Yii2. Access to higher level folder

Question

Simple question. I use Yii2 advanced template. In apache I have DocumentRoot "{$path}/www/yii-application1/frontend/web". How can I access /www/yii-application1/uploads in order to show image to user? Following code does not work:

<?php echo Html::img('../../uploads/ring.jpg') ?>

It works with DocumentRoot "{$path}/www/yii-application1/". But in this case an index page of website looks like domain.com/frontend/web. But I need just domain.com.

Answer 1

You can also use alise inside config array on web.php file of config folder like

 'aliases' => [
    '@uploads' => '@app/web/upload',
],

and use it in any where you want like

 <?= Html::img("@uploads/image/xyz.png", ['class' => 'retina']); ?>

Step : 1

First create .htaccess file in here yii-application1/.htaccess

Options +FollowSymlinks
RewriteEngine On

# deal with backend first
RewriteCond %{REQUEST_URI} /(backend)
RewriteRule ^backend/assets/(.*)$ backend/web/assets/$1 [L]
RewriteRule ^backend/css/(.*)$ backend/web/css/$1 [L]
RewriteRule ^backend/image/(.*)$ backend/web/image/$1 [L]

RewriteCond %{REQUEST_URI} !/backend/web/(assets|css|image)/
RewriteCond %{REQUEST_URI} /(backend)
RewriteRule ^.*$ backend/web/index.php [L]


RewriteCond %{REQUEST_URI} /(assets|css|js|img|font)
RewriteRule ^assets/(.*)$ frontend/web/assets/$1 [L]
RewriteRule ^css/(.*)$ frontend/web/css/$1 [L]
RewriteRule ^js/(.*)$ frontend/web/js/$1 [L]
RewriteRule ^image/(.*)$ frontend/web/image/$1 [L]

RewriteCond %{REQUEST_URI} !/(frontend|backend)/web/(assets|css|js|image|font)/
RewriteCond %{REQUEST_URI} !index.php
RewriteCond %{REQUEST_FILENAME} !-f [OR]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^.*$ frontend/web/index.php

Step : 2

Now create a components/Request.php file in common directory and write below code in this file.

Request.php file

<?php

  namespace common\components;

  class Request extends \yii\web\Request 
  {
     public $web;
     public $adminUrl;

     public function getBaseUrl(){
        return str_replace($this->web, "", parent::getBaseUrl()) . $this->adminUrl;
     }

     public function resolvePathInfo(){
        if($this->getUrl() === $this->adminUrl){
            return "";
        }else{
            return parent::resolvePathInfo();
        }
     }
  }
?>

Step : 3

Now Installing component. Write below code in frontend/config/main.php and backend/config/main.php files respectively.

//Frontend
'components' => [
    'user' => [
        'identityClass' => 'common\models\User',
        'enableAutoLogin' => true,
        'identityCookie' => [
            'name' => '_frontendUser', // unique for frontend
        ]
    ],
    'session' => [
        'name' => 'PHPFRONTSESSID',
        'savePath' => sys_get_temp_dir(),
    ],
    'urlManager' => [
        'enablePrettyUrl' => true,
        'showScriptName' => false,
        'rules' => [
            '<alias:>' => 'site/<alias>',
        ],
    ],
    'request'=>[
        'cookieValidationKey' => '[gfhjghsdjks44fdf4fgf4fgfg5645ggxcvvc]',
        'csrfParam' => '_frontendCSRF',
        'class' => 'common\components\Request',
        'web'=> '/frontend/web'
    ],
]

//Backend 
'components' => [
    'user' => [
        'identityClass' => 'common\models\User',
        'enableAutoLogin' => false,
        'identityCookie' => [
            'name' => '_backendUser', // unique for backend
        ]
    ],
    'session' => [
        'name' => 'PHPBACKSESSID',
        'savePath' => sys_get_temp_dir(),
    ],
    'urlManager' => [
        'enablePrettyUrl' => true,
        'showScriptName' => false,
        'rules' => [
        ],
    ],
    'request'=>[
        'cookieValidationKey' => '[ruiqwybnddiogj786789hzcassdas9dasdjufi]',
        'csrfParam' => '_backendCSRF',
        'class' => 'common\components\Request',
        'web'=> '/backend/web',
        'adminUrl' => '/backend'
    ],
]

Your domain.com/frontend/web problem solved to follow the above steps. and you can access the index page for domain.com/frontend/web using domain.com.

Now You can access you image using

<?php echo Html::img('uploads/ring.jpg') ?>

Also you can access the domain.com/frontend/web/image using below code

<?= Html::img(Yii::getAlias('@web').'/image/xyz.png', ['class' => 'retina']); ?>

also you get webroot path using this Yii::getAlias('@webroot')
