PHP Question…

Is it possible to just add a filter to lower the default excerpt length similar to something like this?

Control Excerpt Length using Filters

Or would that cause conflict in this case with excerpts used elsewhere on your site? Just for my own curiosity, does “strip_tags” have any effect on the_excerpt in this case? – or would html be automatically stripped anyhow? Just ball-parking, mind you. I guess I really don’t know for sure.

Maybe something like:

$length = 30; //Or whatever number of words you want
$excerpt = strip_tags(get_the_excerpt());
$words = explode(' ', $excerpt);
if(count($words) > $length ){
    array_splice($words, $count);
    $excerpt = implode(' ', $words);
}
echo $excerpt;

Thanks guys… I don’t understand where all that php would go… this is in the tag.php template. Can you lay it out within the example I have above?

Thanks!

Yup, just replace <?php strip_tags( the_excerpt() ); ?> with:

$length = 30; //Or whatever number of words you want
$excerpt = strip_tags(get_the_excerpt());
$words = explode(' ', $excerpt);
if(count($words) > $length ){
    array_splice($words, $count);
    $excerpt = implode(' ', $words);
}
echo $excerpt;

In your tag.php template.

or simply add to functions.php

function new_excerpt_length($length) {
	return 20;
}
add_filter('excerpt_length', 'new_excerpt_length')

okay, super.. thanks… one more clarification. for functions.php, sure I can add that, but do i just slap in there exactly as you have it written? And then the code I have on tag.php doesn’t need to be changed?

Thanks!

The code I posted will change the excerpt length wherever get_the_excerpt() is called
