I’m using the excerpt field on my blog in addition to the “more” tag. The front page shows each post up to the “more” tag with a “read more” button, but I use the excerpt field to store the author’s synopsis of the article. The only place I want to display the excerpt is on the actual post page, in a text widget. Naively, I thought I could just call the_excerpt() or get_the_excerpt() in the text widget.
Boy was I wrong.
After a crash course in the loop, I now understand why that wouldn’t work. I’ve found a lot of tutorials showing how to add a function and then call that function from the widget in order to get things that are “inside” the loop such as the excerpt. Unfortunately, I need to pass the post ID to the function, and my text widget doesn’t seem to know how to deal with the post->ID. In other words, if I put in
<?php get_excerpt_outside(post->ID); ?>
the widget will output
(And that’s assuming I’ve even written the function correctly.)
I know I’m clueless and don’t have any business attempting this on my own, but I can’t find a simple plugin to accomplish it. Can anyone offer any advice?
