A summary of common path methods in Yii

A summary of how to use some common path methods in the Yii framework.

Add CSS files or JavaScript files in the controller:

Yii::app()->clientScript->registerCssFile(Yii::app()->baseUrl.'/css/my.css'); 
Yii::app()->clientScript->registerScriptFile(Yii::app()->baseUrl.'/css/my.js'); 
<?php echo $this->module->assetsUrl; ?>/css/main.css

Call the js of framework/web/js/source in the YII framework. The file called by the registerCoreScript key can be viewed in the framework/web/js/packages.php list:

Yii::app()->clientScript->registerCoreScript('jquery');

Get the ID of the current controller in the view:

Yii::app()->getController()->id;

Get the ID method of the current action in the view:

Yii::app()->getController()->getAction()->id;

yii gets ip address

Yii::app()->request->userHostAddress;

yii determines whether the submission method is a post request

Yii::app()->request->isPostRequest

yii determines whether it is an ajax request

Yii::app()->request->isAjaxRequest

Get the current domain name:

Yii::app()->request->hostInfo

Get the physical path of the protected directory

YII::app()->basePath;

Get the url of the previous page to return

Yii::app()->request->urlReferrer;

Get the current url

Yii::app()->request->url;

Get current home url

Yii::app()->homeUrl

Get the current return url

Yii::app()->user->returnUrl

Project path

dirname(Yii::app()->BasePath)

If you have a directory with some commonly used classes or files, you can define a path alias at the top of main.php, and the alias can be translated into its corresponding path.

Yii::getPathOfAlias('webroot')

If there are multiple configurations, you can add a configuration to the array in main.php.
