限制 WooCommerce 上的域名注册

如何限制用户电子邮件对 WooCommerce 注册中特定域的访问？

我发现这段代码可以做到这一点，但由于某种原因它在 WooCommerce 注册表单上不起作用。

如果我进入 WP 登录页面，它就会起作用。

任何帮助表示赞赏。

function is_valid_email_domain($login, $email, $errors ){

    $valid_email_domains = array("gmail.com", "yahoo.com");// allowed domains
    $valid = false; // sets default validation to false
    foreach( $valid_email_domains as $d ){
        $d_length = strlen( $d );
        $current_email_domain = strtolower( substr( $email, -($d_length), $d_length));
        if( $current_email_domain == strtolower($d) ){
            $valid = true;
            break;
        }
    }
 // Return error message for invalid domains
    if( $valid === false ){
        $errors->add('domain_whitelist_error',__( '<strong>ERROR</strong>: Registration is only allowed from selected approved domains. If you think you are seeing this in error, please contact the system administrator.' ));
    }
}

add_action('register_post', 'is_valid_email_domain',10,3 ); //this works
// add_action('woocommerce_register_form', 'is_valid_email_domain',10,0); //getting errors
// add_action('user_register', 'is_valid_email_domain',10,3 ); //getting errors

在 WooCommerce 中使用的正确挂钩是woocommerce_register_post动作挂钩。试试这个：

add_action('woocommerce_register_post','is_valid_registration_email_domain', 10, 3 );
function is_valid_registration_email_domain( $username, $email, $validation_errors ){
    $valid_email_domains = array( 'gmail.com', 'yahoo.com' ); // Allowed domains
    $valid = false; // sets default validation to false
    foreach( $valid_email_domains as $d ){
        $d_length = strlen( $d );
        $current_email_domain = strtolower( substr( $email, -($d_length), $d_length));
        if( $current_email_domain == strtolower($d) ){
            $valid = true;
            break;
        }
    }

    // Return error message for invalid domains
    if( ! $valid ){
        $error_text = __( "<strong>ERROR</strong>: Registration is only allowed from selected approved domains. If you think you are seeing this in error, please contact the system administrator.", "woocommerce" );
        $validation_errors->add( 'domain_whitelist_error', $error_text );
    }
}

代码位于活动子主题（或主题）的 function.php 文件中。

经过测试并有效。
