在Wordpress的摘录结尾处有3个点

Question

How to get ... (3 dots) at the end of the excerpt? I am using this function in my functions.php

function word_count($string, $limit) {
    $words = explode(' ', $string);
    return implode(' ', array_slice($words, 0, $limit));  
}

And echoing like this in my content.php:

echo word_count(get_the_excerpt(), '20');

I want 3 dots at the end of the excerpt. Please help. Thank you.

If your excerpts are always longer than 20 words, you can use the following to append ellipsis any time while truncate it with your word_count function

echo sprintf("%s…", word_count(get_the_excerpt(), 20));

If the excerpts might also be 20 words or shorter, you should also check for it's length

the_excerpt_max_words(20);

function the_excerpt_max_charlength($limit) {

    $words = explode(' ', get_the_excerpt() );

    //if excerpt has more than 20 words, truncate it and append ... 
    if( count($words) > 20 ){
        return sprintf("%s…", implode(' ', array_slice($words, 0, $limit)) );
    }

    //otherwise just put it back together and return it
    return implode(' ', $words);

}
