Hello

This is the scenario,

I have K2 site, that has quite an amount of items

Just a recent requirement, i need to put some script inside of every items created

I was imagining a solution like below, or sort of..

a plugin that can insert automatically, any pre defined scrip/code/tag into k2 items, if can select by categories will be highly appreciated

Any ideas, or perhaps any existed solutions for this task?

Thanks

I would place this code in my overrides.
You can also check the item's category id (in the item.php file) and paste the appropriate snippet.
