【问题描述】：
我正在使用 PHP 和 PDFcrowd.com 将 html 字符串转换为 pdf。下面是我调用的控制器。这将加载 invoice.download.php
function pdf() {
$currentUser = $this->session->userdata("login_id");
$query = ParseUser::query();
$query->equalTo("objectId", $currentUser);
$this->data['company_data'] = $query->find();
try {
$objectUser = $query->get($currentUser);
$file = $objectUser->get("logo");
} catch (ParseException $ex) {
}
if ($file != NULL) {
$imageURL = $file->getURL();
} else {
$imageURL = "index.php/assets/images/fourcards.jpg";
}
$objectId = $this->input->get("object_id");
$query = new ParseQuery('Quotes');
$query->equalTo("objectId", $objectId);
$this->data['quotes'] = $query->find();
try {
$object = $query->get($objectId);
$customerId = $object->get("customerId");
$taxRate = $object->get("tax");
$shipping = $object->get("shipping");
$priceString = $object->get("price");
$priceNumber = preg_replace("/[\$,]/", '', $priceString);
$qtyArray = $object->get("qty");
} catch (ParseExeption $ex) {
}
$unitPrice = floatval($priceNumber);
$qty = $qtyArray[0];
$unitPriceTotal = $unitPrice * $qty;
if($taxRate == 1){
$tax = 0;
$this->data["tax"] = $tax;
} else {
$taxDecimal = $taxRate/100;
$tax = $taxDecimal * $unitPriceTotal;
}
$shippingTotal = $shipping;
$subTotal = $unitPriceTotal;
$totalPrice = $unitPriceTotal;
$taxTotal = $tax;
$grandTotal = $totalPrice + $taxTotal + $shippingTotal;
$this->data["shippingTotal"] = number_format($shippingTotal, 2, '.', ',');
$this->data["totalPrice"] = number_format($totalPrice, 2, '.', ',');
$this->data["taxTotal"] = number_format($taxTotal, 2, '.', ',');
$this->data["grandTotal"] = number_format($grandTotal, 2, '.', ',');
$this->data["qty"] = $qty;
$this->data["unitPrice"] = number_format($unitPrice, 2, '.', ',');
$this->data["subTotal"] = number_format($subTotal, 2, '.', ',');
$this->data["tax"] = number_format($tax, 2, '.', ',');
$this->data["logo"] = $imageURL;
$query = new ParseQuery("Customers");
$query->equalTo("userId", $this->session->userdata('login_id'));
$query->limit(900000);
$this->data['customer'] = $query->find();
$this->load->library('Pdf');
$this->load->view('completed_orders/invoice_download', $this->data);
}
这是我的 invoice_download.php 页面

我知道我不能在 html 字符串中使用 php。我将如何让这些变量显示在生成的 pdf 中？用户永远不会看到 invoice_download 页面。他们点击“下载发票”的页面将保持当前页面并下载发票。
我在 html 字符串中还有一个表格，我需要循环显示所有行项目。我也需要能够重新创建它，因为这也是 php 代码。任何帮助深表感谢。
