I have a bit of php code on index.php of my main site, here... http://dominionroofing.com/
This code redirects visitors on mobile browsers to my mobile version of the site, here... http://dominionroofing.com/m/
On the mobile site, the visitor has the option to view the full site, as follows...
<a href="http://dominionroofing.com/?mode=desktop">View Full Website</a>
Here is the part of the php code that is supposed to redirect to the desktop if the link is clicked...
$mode = "mobile";
$mode = "desktop";
$mode = is_mobile() ? "mobile" : "desktop";
if ($mode == "mobile")
header ("Location: http://dominionroofing.com/m/");
However, this is not working, at least not for me on my iphone. I have this exact code installed on quite a few other sites, and it works on all of them but this one. Hosting is GoDaddy shared host, but I have at least two other sites installed on GoDaddy servers that are working perfectly.
Any and all help is much appreciated.
