Passing Custom Fields to UltraCart During the Checkout

Introduction

This tutorial will explain how to pass custom fields to UltraCart during the checkout and then retrieve the information. Custom fields are primarily used to store identifiers from an external system to consume after an order is placed.

Understanding Custom Fields

UltraCart currently supports seven custom fields on a cart/order. The fields are named Custom Field 1 through Custom Field 7. The fields currently support the following amounts of data.

Field	Length
CustomField1	50 characters
CustomField2	50 characters
CustomField3	50 characters
CustomField4	50 characters
CustomField5	75 characters
CustomField6	50 characters
CustomField7	50 characters

Passing on a Buy Link

On a buy link you can pass the custom fields by appending:

&CustomField#=VALUE

to the buy link. The Advanced Buy Link builder under:

Main Menu Item Management Items [links]

will allow you to build up the link as shown below.

Passing custom field data from Buy Form code

The following example shows contains 2 custom fields". The first custom field (on line 4) is a hidden input field that passes "New Landing Page" into "CustomField1" to track that the sale came from the new landing page rather then default store location, and a second custom field "CustomField2" (line 10) which is storing the value for a field asking the customer "What breed of dog(s) do you have?"

Custom Field in Buy Form (Hidden Field)

<form method="post" action="https://ucsupport.ultracart.com/cgi-bin/UCEditor">
  <input type="hidden" name="merchantId" value="DEMO" />
  <input type="hidden" name="add" value="Bone" />
  <input type="hidden" name="CustomField1" value="New Landing Page" />
  <table class="uc-item-table">
    <tr class="uc-item-dog-breed-row">
      <td class="uc-item-dog-breed-label">What breed of dog(s) do you have?</td>
      <td class="uc-item-dog-breed-field">
        <input type="text" name="CustomField2" value="" />
      </td>
    </tr>
    <tr class="uc-item-qty-row">
      <td class="uc-item-qty-label">Qty</td>
      <td class="uc-item-qty-field">
        <input type="text" name="quantity" value="1" />
      </td>
    </tr>
    <tr class="uc-item-cost-row">
      <td class="uc-item-cost-label">Cost</td>
      <td class="uc-item-cost-value"><script type="text/javascript" src="https://ucsupport.ultracart.com/cgi-bin/UCPrice?MERCHANTID=DEMO&ITEM=BONE&output=Javascript"></script></td>
    </tr>
    <tr class="uc-item-submit-row">
      <td></td>
      <td>
        <input type="submit" name="submit" value="add to cart" />
      </td>
    </tr>
  </table>
</form>

Inserting the Custom Fields into the checkout

If you require the use of the custom fields to collect additional information from the customer during the checkout, you can insert the custom fields into the checkout.

<table><table id='CustomFields'>

<input type='text' class="ucFormField" style="width:315px" name="customField5"/>
</td>
</tr><tr>
<td>
<span class="ucColorSubHeader ucCommentsHeader">CustomField6 label text </span>
</td>
</tr>
<tr>

<input type='text' class="ucFormField" style="width:315px" name="customField6"/>
</td>
</tr><tr>

<span class="ucColorSubHeader ucCommentsHeader">CustomField7 label text </span>
</td>

</table>

The above HTML code would render into the single page checkout like this:

Seeing Custom Field Values in Web Interface

Whenever you see an order in the system you can click Edit Customer Information and then click the Other tab. The other tab will display the contents of the seven custom fields as shown below.

Using on the Receipt

The values of the custom fields can also be used in conversion scripts on the receipt. If you navigate to:

Main Menu Configuration Screen Branding Themes [edit] Conversion and Tracking

You can use tokens like [CustomField1] within your conversion HTML. These will be replaced with the actual value from the order.

Retrieving Back the Custom Fields

There are 3 ways to receive back the custom fields that you passed in.

Export Orders

A merchant can configure an export to collect the custom field values. Exports are configured under:

Main Menu Configuration Exporting Orders

Distribution Center API

This SOAP web service API is used by some third party fulfillment houses and shipping platforms to retrieve shipment information from UltraCart. You can read more about the Distribution Center Transport API here.

XML Postback

XML Postback is a method of communication whereby UltraCart notifies the merchant's web server of order activity by posting XML versions of the order to the merchant's server. You can read more about XML Postback here. XML Postback is configured under:

Main Menu Configuration XML Postback
