Php 使用会话中保存的Url变量预填充电子商务签出字段

当人们进入my woocommerce商店时，会在销售电子邮件中添加一个链接，并将电子邮件和姓名作为参数，我希望在结帐页面中预先填充姓名和电子邮件

因此，我创建了一个操作和过滤器。这与预期一样有效，但仅当我在销售页面ctrl+f5上进行硬刷新时

我已经从缓存和清漆缓存中排除了销售页面和结帐页面，但这并没有解决问题

我是不是遗漏了什么？你知道为什么这只适用于硬刷新吗

非常感谢您的帮助

在下面，您将找到正确的工作代码，将URL中的用户数据保存到WooCommerce会话中，并使用该数据自动填充相关的签出字段

URL将类似于：http://example.com/sales-page/?tu_em=name@example.com&tu_name=firstname

这可以从任何URL完成，因为设置URL变量时，代码将检测URL变量

守则

// Save user data from URL to Woocommerce session
add_action( 'template_redirect', 'set_custom_data_wc_session' );
function set_custom_data_wc_session () {
    if ( isset( $_GET['tu_em'] ) || isset( $_GET['tu_name'] ) ) {
        $em   = isset( $_GET['tu_em'] )   ? esc_attr( $_GET['tu_em'] )   : '';
        $name = isset( $_GET['tu_name'] ) ? esc_attr( $_GET['tu_name'] ) : '';

        // Set the session data
        WC()->session->set( 'custom_data', array( 'email' => $em, 'name' => $name ) );
    }
}

// Autofill checkout fields from user data saved in Woocommerce session
add_filter( 'woocommerce_billing_fields' , 'prefill_billing_fields' );
function prefill_billing_fields ( $address_fields ) {
    // Get the session data
    $data = WC()->session->get('custom_data');

    // Email
    if( isset($data['email']) && ! empty($data['email']) )
        $address_fields['billing_email']['default'] = $data['email'];

    // Name
    if( isset($data['name']) && ! empty($data['name']) )
        $address_fields['billing_first_name']['default'] = $data['name'];

    return $address_fields;
}
