I just ran across this plugin tonight. It's quite awesome. After reading a few of the remarks from others here, this need to be in the base code. It's seriously kickass.
I also use the Genesis Simple Edits plugin. Between the two of them - man, it's some serious power without touching a template. Gotta love that.
Anyway, I was running into an issue tonight in trying to implement a code. The problem is the custom field I'm using. It's a URL, and as such, the custom field code I"m trying to construct needs quotes, but that makes the plugin not work right.
Basically, here's what I constructed, but it doesn't work right for obvious reasons.
[custom_field field="MLBURL" this_post="1" limit="0" before=" | <a href="" after="" target="_blank">MLB.com Recap</a>" between=", " /]
There any way around this?
