[gwolff2005]

Hi guys, I need your help, I am very desperate.

I want people visitng my site with a mobile browser seeing a window saying, would you liek to switch to mobile view? - and the redirect.

 

I found this code and I tried to implement it in my php fiel but nothing changes.

Mobile borwser goes immediately to mobile view without window asking first,

could do something like this

echo $_SERVER['HTTP_USER_AGEENT'];

Try starting your session first.  Why do you want to make it a result of some condition?  Just start it!

[Mancent]

if(preg_match("/chrome/",strtolower($_SERVER['HTTP_USER_AGENT'])))
{
//use a different css maybe
}
elseif(preg_match("/msie/",strtolower($_SERVER['HTTP_USER_AGENT'])))
{
//use a different css maybe
}
elseif(preg_match("/opera/",strtolower($_SERVER['HTTP_USER_AGENT'])))
{
//use a different css maybe
}
elseif(preg_match("/firefox/",strtolower($_SERVER['HTTP_USER_AGENT'])))
{
//use a different css maybe
}
elseif(preg_match("/safari/",strtolower($_SERVER['HTTP_USER_AGENT'])))
{
//use a different css maybe
}

then add some if statements

Thanks for your input

@ ginerjm
How would I start the session first, if I want to detect First if it is mobile or not and if yes redirect. If that is not necessary how owuld I code it then?

@Mancent:
My problem is that the window does not pop up in my code which it is supposed to do.

[Mancent]

do you also have the popupbox.htm created?

so your sending a var un the address bar.

http://somewebsite.com/index.php?mVar=1 everything pop up just fine on PC I and my IPHONE

You should consider Responsive Web Design. Browser detection just means more work for you because then you essentially maintain two websites.

@ Mancent. Thanks for the code. I will try it now. I have the popupbox.htm.
@Skunkbad: Some of it I pull over from my normal site so I dont have to maintain too much...
