将多个 WooCommerce 自定义结帐字段保存为订单元数据

Question

Im looking to find some php code that will allow me to extract information (Name, address etc) from the checkout fields and add it to the order meta data.

Looking for this to be a simple as possible

Ive previously found this code which allows a custom box to be added to the checkout page, and I sort of understand how it works, however I want to capture their name when they type it into the billing first name box. I can seem to grasp how to capture this data and put it into the order meta data, Ive tried shortening the code and editing it a few times but I dont seem to be winning

// Our hooked in function - $fields is passed via the filter!
function custom_override_checkout_fields( $fields ) {
     $fields['shipping']['shipping_phone'] = array(
        'label'     => __('Phone', 'woocommerce'),
    'placeholder'   => _x('Phone', 'placeholder', 'woocommerce'),
    'required'  => false,
    'class'     => array('form-row-wide'),
    'clear'     => true
     );

     return $fields;
}

/**
 * Display field value on the order edit page
 */
 
add_action( 'woocommerce_admin_order_data_after_shipping_address', 'my_custom_checkout_field_display_admin_order_meta', 10, 1 );

function my_custom_checkout_field_display_admin_order_meta($order){
    echo '<p><strong>'.__('Phone From Checkout Form').':</strong> ' . get_post_meta( $order->get_id(), '_shipping_phone', true ) . '</p>';
}
/**
 * Add the field to the checkout
 */
add_action( 'woocommerce_after_order_notes', 'my_custom_checkout_field' );

function my_custom_checkout_field( $checkout ) {

    echo '<div id="my_custom_checkout_field"><h2>' . __('My Field') . '</h2>';

    woocommerce_form_field( 'my_field_name', array(
        'type'          => 'text',
        'class'         => array('my-field-class form-row-wide'),
        'label'         => __('Fill in this field'),
        'placeholder'   => __('Enter something'),
        ), $checkout->get_value( 'my_field_name' ));

    echo '</div>';

}
/**
 * Process the checkout
 */
add_action('woocommerce_checkout_process', 'my_custom_checkout_field_process');

function my_custom_checkout_field_process() {
    // Check if set, if its not set add an error.
    if ( ! $_POST['my_field_name'] )
        wc_add_notice( __( 'Please enter something into this new shiny field.' ), 'error' );
}
/**
 * Update the order meta with field value
 */
add_action( 'woocommerce_checkout_update_order_meta', 'my_custom_checkout_field_update_order_meta' );

function my_custom_checkout_field_update_order_meta( $order_id ) {
    if ( ! empty( $_POST['my_field_name'] ) ) {
        update_post_meta( $order_id, 'My Field', sanitize_text_field( $_POST['my_field_name'] ) );
    }
}

I like this and it does work but just not in the way i need it to work. thanks for any and all help

There are some mistakes and missing things in your code… Try the following replacement code instead:

// Add shipping phone (in checkout and My account edit shipping address) and save field value
add_action( 'woocommerce_shipping_fields', 'add_shipping_phone_field' );
function add_shipping_phone_field( $fields ) {
     $fields['shipping_phone'] = array(
        'label'     => __('Phone', 'woocommerce'),
        'placeholder'   => _x('Phone', 'placeholder', 'woocommerce'),
        'required'  => false,
        'class'     => array('form-row-wide'),
        'clear'     => true
     );

     return $fields;
}

// Display shipping phone value on the order edit pages under shipping section
add_action( 'woocommerce_admin_order_data_after_shipping_address', 'display_shipping_phone_in_admin_orders' );
function display_shipping_phone_in_admin_orders( $order ){
    $phone_value = $order->get_meta('_shipping_phone');

    if ( ! empty($phone_value) ) {
        echo '<p><strong>'.__('Shipping phone').':</strong> ' . $phone_value . '</p>';
    }
}

// Add a custom checkout field
add_action( 'woocommerce_after_order_notes', 'my_custom_checkout_field' );
function my_custom_checkout_field( $checkout ) {

    echo '<div id="my_custom_checkout_field"><h2>' . __('My Field') . '</h2>';

    woocommerce_form_field( 'my_field_slug', array(
        'type'          => 'text',
        'class'         => array('my-field-class form-row-wide'),
        'label'         => __('My custom field'),
        'placeholder'   => __('Enter something… '),
        'required'      => true,
    ), $checkout->get_value( 'my_field_slug' ) );

    echo '</div>';
}
// Validate required checkout fields
add_action('woocommerce_checkout_process', 'my_custom_checkout_field_process');
function my_custom_checkout_field_process() {
    // Check if set, if its not set add an error.
    if ( isset($_POST['my_field_slug']) && empty($_POST['my_field_slug']) ) {
        wc_add_notice( __( '"My custom field" is a required field.' ), 'error' );
    }
}

// Add custom checkout field value as custom order meta data
add_action( 'woocommerce_checkout_create_order', 'my_custom_checkout_field_update_order_meta' );
function my_custom_checkout_field_update_order_meta( $order ) {
    if ( isset($_POST['my_field_slug']) && ! empty($_POST['my_field_slug']) ) {
        $order->update_meta_data( 'My Field', sanitize_text_field( $_POST['my_field_slug'] ) );
    }
}

// Display "My field" value on the order edit pages under billing section
add_action( 'woocommerce_admin_order_data_after_billing_address', 'display_my_custom_checkout_field_in_admin_orders', 10, 1 );
function display_my_custom_checkout_field_in_admin_orders($order){
    $my_field_value = $order->get_meta('My Field');

    if ( ! empty($my_field_value) ) {
        echo '<p><strong>'.__('My field').':</strong> ' . $my_field_value . '</p>';
    }
}

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

Now If you need to extract some data from Woocommerce existing checkout fields and combine it in a custom way to save it as custom order meta data, try to be more explicit:

• What fields?
• How you want to combine it?
• What is the custom field slug to be used to save that data combination?
