Question

我在Wordpress中为自定义帖子开发了一个帮助器，我已经为随机自定义帖子（动物）创建了一个类，但是没有在对象中创建。现在我试图改进它以备将来使用。

我试图自定义更新消息，但它不起作用...... 在对象中，似乎有些事情会覆盖它，我不知道问题出在哪里

这是我的助手类：

<?php

class helper
{
    public $post_type_name;

    public function __construct( $name)
    {
        // Set some important variables
        $this->post_type_name        = strtolower( str_replace( ' ', '_', $name ) );


        // Add action to register the post type, if the post type does not already exist
        if( ! post_type_exists( $this->post_type_name ) )
        {
            add_action( 'init', array( &$this, 'register_post_type' ) );
            add_filter('post_updated_messages', 'helper_post_messages');
        }
    }
    public function register_post_type()
    {
        //Capitilize the words and make it plural
        $name       = ucwords( str_replace( '_', ' ', $this->post_type_name ) );
        $plural     = $name . 's';


        $labels = array(
            'name'                  => $plural, 'post type general name',
            'singular_name'         => $name, 'post type singular name',

添加过滤器参数必须是包含$this的数组，并且您的类的函数名称如下：

add_filter('post_updated_messages', array($this, 'helper_post_messages'));

几乎与你的

完全一样

add_action( 'init', array( &$this, 'register_post_type' ) );

并且您不需要&所以

add_action( 'init', array( $this, 'register_post_type' ) );

在自定义帖子上添加自定义消息
