The first answer from whooami actually helped me, because that was just what I was searching, to limit the characters not words. Except it did not work. After looking at bechster code and investigating a bit I came up with this:
<?php echo substr(get_the_excerpt(),0,XY); ?>
All that instead of <?php the_excerpt() ?> and for XY type the number of chars desired. Hope it’s helpfull to some other PHP noob like me.
Of course my code looks a bit different:
<?php
$content = get_the_content('',FALSE,'');
$content = apply_filters('the_content', $content);
$content = str_replace(']]>', ']]>', $content);
echo substr($content,0,262);
?>…
At the end of the last paragraph a none-linking … is inserted with the code …
. I have no idea why this works. Logic tells me it should appear outside the <p> tag. But it’s inside and it works (and validates), so it’s fine with me. I still would like to hear a logic answer if someone can offer one.
