我正在尝试删除操作并使用不同的优先级添加它。 以下是有助于生成消息的所有代码片段:
包含所需的前端文件
private function frontend_includes() {
require_once( $this->get_plugin_path() . '/includes/wc-memberships-template-functions.php' );
require_once( $this->get_plugin_path() . '/includes/class-wc-memberships-shortcodes.php' );
WC_Memberships_Shortcodes::initialize();
$this->frontend = $this->load_class( '/includes/frontend/class-wc-memberships-frontend.php', 'WC_Memberships_Frontend' );
$this->checkout = $this->load_class( '/includes/frontend/class-wc-memberships-checkout.php', 'WC_Memberships_Checkout' );
$this->restrictions = $this->load_class( '/includes/frontend/class-wc-memberships-restrictions.php', 'WC_Memberships_Restrictions' );
}
获取产品购买限制消息
/**
* @param int $post_id Optional. Defaults to current post.
* @return string
*/
public function get_product_purchasing_restricted_message( $post_id = null ) {
if ( ! $post_id ) {
global $post;
$post_id = $post->ID;
}
$products = $this->get_products_that_grant_access( $post_id );
$message = $this->get_restriction_message( 'product_purchasing_restricted', $post_id, $products );
/**
* Filter the product purchasing restricted message
*
* @since 1.0.0
* @param string $message The restriction message
* @param int $product_id ID of the product being restricted
* @param array $products Array of product IDs that grant access to this product
*/
return apply_filters( 'wc_memberships_product_purchasing_restricted_message', $message, $post_id, $products );
}
限制类,处理前端的内容限制
class WC_Memberships_Restrictions {
/** @var array associative array of content conditions for current user **/
private $user_content_access_conditions;
/** @var array of post IDs that content restriction has been applied to **/
private $content_restriction_applied = array();
/** @var string Product content restriction password helper **/
private $product_restriction_password = null;
/** @var bool Product thumbnail removed helper **/
private $product_thumbnail_restricted = false;
public function __construct() {
// Desired action to remove and re-prioritize
add_action( 'woocommerce_single_product_summary', array( $this, 'single_product_purchasing_restricted_message' ), 30 );
}
}
我确实需要在WC_Memberships_Restrictions类的操作中将优先级从30改为15。问题在于没有明确的方法来调用删除。有什么建议吗?
答案 0 :(得分:3)
您提供的代码表明WC_Memberships_Restrictions
类的实例存储在主类“restrictions
属性中。
$this->restrictions = $this->load_class( '/includes/frontend/class-wc-memberships-restrictions.php', 'WC_Memberships_Restrictions' );
从那里我只需要查看如何从您看到的主插件文件的底部访问主要Membership类的实例:
/**
* Returns the One True Instance of Memberships
*
* @since 1.0.0
* @return WC_Memberships
*/
function wc_memberships() {
return WC_Memberships::instance();
}
这意味着现在要访问限制类的实例,我们需要访问主类的restriction属性。虽然这听起来像泥,但基本上它意味着:
wc_memberships()->restrictions
了解这一点,我们可以知道从该类删除并添加操作:
function so_41431558_change_hook_priority(){
if( function_exists( 'wc_memberships' ) ){
remove_action( 'woocommerce_single_product_summary', array( wc_memberships()->restrictions, 'single_product_purchasing_restricted_message' ), 30 );
add_action( 'woocommerce_single_product_summary', array( wc_memberships()->restrictions, 'single_product_purchasing_restricted_message' ), 15 );
}
}
add_action( 'woocommerce_single_product_summary', 'so_41431558_change_hook_priority', 1 );
