你可以用多种方法来做。以下是最好的两种方法。

$post_id = 5// example post id
$post_content = get_post($post_id);
$content = $post_content->post_content;
echo do_shortcode( $content );//executing shortcodes

$content = get_post_field(\'post_content\', $post_id);
echo do_shortcode( $content );//executing shortcodes

您可以使用apply_filters 如果您想让其他插件过滤内容。因此，无需使用do_shortcode

实例

$post_id = 5// example post id
$post_content = get_post($post_id);
$content = $post_content->post_content;
echo apply_filters(\'the_content\',$content);
 //no need to use do_shortcode, but content might be filtered by other plugins.

如果你也不想使用短代码，那么只需使用post_content.

我只想在这里留下另一种令人讨厌的方式，你有时可能会觉得有用。当然，总是首选使用API调用的方法（get\\u post（）、get\\u the\\u content（）、…）。

global $wpdb;
$post_id = 123; // fill in your desired post ID
$post_content_raw = $wpdb->get_var(
    $wpdb->prepare(
        "select post_content from $wpdb->posts where ID = %d",
        $post_id
    )
);

$id = 23; // add the ID of the page where the zero is
$p = get_page($id);
$t = $p->post_title;
echo \'<h3>\'.apply_filters(\'post_title\', $t).\'</h3>\'; // the title is here wrapped with h3
echo apply_filters(\'the_content\', $p->post_content);

By using get_page(\'ID\').

$page_id = 123;  //Page ID
$page_data = get_page($page_id); 
$title = $page_data->post_title; 
$content = $page_data->post_content;
