我正在为餐厅使用礼券脚本，以便人们可以购买礼券。该脚本捕获所有需要的信息并通过 AIM 方法将其发送到 Authorize.net。餐厅经理收到来自 Authorize.net 的电子邮件传输，其中包含交易信息。
所有主要字段都被传递到 Authorize.net。但是，我们称之为“商家定义的字段”的字段并没有出现在 Authorize.net 电子邮件传输中。我知道有一种方法可以将这些字段引用为 MDF 字段，但我无法弄清楚语法。
有人可以帮我弄清楚我遗漏了哪些行吗？
这是捕获相关字段的表单：
<form method="POST" action="cart.php">
<fieldset>
<div class="form-divider">
<label>Amount</label>
<select name="amount">
<?php for($i=5;$i<101;$i=$i+5){ ?>
<option value="<?php echo $i; ?>">$<?php echo $i; ?></option>
<?php } ?>
</select>
</div>
<div class="form-divider">
<label>Will gift certificate be mailed directly to the recipient?</label>
<input name="gift" type="radio" value="1" onclick="$('#gift-options').show();" />
<label>Yes</label>
<input name="gift" type="radio" value="0" checked="checked" onclick="$('#gift-options').hide();" />
<label>No</label>
</div>
<div id="gift-options">
<div class="col1">
<div class="form-divider">
<label>To</label>
<input name="gift-to" type="text" size="20" />
</div>
<div class="form-divider">
<label>From</label>
<input name="gift-from" type="text" size="20" />
</div>
</div>
<div class="col2">
<div class="form-divider">
<label>Ship To Address</label>
<textarea name="gift-address" style="width: 200px; height: 50px;"></textarea>
</div>
<div class="form-divider">
<label>Gift Message</label>
<textarea name="gift-message" style="width: 200px; height: 50px;"></textarea>
</div>
</div>
</div>
<div class="form-divider">
<label>Quantity</label>
<input name="quantity" type="text" value="1" />
</div>
<input type="hidden" name="action" value="add" />
</fieldset>
<input type="submit" value="Next Step" class="button" />
</form>
这是“结帐”代码，它收集实际发送到 Authorize.net 的数据：
