Twitter Bootstrap widgets |

========================= |
||||
Bootstrap widgets |
||||
================= |
||||
|
||||
Overview |
||||
-------- |
||||
Yii includes support of [Bootstrap 3](http://getbootstrap.com/) markup and components framework out of the box. It is an |
||||
excellent framework that allows you to speed up development a lot. |
||||
|
||||
Bootstrap is generally about two parts: |
||||
|
||||
- Basics such as grid system, typography, helper classes and responsive utilities. |
||||
- Ready to use components such as menus, pagination, modal boxes, tabs etc. |
||||
|
||||
Basics |
||||
------ |
||||
|
||||
Yii doesn't wrap bootstrap basics into PHP code since HTML is very simple by itself in this case. You can find details |
||||
about using the basics at [bootstrap documentation website](http://getbootstrap.com/css/). Still Yii provides a |
||||
convenient way to include bootstrap assets in your pages with a single line added to `AppAsset.php` located in your |
||||
`config` directory: |
||||
|
||||
```php |
||||
public $depends = array( |
||||
'yii\web\YiiAsset', |
||||
'yii\bootstrap\BootstrapAsset', // this line |
||||
); |
||||
``` |
||||
|
||||
Using bootstrap through Yii asset manager allows you to combine and minimize its resources with your own ones when |
||||
needed. |
||||
|
||||
Yii widgets |
||||
----------- |
||||
|
||||
Most complex bootstrap components are wrapped into Yii widgets to allow more robust syntax and integrate with |
||||
framework features. All widgets belong to `\yii\bootstrap` namespace. Let's review these. |
||||

||||

View |
||||
==== |
||||
|
||||
View is an important part of MVC and is reponsible for how data is presented to the end user. |
||||
|
||||
Basics |
||||
------ |
||||
|
||||
Yii uses PHP in view templates by default so in a web application a view typically contains some HTML, `echo`, `foreach` |
||||
and such basic constructs. It may also contain widget calls. Using complex code in views is considered a bad practice. |
||||
Such code should be moved to controller or widgets. |
||||
|
||||
View is typically called from controller action like the following: |
||||
|
||||
```php |
||||
public function actionIndex() |
||||
{ |
||||
return $this->render('index', array( |
||||
'username' => 'samdark', |
||||
)); |
||||
} |
||||
``` |
||||
|
||||
First argument is the view name. In context of the controller Yii will search for its views in `views/site/` where `site` |
||||
is controller ID. For details on how view name is resolved please refer to [yii\base\Controller::render] method. |
||||
Second argument is data array that contains key-value pairs. Value is available in the view as a variable named the same |
||||
as the corresponding key. |
||||
|
||||
So the view for the action above should be in `views/site/index.php` and can be something like: |
||||
|
||||
```php |
||||
<p>Hello, <?php echo $username?>!</p> |
||||
``` |
||||
|
||||
Intead of just scalar values you can pass anything else such as arrays or objects. |
||||
|
||||

|
||||
Security |
||||
-------- |
||||
|
||||
One of the main security principles is to always escape output. If violated it leads to script execution and, |
||||
most probably, to cross-site scripting known as XSS leading to leaking of admin passwords, making a user to automatically |
||||
perform actions etc. |
||||
|
||||
Yii provides a good toolset in order help you escaping your output. The very basic thing to escape is a text without any |
||||
markup. You can deal with it like the following: |
||||
|
||||
```php |
||||
<?php |
||||
use yii\helpers\Html; |
||||
?> |
||||
|
||||
<div class="username"> |
||||
<?php echo Html::encode($user->name); ?> |
||||
</div> |
||||
``` |
||||
|
||||
When you want to render HTML it becomes complex so we're delegating the task to excellent |
||||
[HTMLPurifier](http://htmlpurifier.org/) library. In order to use it you need to modify your `composer.json` first by |
||||
adding the following to `require`: |
||||
|
||||
```javascript |
||||
"ezyang/htmlpurifier": "v4.5.0" |
||||
``` |
||||
|
||||
After it's done run `php composer.phar install` and wait till package is downloaded. Now everything is prepared to use |
||||
Yii's HtmlPurifier helper: |
||||
|
||||
```php |
||||
<?php |
||||
use yii\helpers\HtmlPurifier; |
||||
?> |
||||
|
||||
<div class="post"> |
||||
<?php echo HtmlPurifier::process($post->text); ?> |
||||
</div> |
||||
``` |
||||
|
||||
Note that besides HTMLPurifier does excellent job making output safe it's not very fast so consider |
||||
[caching result](caching.md). |
||||
|
||||
Alternative template languages |
||||
------------------------------ |
||||
|
||||
There are offlicial extensions for [Smarty](http://www.smarty.net/) and [Twig](http://twig.sensiolabs.org/). In order |
||||
to learn more refer to [Using template engines](template.md) section of the guide. |
