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

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

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 );

(将75更改为你想要的任何长度)
