将变量从html传递到pdf

我使用PHP和PDFcrowd.com将html字符串转换为pdf。下面是我打电话的控制器。这将加载invoice.download.php 

$date = "january";
mysqli_query($connection->dbconn, "UPDATE monthly_visitors SET '$date' = 0");

这是我的invoice_download.php页面

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);
}

我知道我不能在html字符串里面使用php。我如何在生成的pdf中显示这些变量？用户永远不会看到invoice_download页面。他们点击“下载发票”的页面将保留当前页面，发票将下载。

我还在html字符串中有一个表，我需要循环显示所有行项目。我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。

我们可以在控制器本身内创建这些html，而不是在你提到用户不会看到该页面时创建一个新视图。根据我的看法，你在这里提到的视图页面上几乎没有错误。以下是更正。我仍然可能有错误，但你可能知道你犯了什么错误。您可以使用像＃39;。＆＃39;这样的字符串运算符。或者＆＃39;。=＆＃39;在哪里我们需要e.x。

如果php代码是

<?php
$html = '<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>';
if($test === 'yes'){
$html .= '<h4>Yesy it works</h4>';
}
else
{
$html .= 'sorry'
}
$html .= '</body>
</html>';
echo $html;
?>

所以上面会做的是如果编码为真，输出代码就像

<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>
<h4>Yesy it works</h4>
</body>
</html>

根据我的知识修正后的代码就像

<?php
$orderNumber = @$quotes[0]->orderNumber;
$customerId = @$quotes[0]->customerId; 
$html = '
<!DOCTYPE html>
<html>
<head>
