How to get root directory in yii2

Question

yii2 Question

My yii2 install in d:\\wamp\\www\\yii2store

I want to get above path to save images which will be uploaded by me

Answer 1

Open file D:\wamp\www\yiistore2\common\config\params-local.php

Paste below code before return

Yii::setAlias('@anyname', realpath(dirname(__FILE__).'/../../'));

After inserting above code in params-local.php file your file should look like this.

Yii::setAlias('@anyname', realpath(dirname(__FILE__).'/../../'));

return [
];

Now to get path of your root (in my case its D:\wamp\www\yiistore2) directory you can use below code in any php file.

echo Yii::getAlias('@anyname');

Answer 2

Open below file C:\xampp\htdocs\project\common\config\params-local.php

Before your code:

<?php

return [


];

after your code:

<?php
yii::setAlias('@path1', 'localhost/foodbam/backend/web');

return [


];

Answer 3

To get the base URL you can use this (would return "http:// localhost/yiistore2/upload")

Yii::app()->baseUrl

The following Code would return just "localhost/yiistore2/upload" without http[s]://

Yii::app()->getBaseUrl(true)

Or you could get the webroot path (would return "d:\wamp\www\yii2store")

Yii::getPathOfAlias('webroot')

Answer 4

If you want to get the root directory of your yii2 project use, assuming that the name of your project is project_app you'll need to use:

echo Yii::getAlias('@app');

on windows you'd see "C:\dir\to\project_app"

on linux you'll get "/var/www/dir/to/your/project_app"

I was formally using:

echo Yii::getAlias('@webroot').'/..';

I hope this helps someone

Answer 5

Use "getAlias" in Yii2

   \Yii::getAlias('@webroot')

Answer 6

Try out this,

My installation is at D:\xampp\htdocs\advanced

\Yii::$app->basePath will give like D:\xampp\htdocs\advanced\backend.

\Yii::$app->request->BaseUrl will give like localhost\advanced\backend\web\

You may store the image using \Yii::$app->basePath and show it using \Yii::$app->request->BaseUrl
