Aura.Html provides HTML escapers and helpers, including form input helpers, that can be used in any template, view, or presentation system.

In this post I would like to give you a short introduction to Aura.Html and how you could use with Plates a native php templating system like Aura.View.

Aura.Html was extracted from Aura.View helper functions of version 1, when we at aura noticed that people who uses Aura.Input may need some html helper functions and they may not be using a templating like Aura.View, but some other templating system.

You can see an example of a simple contact form with Aura.Input.

Installation

The easiest way to install Aura.Html is via composer. Let us create our composer.json

{ "require" : { "aura/html" : "2.*@dev" , "league/plates" : "2.*" } }

One of the good thing about Plates is you can create extensions.

Let us create an extension that can make use of Aura.Html helpers inside Plates. Any Plates extension should implement League\Plates\Extension\ExtensionInterface which contains a getFunctions method which returns the functions available within your templates.

We are going to name it as AuraHtmlExtension and call functions as aurahtml() or html() via the template.

<?php use League\Plates\Extension\ExtensionInterface ; use Aura\Html\HelperLocator ; class AuraHtmlExtension implements ExtensionInterface { public $engine; public $template; protected $helper; public function __construct( HelperLocator $helper) { $this -> helper = $helper; } public function getFunctions () { return array ( 'aurahtml' => 'callHelper' , 'html' => 'callHelper' ); } public function callHelper () { return $this -> helper ; } }

But you are not limited to name it as the same html tag helpers and form helpers.

So that will make the helpers look native Plates helpers. Thank you for this functionality to plugin the helpers.

<?php use League\Plates\Extension\ExtensionInterface ; use Aura\Html\HelperLocator ; class AuraHtmlExtension implements ExtensionInterface { public $engine; public $template; protected $helper; public function __construct( HelperLocator $helper) { $this -> helper = $helper; } public function getFunctions () { return array ( 'anchor' => 'anchor' // ... more functions same as aura ); } public function anchor ($href, $text, array $attr = array ()) { return $this -> helper -> anchor ($href, $text, array $attr); } }

Let us use the basic example in plates and use aura html helper to show the system works as expected.

Create the templates in a templates folder or change the path in Plates Engine.

Profile Template

<?php <!-- profile . php --> <? php $this -> layout ( 'template' ) ?> <?php $this -> title = 'User Profile' ?> < h1 >User Profile</ h1 > < p >Hello, <? = $this -> e ($this -> name ) ?> </ p > < div > <?php echo $this -> aurahtml () -> input ( array ( 'type' => 'color' , 'name' => 'name' , 'value' => 'value' , 'attribs' => array (), 'options' => array (), )); // <input type="color" name="name" value="value" /> echo $this -> html () -> input ( array ( 'type' => 'date' , 'name' => 'name' , 'value' => 'value' , 'attribs' => array (), 'options' => array (), )); // <input type="date" name="name" value="value" /> ?> </ div >

Layout Template

<?php <!-- template . php --> < html > < head > < title ><?= $this -> title ?> </ title > </ head > < body > <? = $this -> content () ?> </ body > </ html >

Autoload Extension

Make sure AuraHtmlExtension can be autoloaded. We can add in composer.json

/ / r e s t o f t h e c o d e "autoload" : { "psr-4" : { "" : "path/to/aura/html/extension/" } }

Bootstrapping and Rendering

<?php // test.php file require __DIR__ . '/vendor/autoload.php' ; $engine = new \League\Plates\Engine ( __DIR__ . '/templates' ); // Create a new template $template = new \League\Plates\Template ($engine); $factory = new \Aura\Html\HelperLocatorFactory (); $helper = $factory -> newInstance (); $engine -> loadExtension ( new AuraHtmlExtension ($helper)); // Assign a variable to the template $template -> name = 'Jonathan' ; // Render the template echo $template -> render ( 'profile' );

If you run php test.php you will see something like this rendered.

< html > < head > < title >User Profile</ title > </ head > < body > < h1 >User Profile</ h1 > < p > Hello, Jonathan </ p > < div > < input type = "color" name = "name" value = "value" /> < input type = "date" name = "name" value = "value" /> </ div > </ body > </ html > </ body ></ title >

Thank you and Happy PhPing!
