You want:
echo("<p>" . $text->truncate($thisstory['Story']['plot']) . "</p>");
FWIW, I wrote a function just last night that acts the same as
Text::truncate() but for HTML content. There are a couple of problems
with using the Text method on HTML content:
1) It will count the characters of your tags as part of the text
length to limit to. My function takes these into consideration, so the
limit you pass will be honoured.
2) It will inevitably leave you with an unbalanced HTML snippet. So,
an unclosed <strong> will ruin the rest of your page. My function
relies on the Tidy extension to clean up. If Tidy isn't available, it
passes the string to Text::truncate().
I found and fixed a couple of bugs this morning but there's still one
(that I know of) left. I'll post it later when I get a chance to have
another look at it. Although, I was planning to turn the function into
a Helper first. Maybe I'll do that.
I'll also post easy instructions for installing libtidy and the Tidy ext.
