Changing length of the_excerpt without changing it on the whole wordpress

can;t remember where i found this code. add the following to functions.php

function excerpt($num) {
$limit = $num+1;
$excerpt = explode(' ', get_the_excerpt(), $limit);
array_pop($excerpt);
$excerpt = implode(" ",$excerpt)."...";
echo $excerpt;
}

function content($num) {
$theContent = get_the_content();
$output = preg_replace('/<img[^>]+./','', $theContent);
$limit = $num+1;
$content = explode(' ', $output, $limit);
array_pop($content);
$content = implode(" ",$content)."...";
echo $content;
}

function title($num) {
$limit = $num+1;
$title = explode(' ', get_the_title(), $limit);
array_pop($excerpt);
$title = implode(" ",$title)."...";
echo $title;
}

then

<?php excerpt('25'); ?>
you can specify the length each time you use it

Hi.
Thanks.

This would be perfect if it worked. But one thing I’ve never played with in WordPress if the function.php file. And I tried to add that code to the function.php file but it doesn’t work. Should I put it somewhere specific in function.php or should it not matter ?

put it at the bottom but before ?> also try without the function title block of code, it doesn’t work, sorry i didn’t mean to post that section. Empty lines can sometimes break the functions.php as well.

Ok I’ll try that. But what do you mean by function title block of code ?

Sorry to ask. I’m not too familiar with function.php as I said before.

the third section of code that begins function title($num)

It works!

Very nice work around! And very useful

Thanks a lot

I tried it to and it work fine, but not in my “avatrs in recent comments” widget:-(

I also tried this: https://jarretcade.net/changing-the-default-wordpress-excerpt-length

I belive that is the best way to change the default exerpt.

Eivind

you could also try this:

`function my_excerpt_length($text){
return 10;

in the functions file

Thank you for the code you shared gerbilk ??

I have a small correction to make about the title one:
array_pop($excerpt);
should obviously be
array_pop($title);

just making sure for the newbies.

And on each of them:
$title = "<h2>".implode(" ",$title)."...</h2>";
or <p> …</p> for the excerpt etc.
makes it CSS-friendly ??

doh! thanks!

Yep ! Very usefull ! Thanks gerbilk, you’re the man ! ??

Hmm, since you are so generous with usefull code, is there a way to limit the excerpt, content or title by number of letters, not words ? ??
