multiple excerpt length in wordpress - wordpress

Question

I'm using the following function for an excerpt in Wordpress.
<?php
// Excerpt - end of sentence
function custom_wp_trim_excerpt($text) {
$raw_excerpt = $text;
if ('' == $text) {
// Retrieve the post content.
$text = get_the_content('');
// Delete all shortcode tags from the content.
$text = strip_shortcodes($text);
$text = apply_filters('the_content', $text);
$text = str_replace(']]>', ']]>', $text);
$allowed_tags = '<i>,<strong>';
$text = strip_tags($text, $allowed_tags);
$excerpt_word_count = 40;
$excerpt_length = apply_filters('excerpt_length', $excerpt_word_count);
$excerpt_end = '...' . '<div class="read-more"><a class="button" href="' . get_permalink($post->ID) . '">' . 'Read More' . '</a></div>';
$excerpt_more = apply_filters('excerpt_more', ' ' . $excerpt_end);
$words = preg_split("/[\n\r\t ]+/", $text, $excerpt_length + 1, PREG_SPLIT_NO_EMPTY);
if (count($words) > $excerpt_length) {
array_pop($words);
$text = implode(' ', $words);
$text = $text . $excerpt_more;
}
else {
$text = implode(' ', $words);
}
}
return apply_filters('wp_trim_excerpt', $text, $raw_excerpt);
}
remove_filter('get_the_excerpt', 'wp_trim_excerpt');
add_filter('get_the_excerpt', 'custom_wp_trim_excerpt');
I want to add a second word count to use on the blog page. The above word count is being used on the front page. Advice, please? Thanks.

Answer 1

Try this piece of code
function custom_wp_trim_excerpt($text) {
if ( is_front_page() || is_home() ) {
// Excerpt for front page or home page
} else {
// Excerpt for rest of the site
}
}
remove_filter('get_the_excerpt', 'wp_trim_excerpt');
add_filter('get_the_excerpt', 'custom_wp_trim_excerpt');
By using this piece of code you have more control over the excerpt that is outputted on different pages.
If that worked mark your question as solved.
