使用 DomPDF 创建发票 PDF


Using DomPDF to create invoice PDF

指向我们网络服务器上发票的示例链接:

http://billing/view/invoice?id=1

这将在浏览器中显示发票。

为了将其另存为 PDF,我尝试:

<?php
function file_get_contents_curl($url) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_AUTOREFERER, TRUE);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);       
    $data = curl_exec($ch);
    curl_close($ch);
    return $data;
}
require_once("dompdf/dompdf_config.inc.php");
  $dompdf = new DOMPDF();
  $invoice = file_get_contents_curl('view/invoice?id=1');
  $dompdf->load_html($invoice);
  $dompdf->set_paper('a4');
  $dompdf->render();
  $dompdf->stream("dompdf_out.pdf", array("Attachment" => false));
  exit(0);
?>

这将显示空白页,没有发票或 PDF。

如果我改变

  $invoice = file_get_contents_curl('view/invoice?id=1');
  $dompdf->load_html($invoice);

  $invoice = "Hello";
  $dompdf->load_html($invoice);

然后它显示一个包含"Hello"的 PDF,因此捕获动态 PHP 发票似乎是一个问题。

错误报告显示:

Warning: file_get_contents(view/order.php?id=1432923): failed to open stream: No error in C:'inetpub'wwwroot'billing'test.php on line 6

尝试在以下位置添加完整的网址:

$invoice = file_get_contents_curl('http://...view/invoice?id=1');
