WordPress tip : change excerpt length depending of the category

WordPress tip : change excerpt length depending of the category

Do you ever wished to be able to modify the excerpt length based on which category you are on, without modifying your theme files? If yes, I’m pretty sure you’ll be happy with that recipe.

No need to modify your theme files. Simply paste the code into your functions.php file. Don't forget to change the category ID on line 3!

add_filter('excerpt_length', 'my_excerpt_length');
function my_excerpt_length($length) {
    if(in_category(14)) {
        return 13;
    } else {
        return 60;
    }
}

It worked perfectly in my theme, but in the matter of use it in a specific part of my template, instead of write the code in the function.php file I put it into the header.php above the DOCTYPE tag and using the conditional
if (is_home()) {
function my_excerpt_length($length) {
if (in_category(1)) {
return 9;
}
}
add_filter(‘excerpt_length’, ‘my_excerpt_length’);
}
