Do_shortcode 函数在 WordPress 之外不起作用？

Question

当我尝试通过此代码运行短代码时：

define( 'WP_USE_THEMES', false );        
require_once('account/wp-blog-header.php');
require_once('account/wp-includes/shortcodes.php');

global $current_user;
get_currentuserinfo();
print_r($current_user);

get_header();
$page_object = get_page( 28 );
var_dump($page_object);
echo do_shortcode($page_object->post_content);

我得到的页面只有标题，所以 do_shortcode 不起作用。 page_object 的转储返回给我这个：

object(WP_Post)[276]
  public 'ID' => int 28
  public 'post_author' => string '1' (length=1)
  public 'post_date' => string '2015-09-22 12:14:16' (length=19)
  public 'post_date_gmt' => string '2015-09-22 12:14:16' (length=19)
  public 'post_content' => string '[pmpro_levels]' (length=14)
  public 'post_title' => string 'Membership Levels' (length=17)
  public 'post_excerpt' => string '' (length=0)
  public 'post_status' => string 'publish' (length=7)
  public 'comment_status' => string 'closed' (length=6)
  public 'ping_status' => string 'closed' (length=6)
  public 'post_password' => string '' (length=0)
  public 'post_name' => string 'levels' (length=6)
  public 'to_ping' => string '' (length=0)
  public 'pinged' => string '' (length=0)
  public 'post_modified' => string '2015-09-22 12:14:16' (length=19)
  public 'post_modified_gmt' => string '2015-09-22 12:14:16' (length=19)
  public 'post_content_filtered' => string '' (length=0)
  public 'post_parent' => int 22
  public 'guid' => string 'http://phpstack-10604-23437-55300.cloudwaysapps.com/account/membership-account-2/membership-levels/' (length=99)
  public 'menu_order' => int 0
  public 'post_type' => string 'page' (length=4)
  public 'post_mime_type' => string '' (length=0)
  public 'comment_count' => string '0' (length=1)
  public 'filter' => string 'raw' (length=3)

$page_object->post_content; 还给我 [pmpro_levels]，但是 do_shortcode() 不解析短代码。 一切都在 WordPress 目录中运行，你可以在我调用 wp-blog-header.php 的地方看到，但它不起作用。 为什么？

Answer 1

你应该试试 apply_filter

$content = apply_filters('the_content', $content);

apply_filters('the_content', $content);用于将内容过滤器应用于原始未过滤的帖子内容，这通常来自使用 $post->post_content。这些过滤器包括著名的过滤器 wp_autop，它将 p 标签添加到 the_content()

apply_filters('the_content', $content);通常与 get_posts 结合使用，其中直接使用 WP_Post 对象而不使用 setup_postdata( $post )，这使得模板标签如 the_content() 可供使用

更新 - 你的代码应该是这样的

get_header();
$page_object = get_page( 28 );
echo apply_filters('the_content', $page_object->post_content);
