set option in product URL and hidden options

Hello,



I’d like to link to a product where one of the options is set in the URL. Let’s say I have a product called “tshirt” and I want to set option “size” to “large”. Is it possible to link to the product like /tshirt.html?size=large ?



Also, is there a way to create a hidden option, in particular a hidden text option?



Apologies if this double posts. For some reason I’m not getting a confirmation that this is posting.



Thanks,

Jack

The “Similar Threads” below helped a lot more than the terrible forum search, but came short of an answer.



Apparently the URL trick is only possible through some hackery, which is what I’m doing. The problem is the need to hard code things to make sure I put the info in the right option field.



As for the other question, I see that it’s possible to have a hidden feature, but those are static. I’m looking for a hidden option.



Thanks,

Jack
