cnj_excerpt_logic
Here is a simple plugin that allows logic if the excerpt is empty or if it is not empty. How to use the code, and an example of how I use it is part of the plugin help. Basically if I have a long post I put the short front page part in the excerpt and then continue the article in the body, but if it is a short entry I just use the body of the article, this plugin enables my form to display just the excerpt or the body depending on if the excerpt has content.

some help from wonderful, incredible persons Remillard and ubernostrum gave me the following solution:
in place of the current cnj_excerpt_logic plugin text, have this:
function cnj_if_excerpt($atts, $thing) {
global $thisarticle;
if(preg_match(’/\S/’, $thisarticle[‘excerpt’])) {
return parse($thing);
} else {
return;
}
}
function cnj_if_not_excerpt($atts, $thing) {
global $thisarticle;
if(!preg_match(’/\S/’, $thisarticle[‘excerpt’])) {
return parse($thing);
} else {
return;
}
}
Sadly, I think that this may be a very well written plugin—with very poorly written descriptions.
Can anyone break this down for me?
I’m hoping this simply will look at a post, and if it is long, put a shortened version of the post in the excerpt – for me.
OR maybe it will notice if you wrote an excerpt – add a “continue reading” but if not—no need.
I guess I don’t know EXACTLY what “allows logic if the excerpt is empty or if it is not empty” means.
<txp:cnj_if_excerpt>tag into a form, then anything between the opening and closing<txp:cnj_if_excerpt>tags will only show up when the article has an excerpt. Similarly, anything between pening and closing<txp:cnj_if_not_excerpt>tags will only show up if there isn’t an excerpt.There isn’t anything here which would automatically output a link of any kind; to get what you want, try this in your article list form:
<txp:cnj_if_excerpt><p><txp:excerpt /></p><p><txp:permlink>Read More...</txp:permlink></p></txp:cnj_if_excerpt>This is one of my favorite plugins…
