->findAll());
    }

    function view($id = null)
    {
        $this->Post->id = $id;
        $this->set('post', $this->Post->read());
    }

	function add()
	{
		if(!empty($this->data))
		{
			if($this->Post->save($this->data))
			{
				$this->flash('Your post has been saved.','/posts');
			}
		}
	}
	
	function delete($id)
	{
		$this->Post->del($id);
		$this->flash('The post with id: '.$id.' has been deleted.', '/posts');
	}
	
	function edit($id = null)
	{
		if(empty($this->data))
		{
			$this->Post->id = $id;
			$this->data = $this->Post->read();
		}
		else
		{
			if($this->Post->save($this->data['Post']))
			{
				$this->flash('Your post has been updated.','/posts');
			}
		}
		
	}
}

?>

</code>


==== Create Views ====
  * create a folder in app/views as a plural of model: app/views/**posts**
  * create views for each function in posts_controller.php
  * files have exact name as function, with a .thtml extension
  * examples:<code php>
// add.thtml
<h1>Add Post</h1>
<form method="post" action="<?php echo $html->url('/posts/add')?>">
	<p>
		Title:
		<?php echo $html->input('Post/title', array('size' => '40'))?>
		<?php echo $html->tagErrorMsg('Post/title', 'Title is requried.')?>
	</p>
	<p>
		Body:
		<?php echo $html->textarea('Post/body', array('rows'=>'10')) ?>
		<?php echo $html->tagErrorMsg('Post/body', 'Body is required.') ?>
	</p>
	<p>
		<?php echo $html->submit('Save') ?>
	</p>
</form>

// edit.thtml
<h1>Edit Post</h1>
<form method="post" action="<?php echo $html->url('/posts/edit')?>">
	<?php echo $html->hidden('Post/id'); ?>
	<p>
		Title:
		<?php echo $html->input('Post/title', array('size' => '40'))?>
		<?php echo $html->tagErrorMsg('Post/title', 'Title is requried.')?>
	</p>
	<p>
		Body:
		<?php echo $html->textarea('Post/body', array('rows'=>'10')) ?>
		<?php echo $html->tagErrorMsg('Post/body', 'Body is required.') ?>
	</p>
	<p>
		<?php echo $html->submit('Save') ?>
	</p>
</form>

// index.thtml
<h1>Blog posts</h1>
<p><?php echo $html->link("Add Post", "/posts/add") ?></p>
<table>
    <tr>
        <th>Id</th>
        <th>Title</th>
        <th>Created</th>
    </tr>

    <?php foreach ($posts as $post): ?>
    <tr>
        <td><?php echo $post['Post']['id']; ?>
			<?php echo $html->link(
				'Delete',
				"/posts/delete/{$post['Post']['id']}",
				null,
				'Are you sure?'
			)?>
			<?php echo $html->link('Edit', "/posts/edit/".$post['Post']['id']); ?>
		</td>
        <td>
            <?php echo $html->link($post['Post']['title'], "/posts/view/".$post['Post']['id']); ?>

        </td>
        <td><?php echo $post['Post']['created']; ?></td>
    </tr>
    <?php endforeach; ?>

</table>

// view.thtml
<h1><?php echo $post['Post']['title']?></h1>

<p><small>Created: <?php echo $post['Post']['created']?></small></p>

<p><?php echo $post['Post']['body']?></p>
