PHP 通过单词限制WordPress the_content

Posted 2021-05-14

//Example: apply_filters( 'the_content', wp_trim_words( get_the_content(), 15, '…' ) )

//Add this function to your functions.php file
function get_news($cat_slug, $limit){


 $my_query = new WP_Query('category_name='.$cat_slug.'&posts_per_page='.$limit);

	$result = "<ul class='news-feed'>";

  	while ($my_query->have_posts()) : $my_query->the_post(); 
		$result .= '<li class="news-item"><a href="' . get_permalink() . '" target="_blank">' . get_the_title() . '</a><p>';
		$result .= apply_filters( 'the_content', wp_trim_words( get_the_content(), 15, '…' ) ) . ' <a href="' . get_permalink() . '" target="_blank" class="read_more"><strong>read more</strong> »</a>';
		$result .= '</li>';
	endwhile; 
  		$result .= '</ul>';
  	return $result;
}

//Usage:
// get company news from the 'news' category with limit of 2 posts
print get_news('news', 2);
