This file is included when the module is acutally loaded.
<?php
defined( '_VALID_MOS' ) or die( 'Direct Access to this location is not allowed.' );
With any PHP source code in Mambo, it is necessary to make sure the code is actually running within Mambo. This enhances security.
global $mosConfig_live_site;
This pulls the current site's url from Mambo's configuration file. It will be used below for building a link to the currently selected RSS feed.
$shortmessage = $params->get( 'shortmessage' );
$button = $params->get( 'button' );
$moduleclass_sfx = $params->get( 'moduleclass_sfx', '' );
$feed = $params->get( 'feed', 'RSS 0.91' );
Parameters defined in the XML file and set by the administrator are extracted into appropriate variables.
$feedurl = "";
switch( $feed )
{
case "RSS 0.91":
$feedurl = $mosConfig_live_site . '/index2.php?option=com_rss&feed=RSS0.91&no_html=1';
break;
case "RSS 1.0":
$feedurl = $mosConfig_live_site . '/index2.php?option=com_rss&feed=RSS1.0&no_html=1';
break;
case "RSS 2.0":
$feedurl = $mosConfig_live_site . '/index2.php?option=com_rss&feed=RSS2.0&no_html=1';
break;
case "Atom":
$feedurl = $mosConfig_live_site . '/index2.php?option=com_rss&feed=ATOM0.3&no_html=1';
break;
default:
$feedurl = $mosConfig_live_site . '/index2.php?option=com_rss&feed=RSS0.91&no_html=1';
break;
}
Taking the value of the feed parameter and the site url, an apppropriate link is built. This link will be sent to My Yahoo! when the button is clicked.
$buttoncode = "";
switch( $button )
{
case "short":
$buttoncode = '<img src="http://us.i1.yimg.com/us.yimg.com/i/us/my/addtomyyahoo6.gif" width="89" height="33" border="0">';
break;
case "long":
$buttoncode = '<img src="http://us.i1.yimg.com/us.yimg.com/i/us/my/addtomyyahoo4.gif" width="91" height="17" border="0">';
break;
default:
$buttoncode = '<img src="http://us.i1.yimg.com/us.yimg.com/i/us/my/addtomyyahoo4.gif" width="91" height="17" border="0">';
break;
}
Based on the chosen button, a link to the correct image on Yahoo's servers is built.
?>
<div class="myyahoo<?php echo $moduleclass_sfx;?>">
A styled 'div' is generated using a custom class.
<?php
if($shortmessage)
{
echo '<div align="center" class="myyahoo_text' . $moduleclass_sfx . '">' . $shortmessage . '</div>';
}
When the administrator adds a short message through the appropriate parameter in the backend, it is displayed here.
?>
<div align="center">
<a href="<?php echo 'http://add.my.yahoo.com/rss?url=' . $feedurl; ?>">
<?php echo $buttoncode ?>
</a>
</div>
A nested 'div' centers the previously built button and the complete Add to My Yahoo! link is generated. When a visitor clicks this link, they are taken to My Yahoo! and guided through adding the newsfeed to their page. If they do not have a Yahoo! account, they will be prompted to create one.
</div>
Finishes the 'div' with an optional styled class.
