本文介绍了使用会话中保存的 Url 变量预填充 Woocommerce 结账字段的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着跟版网的小编来一起学习吧!

问题描述

当人们通过销售电子邮件中的链接以电子邮件和姓名作为参数进入我的 woocommerce 商店时,我想在结帐页面中预先填写姓名和电子邮件.

When people enter the my woocommerce shop following a link in an sales email with email and name as parameters I would like to prefill the name and email in the checkout page.

因此我创建了一个动作和过滤器.这按预期工作,但前提是我在销售页面上进行了硬刷新 (ctrl + f5)

Therefore I created an action and filter. This works as expected but only if I do a hard refresh on the sales page (ctrl + f5)

我已经从缓存和清漆缓存中排除了销售页面和结账页面,但这并没有解决问题.

I've excluded the sales page and the checkout page from the cache and varnish cache but this didn't fix the issue.

我在这里遗漏了什么吗?你知道为什么这只适用于硬刷新吗?

Am I missing something here? Do you have any idea why this only works with a hard refresh?

非常感谢任何帮助.

代码:

    function save()
    {
    if ( is_page( 'sales-page' ) )
    {
        if ( isset( $_GET['tu_em'] ) ) {
            global $woocommerce;
            $woocommerce->session->set( 'tu_em', $_GET['tu_em'] );
        }
        if ( isset( $_GET['tu_name'] ) ) {
            global $woocommerce;
            $woocommerce->session->set( 'tu_name', $_GET['tu_name'] );
        }
    }
}
add_action( 'wp_enqueue_scripts', 'save_email' , 1100);

function override_checkout_email_field( $fields ) {
    global $woocommerce;
    $email = $woocommerce->session->get('tu_em');
    if(!is_null($email)) {
      $fields['billing']['billing_email']['default'] = $email;
    }
    $name = $woocommerce->session->get('tu_name');
    if(!is_null($name)) {
      $fields['billing']['billing_first_name']['default'] = $name;
    }
    return $fields;
}
add_filter( 'woocommerce_checkout_fields' , 'override_checkout_email_field' );

推荐答案

在下面,您将找到正确的工作代码,将来自 URL (GET) 的用户数据保存到 WooCommerce 会话中,并使用该数据自动填充相关结帐字段.

Here below, you will find the correct working code, to save user data from an URL (GET) into WooCommerce sessions and to autofill with that data the related checkout fields.

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

这可以从任何 URL 完成,因为代码会在设置 URL 变量时检测它们.

This can be done from any URL as the code will detect the URL variable, when they are set.

代码;

// 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;
}

代码位于您的活动子主题(或活动主题)的 function.php 文件中.经过测试并有效.
