Question

我使用TCPDF生成pdf报告。我需要自定义页眉和页脚，因此我扩展了原始类以覆盖官方文档（https://tcpdf.org/examples/example_002.phps）中建议的页眉和页脚方法。

您在这里是代码：

class AppPdf extends \TCPDF {

    CONST LOGO_PATH =  '/../../../public_html/public/images/logo-big.png';

    private $xLogo;
    private $yLogo;
    private $wLogo;

    public function __construct($orientation='P', $unit='mm', $format='A4', $unicode=true, $encoding='UTF-8', $diskcache=false, $pdfa=false, $xLogo = 8, $yLogo = 0, $wLogo = 50) {
        parent::__construct($orientation, $unit, $format, $unicode, $encoding, $diskcache, $pdfa);

        $this->xLogo = $xLogo;
        $this->yLogo = $yLogo;
        $this->wLogo = $wLogo;
    }

    public function Header() {
        $this->Image(__DIR__ . self::LOGO_PATH, $this->xLogo, $this->yLogo, $this->wLogo);
    }

    public function Footer() {
        $this->SetXY(34,260);
        $this->SetFont('Helvetica', 'I', 8);

        $this->SetTextColor(0, 0, 0);
        $this->MultiCell(130, 20, "footer text", 0, "C", false);
    }

}

然后我有一个基本模板，它用于所有生成的文档：

class BasePdf {

    CONST CREATOR = 'Creator';
    CONST TITLE = 'Title';
    CONST PDF_FONT_NAME_MAIN = 'Times';
    CONST PDF_FONT_SIZE_MAIN = 11;

    protected $pdf;

    public function __construct($xLogo = 8, $yLogo = 0, $wLogo = 50)
    {
        $this->pdf = new AppPdf('P', 'mm', 'A4', true, 'UTF-8', false, false, $xLogo, $yLogo, $wLogo);
        $this->pdf->SetCreator(self::CREATOR);
        $this->pdf->SetAuthor(self::CREATOR);
        $this->pdf->SetTitle(self::TITLE);

        $this->pdf->SetFont(self::PDF_FONT_NAME_MAIN, "", self::PDF_FONT_SIZE_MAIN);
    }

    public function getPdf()
    {
        return $this->pdf;
    }
}

使用基本模板，如以下类所示：

use AppBundle\Entity\HPVExam;

class HPVReport extends BasePdf
{
    public function __construct(HPVExam $HPVExam)
    {
        parent::__construct(8, 10, 75);

        $this->pdf->AddPage();
    }
}

问题是这段代码会生成pdf，顶部有一条恼人的水平线，页脚有另一条水平线，如下图所示。

我已经尝试过这里提供的建议PHP / TCPDF: Template Bug?和Changing or eliminating Header & Footer in TCPDF，但没有运气。

我做错了什么？似乎原始的页眉和页脚方法没有被正确覆盖......任何想法？谢谢！

Answer 1

只要对TCPDF说不要打印标题或去修改源....

$pdf->SetPrintHeader(false);

TCPDF类中的不需要的行与自定义页眉和页脚
