Ich verwende diesen Code, um benutzerdefinierte Checkout-Felder zu erstellen und Felder neu anzuordnen:

add_filter( 'woocommerce_checkout_fields', 'custom_checkout_billing_fields' );
function custom_checkout_billing_fields( $fields ) {

// 1. Creating the additional custom billing fields

    // The "status" selector
    $fields['billing']['billing_status']['type'] = 'select';
    $fields['billing']['billing_status']['class'] = array('form-row-wide, status-select');
    $fields['billing']['billing_status']['required'] = true;
    $fields['billing']['billing_status']['label'] = __('User status', 'my_theme_slug');
    $fields['billing']['billing_status']['placeholder'] = __('Chose an option', 'my_theme_slug');
    $fields['billing']['billing_status']['options'] = array(
        '' => 'Chose an option',
        '1' => 'Legal entity',
        '2' => 'Individual'
    );

    // The "Serial ID" text field
    $fields['billing']['billing_number_id']['type'] = 'text';
    $fields['billing']['billing_number_id']['class'] = array('form-row-wide', 'status-group1');
    $fields['billing']['billing_number_id']['required'] = true;
    $fields['billing']['billing_number_id']['label'] = __('Serial ID', 'my_theme_slug');
    $fields['billing']['billing_number_id']['placeholder'] = __('Enter your Serial ID', 'my_theme_slug');

    // Customizing 'billing_company' field ['required']
    $fields['billing']['billing_company']['required'] = false;

    // The "Serial ID" text field
    $fields['billing']['billing_serial']['type'] = 'text';
    $fields['billing']['billing_serial']['class'] = array('form-row-wide', 'status-group1');
    $fields['billing']['billing_serial']['required'] = false;
    $fields['billing']['billing_serial']['label'] = __('Serial ID', 'my_theme_slug');
    $fields['billing']['billing_serial']['placeholder'] = __('Enter your Serial ID', 'my_theme_slug');


// 2. Customizing 'billing_email' and 'billing_phone' fields ['class']

    $fields['billing']['billing_email']['class'] = array('form-row-first', 'status-group1');
    $fields['billing']['billing_phone']['class'] = array('form-row-last', 'status-group1');


// 3. Ordering the billing fields

    $fields_order = array(
        'billing_first_name', 'billing_last_name', 'billing_email',
        'billing_phone',      'billing_address_1', 'billing_address_2',
        'billing_postcode',   'billing_city',      'billing_country',
        'billing_status',
        'billing_company',   'billing_number_id',  'billing_serial'
    );
    foreach($fields_order as $field) $ordered_fields[$field] = $fields['billing'][$field];

    $fields['billing'] = $ordered_fields;


// Returning Checkout customized billing fields

    return $fields;

}

Der bedingte Mechanismus:

tandardmäßig ist dasbilling_status Dropdown-Auswahl wird auf @ seIndividual Optionswert und zeigtnurbilling_serial benutzerdefinierte FeldWenn diebilling_status Dropdown-Auswahl wird auf @ umgeschalt"Company" ** Optionswert, 2 weitere Felder werden angezeigt:billing_company existierendes Feld (vorbilling_serial)billing_number_id benutzerdefinierte Felder (am Ende)

Wie kann ich das erreichen?

Vielen Dan
