Question

我正在尝试使用FPDF生成PDF文件，这是我第一次尝试它。

我有最新的FPDF文件，并且还设置了WriteHTML插件。下面的代码正在处理，直到WriteHTML部分位于最底层。我收到错误＆＃34;警告：在第796行＆＃34; /home4/fwall/public_html/fpdf/fpdf.php中除以零。当我查看FPDF.php的第796行时，我发现了这个：

// Output text in flowing mode
    $cw = &$this->CurrentFont['cw'];
    $w = $this->w-$this->rMargin-$this->x;
    $wmax = ($w-2*$this->cMargin)*1000/$this->FontSize; // <--LINE 796
    $s = str_replace("\r",'',$txt);
    $nb = strlen($s);
    $sep = -1;
    $i = 0;
    $j = 0;
    $l = 0;
    $nl = 1;

如果我添加条件语句，则按以下方式添加：

if ($this->FontSize != 0) {
$wmax = ($w-2*$this->cMargin)*1000/$this->FontSize; // <--LINE 796
}

我可以让错误消失，但我知道这不是正确的。有没有人在我的代码中看到会导致此错误的错误？

WriteHTML add-on是一个名为PDF_HTML的类，它扩展了原始FPDF。要使用附加组件功能，您必须实例化子类并使用它：

$pdfhtml=new PDF_HTML();

您不需要父类的其他实例（$pdf）。删除它并将$pdf的所有引用更改为$pdfhtml，您就可以了：

<?php
define('FPDF_FONTPATH', '../Classes/FPDF/font/');
require ('../Classes/FPDF/fpdf.php');
require ('writeHtml.php');


//create a PDF_HTML object
$pdfhtml=new PDF_HTML();

//set document properties
$pdfhtml->SetAuthor('Author Name');
$pdfhtml->SetTitle('PRESS RELEASE - NAME OF SHOW');

//set font for the entire document
$pdfhtml->SetFont('Helvetica','B',10);
$pdfhtml->SetTextColor(0,0,0);

//set up a page
$pdfhtml->AddPage('P');
// $pdfhtml->SetDisplayMode(real,'default'); //<-- commented this line, what is real?

//display the top block
$contact = 'Contact Name';
$addline1 = '4002 2nd Ave NE, #2';
$addline2 = 'Address Line 2';
$cityzip = 'Seattle, WA 98105';
$pdfhtml->Cell(0, 4, 'PRESS RELEASE', 0, 0, 'L');
$pdfhtml->Cell(0, 4, 'FOR IMMEDIATE RELEASE', 0, 1, 'R');
$pdfhtml->Cell(0, 4, 'CONTACT: '.$contact, 0, 0, 'L');
$pdfhtml->Cell(0, 4, 'KILL DATE: August 1, 2014', 0, 1, 'R');
$pdfhtml->Cell(0, 4, $addline1, 0, 1, 'L');
$pdfhtml->Cell(0, 4, $addline2, 0, 1, 'L');
$pdfhtml->Cell(0, 4, $cityzip, 0, 1, 'L');


//display the title
$pdfhtml->SetFontSize(20);
$pdfhtml->Cell(0,10,'PRESS RELEASE TITLE',0,1,'C',0);

//display the sub-title
$pdfhtml->SetFontSize(16);
$pdfhtml->Cell(0,10,'The Subtitle',0,1,'C',0);

//display the italic summary
$pdfhtml->SetXY(10,55);
$pdfhtml->SetFont('Helvetica','I',10);
$summary = 'SEATTLE - Theatre Off Jackson presents SPF 8, the annual exhibition of solo    performance.

$pdfhtml->MultiCell(0, 4, $summary , 0, 'J');

//display the main content
$pdfhtml->SetFont('Helvetica','',10);

$maincontent = '
    First line.
    Second Line?
    <ul>
        <li>
        Item 1
        </li>
    </ul>
    ';
$pdfhtml->WriteHTML($maincontent);


//Output the document
$pdfhtml->Output('example1.pdf','I');

请注意，我更改了顶部的包含路径。我还评论了您呼叫SetDisplayMode的行。

Answer 2

你可能有一些元素，例如你的pdf html中的不平衡。某些元素可能尚未关闭或启动。找到这个问题我花了2天时间。

使用FPDF + WriteHTML附加组件进行零错误划分
