是的,您可以这样做,但您需要调整<?php the_excerpt(); ?> 作用这是一篇关于如何做到这一点的好文章:

为了总结这篇文章,以防它消失,把它放在你的主题功能中。php文件:
function improved_trim_excerpt($text) {
        global $post;
        if ( \'\' == $text ) {
                $text = get_the_content(\'\');
                $text = apply_filters(\'the_content\', $text);
                $text = str_replace(\'\\]\\]\\>\', \']]>\', $text);
                $text = preg_replace(\'@<script[^>]*?>.*?</script>@si\', \'\', $text);
                $text = strip_tags($text, \'<img>\');
                $excerpt_length = 80;
                $words = explode(\' \', $text, $excerpt_length + 1);
                if (count($words)> $excerpt_length) {
                        array_pop($words);
                        array_push($words, \'[...]\');
                        $text = implode(\' \', $words);
                }
        }
        return $text;
}
remove_filter(\'get_the_excerpt\', \'wp_trim_excerpt\');
add_filter(\'get_the_excerpt\', \'improved_trim_excerpt\');
 注意这一行,这是告诉函数除去除
<img> 标签。如果希望包含段落标记或其他内容,可以添加其他内容:
$text = strip_tags($text, \'<img>\');
 然后调用\\u摘录();像往常一样,在主题文件中(index.php、single.php等)。
祝你好运!
