重定向在Opera中有效，但在fennec和其他移动浏览器中无效吗？

Question

I have a mobile website and I am redirecting mobile users from main website to mobile website. But I have also given option on my mobile website that if some mobile user want to visit the main website he can. To solve the problem I wrote this code on my main website

if (is_mobile()== true) //if user is browsing from mobile
{

    $main_website_url= 'http://localhost/www/redsignal/';   // main website URL

    $mobilesite_url = 'http://localhost/www/redsignal-mobile/';  //mobile website URL

    $mobilesite_url_length = strlen($mobilesite_url);

    $referring_path_url = substr($_SERVER['HTTP_REFERER'], 0 , $mobilesite_url_length);

    if ($referring_path_url == $mobilesite_url) //This if condition checks that if the mobile user is coming from my mobile website or not
    {
        header("Location:".$main_website_url);  // if he is coming from mobile he will be redirected to main website                
    }
    else
    {
        header("Location:".$mobilesite_url); // if not than he will be redirected to mobile website     
    }


}

Answer 1

You need to use another variable in order to distinguish whether you want to force show original site when click on visit original site in mobile site. For this u can pass GET variable for eg

http://localhost/www/redsignal/?force_show_original=1

Then in your code you change this

if (is_mobile()== true)

to

if (is_mobile()== true || $GET["force_show_original"] == true)

let me know whether it worked

UPDATE

Use following code to redirect site

if (is_mobile()== true || $GET["force_show_original"] == false) {
       //redirect to mobile site
}
else if(is_mobile()== true || $GET["force_show_original"] == true) {
       // redirect to original site
}
else {
       // redirect to original site
}

如果标题不起作用，则可以使用javascript进行重定向，例如

echo "<script type='text/javascript'> document.location.href='$main_website_url'</script> ";
