[Resolved] Changing length of the_excerpt without changing it on the whole wordpress

  • Hi,

    I’m using the popular Category Post Widget to show the latest posts from a category on a sidebar of my website.

    The plugin uses the_excerpt to pull the excerpt and show it in the sidebar widget plugin.

    Basically, I’d like to change the length of the_excerpt that is shown, just in that plugin in the sidebar.


    On the above topic, some solutions to do this were presented but that would require to edit function.php and I don’t want to do that because I don’t want to affect all the instances of the_excerpt on my website, but just in the plugin.

    The ideal would be if there were a parameter to directly tell the_excerpt how many words to pull. Unfortunately, such a parameter don’t exist, I think.

    So, is there a solution ?

    Maybe something else than the_excerpt to pull the excerpt with the possibility of choosing the number a words via some parameter. Or maybe a parameter for the_excerpt I don’t know of ?

    Or another plugin that lets me do that? All of this seems pretty basic but after days I don’t seem to have found a solution everywhere I looked. Any help would be highly appreciated. Thanks

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


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


    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: http://jarretcade.net/changing-the-default-wordpress-excerpt-length

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


    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:
    should obviously be

    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 ? 🙂

    wow – a gr8 solution 🙂
    10x man.. gona use it for multiple themes!
