Trying to modify browser sniffer??

[gham]

Hi folks,

 

I'm NOT a PHP coder but, usually, I can fiddle/reverse engineer a script to fit my purposes.  :-\

 

I tried to find a thread here that would allow me to decipher (by example) an open-source "browser sniffer" script (downloaded from Yootheme (dot) com) that notifies the user if his/her version of ie is old and provides links to "upgrade" to a more "contemporary" browser but... alas!... I may be over my head here... I'm hoping someone here might be willing to help.

 

I'm trying to modify the script to, instead of responding to (and displaying a notification dialogue with various browser download links) only ie 6, notify for ANY version of ie so that I can suggest alternative browsers. (I'd like to help users migrate AWAY from ie!)

 

Is it OK for me to post the code here so that someone might suggest the necessary changes?

Sure.  Just as a pointer though, I'd suggest learning the basics of PHP so this becomes easier for you.  But anyway, post the script.  If I think that it's coded poorly, I might rewrite it for you.  Idk why, I'm just feeling kinda giving today, lol.

<script type="text/javascript">
function detectBrowser(){
var browser=navigator.appName;
var b_version=navigator.appVersion;
var version=parseFloat(b_version);
if ((browser=="Microsoft Internet Explorer") && (version>=6))
  {
  }
else
  {
  alert("This website is best viewed with IEv6.");
  }
}
</script>

 

But thats javascript

Actually, the function already exists for you.  Yootheme uses the mootools javascript framework that does all of the browser tests for you.  So just use the following:

 

    * Browser.Engine.trident - (boolean) True if the current browser is Internet Explorer (any).

    * Browser.Engine.trident4 - (boolean) True if the current browser is Internet Explorer 6.

    * Browser.Engine.trident5 - (boolean) True if the current browser is Internet Explorer 7.

    * Browser.Engine.gecko - (boolean) True if the current browser is Mozilla/Gecko.

    * Browser.Engine.webkit - (boolean) True if the current browser is Safari/Konqueror.

    * Browser.Engine.webkit419 - (boolean) True if the current browser is Safari2/WebKit before version 419.

    * Browser.Engine.webkit420 - (boolean) True if the current browser is Safari3 (WebKit SVN Build)/WebKit after version 419.

    * Browser.Engine.presto - (boolean) True if the current browser is Opera.

    * Browser.Engine.presto925 - (boolean) True if the current browser is Opera before or equal version 9.25.

    * Browser.Engine.presto950 - (boolean) True if the current browser is Opera major or equal version 9.50.

    * Browser.Engine.name - (string) The name of the engine.

    * Browser.Plugins.Flash.version - (number) The major version of the flash plugin installed.

    * Browser.Plugins.Flash.build - (number) The build version of the flash plugin installed.

Thank you DarkWater and thesaleboat and CroNIX!!! Sorry about being offline for a bit... life's been demanding of late... good to KNOW who da man is!

 

I'm trying to make sense of CroNIX's suggestion/code... but I think I might be missing the point?! I can't figure out where in the Yootheme script (copied below) there's a call to Mootools framework other than drawing the AJAX notification window (ref. line #57).

 

Here's the script that I'm trying to work with (from Yootheme -- obviously written as a module/extension for Joomla! v1.0.X with hooks to a custom back-end admin CP):

		this.elementFx.start.pass([0,1], this.elementFx).delay(1500);

		this.elementFx.start(1,0);

});
window.addEvent('domready', function() { new YOOiecheck('yoo-iecheck'); });
}

</script>

 

I thought that I could simply modify line #24-29 (ie browser check) to identify ANY/ALL msie user agents and trigger the "upgrade" message but I'm lost as why, on in line #27 (if (!$is_ie7 && $is_ie6), the if statement includes ie6 AND ie7. I think I'm confused about the variables(?) within the if (array_key_exists... statement: I'm not understanding what's going on there.

 

I may be "denser" (more dense) than anybody realized here! BTW, DarkWater, I have been trying to self-teach myself PHP for awhile now... what's the best way/book/course in your opinion, to "learn the basics of PHP" (besides this venue: "leaching" your knowledge/expertise)?

 

Much thanx for your generosity/help, guys!
