http://codex.wordpress.org/Function_Reference/register_post_type 示例:
//add filter to ensure the text Book, or book, is displayed when user updates a book
add_filter('post_updated_messages', 'codex_book_updated_messages');
function codex_book_updated_messages( $messages ) {
global $post, $post_ID;
$messages['book'] = array(
0 => '', // Unused. Messages start at index 1.
1 => sprintf( __('Book updated. <a href="%s">View book</a>'), esc_url( get_permalink($post_ID) ) ),
2 => __('Custom field updated.'),
3 => __('Custom field deleted.'),
4 => __('Book updated.'),
/* translators: %s: date and time of the revision */
5 => isset($_GET['revision']) ? sprintf( __('Book restored to revision from %s'), wp_post_revision_title( (int) $_GET['revision'], false ) ) : false,
6 => sprintf( __('Book published. <a href="%s">View book</a>'), esc_url( get_permalink($post_ID) ) ),
7 => __('Book saved.'),
8 => sprintf( __('Book submitted. <a target="_blank" href="%s">Preview book</a>'), esc_url( add_query_arg( 'preview', 'true', get_permalink($post_ID) ) ) ),
9 => sprintf( __('Book scheduled for: <strong>%1$s</strong>. <a target="_blank" href="%2$s">Preview book</a>'),
// translators: Publish box date format, see http://php.net/date
date_i18n( __( 'M j, Y @ G:i' ), strtotime( $post->post_date ) ), esc_url( get_permalink($post_ID) ) ),
10 => sprintf( __('Book draft updated. <a target="_blank" href="%s">Preview book</a>'), esc_url( add_query_arg( 'preview', 'true', get_permalink($post_ID) ) ) ),
);
return $messages;
}
数组的'message'
一部分$_GET
负责将实际消息值保存为integer
。这意味着传入的所有内容都将设置为实际消息。邮件本身存储在Admin UI模板的全局数组中。它已命名$messages
,默认情况下具有三个键:
page
post
attachment
消息存储为主$messages
数组的子数组。
注意事项(WP核心v4.0.1):
0
使用中是没有的。attachment
消息目前是一个黑客,只是有串'Media attachment updated.'
上的每一个关键。使用post_updated_messages
过滤器:
add_filter( 'post_updated_messages', function( $messages )
{
$messages['post'][2] = 'My awesome custom field just updated. Congratulations!';
return $messages;
} );
查看~/wp-admin/edit-form-advanced.php
哪个消息用于什么。
如果未使用任何帖子类型,则后备是
post
帖子类型消息数组。
您可以通过预定过滤器上的回调安全地添加自己的消息集。只要确保您使用自定义帖子类型名称作为message数组的键即可:
add_filter( 'post_updated_messages', function( $messages )
{
$messages['my_custom_post_type'][2] = 'Go, buy some milk!';
return $messages;
} );
回调本身可能是最好的挂钩
do_action( "load-{$pagenow}" )
认为这可能会有所帮助。
经过各种站点的长度和广度之后,我只能在此帮助下获得显示的自定义消息。
