[snippet] RandomBackgroundImage everywhere

added png
the snippet is

$folder = ’images’;

$i = 0;
$imgDir = opendir ($folder);
while ( $file = readdir( $imgDir ) )
{
//checks that file is an image
$file_type = strrchr( $file, "." );
$is_image = eregi( "jpg|gif|png",$file_type );

if ( $file != ’.’ && $file != ’..’ && $is_image )
{ $images[$i++] = $file; }
}
closedir ($imgDir);

srand( (double) microtime()*1000000 );
$image_name = $folder . ’/’ . $images[rand( 0,sizeof( $images ) -1 )];

//ends script if no images found
if ( $i == 0 )
die();

return "background=’$image_name’" ;

usage
put the call to the snippet in the table, div or background into the <>
example
<td width="30%" height="100%" valign="top" [[RandomImage]] bgcolor="#F4F4F4">content</td>
put [! !] if you want to update on browser reload (dont tested i dont want it)
change the folder to the direction of your image folder

$is_image = eregi( "jpg|gif",$file_type );

Is it posible to add a chek to see if the image is not a thumb? fck editor generates thubs in the same folder.
somthines i like to set the image my self using fckeditor but then the random image snippet also display’s those .thumb_ files.
my PHP knowledge is not so good that i can do that, but i think it ist not to hard to do somthing like if .thumb_* then do not put in array but how to translate my sessemistreet language into php.

hope that somone can help me.

Hi Dimmy,

The easiest way I can think to exclude the thumb images is to check the filename against a regexp for ’.thumb*’. If you can change this line of code:



for:



that should work.

I’ve tested it quickly and seems to do the job but you’ll have to let me know if you have any problems.

Cheers, Garry

You can kill three birds with one regexp if you just exclude all files that begin with a .

Thanks a lot this works great
