好的,这可能是重复的,我只是无法将我的想法输入适当的搜索字词,对此表示歉意！

是否有内置函数或模板标签来获取内容的前n个单词?我的意思是the_content().

谢谢！

OK, this might be a duplicate, I was just unable to put my idea in proper search terms, sorry for that!

Is there a built-in function or template tag to get the first n words of the content? I mean the_content().

Thanks!

functions content template-tags

是的, wp_trim_words() :

<?php $trimmed = wp_trim_words( $text, $num_words = 55, $more = null ); ?>

或者您的情况:

<?php echo apply_filters( 'the_content', wp_trim_words( strip_tags( $post->post_content ), 55 ) ); ?>
Yep, wp_trim_words():

<?php $trimmed = wp_trim_words( $text, $num_words = 55, $more = null ); ?>

Or in your case:

<?php echo apply_filters( 'the_content', wp_trim_words( strip_tags( $post->post_content ), 55 ) ); ?>
- @JaromírtheGreenhorn如果您想在`get_the_content()`上使用它,则需要事先剥离HTML(请参阅修订).
  
  @JaromírtheGreenhorn If you'd like to use this on `get_the_content()`, you'll need to strip HTML beforehand (see revision).

- 这似乎对我有用,无需额外剥离,但很高兴知道.
  
  It seems to work for me without extra strip down, but good to know.

- 我仍然强烈建议您使用它-它可能现在可以使用,但是最终您将得到格式错误的HTML.
  
  I would still strongly advise that you use it - it might be working now, but eventually you'll end up with malformed HTML.
