As long as you don't use any fancy things like lists, quotes, or similar at the beginning of your post, we can handle this with some additional code. Otherwise you are right with using a manual excerpt.

I really appreciate your help. Yes, that is what I am going for. Very similar to the standard excerpt except that it doesn't cut off in the middle of a sentence with ... I guess the easiest answer is to always write custom excerpts and that is probably a good practice anyway.

And it should have the 'sentence' functionality? helgatheviking on "Set the excerpt length by sentence" http://themeshaper.com/forums/topic/set-the-excerpt-length-by-sentence#post-12266 Mon, 10 May 2010 15:27:46 +0000 helgatheviking 12266@http://themeshaper.com/forums/ Hi Chris, Thank you for your effort! What you have written seems to exactly replicate the FancyExcerpt plugin.. and the images are still included in the excerpt instead of being escaped. Am I supposed to have the fancyexcerpt plugin enabled? I tried that and it produced a fatal error.

Would add a few filters to control 'escaping' and 'number of sentences'. This could be integrated in your child theme.

Fancy Excerpt is definitely the closest- b/c of the sentence-awareness - but I don't want it escaping images and other things that end up looking goofy w/ thumbnails, and there is no way to toggle that on/off like in Advanced Excerpts. If they could get together and have a child called Advanced Fancy Excerpt that would be brilliant.

I've seen the snippets for setting length based on words, but was wondering if it wouldn't be too hard to extrapolate out to sentences... which seems more logical to me.
