PHP+html网页转pdf

Question

我被这件事困住了，不知道该怎么办 do.I 搜索了很多次，并了解了 fpdf、html2pdf、tcpdf。

我正在创建一张发票，其中我使用了 html 和 php code.I 想要以 pdf 格式显示该数据想要将整个页面转换为 pdf 并打印并保存 it.But 我不知道要做什么 do.I 是新手，了解不多。

尝试了一些代码，但我只得到 html 文本，因为输出还需要 php 数据。

这是发票网页。

代码： index.php

<?php
if(!isset($_POST['submit']))
{
?>
<form method="post" action=''>
    <div id="page-wrap">

        <textarea id="header" name="text" disabled="disabled">INVOICE</textarea>

        <div id="identity">
          <textarea name="address" id="address" disabled="disabled" style="background-color:#FFF;color:#000">Address</textarea>
          <div id="logo">
          <img id="image" src="images/logo.png" alt="logo" /></div>
        </div>

        <div style="clear:both"></div>

        <div id="customer">

           <!-- <textarea id="customer-title" disabled="disabled" style="background-color:#FFF;color:#000">Widget Corp.

这是转换的输出。

您可以使用 tcpdf 从 html 渲染 pdf。它提供了更大的灵活性 https://tcpdf.org/examples/

查看此代码，这将生成虚拟发票。

   <?php 

function generateInvoice(){
$invoice_no = 0001;

require_once('tcpdf/tcpdf.php');
class MYPDF extends TCPDF 
{
    public function Header() {
    }


    // Page footer
    public function Footer() {
        // Position at 15 mm from bottom
        $this->SetY(-15);
        // Set font
        $this->SetFont('helvetica', 'I', 12);
    }

}

// create new PDF document
$pdf = new MYPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
// set header and footer fonts
$pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN));
$pdf->setFooterFont(Array(PDF_FONT_NAME_DATA, '', PDF_FONT_SIZE_DATA));

// set default monospaced font
$pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED);

// set margins
$pdf->SetMargins(0, 0, 0);
$pdf->SetHeaderMargin(0);
$pdf->SetFooterMargin(PDF_MARGIN_FOOTER);

// set auto page breaks
$pdf->SetAutoPageBreak(True, 0);

// set image scale factor
$pdf->setImageScale(PDF_IMAGE_SCALE_RATIO);

// set some language-dependent strings (optional)
if (@file_exists(dirname(__FILE__).'/lang/eng.php')) {
    require_once(dirname(__FILE__).'/lang/eng.php');
    $pdf->setLanguageArray($l);
}

// ---------------------------------------------------------

//set custom font
//$fontname = TCPDF_FONTS::addTTFfont('OpenSans-Semibold.ttf', 'TrueTypeUnicode', '',12);
// use the font
$pdf->SetFont($fontname, '', 12, '', false);

// add a page
$pdf->AddPage();

$pdf->setFontSize(40);

$pdf->Write(0, 'Company', '', 0, 'C', true, 0, false, false, 0);


$pdf->setFontSize(12);
