我以前使用过这里描述的解决方案：remove_action From PHP Class用于删除 WooCommerce 会员插件中的操作。

但是，该解决方案不再有效，因为 WooComerce 更改了会员插件背后的代码。

所以这是新代码。

主 woocommerce-memberships.php

public function includes() {

    // load post types
    require_once( $this->get_plugin_path() . '/includes/class-wc-memberships-post-types.php' );

    // load user messages helper
    require_once( $this->get_plugin_path() . '/includes/class-wc-memberships-user-messages.php' );

    // load helper functions
    require_once( $this->get_plugin_path() . '/includes/functions/wc-memberships-functions.php' );

    // init general classes
    $this->rules            = $this->load_class( '/includes/class-wc-memberships-rules.php',            'WC_Memberships_Rules' );
    $this->plans            = $this->load_class( '/includes/class-wc-memberships-membership-plans.php', 'WC_Memberships_Membership_Plans' );
    $this->emails           = $this->load_class( '/includes/class-wc-memberships-emails.php',           'WC_Memberships_Emails' );
    $this->user_memberships = $this->load_class( '/includes/class-wc-memberships-user-memberships.php', 'WC_Memberships_User_Memberships' );
    $this->capabilities     = $this->load_class( '/includes/class-wc-memberships-capabilities.php',     'WC_Memberships_Capabilities' );
    $this->member_discounts = $this->load_class( '/includes/class-wc-memberships-member-discounts.php', 'WC_Memberships_Member_Discounts' );
    $this->restrictions     = $this->load_class( '/includes/class-wc-memberships-restrictions.php',     'WC_Memberships_Restrictions' );

主要实例

    function wc_memberships() {
    return WC_Memberships::instance();
}

来自包含的 class-wc-memberships-restrictions.php 文件

    /**
 * Returns the general content restrictions handler.
 *
 * @since 1.9.0
 *
 * @return null|\WC_Memberships_Posts_Restrictions
 */
public function get_posts_restrictions_instance() {

    if ( ! $this->posts_restrictions instanceof WC_Memberships_Posts_Restrictions ) {
        $this->posts_restrictions = wc_memberships()->load_class( '/includes/frontend/class-wc-memberships-posts-restrictions.php', 'WC_Memberships_Posts_Restrictions' );
    }

    return $this->posts_restrictions;
}

然后在 class-wc-memberships-posts-restrictions.php

    public function __construct() {

    // decide whether attempting to access restricted content has to be redirected
    add_action( 'wp', array( $this, 'handle_restriction_modes' ) );

    // restrict the post by filtering the post object and replacing the content with a message and maybe excerpt
    add_action( 'the_post', array( $this, 'restrict_post' ), 0 );

如何删除“the_post”操作？

到目前为止，我在 functions.php 主题文件中有以下内容：

  function weteach_remove_actions(){
      if(is_singular( 'post' )) {
         if( function_exists( 'wc_memberships' ) ){
             remove_action( 'the_post', array( wc_memberships()->restrictions, 'restrict_post' ));
         }
      }
      return;
  }
  add_action( 'the_post', 'weteach_remove_actions', 1 );

这给了我一个“空白页”错误。

你能告诉我们错误信息是什么吗？我的猜测是，restrictions并且post_restrictions不是同一个属性，因此您没有restrict_post在正确的类中找到该方法。

现在我已经查看了会员资格，这似乎对我有用：

function so_41431558_remove_membership_post_restrictions(){ 
    if( function_exists( 'wc_memberships' ) && version_compare( WC_Memberships::VERSION, '1.9.0', '>=' ) && is_singular( 'post' ) ){
        remove_action( 'the_post', array( wc_memberships()->get_restrictions_instance()->get_posts_restrictions_instance(), 'restrict_post' ), 0 );
    }
}
add_action( 'wp_head', 'so_41431558_remove_membership_post_restrictions', 1 );

您的add_action尝试发生在优先级 1 上，这是在函数已经在优先级 0 上运行 Memberships 方法之后，所以即使您的其余代码是正确的，也为时已晚。

所以 1. 我认为我们需要去更早的钩子。

2.我认为我们需要使用新方法来访问帖子限制类实例。

编辑添加

和 3. 我已经切换到直接版本比较条件

和 4. 我误读了get_posts_restrictions_instance()方法的位置......它通过以下方式访问wc_memberships()->get_restrictions_instance()->get_posts_restrictions_instance()
