It should be noted that there is a patch RTBC to increase performance for the tagadelic module: http://drupal.org/node/193057.

Probably a dumb question, but I have to ask it: ;)

In which file did you put the functions _phptemplate_variables and theme_tags? Is it page.tpl.php?

Thanks!

hai! thanks for article.

What you think about allocate some tags at tags cloud by put "ctrl"? It's very difficultly to realise?

I needed to do something very similar but I used some more of the stock Drupal tools.

I put these functions in a module with some other helper functions specific to my site.

The first thing I did was use to use the tagadelic module to define a custom tag cloud block.

function theme_mymodule_tag_cloud($vid = 1){
$tags = tagadelic_get_weighted_tags(array($vid),7,15);
$tags = tagadelic_sort_tags($tags);
$block = theme('tagadelic_weighted', $tags);//return a chunk of 12 tags
$block .= theme('tagadelic_more', $vid);//add more link
return $block;
}

But as you noted, the tagedelic module uses some really expensive queries that you don’t want to run on every page load.

So I also used the hook_cron, but instead, I used Drupal’s internal caching system. So this is all the code I had to write:

function mymodule_cron(){
cache_clear_all('mymodule', 'cache', TRUE);
cache_set('mymodule_tag_cloud', 'cache', serialize(theme(mymodule_tag_cloud)));
}

Then I created a function that retrieved the cached tag cloud and call it from a block using the php format option. Of course now it occurs to me, I could have just put this php in the block instead of having it exist as a function in my module. Or maybe, I just have just properly defined this as a block in the module using the block hooks.

function mymodule_cached_cloud(){
$cached = cache_get('custom_tag_cloud');
return unserialize($cached->data);
}

I have not looked in several months, but I think the tagedelic developers may be implementing some more caching in the module.

Thank you for the interesting writeup and details. One option to deal with performance is to use the block cache module (http://drupal.org/project/blockcache) to cache tagadelic (or any) blocks for registered users. Chris

Thank you for clarifying this. I wasn’t sure how to answer this question since I haven’t looked through tagadelic’s source. Couldn’t find time to do this. : )
