Gives you full control over the WordPress excerpt: change the length, the ellipsis [...] and surrounding markup.
Yes, it does.
If you want to leave HTML in, then the "more" tag is your friend. the_excerpt is meant to remove HTML.
You can manually call the function like this: <?php echo better_excerpt($length, $ellipsis, $before_text, $after_text, $link_to_post, $link_text); ?> for example <?php echo better_excerpt(500, '...', '
' '1', 'read more'); ?> obviously replacing the variables with your own values. The value of link_to_post should be 'yes' or 'no'. All variables need to have values, so if you don't want any - e.g. - code before or after the extract, you need empty inverted commas ''
No, it doesn't: half-words are trimmed back to the end of the previous word.
Length is set in characters - that is, letters, numbers, spaces and bits of punctuation. We do it like this because some people use lots of long words, and some people don't, so a ten word excerpt for some would be the same length as a twenty word excerpt for others. As a general rule of thumb, assume 5 letters in the average English word.
This plugin requires PHP5. Most likely, you're still running PHP4. It's time to upgrade.
