为WordPress文件添加重新关联附加选项方法

WordPress网站允许一个媒体文件关联附加到一篇文章，但是一般情况下是不能修改关联的，今天为大家分享一个为WordPress文件添加重新关联附加选项方法。

将下面代码添加到当前主题的 functions.php 文件:

add_filter(“manage_upload_columns”, ‘upload_columns’);

add_action(“manage_media_custom_column”, ‘media_custom_columns’, 0, 2);

function upload_columns($columns) {

unset($columns[‘parent’]);

$columns[‘better_parent’] = “Parent”;

return $columns;

}

function media_custom_columns($column_name, $id) {

$post = get_post($id);

if($column_name != ‘better_parent’)

return;

if ( $post->post_parent > 0 ) {

if ( get_post($post->post_parent) ) {

$title =_draft_or_post_title($post->post_parent);

}

?>

<strong><a href=”<?php%20echo%20get_edit_post_link(%20$post->post_parent%20);%20?>”><?php echo $title ?></a></strong>, <?php echo get_the_time(__(‘Y/m/d’)); ?>

<br />

<a class=”hide-if-no-js” onclick=”findPosts.open(‘media[]’,'<?php echo $post->ID ?>’);return false;” href=”#the-list”><?php _e(‘Re-Attach’); ?></a>

<?php

} else {

?>

<?php _e(‘(Unattached)’); ?><br />

<a class=”hide-if-no-js” onclick=”findPosts.open(‘media[]’,'<?php echo $post->ID ?>’);return false;” href=”#the-list”><?php _e(‘Attach’); ?></a>

<?php

}

}
