Help req. with Browser Sniffer Script

**Indyan** · 07-25-2006, 07:27 AM

I was trying to implement the Browser Sniffer Script, but I cant get it to work correctly.

http://pallab.frihost.net/sniff.php

sniff.php

Code:

<?php

include("headercustom.php");



if (ie) {
echo("This is for ie ");
}
else {
echo("This is for Opera");
}

include("footer.php");
?>

headercustom.php

Code:

<html>
<head>
  <title>Sniff</title>
  
<script type="text/javascript">

//CS1.1

var exclude=1;
var agt=navigator.userAgent.toLowerCase();
var win=0;var mac=0;var lin=1;
if(agt.indexOf('win')!=-1){win=1;lin=0;}
if(agt.indexOf('mac')!=-1){mac=1;lin=0;}
var lnx=0;if(lin){lnx=1;}
var ice=0;
var ie=0;var ie4=0;var ie5=0;var ie6=0;var com=0;var dcm;
var op5=0;var op6=0;var op7=0;
var ns4=0;var ns6=0;var ns7=0;var mz7=0;var kde=0;var saf=0;
if(typeof navigator.vendor!="undefined" && navigator.vendor=="KDE"){
	var thisKDE=agt;
	var splitKDE=thisKDE.split("konqueror/");
	var aKDE=splitKDE[1].split("; ");
	var KDEn=parseFloat(aKDE[0]);
	if(KDEn>=2.2){
		kde=1;
		ns6=1;
		exclude=0;
		}
	}
else if(agt.indexOf('webtv')!=-1){exclude=1;}
else if(typeof window.opera!="undefined"){
	exclude=0;
	if(/opera[\/ ][5]/.test(agt)){op5=1;}
	if(/opera[\/ ][6]/.test(agt)){op6=1;}
	if(/opera[\/ ][7-9]/.test(agt)){op7=1;}
	}
else if(typeof document.all!="undefined"&&!kde){
	exclude=0;
	ie=1;
	if(typeof document.getElementById!="undefined"){
		ie5=1;
		if(agt.indexOf("msie 6")!=-1){
			ie6=1;
			dcm=document.compatMode;
			if(dcm!="BackCompat"){com=1;}
			}
		}
	else{ie4=1;}
	}
else if(typeof document.getElementById!="undefined"){
	exclude=0;
	if(agt.indexOf("netscape/6")!=-1||agt.indexOf("netscape6")!=-1){ns6=1;}
	else if(agt.indexOf("netscape/7")!=-1||agt.indexOf("netscape7")!=-1){ns6=1;ns7=1;}
	else if(agt.indexOf("gecko")!=-1){ns6=1;mz7=1;}
	if(agt.indexOf("safari")!=-1 || (typeof document.childNodes!="undefined" && typeof document.all=="undefined" && typeof navigator.taintEnabled=="undefined")){mz7=0;ns6=1;saf=1;}
	}
else if((agt.indexOf('mozilla')!=-1)&&(parseInt(navigator.appVersion)>=4)){
	exclude=0;
	ns4=1;
	if(typeof navigator.mimeTypes['*']=="undefined"){
		exclude=1;
		ns4=0;
		}
	}
if(agt.indexOf('escape')!=-1){exclude=1;ns4=0;}
if(typeof navigator.__ice_version!="undefined"){exclude=1;ie4=0;}

</script>
</head>
<body>

footer.php

Code:

<br />
This is footer

</body>
</html>

What am I doing wrong?
Please Help.
Thanks

You're serious, aren't you?

sniff.php is using PHP, but headercustom.php is a Javascript script. The two don't mix like that.

I am a total novice. So I dont have much of an idea about what I am doing.

I am not sure why you say it should work this way

I checked the source, after my browser has rendered it. This is what it looks like.

Code:

<html>
<head>
  <title>Sniff</title>
  
<script type="text/javascript">

//CS1.1

var exclude=1;
var agt=navigator.userAgent.toLowerCase();
var win=0;var mac=0;var lin=1;
if(agt.indexOf('win')!=-1){win=1;lin=0;}
if(agt.indexOf('mac')!=-1){mac=1;lin=0;}
var lnx=0;if(lin){lnx=1;}
var ice=0;
var ie=0;var ie4=0;var ie5=0;var ie6=0;var com=0;var dcm;
var op5=0;var op6=0;var op7=0;
var ns4=0;var ns6=0;var ns7=0;var mz7=0;var kde=0;var saf=0;
if(typeof navigator.vendor!="undefined" && navigator.vendor=="KDE"){
	var thisKDE=agt;
	var splitKDE=thisKDE.split("konqueror/");
	var aKDE=splitKDE[1].split("; ");
	var KDEn=parseFloat(aKDE[0]);
	if(KDEn>=2.2){
		kde=1;
		ns6=1;
		exclude=0;
		}
	}
else if(agt.indexOf('webtv')!=-1){exclude=1;}
else if(typeof window.opera!="undefined"){
	exclude=0;
	if(/opera[\/ ][5]/.test(agt)){op5=1;}
	if(/opera[\/ ][6]/.test(agt)){op6=1;}
	if(/opera[\/ ][7-9]/.test(agt)){op7=1;}
	}
else if(typeof document.all!="undefined"&&!kde){
	exclude=0;
	ie=1;
	if(typeof document.getElementById!="undefined"){
		ie5=1;
		if(agt.indexOf("msie 6")!=-1){
			ie6=1;
			dcm=document.compatMode;
			if(dcm!="BackCompat"){com=1;}
			}
		}
	else{ie4=1;}
	}
else if(typeof document.getElementById!="undefined"){
	exclude=0;
	if(agt.indexOf("netscape/6")!=-1||agt.indexOf("netscape6")!=-1){ns6=1;}
	else if(agt.indexOf("netscape/7")!=-1||agt.indexOf("netscape7")!=-1){ns6=1;ns7=1;}
	else if(agt.indexOf("gecko")!=-1){ns6=1;mz7=1;}
	if(agt.indexOf("safari")!=-1 || (typeof document.childNodes!="undefined" && typeof document.all=="undefined" && typeof navigator.taintEnabled=="undefined")){mz7=0;ns6=1;saf=1;}
	}
else if((agt.indexOf('mozilla')!=-1)&&(parseInt(navigator.appVersion)>=4)){
	exclude=0;
	ns4=1;
	if(typeof navigator.mimeTypes['*']=="undefined"){
		exclude=1;
		ns4=0;
		}
	}
if(agt.indexOf('escape')!=-1){exclude=1;ns4=0;}
if(typeof navigator.__ice_version!="undefined"){exclude=1;ie4=0;}

</script>
</head>
<body>This is for ie <br />
This is footer

</body>
</html>

So, it reads it allright.
I have done it on another thing previously. It did work out.

I know. Thats why I created this thread.
What I meant was that, the script is getting loaded properly unlike what Twey suggested (Check the header section).

Any suggetion as how I should implement this/ why it isnt working?
I have doubts about the if-else condition I have put in.

Any suggetion as how I should implement this

i wasn't gonna say anything but since u asked

HTML Code:

<script type="text/javascript" src="sniffer.js"></script>
<script>
if(ie)
document.write("this is for ie")
else
document.write("this is for opera")
</script>

i think this should work

scrap the idea of changing the sniffer script(s) to PHP

**Twey** · 07-25-2006, 02:53 PM

Both scripts are running fine. But they don't interact, so when you try to call the Javascript function from PHP, nothing happens. The Javascript is just text at the point at which the PHP is being executed.

The model is thus:

PHP is executed. Output of PHP and the unparsed HTML (and Javascript) is sent to the browser.
Browser executes Javascript.
Browser displays final output of both.

For example, if we have the code:

Code:

<?php
  echo('<script type="text/javascript">document.write("<b>Hello!</b>");</script>');
?>

The server sees:

Code:

<?php
  echo('<script type="text/javascript">document.write("<b>Hello!</b>");</script>');
?>

Then the PHP parser is called and the output sent, and the browser sees:

Code:

<script type="text/javascript">document.write("<b>Hello!</b>");</script>

Then the browser parses the Javascript, resulting in the HTML:

Code:

<b>Hello!</b>

Then the browser renders that HTML, and the user sees:

Code:

Hello!
