在 PHP 中使用 DOMPDF 的 PDF 页面中的标题

发布于 2024-12-05 18:36:51 字数 109 浏览 0 评论 0原文

我正在使用 DOMPDF 创建 PDF 文件。我有大量内容要提取为 PDF，我们需要在所有页面中添加一些标题。那么谁能告诉我如何在 PDF 中添加页眉和页脚，以便使用 DOMPDF 在所有页面中显示页眉。

在 0.6.0 代码中，您将能够使用 HTML+CSS 生成页眉和页脚。与使用内联 PHP 相比，有一些限制（例如，还没有 PAGE_COUNT 占位符），因此这是否可行取决于您的需求。

以下代码将生成一个带有页眉和页脚的两页文档：

<html>
<head>
  <style>
    @page { margin: 180px 50px; }
    #header { position: fixed; left: 0px; top: -180px; right: 0px; height: 150px; background-color: orange; text-align: center; }
    #footer { position: fixed; left: 0px; bottom: -180px; right: 0px; height: 150px; background-color: lightblue; }
    #footer .page:after { content: counter(page, upper-roman); }
  </style>
<body>
  <div id="header">
    <h1>Widgets Express</h1>
  </div>
  <div id="footer">
    <p class="page">Page </p>
  </div>
  <div id="content">
    <p>the first page</p>
    <p style="page-break-before: always;">the second page</p>
  </div>
</body>
</html>

您也可以使用组合如果您需要访问某些缺少的功能，请选择这两种样式。使用 page_text 方法添加的 PDF 对象和文本呈现在 HTML 内容之上。

In the 0.6.0 code you will be able to use HTML+CSS to generate headers and footers. There are a few limitations when compared to using inline PHP (e.g. no PAGE_COUNT placeholder yet), so whether or not this is viable depends on your needs.

The following code will produce a two-page document with a header and footer:

<html>
<head>
  <style>
    @page { margin: 180px 50px; }
    #header { position: fixed; left: 0px; top: -180px; right: 0px; height: 150px; background-color: orange; text-align: center; }
    #footer { position: fixed; left: 0px; bottom: -180px; right: 0px; height: 150px; background-color: lightblue; }
    #footer .page:after { content: counter(page, upper-roman); }
  </style>
<body>
  <div id="header">
    <h1>Widgets Express</h1>
  </div>
  <div id="footer">
    <p class="page">Page </p>
  </div>
  <div id="content">
    <p>the first page</p>
    <p style="page-break-before: always;">the second page</p>
  </div>
</body>
</html>

You could also use a combination of the two styles if you needed access to some of the missing functionality. PDF objects and text added using the page_text method render on top of the HTML content.

DOMPDF wiki 上有一个常见问题解答条目：有办法吗添加页眉和页脚或页码？。

因此，您可以将以下“内联 PHP”片段添加到您的 HTML 输入中（添加类似的 page_text - 调用页脚）：

<script type="text/php">
    if ( isset($pdf) ) {
        $font = Font_Metrics::get_font("helvetica", "bold");
        $pdf->page_text(72, 18, "Header: {PAGE_NUM} of {PAGE_COUNT}",
                        $font, 6, array(0,0,0));
    }
</script>

如果您想在调用方实现此功能（即直接在 PHP 代码中），您必须调用DOMPDFS 的 get_canvas() 方法返回底层 PDF 渲染器，允许您调用 page_text 方法，如上例所示。让我向您展示我的意思：

// your dompdf setup        
$dompdf = new DOMPDF();

$dompdf->load_html($html);
$dompdf->render();

// add the header
$canvas = $dompdf->get_canvas();
$font = Font_Metrics::get_font("helvetica", "bold");

// the same call as in my previous example
$canvas->page_text(72, 18, "Header: {PAGE_NUM} of {PAGE_COUNT}",
                   $font, 6, array(0,0,0));

最终您必须在 load_html 之后调用 page_text （只需尝试一下）。

There is a FAQ entry on the DOMPDF wiki: Is there a way to add headers and footers or page numbers?.

So you can either add the following "inline PHP"-snippet to your HTML-input (add a similar page_text-call for your footer):

<script type="text/php">
    if ( isset($pdf) ) {
        $font = Font_Metrics::get_font("helvetica", "bold");
        $pdf->page_text(72, 18, "Header: {PAGE_NUM} of {PAGE_COUNT}",
                        $font, 6, array(0,0,0));
    }
</script>

If you rather want to implement this on your caller-side (meaning in the PHP code directly) you have to call the DOMPDFS's get_canvas()-method which returns the underlying PDF-Renderer which allows you to call the page_text method like in the example above. Let me show you what I mean:

// your dompdf setup        
$dompdf = new DOMPDF();

$dompdf->load_html($html);
$dompdf->render();

// add the header
$canvas = $dompdf->get_canvas();
$font = Font_Metrics::get_font("helvetica", "bold");

// the same call as in my previous example
$canvas->page_text(72, 18, "Header: {PAGE_NUM} of {PAGE_COUNT}",
                   $font, 6, array(0,0,0));

Eventually you have to call page_text after load_html (just try it out).

如果你想得到类似的东西：

定义文档的页眉、页脚和内容如下：

<html>
    <head>
        <style>
            @page {
                margin: 100px 25px;
            }

            header {
                position: fixed;
                top: -60px;
                height: 50px;
                background-color: #752727;
                color: white;
                text-align: center;
                line-height: 35px;
            }

            footer {
                position: fixed;
                bottom: -60px;
                height: 50px;
                background-color: #752727;
                color: white;
                text-align: center;
                line-height: 35px;
            }
        </style>
    </head>
    <body>
        <header>
            Header
        </header>

        <footer>
            Footer
        </footer>

        <main>
            <!-- Your main content -->
        </main>
    </body>
</html>

If you want to get something similar to:

Define as follows, header, footer and content of your document:

<html>
    <head>
        <style>
            @page {
                margin: 100px 25px;
            }

            header {
                position: fixed;
                top: -60px;
                height: 50px;
                background-color: #752727;
                color: white;
                text-align: center;
                line-height: 35px;
            }

            footer {
                position: fixed;
                bottom: -60px;
                height: 50px;
                background-color: #752727;
                color: white;
                text-align: center;
                line-height: 35px;
            }
        </style>
    </head>
    <body>
        <header>
            Header
        </header>

        <footer>
            Footer
        </footer>

        <main>
            <!-- Your main content -->
        </main>
    </body>
</html>

您需要此代码，希望对您

有所帮助...

# Instanciamos un objeto de la clase DOMPDF.
$dompdf = new DOMPDF();

# Definimos el tamaño y orientación del papel que queremos.
# O por defecto cogerá el que está en el fichero de configuración.
$dompdf->set_paper("Letter", "portrait");

# Cargamos el contenido HTML.
$dompdf->load_html(utf8_decode($html));

# Renderizamos el documento PDF.
$dompdf->render();

#Esto es lo que imprime en el PDF el numero de paginas
$canvas = $dompdf->get_canvas();
$footer = $canvas->open_object();
$w = $canvas->get_width();
$h = $canvas->get_height();
$canvas->page_text($w-60,$h-28,"Página {PAGE_NUM} de {PAGE_COUNT}", Font_Metrics::get_font('helvetica'),6);
$canvas->page_text($w-590,$h-28,"El pie de página del lado izquiero, Guadalajara, Jalisco C.P. XXXXX Tel. XX (XX) XXXX XXXX", Font_Metrics::get_font('helvetica'),6);

$canvas->close_object();
$canvas->add_object($footer,"all");

# Enviamos el fichero PDF al navegador.
//$dompdf->stream('FicheroEjemplo.pdf');

# Para grabar en fichero en ruta especifica
$output = $dompdf->output();
file_put_contents('ejemplo.pdf',$output);

 #Liberamos

才将 Blade 与类似的内容一起使用

<!doctype html>
<html lang="en">
<head>
        <style>
header { position: absolute; top: -70px; left: 0px; right: 0px; height: 150px; margin-bottom: 10em }
        </style>
</head>
<body>
       <header>
            <table border="0" width="100%" style="font-size:1em" class="tb-header">
                <tr>
                    <td width="83%" class="left-align" >
                        <tr>
                            <td>
                                <span class="invoice-number mr-1" style="font-size:1em">Purchase Invoice # {{ $data->code }}</span>
                            </td>
                        </tr>
                        <tr>
                            <td style="margin-top: -2px;">
                                <small style="font-size:1em">Diajukan: {{ date('d/m/y',strtotime($data->post_date)) }}</small>
                            </td>
                        </tr>
                        <tr>
                            <td>
                                <h5 style="margin-top: -2px">Purchase Invoice</h5>
                            </td>
                        </tr>
                                
                        
                    </td>
                    <td width="33%" class="right-align">
                        
                        
                   
                    </td>
                    
                    <td width="34%" class="right-align">

                </tr>
                
            </table>
            <hr style="border-top: 3px solid black; margin-top:-2%">
        </header>
<main>
</main>
</body>

仅在每个 pdf 中呈现此标头后，
请记住！标签标头必须位于主体标签主之前

use blade only with something like this

<!doctype html>
<html lang="en">
<head>
        <style>
header { position: absolute; top: -70px; left: 0px; right: 0px; height: 150px; margin-bottom: 10em }
        </style>
</head>
<body>
       <header>
            <table border="0" width="100%" style="font-size:1em" class="tb-header">
                <tr>
                    <td width="83%" class="left-align" >

                            <td>

                        </tr>
                        <tr>

                            </td>
                        </tr>
                        <tr>
                            <td>
                                <h5 style="margin-top: -2px">Purchase Invoice</h5>

                    </td>
                    <td width="33%" class="right-align">
                        
                        
                   
                    </td>
                    
                    <td width="34%" class="right-align">

                </tr>
                
            </table>
            <hr style="border-top: 3px solid black; margin-top:-2%">
        </header>
<main>
</main>
</body>

after this header will be rendered in each pdf
Remember!tag header must be on the body before the tag main
