Can I see if a file exists in Liquid?

[FriscoTX]

Any way to test for existence of a specific file on the server in Liquid?

Basically, I want to do this:

if file_exists

  do this

else

  do that

endif

Thanks!

I don't think this is possible in liquid on the front end. You can do similar tricks and hacks with ajax, request a file, see if it returns 200 or 404, then you know it exists; however JS runs after the DOM has been loaded so this is not ideal for most front end situations.

I personally would like liquid to also test for the existence of a file, and also to give file dimensions (width, height).

Depends on exactly what you are referring too Bill.

If in regard to a field from say a webapp then it is != '' (not blank) as its basically a string.. But if you are referring to 404 not found file on an image path what Stephen says is correct but I would really not bother with those solutions or trying.

The only way would be if BC before it rendered media type fields to run a file exists check and report that back to us.

I do not know how that would be load wise for them and if they would consider doing that.
