如何使用TCPDF将HTML转换为PDF？

Question

我会如何编写一个div（例如style="postion:absolute; width: 200px; height: 100px; border: solid 1px #000;"）并在其中输入一些文本？

Answer 1

下面的代码片段只显示了生成div的相关代码，并且假设您已经初始化了pdf文档并且使用了$ pdf作为句柄。此外，确切的尺寸（读取：像素位置/尺寸）不会直接转换为tcpdf，因此您可能需要稍微玩一下。请参阅TCPDF writeHTMLCell文档here。

$borderStyle=array(); 
$borderStyle['cap']='butt'; 
$borderStyle['color']=array(0,0,0); 
$borderStyle['dash']=0; 
$borderStyle['join']='';  
$borderStyle['phase']=0; 
$borderStyle['width']=1; 

$divHeight=100; 
$divWidth=200; 

$divXPosition=15; 
$divYPosition=80; 

$pdf->writeHTMLCell($divWidth, $divHeight, $divXPosition,$divYPosition,$html, $borderStyle); 

Answer 2

利用TCPDF库的的WriteHTML功能。

<?php 

require_once('tcpdf_include.php'); 
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false); 

$pdf->SetCreator(PDF_CREATOR); 
$pdf->SetAuthor('Nicola Asuni'); 
$pdf->SetTitle('TCPDF Example 049'); 
$pdf->SetSubject('TCPDF Tutorial'); 
$pdf->SetKeywords('TCPDF, PDF, example, test, guide'); 

$pdf->SetHeaderData(PDF_HEADER_LOGO, PDF_HEADER_LOGO_WIDTH, PDF_HEADER_TITLE.' 049', PDF_HEADER_STRING); 

]$pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN)); 
$pdf->setFooterFont(Array(PDF_FONT_NAME_DATA, '', PDF_FONT_SIZE_DATA)); 

$pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED); 

$pdf->SetMargins(PDF_MARGIN_LEFT, PDF_MARGIN_TOP, PDF_MARGIN_RIGHT); 
$pdf->SetHeaderMargin(PDF_MARGIN_HEADER); 
$pdf->SetFooterMargin(PDF_MARGIN_FOOTER); 

$pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM); 

$pdf->setImageScale(PDF_IMAGE_SCALE_RATIO); 

if (@file_exists(dirname(__FILE__).'/lang/eng.php')) { 
    require_once(dirname(__FILE__).'/lang/eng.php'); 
    $pdf->setLanguageArray($l); 
} 
$pdf->SetFont('helvetica', '', 10); 

$pdf->AddPage(); 


$html = '<h1>Test TCPDF Methods in HTML</h1> 
<h2 style="color:red;">IMPORTANT:</h2> 
<span style="color:red;">If you are using user-generated content, the tcpdf tag can be unsafe.<br /> 
You can disable this tag by setting to false the <b>K_TCPDF_CALLS_IN_HTML</b> constant on TCPDF configuration file.</span> 
<h2>write1DBarcode method in HTML</h2>'; 

$params = TCPDF_STATIC::serializeTCPDFtagParameters(array('CODE 39', 'C39', '', '', 80, 30, 0.4, array('position'=>'S', 'border'=>true, 'padding'=>4, 'fgcolor'=>array(0,0,0), 'bgcolor'=>array(255,255,255), 'text'=>true, 'font'=>'helvetica', 'fontsize'=>8, 'stretchtext'=>4), 'N')); 
$html .= '<tcpdf method="write1DBarcode" params="'.$params.'" />'; 

$params = TCPDF_STATIC::serializeTCPDFtagParameters(array('CODE 128', 'C128', '', '', 80, 30, 0.4, array('position'=>'S', 'border'=>true, 'padding'=>4, 'fgcolor'=>array(0,0,0), 'bgcolor'=>array(255,255,255), 'text'=>true, 'font'=>'helvetica', 'fontsize'=>8, 'stretchtext'=>4), 'N')); 
$html .= '<tcpdf method="write1DBarcode" params="'.$params.'" />'; 

$html .= '<tcpdf method="AddPage" /><h2>Graphic Functions</h2>'; 

$params = TCPDF_STATIC::serializeTCPDFtagParameters(array(0)); 
$html .= '<tcpdf method="SetDrawColor" params="'.$params.'" />'; 

$params = TCPDF_STATIC::serializeTCPDFtagParameters(array(50, 50, 40, 10, 'DF', array(), array(0,128,255))); 
$html .= '<tcpdf method="Rect" params="'.$params.'" />'; 
$pdf->writeHTML($html, true, 0, true, 0); 

$pdf->lastPage(); 
$pdf->Output('example_049.pdf', 'I');
