检查Yii中是否存在文件

Question

I am creating a bunch of modules that all extend a base module. However, some actions need to override the base view. In that case, I'd like to check if the new module has a view in its structure. If it does, use that view, and otherwise use the base one. Now, my question:

Is there a way to check if a file exists in Yii, using the typical alias structure application.views.user.basic_view without using or importing it?

Answer 1

Try use Controller or CWidget method getViewFile

Answer 2

未经测试，但是解决路径的别名是什么，然后检查这个......

 echo is_file(Yii::getPathOfAlias('application.views.user.basic_view'))?'yes':'no';
