不少使用zen cart的朋友发现zen cart的系统默认定单号并不一定是大家想要的，很多人希望通过定单时间来确定不同的定单号以方便管理和使用，这里发布下目前适合1.38版本的定单时间与随机数字结合产生定单号的方法，在 includesclassesorder.php 里需要做出如下的代码调整，注意:：修改前请一定要备份好数据库，以防出现调整错误。

具体方法，在order.php里：

function create($zf_ot_modules, $zf_mode = 2) {

global $db;

$t1 = date(ymd);

srand ((float) microtime() * 10000000);

$input = array (1, 2, 3, 4, 5, 6, 7, 8, 9, 0);

$rand_keys = array_rand ($input, 2);

//$t1 = $input[$rand_keys[0]];

$t2 = $input[$rand_keys[1]];

$t3 = rand(0,9);

$ordernum = $t1.$t2.$t3;

if ($this->info['total'] == 0) {

if (default_zero_balance_orders_status_id == 0) {

$this->info['order_status'] = default_orders_status_id;

} else {

$this->info['order_status'] = default_zero_balance_orders_status_id;

}

}

if ($_session['shipping'] == ‘free_free’) {

$this->info['shipping_module_code'] = $_session['shipping'];

}

$sql_data_array = array(’orders_id’ => $ordernum,

‘customers_id’ => $_session['customer_id'],

‘customers_name’ => $this->customer['firstname'] . ‘ ‘ . $this->customer['lastname'],

‘customers_company’ => $this->customer['company'],

‘customers_street_address’ => $this->customer['street_address'],

‘customers_suburb’ => $this->customer['suburb'],

‘customers_city’ => $this->customer['city'],

‘customers_postcode’ => $this->customer['postcode'],

‘customers_state’ => $this->customer['state'],

‘customers_country’ => $this->customer['country']['title'],

‘customers_telephone’ => $this->customer['telephone'],

‘customers_email_address’ => $this->customer['email_address'],

‘customers_address_format_id’ => $this->customer['format_id'],

‘delivery_name’ => $this->delivery['firstname'] . ‘ ‘ . $this->delivery['lastname'],

‘delivery_company’ => $this->delivery['company'],

‘delivery_street_address’ => $this->delivery['street_address'],

‘delivery_suburb’ => $this->delivery['suburb'],

‘delivery_city’ => $this->delivery['city'],

‘delivery_postcode’ => $this->delivery['postcode'],

‘delivery_state’ => $this->delivery['state'],

‘delivery_country’ => $this->delivery['country']['title'],

‘delivery_address_format_id’ => $this->delivery['format_id'],

‘billing_name’ => $this->billing['firstname'] . ‘ ‘ . $this->billing['lastname'],

‘billing_company’ => $this->billing['company'],

‘billing_street_address’ => $this->billing['street_address'],

‘billing_suburb’ => $this->billing['suburb'],

‘billing_city’ => $this->billing['city'],

‘billing_postcode’ => $this->billing['postcode'],

‘billing_state’ => $this->billing['state'],

‘billing_country’ => $this->billing['country']['title'],

‘billing_address_format_id’ => $this->billing['format_id'],

‘payment_method’ => (($this->info['payment_module_code'] == ” and $this->info['payment_method'] == ”) ? payment_method_gv : $this->info['payment_method']),

‘payment_module_code’ => (($this->info['payment_module_code'] == ” and $this->info['payment_method'] == ”) ? payment_module_gv : $this->info['payment_module_code']),

’shipping_method’ => $this->info['shipping_method'],

’shipping_module_code’ => (strpos($this->info['shipping_module_code'], ‘_’) > 0 ? substr($this->info['shipping_module_code'], 0, strpos($this->info['shipping_module_code'], ‘_’)) : $this->info['shipping_module_code']),

‘coupon_code’ => $this->info['coupon_code'],

‘cc_type’ => $this->info['cc_type'],

‘cc_owner’ => $this->info['cc_owner'],

‘cc_number’ => $this->info['cc_number'],

‘cc_expires’ => $this->info['cc_expires'],

‘date_purchased’ => ‘now()’,

‘orders_status’ => $this->info['order_status'],

‘order_total’ => $this->info['total'],

‘order_tax’ => $this->info['tax'],

‘currency’ => $this->info['currency'],

‘currency_value’ => $this->info['currency_value'],

‘ip_address’ => $_session['customers_ip_address'] . ‘ - ‘ . $_server['remote_addr']

);

zen_db_perform(table_orders, $sql_data_array);

$insert_id = $ordernum;

// $insert_id = $db->insert_id();

这样以来，一个较为完善的根据顾客下单时间与系统随机数生成的定单号即生成了，有朋友说在1.38a貌似有bug和不完善的地方，我这还没来的及看到，ps:默认其实我是在1.37下改进的，但1.38的版本里关于order.php相关函数无多大变化，这里顺推应该可以在1.38下正常使用的。
