Solution 1:

I got it working in yii2. Enable mod_rewrite for Apache. For basic template do the following: Create a .htaccess file in web folder and add this

RewriteEngine on
# If a directory or a file exists, use it directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# Otherwise forward it to index.php
RewriteRule . index.php

Then inside config folder, in web.php add to components

'urlManager' => [
    'class' => 'yii\web\UrlManager',
    // Disable index.php
    'showScriptName' => false,
    // Disable r= routes
    'enablePrettyUrl' => true,
    'rules' => array(
            '<controller:\w+>/<id:\d+>' => '<controller>/view',
            '<controller:\w+>/<action:\w+>/<id:\d+>' => '<controller>/<action>',
            '<controller:\w+>/<action:\w+>' => '<controller>/<action>',
    ),
],

In the case of advanced template create the .htaccess files inside backend/web and frontend/web folders and add urlManager component inside common/config/main.php

Solution 2:

First important point is that

Module_Rewrite is enabled on your server(LAMP,WAMP,XAMP..etc) For do URL rewiring in yii2 framework Create one .htaccess file and put in /web folder

RewriteEngine on
# If a directory or a file exists, use it directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# Otherwise forward it to index.php
RewriteRule . index.php

Second step

Config folder common/config/main-local.php add to components array

'urlManager' => [
   'class' => 'yii\web\UrlManager',
   // Disable index.php
   'showScriptName' => false,
   // Disable r= routes
   'enablePrettyUrl' => true,
   'rules' => array(
      '<controller:\w+>/<id:\d+>' => '<controller>/view',
      '<controller:\w+>/<action:\w+>/<id:\d+>' => '<controller>/<action>',
      '<controller:\w+>/<action:\w+>' => '<controller>/<action>',
   ),
],

Solution 3:

For me, the problem was:

  1. Missing .htaccess in the web folder just like mentioned above.
  2. The AllowOverride directive was set to None, which disabled URL rewrites. I changed it to All and now pretty URLs work nicely.
<Directory "/path/to/the/web/directory/">
  Options Indexes 
  FollowSymLinks MultiViews 
  AllowOverride All 
  Require all granted
</Directory>

Solution 4:

First, create a .htaccess at root folder in your Yii2 project with following content:

Options +Indexes

<IfModule mod_rewrite.c> 
  RewriteEngine on

  RewriteCond %{REQUEST_URI} !^public
  RewriteRule ^(.*)$ frontend/web/$1 [L] 
</IfModule>

# Deny accessing below extensions
<Files ~ "(.json|.lock|.git)">
Order allow,deny
Deny from all
</Files>

# Deny accessing dot files
RewriteRule (^\.|/\.) - [F]

Create another .htaccess file in your web folders with following content:

frontend/web/ add backend/web/ Don't forget to add .htaccess file to both web folders:

RewriteEngine on

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d 

RewriteRule . index.php

Now It's done. Change your URL configuration in Yii2:

<?php

use \yii\web\Request;
$baseUrl = str_replace('/frontend/web', '', (new Request)->getBaseUrl());


$config = [
    'components' => [
        'request' => [
            // !!! insert a secret key in the following (if it is empty) - this is required by cookie validation
            'cookieValidationKey' => 'aiJXeUjj8XjKYIG1gurMMnccRWHvURMq',
            'baseUrl' => $baseUrl,
        ],
         "urlManager" => [
            'baseUrl' => $baseUrl,
            'enablePrettyUrl' => true,
            'showScriptName' => false,
            "rules" => [
                "home" => "site/index",
                "about-us" => "site/about",
                "contact-us" => "site/contact",
            ]
        ]
    ],
];

return $config;

Your URL will change to:

localhost/yii2project/site/about => localhost/yii2project/about-us localhost/yii2project/site/contact => localhost/yii2project/contact-us localhost/yii2project/site/index => localhost/yii2project/home

You can access your admin through

localhost/yii2project/backend/web
