Hi everyone,

oik so there is this design im doing for a new site and the problem is that the site does not display properly in Internet Explorer but it does in firefox. How do i get the site to redirect you to a page that says somthing like "you need to have firefox instalkled to view this page" if you are not running firefox?

I thought you might want to look into this. I got this code snippet a long time ago. ^_~

CODE

<?php

function browser_detection( $which_test ) {

    // initialize the variables
    $browser = '';
    $dom_browser = '';

    // set to lower case to avoid errors, check to see if http_user_agent is set
    $navigator_user_agent = ( isset( $_SERVER['HTTP_USER_AGENT'] ) ) ? strtolower( $_SERVER['HTTP_USER_AGENT'] ) : '';

    elseif (stristr($navigator_user_agent, "msie 4"))
    {
        $browser = 'msie4';
        $dom_browser = false;
    }

    elseif (stristr($navigator_user_agent, "msie"))
    {
        $browser = 'msie';
        $dom_browser = true;
    }

    elseif (stristr($navigator_user_agent, "mozilla/4"))
    {
        $browser = 'ns4';
        $dom_browser = false;
    }

    else
    {
        $dom_browser = false;
        $browser = false;
    }

    // return the test result you want
    if ( $which_test == 'browser' )
    {
        return $browser;
    }
    elseif ( $which_test == 'dom' )
    {
        return $dom_browser;
        //  note: $dom_browser is a boolean value, true/false, so you can just test if
        // it's true or not.
    }
}

?>

The above function can be called by:

CODE

$user_browser = browser_detection('browser');

if ( $user_browser == 'opera' )
{
do something;
}

or you may want:

CODE

if ( browser_detection('dom') )
{
execute the code for dom browsers
}
else
{
execute the code for non DOM browsers
}

and so on.......

Declare the function definition inlined with other function definitions of your php page or just simply put it on the top.

As for the usage, you can place the if(...) statement where you would like the script to be executed, like:

CODE

/* Log in and verification or something you want to be executed first */
/* Continue */
/* Then if you want to detect browser now use the browser detection */
/* Sample */
$this_browser = browser_detection('browser');

if($this_browser == 'msie' || $this_browser == 'msie4'){
// Redirect user
} else {
// continue loading page
}

Oh I see.... What you posted is an HTML file. You need to have a PHP file to run this codes. Does your host support PHP? If yes, make an index.php and put this.. inside

CODE

<?php

global $this_browser;

function browser_detection( $which_test ) {

    // initialize the variables
    global $browser = '';
    global $dom_browser = '';

    // set to lower case to avoid errors, check to see if http_user_agent is set
    $navigator_user_agent = ( isset( $_SERVER['HTTP_USER_AGENT'] ) ) ? strtolower( $_SERVER['HTTP_USER_AGENT'] ) : '';

    elseif (stristr($navigator_user_agent, "msie 4"))
    {
        $browser = 'msie4';
        $dom_browser = false;
    }

    elseif (stristr($navigator_user_agent, "msie"))
    {
        $browser = 'msie';
        $dom_browser = true;
    }

    elseif (stristr($navigator_user_agent, "mozilla/4"))
    {
        $browser = 'ns4';
        $dom_browser = false;
    }

    else
    {
        $dom_browser = false;
        $browser = false;
    }

    // return the test result you want
    if ( $which_test == 'browser' )
    {
        return $browser;
    }
    elseif ( $which_test == 'dom' )
    {
        return $dom_browser;
        //  note: $dom_browser is a boolean value, true/false, so you can just test if
        // it's true or not.
    }
}

//Redirection
$this_browser = browser_detection('browser');

if($this_browser = 'ns4'){
   header("Location: forum/index.php");
   exit();
} else {
   echo '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
    <head>
    </head>
    <body>
        <center>
            <h1>Your browser does not support this site</h1>
        </center>
    </body>
</html>';

?>

Although from the conversation I am having with mxweb off the site, his concer is more css related then actualy browser support, in which he would have to create another set of css that goes with the browser that a person is using.

So you need to include in the php css link as well as the browser type, what I suggest is go to pixel2life.com and then search redirect in php and they have some scripts that do what your asking in your post.

I see. Third-party scripts are more preferred as they have been tested many times and continuous maybe available.

Well ~Happy Coding.

MXweb (and Others, too),

One way to handle the IE css problems is to create a second css file and use this sample of HTML to direct the user's Browser to implement the second CSS file if they are in fact using IE. I find it simpler to do this than to have a whole whack of hacks for the different IE (and other) Browsers.
