从 Woocommerce 中的 URL 变量填写结帐字段值

Question

我有一个包含很多变量的 URL，使用 GET 例如 checkout/?FirstName=Test&LastName=Test&EmailAddress=Test

我想知道如何使用此信息预填充 WooCommerce 结账页面上的字段？即在 WooCommerce Checkout 中获取名字并填写名字？

任何帮助谢谢

Here below is an example with billing first name and last name based on Get url variables for checkout fields.

Its based on your Url example: checkout/?FirstName=Test&LastName=Test&EmailAddress=Test

The code:

add_filter( 'woocommerce_checkout_get_value' , 'custom_checkout_get_value', 20, 2 );
function custom_checkout_get_value( $value, $imput ) {
    // Billing first name
    if(isset($_GET['FirstName']) && ! empty($_GET['FirstName']) && $imput == 'billing_first_name' )
        $value = esc_attr( $_GET['FirstName'] );

    // Billing last name
    if(isset($_GET['LastName']) && ! empty($_GET['LastName']) && $imput == 'billing_last_name' )
        $value = esc_attr( $_GET['LastName'] );

    // Billing email
    if(isset($_GET['EmailAddress']) && ! empty($_GET['EmailAddress']) && $imput == 'billing_email' )
        $value = sanitize_email( $_GET['EmailAddress'] );

    return $value;
}

Code goes in function.php file of your active child theme (or active theme). Tested and works.
