Is it possible to have a merge tag inside a merge tag? I'm trying to use the value of a radio button the user selects to pull a specific piece of information from a lookup table of custom fields attached to the post the form is on.
Like so: {custom_field:{size:6}}
but it doesn't seem to work. It works if i manually enter the value in as a test of the custom field like so: {custom_field:3x8}
So i know it can successfully find the value from the custom field of that post. Maybe it is just not possible to do recursive merge tags?
What would an alternative solution be in that case? is there a filter i could use perhaps?
I took a look at the docs, but none of the filters really seemed like they fit the job. Is there a way to compute a merge tag from php?
Thanks,
