修剪用户在content.php wordpress文件中输入摘录

Question

I have a custom function to trim the excerpt:

function custom_excerpt_length( $length ) {
return 10; }

and the filter to apply it:

add_filter( 'excerpt_length', 'custom_excerpt_length', 999 );

and then I get the excerpt in my content.php as:

<?php the_excerpt(); ?>

The function works if not custom user entered excerpt is found. so basically grabs the first 10 words from the blog post content. But it doesn't trim when I custom enter the excerpt. Any ideas to display the trimmed version of the user entered excerpt in the blog post page?

I finally got what I needed. So I just wanted to reduce the trimmed excerpt to a lower character count. I just added to my functions page:

function custom_excerpt_more( $more ) {
    $more = '…';
    return $more; 
}
add_filter( 'excerpt_more', 'custom_excerpt_more' ); //displays ... after the excerpt

function custom_excerpt_length( $length ) {
return 30; //number of words to display in the excerpt
}
add_filter( 'excerpt_length', 'custom_excerpt_length', 999 ); //999 si it filters at the end

And then in my content.php page:

<p><?php echo substr(get_the_excerpt(),0,80);?></p>

That way I get no more than 80 characters in my blog post list page and 30 words on my individual blog post page (content-single.php).
