I'm using the following excerpt filter but it limits the post length by words. How can I put a limit on characters? Like Twitter. I can;t find any documentation in Codex.
function new_excerpt_length($length) {
return 20;
}
add_filter('excerpt_length', 'new_excerpt_length');

Nem,
Looks like you need a custom function
function get_the_twitter_excerpt(){
$excerpt = get_the_content();
$excerpt = strip_shortcodes($excerpt);
$excerpt = strip_tags($excerpt);
$the_str = substr($excerpt, 0, 20);
return $the_str;
}you should be able to put the above into your functions and this
<?php echo 'Excerpt: '.get_the_twitter_excerpt(); ?>
into your loop.

Brilliant! This works very nicely. Thanks jakep!

Mate I've found a simpler method in an old theme I made.
<?php echo substr(get_the_excerpt(), 0,30); ?>
It does the same thing.

php has so many ways..

this is great but do you know how I would end with a full word?
Posted 1 year ago #
Add this to the function -
$the_str = substr($excerpt, 0, 20);
$the_str = trim(preg_replace( '/\s+/', ' ', $the_str));
return $the_str;boom!

Even better -
function get_the_popular_excerpt(){
$excerpt = get_the_content();
$excerpt = preg_replace(" (\[.*?\])",'',$excerpt);
$excerpt = strip_shortcodes($excerpt);
$excerpt = strip_tags($excerpt);
$excerpt = substr($excerpt, 0, 40);
$excerpt = substr($excerpt, 0, strripos($excerpt, " "));
$excerpt = trim(preg_replace( '/\s+/', ' ', $excerpt));
$excerpt = $excerpt.'... <a href="'.$permalink.'">more</a>';
return $excerpt;
}

@seanjacob
Can you explain how to use your function ?
Thanks,

In functions.php add
function get_excerpt(){
$excerpt = get_the_content();
$excerpt = preg_replace(" (\[.*?\])",'',$excerpt);
$excerpt = strip_shortcodes($excerpt);
$excerpt = strip_tags($excerpt);
$excerpt = substr($excerpt, 0, 40);
$excerpt = substr($excerpt, 0, strripos($excerpt, " "));
$excerpt = trim(preg_replace( '/\s+/', ' ', $excerpt));
$excerpt = $excerpt.'... <a href="'.$permalink.'">more</a>';
return $excerpt;
}Change the value 40 to how many characters you want to display. And also 'more' to what text you want to display.
Then call your function in index.php or where ever your planning on getting your posts.
<?php echo get_excerpt(); ?>

Thank you for your answer.
I've tried this : http://bavotasan.com/tutorials/limiting-the-number-of-words-in-your-excerpt-or-content-in-wordpress/
and it did the job, I can ajust the excerpt length how I want with
<?php echo excerpt(25); ?>
And the last word of the excerpt isn't truncated :)

Glad you found a solution. My code doesn't truncate the last word either and with my problem I needed it to be by characters not words.

seanjacob - this is very useful, thank you.
Can you tell me how i auto-wrap the excerpt in <p></p> tags? Like the_excerpt() does?
Posted 10 months ago #
$excerpt = $excerpt.'... <a href="'.$permalink.'">more</a>';
Replace this line in my code with -
$excerpt = '<p>'.$excerpt.'... <a href="'.$permalink.'">more</a></p>';
Posted 10 months ago #
Or use this to return the excerpt in a paragraph:
return apply_filters('the_content', $excerpt);

seanjacob, no matter what number I set, your script will not display more than 64 characters.

It seems like ".$permalink." is calling the actual url of the page where i'm at, and not the page of the single post.
Is it only me? When i click "more" the page just reloads.
Posted 6 months ago #
$permalink = get_permalink($post->ID);
Try adding this to the top of the function.
Posted 6 months ago #
Use this function if you're planning on using it more than once with a different amount of characters.
function get_excerpt($count){
$permalink = get_permalink($post->ID);
$excerpt = get_the_content();
$excerpt = strip_tags($excerpt);
$excerpt = substr($excerpt, 0, $count);
$excerpt = substr($excerpt, 0, strripos($excerpt, " "));
$excerpt = $excerpt.'... <a href="'.$permalink.'">more</a>';
return $excerpt;
}Call the function plus the amount of characters -
<?php echo get_excerpt(125); ?>

Been trying to figure this out: Is there a way to use this code, creating a character limit, without truncating the last word? (I would still want the read more ellipses.)
Any help would be appreciated!
Posted 6 months ago #
Without the truncating -
function get_excerpt($count){
$permalink = get_permalink($post->ID);
$excerpt = get_the_content();
$excerpt = strip_tags($excerpt);
$excerpt = substr($excerpt, 0, $count);
$excerpt = $excerpt.'... <a href="'.$permalink.'">more</a>';
return $excerpt;
}
