Twiggy is not just a simple implementation of Twig template engine for CodeIgniter. It supports themes, layouts, templates for regular apps and also for apps that use HMVC (module support). It is supposed to make life easier for developing and maitaining CodeIgniter applications where themes and nicely structured templates are necessary.
Twig by itself is a very powerful and flexible templating system but with CodeIgniter it is even cooler! With Twiggy you can separately set the theme, layout and template for each page.
What is even more interesting, this does not replace CodeIgniter's default Views, so you can still load views as such: $this->load->view().
- PHP 5.2.4+
- CodeIgniter 2.x
$this->load->spark('twiggy/x.x.x'); where x.x.x is the version you want to load (assuming you have it installed).
-
Create a directory structure:
+-{APPPATH}/ | +-themes/ | | +-default/ | | | +-_layouts/NOTE:
{APPPATH}is the folder where all your controllers, models and other neat stuff is placed. By default that folder is calledapplication. -
Create a default layout
index.html.twigand place it in _layouts folder:<!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8"> <!--[if lt IE 9]> <script src="http://html5shim.googlecode.com/svn/trunk/html5.js"></script> <![endif]--> <title>Default layout</title> </head> <body> {% block content %} {% endblock %} </body> </html> -
Create a default template file
index.html.twigat the root ofdefaulttheme folder:{% extends _layout %} {% block content %} Default template file. {% endblock %} -
You should end up with a structure like this:
+-{APPPATH}/ | +-themes/ | | +-default/ | | | +-_layouts/ | | | | +-index.hml.twig | | | +-index.html.twig
$this->twiggy->display();
In the example above we only displayed the default template and layout. Obviously, you can create as many layouts and templates as you want.
For example, create a new template file welcome.html.twig and load it before sending the output to the browser.
// Whoah, methoding chaining FTW!
$this->twiggy->template('welcome')->display();
Notice that you only need to specify the name of the template (without the extension *.html.twig).
There is much more cool stuff that you should check out by visiting the wiki.
- Fixed a problem with Twig cache. Caching should now work as expected.
- Added
unset_data()method to unset a particular variable, given a key. - Fixed a bug where calling render() would throw
Twig_Error_Loaderexception due to missing file extention. - Added a private method _load() to load the template and return output object where previously this was done both in render() and display() methods separately.
- Added
Twig_Error_Loaderexception handling in render() method.
