使用dompdf將頁面轉換爲PDF

我想使用dompdf將PHP頁面轉換爲PDF，但我不確定最好的方式來做到這一點。我已經寫了我的網頁我怎麼想它在標準的HTML/PHP提交，並希望它顯示像這樣，就像一個PDF：使用dompdf將頁面轉換爲PDF

Desired output

我的PHP代碼如下。我相信我需要將我的代碼放入$html變量中以將其解析爲dompdf，但我是一位PHP新手，所以希望得到一些幫助，以瞭解實現此目的的最佳方式。顯然，頁面的樣式都是從外部CSS文件中引入的，所以我不確定這是否是一個問題？

    include("checklog.php"); 
    require_once("watchlist-controller.php"); 
    require_once("dompdf/dompdf_config.inc.php");

更新

基於BrianS的評論（謝謝！），我的新代碼看起來像下面，但試圖查看監視列表中時，我現在得到的只是一個普通的空白頁。我已經測試了它沒有dompdf的東西，並且頁面顯示完美，顯示了我希望它顯示的所有信息，並正確顯示。我也用CSS替換了LESS文件並刪除了所有的JS。

另外，如果有幫助，把錯誤報告讓我以下：

試試這個：https://github.com/mreiferson/php-wkhtmltox – GBD 2013-04-28 11:57:35

一些一般建議：如果您只是將輸出發送到瀏覽器，那麼運行代碼並不會產生什麼影響。在這種情況下，您會得到一個錯誤，您可以使用它來嘗試找出代碼中缺少的內容。錯誤並不總是準確地報告問題的根源，但在大多數情況下，它們會爲您提供所需的信息，以糾正任何語法問題。 – BrianS 2013-04-29 16:23:38

我會建議使用WKHTMLTOPDF它提供了很多的選擇

有多種方式做你想做的事。您的當前邏輯應該可行，但語法不太正確。但是，如果您想堅持使用當前的結構，則可以使用輸出緩衝。

<?php 
include("checklog.php"); 
require_once("watchlist-controller.php"); 
require_once("dompdf/dompdf_config.inc.php"); 
ob_start(); 
?> 

<html>...</html> 

<?php 
$html = ob_get_clean(); 
$dompdf = new DOMPDF(); 
$dompdf->load_html($html); 
$dompdf->render(); 
$dompdf->stream("sample.pdf"); 
?>

鏈接樣式表很好。 JavaScript不是，dompdf不支持客戶端JS。所以如果你的LESS樣式表是必需的，你將不得不將它轉換爲標準的CSS。

嗨，謝謝你的幫助！我很感激協助。我已經做出了您所建議的更改，但是現在我在嘗試下載PDF時正在獲得純白色的頁面。根據您的評論，我已更新了原始文章/新代碼。 – 2013-04-29 18:37:45

編輯：還添加錯誤報告消息更新後發佈進一步澄清。 – 2013-04-29 19:08:36

大多數警告/通知與dompdf沒有任何關係。你所看到的似乎是一個導致你的MySQL查詢失敗的缺失變量。始終檢查查詢的狀態。例如，'$ query = mysql_query（...）; if（$ query）{...} else {...}'。 – BrianS 2013-04-29 21:23:19

使用下面的簡單代碼。

require_once 'dompdf/autoload.inc.php'; 
use Dompdf\Dompdf; 
$dompdf = new Dompdf(); 

$html = 'Insert full HTML content'; 
$dompdf->loadHtml($html); 
$dompdf->setPaper('A4', 'landscape'); 
$dompdf->render(); 
$dompdf->stream("codexworld",array("Attachment"=>0));
