Hi guys,
To indicate in the block-file from which album the block must derive it's pictures, just add:

Code: › 'itemId'=>1234

to the block-code (1234 would have to correspond with the album code of choice)

so find the piece of code like:

Code: › list($ret,$html, $head) = GalleryEmbed::getImageBlock(array('blocks'=>$blockType,'show'=>$display,'itemFrame'=>'solid','albumFrame'=>'solid','maxSize' => $maxSize));

and replace it with something like:

Code: › list($ret,$html, $head) = GalleryEmbed::getImageBlock(array('blocks'=>$blockType,'show'=>$display,'itemId'=>1234,'itemFrame'=>'solid','albumFrame'=>'solid','maxSize' => $maxSize));

Remember to find out the itemId number of the album of your choice...

This method works fabulously Smile

Cheers,

actually, after hacking away at the selectable block file, i realized that since you want to hardcode in the values of albums, that the normal random block file is what you should use.

note that in the readcache function, you'll need the album name and the number of photos in the album (the randomizer uses the number of photos to determine how often to pull from that album).

this works for G2, but slackbladder is enquiring about G1 Smile

Hi Dari,

Does the 'hacked' block create / re-build the cache file (so new photo's when added to the album are also added to the cache i.e. the cache number increases)?

dari

no, this is a quick and dirty hack. it doesn't use a cache file at all, just an array that you populate with your albums by hand (i thought that's what you wanted)...however, updating the array with the proper values shouldn't be too hard...

slackbladder

What I am after (and have it working just about using the selectable block) is:

From the block code I can select (hard code) an album from which the random block pulls an image from.

I currently use a different 'cache' file for each album (e.g. album1-random.cache, album2-random.cache)

I need for the code to rebuild each seperate cache, using it's hardcoded album images.

The reason all this is that I have built a site (music) that has sections dedicated to different artists, each artist has a section the gallery for his photos.

Please review:

http://www.classicalx.com

then an artist page:

http://www.classicalx.com/Andrea_Bocelli.html

Random block is on the left.

Many thanks for the help Smile

I'm getting MySQL errors when attempting to use it with Gallery2. Confused

[edit] If this is only for Gallery1, is there a way to eliminate certain albums from displaying in the random photo block in G2?? [/edit]

Thanks!

Errors received:

Code: › Warning: main(/home/.alonso/xxxx/the152.com/modules/gallery2/init.php): failed to open stream: No such file or directory in /home/.alonso/xxxx/the152.com/NG-RandomPhotoSelectTest_functions.php on line 61

that block is only for g1. you can via album properties in g2, "hide" the album from imageblock.
