I was wondering if there was any way I could define a string of text in a single place and insert it within posts with a single, short reference.
It’s a bit like the out of the box
Admin -> Customize -> Text Content, but for my own custom variables that can be inserted into posts.
My use case was adding a disclaimer for my affiliate links. As the number of affiliate links grew across many posts and Topics I noted that my disclaimers were proliferating along with them. I occasionally like to make improvements to the disclaimers and this gets more onerous as the number grows.
I’m also considering making my affiliate links more generic so I have one centrally managed link for each product link, for example, which appears multiple times. If that product link changes, I only have to change it in one place.
Obviously I might be able to do some kind of rails find & replace, but that’s not as clean/safe nor ‘online’.
So I wanted a place to define & maintain a text string in a single place and have changes immediately reflected everywhere that is used on next page view.
