Yii::setAlias('backend', dirname(dirname(__DIR__)) . '/backend'); — tara, Jul 16 '17 at 15:21
can you give us $path for one of your files and the path you set for your images to show in frontend — Ebrahim Poursadeqi, Jul 16 '17 at 15:26
url that my image in frontend have : src="uploads/'.$model->image_web_filename.'" url that my image have: blog/frontend/web/uploads/'.$model->image_web_filename.'" — tara, Jul 16 '17 at 15:31
this error is not related to aliases,this tell that yii can't route to `post/index` do you have PostController.php file and how you call url , like this `index.php?r=post/index` or `index.php/post/index` — Ebrahim Poursadeqi, Jul 19 '17 at 06:42
yes i have because i load this page this url show error. for each page this diffrent and when i use alias shoe this error whith out this work fine.i use index.php/post/index — tara, Jul 19 '17 at 06:45
can you provide your question with aliases that you have added? — Ebrahim Poursadeqi, Jul 19 '17 at 06:53
if you remove two lines in aliases.php you get this error again? and you replaced `http://frontend.sample.dev` with your real front end path? — Ebrahim Poursadeqi, Jul 19 '17 at 07:41
when i remove two lines in aliases i did not get error. yes i replaced that with:http://yii.com — tara, Jul 19 '17 at 08:02
you should not replace with yii.com, you have to replace it with `localhost` path to your project.for example `http://localhost/frontend/` or path you have — Ebrahim Poursadeqi, Jul 19 '17 at 08:39
i decided to save image in frontend and backend together and use them. thank you for your help — tara, Jul 19 '17 at 08:57

i'm pretty late to the party
but i got a few bones to pick with this solution provided.. so here it goes:

you mention you have different front and back configurations
so you are serving different folders for yii.com/:80 and yii.com/:81 respectively /frontend/web and /backend/web.
keeping this in mind,
no amount of aliases can make content of one of them available to the other.
the yii-advanced-app has @frontend and @backend aliases defined in common/config/bootstrap
```
Yii::setAlias('@common', dirname(__DIR__));
Yii::setAlias('@frontend', dirname(dirname(__DIR__)) . '/frontend');
Yii::setAlias('@backend', dirname(dirname(__DIR__)) . '/backend');
Yii::setAlias('@console', dirname(dirname(__DIR__)) . '/console');
```
DO NOT CHANGE THESE unless you know very well what you're doing.
Yii is using these aliases to autoload classes defined under these namespaces common, frontend, backend and console. this exact thing is causing the ridiculous chain of "errors occurring while handling other errors"
more details on Yii autloading documentaion

you can simply share content of these folders by creating a symlink from frontend/web/uploads to backend/web/uploads.

your webserver config (or .htaccess) will require the +FollowSymLinks option

Yii can manage this if you add a few lines to the environments/index.php file

'Development' => [
    // .. other options
    'setWritable'            => [
        // .. leave the default stuff there
        'frontend/web/uploads',
    ],
    'createSymlink'          => [
        // link                =>   real folder
        'backend/web/uploads'  => 'frontend/web/uploads',
    ]
],
'Production'  => [
    // .. 
    'setWritable'            => [
        // .. 
        'frontend/web/uploads',
    ],
    'createSymlink'          => [
        // link                =>   real folder
        'backend/web/uploads'  => 'frontend/web/uploads',
    ]
],

and then run the init command again, just like in the installation guide (you do have to option to not overwrite local config files)
if you are running under windows, this might now ask you for elevated privileges

php init

or if you chose to make the symlinks manually you can try this quick guide

you can try this solution :

Yii::setAlias('@frontend', 'http://frontend.sample.dev');
Yii::setAlias('@backend', 'http://backend.sample.dev');

and if you upload files in backend set the src parameter of image to

Yii::getAlias('@backend/path/to/your/image/file');

and if you save your files in frontend replace @backend with @frontend

create this function in components folder

   namespace common\components;

use Yii;

class Helper extends \yii\web\Request {

    public static function getFrontendUrl($path) {
        $frontUrl = str_replace('/adminpanel', '', $path);
        return $frontUrl;
    }

}

and use in backend :

$path \common\components\Helper::getFrontendUrl(Yii::$app->request->baseUrl).$img;

notic: in frontend You do not need
