README

An Active Record like pattern for template rendering with PHP.

• Define and retrieve variables
• Accessor and mutator functions
• Render in any engine
• Built in support for Twig, Smarty, Plates and Dwoo

Installation

Install Spin via composer. Then extend Spin\Template\Template.

composer require spin/template

Example

class Homepage extends Spin\Template\Template
{
	/**
	 * The template file
	 */
	protected $file = 'templates/home.php';

	/**
	 * Convert the first character of first name to uppercase on retrieval
	 */
    public function getFirstNameAttribute($value)
    {
        return ucfirst($value);
    }

	/**
	 * Convert the whole string to lowercase when setting first name
	 */
    public function setFirstNameAttribute($value)
    {
        $this->attributes['first_name'] = strtolower($value);
    }

	/**
	 * Convert the unix timestamp to a human friendly date on retrieval
	 */
	public function getDateAttribute($value)
	{
		return date('Y-m-d', $value);
	}
}

$template = new Homepage();

// Assign variables as properties
$template->first_name = 'john';
$template->date = time();

// You can also assign variables as an array
$template['weather'] = 'frightful';

// Render the template
echo $template->render();

templates/home.php:

Hello <?php echo $first_name; ?> today's date is <?php echo $date; ?>. The weather outside is <?php echo $weather; ?>

Output:

Hello John today's date is 2015-08-05. The weather outside is frightful.

As you can see we assign variables to our class either via properties or array syntax and call the render() method, which passes those variables to our template defined in $file and return's the rendered template.

Accessors and mutators

Accessors and mutators allow you to format template variables when retrieving them for rendering or setting their value.

If you have ever used Eloquent mutators for getting/setting data on an object it's the same concept (in fact it's almost the same code - thanks Laravel).

To define an accessor, create a getFooAttribute method in your class where Foo is the camel cased name of the variable you wish to access. See the getFirstNameAttribute method in the example above.

To define a mutator, create a setFooAttribute method in your class where Foo is the camel cased name of the variable you wish to change. See the setFirstNameAttribute method in the example above.

Rendering engine

To use a different rendering engine pass an object that implements Spin\Template\Engine\EngineInterface to the setEngine method.

Support for Twig, Smarty, Plates and Dwoo are already included and can be implemented as per the examples below:

Twig

class Homepage extends Spin\Template\Template
{
	protected $file = 'home.twig';

	public function __construct()
	{
		$loader = new Twig_Loader_Filesystem('/path/to/templates');
		$twig = new Twig_Environment($loader);

		$this->setEngine(new Spin\Template\Engine\TwigEngine($twig));
	}
}

Smarty

class Homepage extends Spin\Template\Template
{
	protected $file = 'home.smarty';

	public function __construct()
	{
		$smarty = new Smarty();
		$smarty->setTemplateDir('/path/to/templates');
		$smarty->setCompileDir('/path/to/templates_c');

		$this->setEngine(new Spin\Template\Engine\SmartyEngine($smarty));
	}
}

Plates

class Homepage extends Spin\Template\Template
{
	protected $file = 'home';

	public function __construct()
	{
		$plates = new League\Plates\Engine('/path/to/templates');

		$this->setEngine(new Spin\Template\Engine\PlatesEngine($plates));
	}
}

Dwoo

class Homepage extends Spin\Template\Template
{
	protected $file = 'home.dwoo';

	public function __construct()
	{
		$dwoo = new Dwoo\Core();
		$dwoo->setTemplateDir('/path/to/templates');
		$dwoo->setCompileDir('/path/to/templates_c');

		$this->setEngine(new Spin\Template\Engine\DwooEngine($dwoo));
	}
}
