How to hack in the banner component to display flash banners

Recently I needed to add flash banner support to one of my client's sites. I've tried out various banner components wich promised easy flash support, but all of them failed for various reasons (from code flaws to z-index problems - template incompatibility, etc.). In the last moments, just before being forced to crop up a new one

I found this little hack by Fotis Evangelou. Seems to be all over the net... Thanks for sharing!!!

The default banners component that ships with Joomla, does not natively support flash, I guess for various reasons, but one being that "hey, what the community is for?"...

So I decided to hack the standard com_banners component to get flash banners working as normal images would. Follow the instructions carefully, it's not difficult. Each step responds to a different file that needs to be changed (three files in all) and all you have to do is just copy - paste!

1. administrator/components/com_banners/admin.banners.html.php at about line 275, change this:
Code:

if (eregi("swf", $_row->imageurl)) {
?>
<img src="images/blank.png" name="imagelib">
<?php

to this:
Code:

if (eregi("swf", $_row->imageurl)) {
$imageurl 	= "../images/banners/".$_row->imageurl;
$getflashinfo = @getimagesize( $imageurl );
echo '<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" 
codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0" 
width="'.$getflashinfo[0].'" height="'.$getflashinfo[1].'">
<param name="movie" value="'.$imageurl.'" />
<param name="quality" value="high" />
<param name="wmode" value="transparent" />
<embed src="'.$imageurl.'" quality="high" wmode="transparent" 
pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash" 
width="'.$getflashinfo[0].'" height="'.$getflashinfo[1].'"></embed>
</object>';

2. modules/mod_banners.php

at about line 85 change this:
Code:

} else if (eregi("\.swf$", $banner->imageurl)) {
$imageurl 	= "$mosConfig_live_site/images/banners/".$banner->imageurl;
echo "<object classid=\"clsid:D27CDB6E-AE6D-11cf-96B8-444553540000\" 
codebase=\"http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,0,0\" 
border=\"5\">
<param name=\"movie\" value=\"$imageurl\"><embed src=\"$imageurl\" loop=\"false\" 
pluginspage=\"http://www.macromedia.com/go/get/flashplayer\" 
type=\"application/x-shockwave-flash\">
</embed></object>";

to this (if you want the link specified in the admin to be on top of your flash banner):
Code:

} else if (eregi("\.swf$", $banner->imageurl)) {
$imageurl 	= "$mosConfig_live_site/images/banners/".$banner->imageurl;
$link		= sefRelToAbs( 'index.php?option=com_banners&task=click&bid='. $banner->bid );
$getflashinfo = @getimagesize( $imageurl );
echo '
<a href="'.$link.'" target="_blank" style="display:block;position:absolute;
width:'.$getflashinfo[0].'px;height:'.$getflashinfo[1].'px;z-index:999;"></a>
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" 
codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0" 
width="'.$getflashinfo[0].'" height="'.$getflashinfo[1].'" style="position:relative;z-index:0;">
<param name="movie" value="'.$imageurl.'" />
<param name="quality" value="high" />
<param name="wmode" value="transparent" />
<embed src="'.$imageurl.'" quality="high" wmode="transparent" 
pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash" 
width="'.$getflashinfo[0].'" height="'.$getflashinfo[1].'" style="position:relative;z-index:1;">
</embed>
</object>';

or to this (if you don't want any link on top of your flash banner, which seems logical since almost all commercial flash banners already link to somewhere):

Code:

} else if (eregi("\.swf$", $banner->imageurl)) {
$imageurl 	= "$mosConfig_live_site/images/banners/".$banner->imageurl;
$getflashinfo = @getimagesize( $imageurl );
echo '
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" 
codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0" 
width="'.$getflashinfo[0].'" height="'.$getflashinfo[1].'" style="position:relative;z-index:0;">
<param name="movie" value="'.$imageurl.'" />
<param name="quality" value="high" />
<param name="wmode" value="transparent" />
<embed src="'.$imageurl.'" quality="high" wmode="transparent" 
pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash" 
width="'.$getflashinfo[0].'" height="'.$getflashinfo[1].'"></embed>
</object>';

3. includes/joomla.php

inside function images, commented in the file as:
Code:

/**
* build the select list to choose an image
*/
function Images

and below that, at about line 4826, change this:
Code:

if ( eregi( "bmp|gif|jpg|png", $file ) ) {

to this
Code:

if ( eregi( "bmp|gif|jpg|png|swf", $file ) ) {

Here we added swf support for the file browser inside the banners component admin.
Conclusion

By simply copy-pasting three blocks of code we managed to give the standard joomla distro support for flash banners.
It wasn't difficult now, was it?

Thanks again, Fotis!
