我如何获取帖子的几个词

如何获得没有摘录的帖子的前几个词？

$args = array( 'posts_per_page'=> 5, 'offset'=> 0, 'category'=> '', 'category_name'=> 'Energy', 'orderby'=> 'date', 'order'=> 'DESC', 'include'=> '', 'exclude'=> '', 'meta_key'=> '', 'meta_value'=> '', 'post_type'=> 'post', 'post_mime_type'=> '', 'post_parent'=> '', 'author'=> '', 'author_name'=> '', 'post_status'=> 'publish', 'suppress_filters' => true ); $posts_array = get_posts( $args ); foreach($posts_array as $postCategory) { echo get_the_title( $postCategory-> ID ); echo get_permalink( $postCategory-> ID ); echo get_the_excerpt( $postCategory-> ID ); // THIS WITH OU WITHOUT EXCERPT DOES NOT WORK }

该代码正在打印标题和固定链接, 但不打印帖子的前几个单词。
我想了解如何打印帖子的前几个单词, 无论它是否具有摘录分隔符。
谢谢
#1

$trimtitle = get_the_content($post-> ID); $shorttitle = wp_trim_words( $trimtitle, $num_words = 15, $more = '… ' ); ?> < ?php echo $shorttitle; ?>

#2为此, 你需要添加以下功能：

function truncate_string ($string, $maxlength) {// Set the replacement for the "string break" in the wordwrap function $cutmarker = "**cut_here**"; // Checking if the given string is longer than $maxlength if (strlen($string) > $maxlength) {// Using wordwrap() to set the cutmarker // NOTE: wordwrap (PHP 4 > = 4.0.2, PHP 5) $string = wordwrap($string, $maxlength, $cutmarker); // Exploding the string at the cutmarker, set by wordwrap() $string = explode($cutmarker, $string); }// returning $string return $string; }

然后在你的foreach循环中添加以下内容：

$content_post = get_post( $postCategory-> ID ); $content = $content_post-> post_content; $content = apply_filters('the_content', $content); $content = str_replace(']]> ', ']]& gt; ', $content); echo truncate_string( $content, 75 );
