Description
Just an idea how to display a random image out of any folders under the gallery root.
I hacked the brilliant_gallery.module starting at line 509:
if ( $thisfolder <> '' ) {
if ( $thisfolder == '?' ) {
$folders = array();
$dir = realpath(file_directory_path() . '/' . $galleryfolder);
$files = scandir($dir);
foreach ($files as $file) {
$currentfile = $dir . "/" . $file;
if (is_dir($currentfile)) {
if ($file != '.' && $file != '..') {
$folders[] = $file;
}
}
}
shuffle($folders);
$galleryfolder .= '/' . $folders[0];
}
else {
$galleryfolder .= '/' . $thisfolder;
}
}This piece of code chooses a random directory if "?" is set as gallery folder.
Thus, with the following line of code you realise displaying a random image:
[bg|?|1|100|random|1||1|]Maybe someone finds this useful and adds it to a future version.

thanks - I was thinking of doing something like this. Works great.

Im no coder so I probably have no business messing with such things but I have been looking for something like this for a while. Can you please give me a bit more detailed instructions on this? I have tried several different things with the code above and keep getting syntax errors whenever I put in the BG line. Im sure its something simple. Here is the latest one I tried.. (Dont laugh :) )
<?phpif ( $thisfolder <> '' ) {
if ( $thisfolder == 'files' ) {
$folders = array();
$dir = realpath(file_directory_path() . '/' . $galleryfolder);
$files = scandir($dir);
foreach ($files as $file) {
$currentfile = $dir . "/" . $file;
if (is_dir($currentfile)) {
if ($file != '.' && $file != '..') {
$folders[] = $file;
}
}
}
shuffle($folders);
$galleryfolder .= '/' . $folders[0];
}
else {
$galleryfolder .= '/' . $thisfolder;
}
}
[bg|?|1|100|random|1||1|]
?>

This could be a very useful feature, choosing random images from random subdirectory.
I updated Satanclaus' code for current stable and dev version. In brilliant_gallery.module
if ( $thisfolder <> '') {if ($galleryfolder <> '') {
#$galleryfolder .= '/' . $thisfolder;
$galleryfolder .= (substr($thisfolder, 0, 1) == '/' ? '' : '/') . $thisfolder; // See http://drupal.org/node/176939#comment-1494648
}
else{
$galleryfolder = $thisfolder;
}
}
was changed to
if ( $thisfolder <> '') {if ($galleryfolder <> '') {
if ( $thisfolder == '?' ) {
$folders = array();
$dir = realpath(file_directory_path() . '/' . $galleryfolder);
$files = scandir($dir);
foreach ($files as $file) {
$currentfile = $dir . "/" . $file;
if (is_dir($currentfile)) {
if ($file != '.' && $file != '..') {
$folders[] = $file;
}
}
}
shuffle($folders);
$galleryfolder .= '/' . $folders[0];
}
else {
#$galleryfolder .= '/' . $thisfolder;
$galleryfolder .= (substr($thisfolder, 0, 1) == '/' ? '' : '/') . $thisfolder; // See http://drupal.org/node/176939#comment-1494648
}
}
else{
$galleryfolder = $thisfolder;
}
}
This way entering "?" as gallery name in a bg tag it will choose a random subdirectory.
Can you please check it and add to future release if you also find it useful...

One more idea:
The above code only scans the default brilliant gallery folder for subdirectories. If Picasa cached dirs are used, that folder should also be scanned for directories...
