Suggestion - add modifier contains to core smarty plugins
Posted: Wed Jun 10, 2009 10:23 pm
I found a great plugin for the smarty lib today that allows the modifier 'contains' for searching strings for a particular value - I used this to create a conditional statement to allow my news template to discern between pdf and docs and image files so it would create the correct link. I think the addition of this plugin to the core installation would be an asset.
I found this at http://www.phpinsider.com/smarty-forum/ ... hp?t=10384
posted by JasonDS and used joeri210's version (code below)

If you don't think this belongs in the core, how is the correct way to add this in without putting it in core directories?
