In Joomla! 1.0.x it was possible to determine if the user was viewing the front page by using code like this:

<?php
if ($option == 'com_frontpage' || $option == '') {
	echo 'This is the front page';
}
?>

== Joomla 1.5 ==

But in Joomla! 1.5.x the com_frontpage component is no longer present. This is how to achieve the same result in Joomla! 1.5.x

<?php
$menu = & JSite::getMenu();
if ($menu->getActive() == $menu->getDefault()) {
	echo 'This is the front page';
}
?>

This works by checking to see if the current active menu item is the default one.

== Joomla 1.6 and 1.7 ==

The same code that worked in Joomla 1.5 will work in 1.6 onwards. However, since PHP 5 is now a minimum requirement for Joomla 1.6 the ampersand (&) is no longer required on the first line. Use the following code for a site where all content is in the same language:

<?php
$menu = JSite::getMenu();
if ($menu->getActive() == $menu->getDefault()) {
	echo 'This is the front page';
}
?>

For multi-lingual sites the front page is dependent on the currently selected language, so you will need to use code like this:

<?php
$menu = JSite::getMenu();
if ($menu->getActive() == $menu->getDefault( 'en-GB' )) {
	echo 'This is the front page';
}
elseif ($menu->getActive() == $menu->getDefault( 'fr-FR' )) {
	echo 'Accueil';
}
?>

For multi-lingual sites, it could also be necessary to display a specific code/html for all Default Home pages.

<?php $menu = JSite::getMenu(); ?>
<?php $lang = JFactory::getLanguage(); ?>
<?php if ($menu->getActive() == $menu->getDefault($lang->getTag())) : ?>
etc.
