KOstache
KOstache is a kohana module for using Mustache templates in your application.
Mustache is a logic-less template class. It is impossible to embed logic into mustache files.
Usage & Simple Example
View classes go in classes/view/
classes/view/example.php
<?php
class View_Example extends Kostache
{
public $foo = 'bar';
}
Template files go in templates/
templates/example.mustache
This is a {{foo}}
In your controller, just do:
$view = new View_Example;
echo $view;
And you get:
"This is a bar"
Complex Example
Model (This example uses AutoModeler):
<?php
class Model_Test extends AutoModeler
{
protected $_table_name = 'tests';
protected $_data = array(
'id' => '',
'name' => '',
'value' => '',
);
protected $_rules = array(
'name' => array('not_empty'),
'value' => array('not_empty'),
);
}
View:
<?php
class View_Example extends Kostache
{
public $title = 'Testing';
public function things()
{
return Inflector::plural(get_class(new Model_Test));
}
public function tests()
{
$tests = array();
foreach (AutoModeler::factory('test')->fetch_all() as $test)
{
$tests[] = $test->as_array();
}
return $tests;
}
}
Template:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>{{title}}</title>
</head>
<body>
<h1>{{title}}</h1>
<p>Here are all my {{things}}:</p>
<ul>
{{#tests}}
<li><strong>{{id}}:</strong> ({{name}}:{{value}})</li>
{{/tests}}
</ul>
</body>
</html>
Controller:
<?php
class Controller_Welcome extends Controller {
public function action_index()
{
echo new View_Example;
}
} // End Welcome
Grabbing a single model value
Model (This example uses AutoModeler):
<?php
class Model_Test extends AutoModeler
{
protected $_table_name = 'tests';
protected $_data = array(
'id' => '',
'name' => '',
'value' => '',
);
protected $_rules = array(
'name' => array('not_empty'),
'value' => array('not_empty'),
);
}
View:
<?php
class View_Singular extends Kostache
{
protected $_pragmas = array(Kostache::PRAGMA_DOT_NOTATION => TRUE);
public $thing_id = NULL;
public $title = 'Testing';
public function thing()
{
return new Model_Test($this->thing_id);
}
}
Template:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>{{title}}</title>
</head>
<body>
<h1>{{title}}</h1>
<p>This is just one thing:</p>
<h2>{{thing.id}}</h2>
<ul>
<li>Name: {{thing.name}}</li>
<li>Value: {{thing.value}}</li>
</ul>
</body>
</html>
Controller:
<?php defined('SYSPATH') or die('No direct script access.');
class Controller_Welcome extends Controller {
public function action_singular($id)
{
$view = new View_Singular;
$view->thing_id = $id;
echo $view;
}
} // End Welcome
Using the View_Layout class
KOstache comes with a View_Layout class instead of a template controller. This allows your layouts to be more OOP and self contained, and they do not rely on your controllers so much.
To use it, have your view extend the View_Layout class. You can then specify your own layout file by placing it in templates/layout.mustache. At a minimum, it needs to have a {{>body}} partial defined in it.
