Auto Mobile Site Redirect

Question

I just made my first jQuery mobile site.

I want to have people that view my \"Full Site\" with a mobile phone automatically get transferred to the \"MOBILE SITE\".

Answer 1

<script type="text/javascript">
        if (screen.width <= 720) {
        window.location = "mobile/index.php";
    }
</script>

Answer 2

You could use something like Device Atlas to pick up if it is a mobile device and then send the appropriate version of the page.

There are other hacks you can do to look at the devices user agent too.

Answer 3

There are multiple ways listed here, including PHP.

The jQuery one sets the variable jQuery.browser.mobile:

/**
 * jQuery.browser.mobile (http://detectmobilebrowser.com/)
 *
 * jQuery.browser.mobile will be true if the browser is a mobile device
 *
 **/

After this you can redirect with ordinary JS, like this:

if(jQuery.browser.mobile) window.location = 'mobile_url';

Remember that it's not good to redirect the user on every page. Either make a separate mobile site or do it server-side (with e.g. PHP).

iPhone & iPod Detection Using JavaScript

http://davidwalsh.name/detect-iphone

if((navigator.userAgent.match(/iPhone/i)) || (navigator.userAgent.match(/iPod/i))) {
   if (document.cookie.indexOf("iphone_redirect=false") == -1) window.location = "http://graves-incorporated.com/test_sites/solera_mobile/";
}

The PHP

if(strstr($_SERVER['HTTP_USER_AGENT'],'iPhone') || strstr($_SERVER['HTTP_USER_AGENT'],'iPod'))
{
  header('Location: http://yoursite.com/iphone');
  exit();
}

Answer 5

For those of you looking for a serverside solution since that is way more efficient check this link I just found, which is a quite comprehensive list of user agents you can check to redirect on : http://detectmobilebrowsers.com/

For those of you that don't know the user agent is part of the header of the request and describes the client software that oriniganated the request. Basicly its a string that you can use to identify which device requested your web page.
