Creating Web Page Templates with PHP and Twig (part 1)Enforced Separation. There’s no shortage of PHP template engines and they’re all very similar, often differing only in implementation details and support for specific features. They all serve the same purpose: that of functionally separating a Web application’s user interface from its business logic, and thereby enabling developers and interface designers to work on the same application without getting in each other’s hair. Most PHP frameworks, including Zend Framework, Agavi, Cake. PHP and Code. Igniter, come with built- in templating to enable this separation. However, if you’re not a big fan of frameworks, or if your project is small enough that you don’t need the additional overhead, you can also consider using a standalone template engine to obtain the same benefits. A number of such engines exist – you’ve probably already heard of Smarty, Savant, Dwoo and others – and in this article, I’ll introduce you to one I discovered rather recently, called Twig.

First, it assumes that you know the basics of PHP and database programming, and you have a reasonably- good understanding of using objects and object methods in PHP. Second, it assumes that you have an Apache/PHP/My. SQL development environment already set up, and that you’ve managed to successfully install Twig. If you’re using the automated PEAR installer, you can install Twig simply by running the following commands at your command prompt. Twigshell> pear channel- discover pear. Twig. Alternatively, you can manually install Twig, by downloading it from here. Twig is currently maintained by Sensio Labs and Fabien Potencier, who is also the creator of the Symfony framework, and is released under the new BSD License. This article uses Twig v. Before you can start using Twig, a quick overview of the basics. Consider that the typical PHP application consists of a number of Web pages, each containing a combination of static HTML elements (navigation menus, lists, images and so on) and dynamic content (data from a database, an XML file, a Web service and so on). Twig provides a way to separate the two, by creating templates containing placeholders for the dynamic content and proving an API to inject “real” content into these placeholders at run- time. The value for the placeholders are defined inside a controlling PHP script; this script also takes care of the intricacies of database connections and queries, XML processing and additional calculations. Through this process, the Web page is generated by interpolating content from two sources: the template, which contains the static user interface elements and placeholders, and the controlling PHP script, which retrieves data for the placeholders from the appropriate data sources. Programmers and user interface designers are now able to work on the same Web page simultaneously, without needing significant additional coordination (apart from agreeing on the names of the common placeholder variables). Locked and Loaded. To see how this works, here’s a simple illustrative template. Account successfully created!& lt; /h. Hello {{ name }}& lt; /p>. Thank you for registering with us. Your account details are as follows: & lt; /p>. Username: {{ username }} & lt; br/>. Password: {{ password }}. You've already been logged in, so go on in and have some fun!& lt; /p>. Account successfully created!& lt; /h. Hello{{name}}& lt; /p> & lt; p> Thank you forregistering with us. Your account details are asfollows: & lt; /p> & lt; pstyle="margin- left: 1. Username: {{username}}& lt; br/> Password: {{password}} & lt; /p> & lt; p> You've already been logged in,so go on inandhave some fun!& lt; /p> & lt; /body> & lt; /html> Save this file as templates/thanks. Notice that the placeholder variables are surrounded by two sets of curly braces; this tells Twig that they are template variables and must be replaced with actual values at run- time. Next, create a controller script that populates these variables with actual data and renders the composite output. Twig auto- loader. Twig/Autoloader. php'. Twig_Autoloader: :register(). Twig_Loader_Filesystem('templates'). Twig environment. Twig_Environment($loader). Template('thanks. Clark Kent'. 'username' => 'ckent'. Exception $e) {. die ('ERROR: ' . Message()). ?> 1. Twig auto- loaderinclude'Twig/Autoloader. Twig_Autoloader: :register(); try{ // specify where to look for templates $loader=new. Twig_Loader_Filesystem('templates'); // initialize Twig environment $twig=new. Twig_Environment($loader); // load template $template=$twig- > load. Template('thanks. Clark Kent', 'username'=> 'ckent', 'password'=> 'krypt. Exception$e){ die('ERROR: '.$e- > get. Message()); }?> And now, when you access this PHP script through a browser, you should see something like this: There’s a fairly standard sequence to rendering a template using Twig: Initialize the Twig autoloader. This registers the Twig autoloader with PHP, so that Twig classes and plugin files are automatically found and loaded as needed. Initialize a template loader. This is done by creating an instance of a class which implements the Twig_Loader. Interface – in this case, the Twig_Loader_Filesystem. The object constructor is passed the name of the directory in which to look for templates. Initialize the Twig environment. This is done by creating an instance of Twig_Environment, which stores the current Twig configuration. Load a template. The environment object exposes a load. Template() method, which can be passed a template file name and which finds and loads the relevant template into memory. The return value of this method is a template instance. Set values for template variables and render the template. A new associative array, whose values correspond to template variable names, should be defined and then passed to the template object’s render() method. The render() method interpolates the values from the data array into the template object, generating and rendering the composite result. Getting Even. Twig also lets you conditionally display content within a template, through its ‘if- else- endif’ control structure. Here’s a simple example of a template that uses this structure. Odd or Even& lt; /h. Odd or. Even& lt; /h. Depending on the number generated within the PHP controller script, the template will display one of two possible messages. Here’s the controller script, which randomly picks a number between 0 and 3. Twig auto- loader. Twig/Autoloader. php'. Twig_Autoloader: :register(). Twig_Loader_Filesystem('templates'). Twig environment. Twig_Environment($loader). Template('numbers. Exception $e) {. die ('ERROR: ' . Message()). ?> 1. Twig auto- loaderinclude'Twig/Autoloader. Twig_Autoloader: :register(); try{ // define template directory location $loader=new. Twig_Loader_Filesystem('templates'); // initialize Twig environment $twig=new. Twig_Environment($loader); // load template $template=$twig- > load. Template('numbers. Exception$e){ die('ERROR: '.$e- > get. Message()); }?> Here’s a sample of the output: You can also handle multiple conditions within a Twig template, through the ‘if- elseif- else- endif’ control structure. Here’s an example of a template that uses this. Seasons& lt; /h. Spring is here, watch the flowers bloom! Summer is here, time to hit the beach! Autumn is here, watch the leaves slowly fall! Winter is here, time to hit the slopes! Seasons& lt; /h. Spring ishere,watchtheflowersbloom! {%elseifmonth> 3andmonth& lt; =6%} Summer ishere,timetohitthebeach! {%elseifmonth> 6andmonth& lt; =9%} Autumn ishere,watchtheleavesslowlyfall! {%elseifmonth> 9andmonth& lt; =1. Menggunakan Web Template pada Code Igniter=- 1. Untuk mengaktifkan URL Helper pada autoload ubah baris berikut: $autoload[‘helper’] = array(); menjadi$autoload[‘helper’] = array(‘url’); 4. Untuk Mengaktifkan default controller ubah baris$route[‘default_controller’] = ‘welcome’; menjadi$route[‘default_controller’] = “nama_file_controller”; 5. Buat File Controller i direktori: ./system/application/controllers/nama_file_controller. Tuliskan baris berikut: < ? Pertama extends Controller {function Pertama(){parent: :Controller(); }function index(){$this- > load- > view(‘nama_tampilan’); }}?> 6. Ekstrak file template hasil download, lalu rename file html tampilannya (biasanya bernama: index.
