Identify the user's browser

Sometimes there arises a need to identify the user's browser.


It is pretty easy to find browser with jquery. So if you have included jquery in your page, it takes a simple line to identify the browser: 

if ($.browser.msie) {} // IE

if (($.browser.msie) && ($.browser.version == '6.0')) {} // IE6
if ($.browser.opera) {} // opera

if ($.browser.mozilla) {} // Firefox




With the help of php, you can get the browser 
details with the help of: 
$_SERVER['HTTP_USER_AGENT'];

Or you can even use the combined version of php and javascript.
php + javascript code:

<script type="text/javascript">
var string1 = "<?php echo $_SERVER['HTTP_USER_AGENT']; ?>"; // Browser string

var myRegExp1 = /Firefox/;
var matchPos1 = string1.search(myRegExp1);

var myRegExp2 = /Chrome/;
var matchPos2 = string1.search(myRegExp2);

var myRegExp3 = /MSIE/;
var matchPos3 = string1.search(myRegExp3);

if(matchPos1 != -1)
document.write("Firefox was found");

else if(matchPos2 != -1)
document.write("Chrome was found");

else if(matchPos3 != -1)
document.write("Internet Explorer was found");

else
document.write("Neither Firefox, IE or chrome was found");

</script>

Try this code in different browsers and see the difference. Enjoy :)

Joomla validate chrono forms using jquery

It is a common practice to use Chrono forms in our joomla site to setup various forms in the site, be it a contact us form, submit a ticket form, or whatever. I have set the option "validate form" to "No" under chronoform settings in admin panel, and also preferred to not include any js or css files. For validating the chrono forms, i prefer jquery. So first lets add jquery support in our joomla. It is quite simple: 1. Download jquery.js and jquery_min.js (1.4.2 version is enough) and place them in media/system/js folder of your joomla. 2. Edit libraries->joomla->html->html->behavior.php, and add the following function below the mootools() function: function jQuery($debug = null)     {         static $loaded;         global $mainframe;         // Only load once         if ($loaded) {    ...
