Examples of use of assets in Yii, yiiassets example

First, the role of YII assets:

1.yii in the role of assets is convenient for modular, plug-in, generally for security reasons do not allow the URL to access protected the following file , but we want to separate the module, so we need to use the release, A copy of the file under one directory is copied to assets below for easy access via URL

$assets = Yii::getpathofalias (' ext '). ' /css ';//$baseUrl = Yii::app ()->getassetmanager ()->publish ($assets); $baseUrl = Yii::app ()->assetmanager- >publish ($assets); Extensions/css published to assets creates a random, non-conflicting folder under Yii::app ()->clientscript->registercssfile ($BASEURL. /main.css ');//reference assets below the MAIN.CSS

2. If a module needs to add a resource, add it directly from the Webroot.
However, trying to create a module can be referenced anywhere, and resources are independent and can avoid naming conflicts .
How do you guarantee that your file name will not conflict with some fragmented application that attempts to use the same name for Js,images,css?
by Cassetmanager,yii::app ()->assetmanager, you can automatically publish private resources to a common directory Webroot/assets

Second, use example:

The following is an example of admin module to illustrate the use of assets:

1, the need to use the resources under the modules/admin/assets.

2, through the Cassetmanager,yii::app ()->assetmanager can automatically publish the private resources to the public directory of the site Directory/assets

3. Yii will automatically create a random and non-conflicting folder under the/assets of the site directory, such as 2b31b42b, and copy the files from your Modules/admin/assets directory in the past.
Get the following code, modify the protected\modules\admin\adminmodule.php file,

<?phpclass Adminmodule extends cwebmodule{private $_assetsurl; public Function Getassetsurl () {if ($this->_ Assetsurl===null)  $this->_assetsurl=yii::app ()->getassetmanager ()->publish (Yii::getpathofalias (' Application.modules.admin.assets ')); return $this->_assetsurl; Public Function Setassetsurl ($value) {$this->_assetsurl= $value;}}

Then, using $this->module->assetsurl in/protected/modules/admin/views/layouts/main.php, you can call your CSS and other files, as shown in the following code:

You will also need to force the update asset before using the code as follows:

$BASEJSURL = Yii::app ()->getassetmanager ()->publish ($baseJsPath, False,-1, yii_debug);

How the YII framework publishes CSS, JS, and image to assets

But in the spirit of solving the problem, it is found that assets is a good stuff. $cs =yii::app ()->clientscript; $cssDir =yii::getpathofalias ("Access.css"); $published = Yii::app ()->assetmanager->publish ($cssDir); $cssFile = $published. "/" . "Homemain.css"; if (! Yii::app ()->clientscript->iscssfileregistered ($cssFile)) {Yii::app ()->clientscript->registercssfile ($cssFile); }? >2. The Assetmanager used above is described in/web/cassetmanager.php, where the Publish function has the following parameters: $path: Location of files such as CSS, $ Hashbyname whether the resource folder generated under the Assets folder is hashed, $level load mode (single file, folder full load God horse), $forceCopy whether to force the reload every time (I think CSS debugging is better, Otherwise, the modified CSS may not take effect immediately because it does not reload.
