Using Laravel .htaccess to Detect Mobile Devices and Redirect to Mobile Site

This post provides information on how to use Laravel .htaccess to detect mobile devices and redirect users to the mobile version of a website. It includes details on the implementation and offers a demo if necessary.

What is the .htaccess file?

The .htaccess file, which stands for hypertext access file, is a configuration file that operates at the directory level.

Its primary purpose is to configure site access issues such as access security control and URL redirection.

Uses of the .htaccess file

  • URL rewriting
  • Authentication based on the user's IP address
  • Controlling directory listing
  • Managing error responses
  • Allowing server-side caching to reduce bandwidth usage
  • An important advantage of the .htaccess file is that changes made to it take immediate effect because the file is read on each request.

Removing "public" from Laravel URLs using .htaccess involves creating an .htaccess file in the Laravel root directory and adding the following code:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule ^(.*)$ public/$1 [L]
</IfModule>

Managing error responses can be done by using the .htaccess file to address the "404 not found" error:

RewriteEngine on
RewriteBase /RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

Redirecting URLs using .htaccess allows you to redirect your website from xyz.com to www.xyz.com by using the following code:

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

Redirecting to a mobile site using .htaccess can be achieved through two options:

RewriteEngine On
RewriteCond %{QUERY_STRING} !^desktop
RewriteCond %{HTTP_USER_AGENT} "android|blackberry|googlebot-mobile|iemobile|iphone|ipod|#opera mobile|palmos|webos" [NC]
RewriteCond %{HTTP_USER_AGENT} "acs|alav|alca|amoi|audi|aste|avan|benq|bird|blac|blaz|brew|cell|cldc|cmd-" [NC,OR]
RewriteCond %{HTTP_USER_AGENT} "dang|doco|eric|hipt|inno|ipaq|java|jigs|kddi|keji|leno|lg-c|lg-d|lg-g|lge-" [NC,OR]
RewriteCond %{HTTP_USER_AGENT}  "maui|maxo|midp|mits|mmef|mobi|mot-|moto|mwbp|nec-|newt|noki|opwv" [NC,OR]
RewriteCond %{HTTP_USER_AGENT} "palm|pana|pant

|pdxg|phil|play|pluc|port|prox|qtek|qwap|sage|sams|sany" [NC,OR]
RewriteCond %{HTTP_USER_AGENT} "sch-|sec-|send|seri|sgh-|shar|sie-|siem|smal|smar|sony|sph-|symb|t-mo" [NC,OR]
RewriteCond %{HTTP_USER_AGENT} "teli|tim-|tosh|tsm-|upg1|upsi|vk-v|voda|w3cs|wap-|wapa|wapi" [NC,OR]
RewriteCond %{HTTP_USER_AGENT} "wapp|wapr|webc|winw|winw|xda|xda-" [NC,OR]
RewriteCond %{HTTP_USER_AGENT} "up.browser|up.link|windowssce|iemobile|mini|mmp" [NC,OR]
RewriteCond %{HTTP_USER_AGENT} "symbian|midp|wap|phone|pocket|mobile|pda|psp" [NC]RewriteRule ^$ http://m.your_domain.com [L,R=302]

Using Laravel

Alternatively, you can use Laravel routes to redirect users to the mobile site. By creating a function to check if the request is coming from a mobile device, you can call the appropriate routes.

  1. <?php
  2. function isMobile(){
  3.     if(isset($_SERVER['HTTP_USER_AGENT'])){
  4.  
  5.         $useragent=$_SERVER['HTTP_USER_AGENT'];
  6.  
  7.         if(preg_match('/(tablet|ipad|amazon|playbook)|(android(?!.*(mobi|opera
  8.             mini)))/i',strtolower($useragent))){
  9.             return true ;
  10.         };
  11.  
  12.  
  13.             if(preg_match('/(android|bbd+|meego).+mobile|avantgo|bada/|blackberry|blazer|compal|elaine|fennec|hiptop|iemobile|ip(hone|od)|iris|kindle|lge

  32.     }
  33. 	return 0;
  34. }
  35.  
  36. if(isMobile()){
  37. 	include_once(app_path().'/routes/mobile_routes.php');
  38. }else{
  39. 	require_once(app_path().'/routes/website_routes.php');
  40. }
  41. ?>

The .htaccess file can also be used to easily redirect a domain to a subdomain.
