如何在woocommerce结帐中设置默认值

Question

我刚刚使用以下代码创建了一个包含订单审核的页面

<form name="checkout" method="post" class="checkout woocommerce-checkout" action="<?php echo esc_url( $get_checkout_url ); ?>" enctype="multipart/form-data">
<h3 id="order_review_heading"><?php _e( 'Your order', 'woocommerce' ); ?></h3>

    <?php do_action( 'woocommerce_checkout_before_order_review' ); ?>

    <div id="order_review" class="woocommerce-checkout-review-order">
        <?php do_action( 'woocommerce_checkout_order_review' ); ?>
    </div>

    <?php do_action( 'woocommerce_checkout_after_order_review' ); ?></div>
    </form>
    <?php do_action( 'woocommerce_after_checkout_form', $checkout ); ?>
      </div>

我已将默认值设置function.php如下:

function overridefields($fields)
{
    global $wpdb;
    session_start();
    //print_r($_SESSION);
    //$fields['billing']['billing_delivery_date'] = array('label'=>'Delivery Date','Placeholder'=>'Date','required'=>'false','readonly'=>'true');
    $select_r = $wpdb->get_results("select * from `register` where `userid`='18'");
    //print_r($select_r);
    $fields['billing']['billing_first_name']['default']=$_SESSION['f_name'];
    $fields['billing']['billing_last_name']['default']=$_SESSION['l_name'];
    $fields['billing']['billing_address_1']['default']=$_SESSION['address'];
    $fields['billing']['billing_address_2']['default']='';
    $fields['billing']['billing_city']['default']=$_SESSION['city'];
    //$fields['billing']['billing_state']['default']=$select_r[0]->state;
    $fields['billing']['billing_email']['default']=$_SESSION['email'];
    $fields['billing']['billing_phone']['default']=$_SESSION['phone'];
    $fields['billing']['billing_postcode']['default']=$_SESSION['pincode'];
    //$fields['billing']['billing_delivery_date']['default']=$_SESSION['delivdate'];
    return $fields;
}
add_filter('woocommerce_checkout_fields','overridefields');

但是当我点击结账按钮然后我收到了错误

Country is a required field. First Name is a required field. Last Name is a required field. Address is a required field. Town / City is a required field. State / County is a required field. Postcode / Zip is a required field. Email Address is a required field. Phone is a required field.

如何在woocommerce结帐页面中设置默认值

Answer 1

我找到的代码可能很有用:

<?php
  add_filter( 'woocommerce_checkout_fields' , 'default_values_checkout_fields' );
  function default_values_checkout_fields( $fields ) {
    // You can use this for postcode, address, company, first name, last name and such. 
    $fields['billing']['billing_city']['default'] = 'SomeCity';
    $fields['shipping']['shipping_city']['default'] = 'SomeCity';
         return $fields;
  }
?>

然后使用CSS隐藏输入.
