Add custom field to checkout form

Hi,
i just wanna ask if you found a solution.

Greetings

No, unfortunately.

I’m looking for a solution as well. I only have the billing infomation fields.

For anyone looking how to add a custom field to the ckeckout form, here is how i added a Comments textarea.

You field will also be added to the admin view of the order and the email notices.

Just paste this in your functions.php

/**
 * Add custom field to booking object post metabox
 *
 * @param object CMB2 object
 */
function uau_cmb2_order_customer_fields($cmb)
{

    $cmb->add_field(array(
        'name'       => __('Comments', 'ba-book-everything'),
        'id'         => 'order-comments',
        'type'       => 'textarea',
    ));

    return;
}
add_action('babe_cmb2_order_customer_fields', 'uau_cmb2_order_customer_fields', 10);

function add_customs_order_fields($output, $args)
{

    $comments = !empty($args['meta']['order-comments']) ? $args['meta']['order-comments'] : '';

    $output .= '<h3>' . __('Comments', 'ba-book-everything') . '</h3>';

    $output .= '<div class="address_fields_group input_group">
				        <div class="checkout-form-block">
				           <div class="checkout_form_input_field ' . (!empty($comments) ? 'checkout_form_input_field_content' : '') . '">
				               <label class="checkout_form_input_label">' . __('Comments', 'ba-book-everything') . '</label>
							   <textarea class="checkout_input_field" name="order-comments" id="order-comments" value="' . esc_attr($comments) . '"></textarea>
						   </div>
				        </div>
				      </div>';

    return $output;
}
add_filter('babe_checkout_after_contact_fields', 'add_customs_order_fields', 20, 2);

function sanitize_customs_order_fields($output, $arr)
{
    $output['order-comments'] = isset($arr['order-comments']) ? sanitize_text_field($arr['order-comments']) : '';
    return $output;
}
add_filter('babe_sanitize_checkout_vars', 'sanitize_customs_order_fields', 20, 2);

/**
 * Add checkout field titles
 */
function uau_babe_checkout_field_label($field_title, $field_name)
{
    if ($field_name === 'order-comments') {
        $field_title = __('Comments', 'ba-book-everything');
    }
    return $field_title;
}
add_filter('babe_checkout_field_label', 'uau_babe_checkout_field_label', 10, 2);

That’s it.

Thanks for that.

Hello, you can try this in the functions.php, made 4 extra fields:

add_filter('babe_checkout_args', 'customtheme_babe_checkout_args', 10, 2);
/**
 * Add checkout fields
 */
function customtheme_babe_checkout_args( $args_meta, $args ) {
    $args_meta['new_field'] = isset($args['meta']['new_field']) ? $args['meta']['new_field'] : '';
    $args_meta['second_field'] = isset($args['meta']['second_field']) ? $args['meta']['second_field'] : '';
    $args_meta['third_field'] = isset($args['meta']['third_field']) ? $args['meta']['third_field'] : '';
    $args_meta['fourth_field'] = isset($args['meta']['fourth_field']) ? $args['meta']['fourth_field'] : '';
    return $args_meta;
}
////////
add_filter('babe_checkout_field_label', 'customtheme_babe_checkout_field_label', 10, 2);
/**
 * Add checkout field title
 */
function customtheme_babe_checkout_field_label( $field_title, $field_name ) {
    if ($field_name === 'new_field'){
       $field_title = __('Hotel', 'textdomain');
    }
    if ($field_name === 'second_field'){
       $field_title = __('Second Field', 'textdomain');
    }
    if ($field_name === 'third_field'){
       $field_title = __('Third Field', 'textdomain');
    }
    if ($field_name === 'fourth_field'){
       $field_title = __('Fourth Field', 'textdomain');
    }
    return $field_title;
}
////////
add_filter('babe_checkout_field_required', 'customtheme_babe_checkout_field_required', 10, 2);
/**
 * Required tag for checkout field
*/
function customtheme_babe_checkout_field_required($required_tag, $field_name){
   if ($field_name === 'new_field' || $field_name === 'second_field' || $field_name === 'third_field' || $field_name === 'fourth_field'){
      $required_tag = 'required="required"';
   }
   return $required_tag;
}
add_filter('babe_sanitize_checkout_vars', 'customtheme_sanitize_checkout_vars', 10, 2);
/**
 * Add fields to sanitize checkout vars method
 */
function customtheme_sanitize_checkout_vars( $output, $arr ) {

    $output['new_field'] = isset($arr['new_field']) ? sanitize_text_field($arr['new_field']) : '';
    $output['second_field'] = isset($arr['second_field']) ? sanitize_text_field($arr['second_field']) : '';
    $output['third_field'] = isset($arr['third_field']) ? sanitize_text_field($arr['third_field']) : '';
    $output['fourth_field'] = isset($arr['fourth_field']) ? sanitize_text_field($arr['fourth_field']) : '';
    return $output;
}
