[英]Wordpress - Using functions outside of wordpress
I'm using the following code to access my wordpress from another page: 我正在使用以下代码从另一个页面访问我的wordpress:
<?php
include $_SERVER['DOCUMENT_ROOT'].'/wp-load.php';
global $wpdb;
$image_ID = $wpdb->get_var("SELECT post_id FROM $wpdb->postmeta WHERE meta_value = '6036' AND meta_key = '_wp_attached_file'");
//regenerate thumbnail
$fullsizepath = get_attached_file( $image_ID );
$metadata = wp_generate_attachment_metadata( $image_ID, $fullsizepath );
wp_update_attachment_metadata( $image_ID, $metadata );
?>
I get the following error: 我收到以下错误:
Fatal error: Call to undefined function wp_generate_attachment_metadata()
The $wpdb query works fine and get_attached_file, too. $ wpdb查询和get_attached_file也可以正常工作。 The only problem is that I can't use wp_generate_attachment_metadata .
唯一的问题是我不能使用wp_generate_attachment_metadata 。
Does anybody know why that happens? 有人知道为什么会这样吗? Did I forget to include something?
我忘了包括一些东西吗?
EDIT: I just realized I just forgot to include( ABSPATH . 'wp-admin/includes/image.php' );
编辑:我刚刚意识到我只是忘了
include( ABSPATH . 'wp-admin/includes/image.php' );
You need to include wp-blog-header.php to set up the wordpress environment. 您需要包括wp-blog-header.php来设置wordpress环境。
<?php
require('blog/wp-blog-header.php');
$args = array( 'numberposts' => 5, 'post_status'=>"publish", 'post_type'=>"post", 'orderby'=>"post_date");
$postslist = get_posts( $args );
foreach ($postslist as $post) : setup_postdata($post); ?>
<ul class="headline">
<li class="title">
<a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a></li>
</ul>
<?php endforeach; ?>
