仅在 TCPDF 中的第一页上添加主标题

Aru*_*run 3 php codeigniter header tcpdf

我正在开发一个 pdf 页面tcpdf,用于在codeigniter. 它显示数据。但不是我需要的格式。现在它在所有页面中显示具有公共标题的数据。

我只需要在第一页上显示主标题,其余数据显示另一个子标题

我在控制器中的代码是

<?php
tcpdf();
$obj_pdf = new TCPDF('L', PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
$obj_pdf->SetCreator(PDF_CREATOR);
$title = 'Main title';
$obj_pdf->SetTitle($title);
$obj_pdf->SetHeaderData(PDF_HEADER_LOGO, PDF_HEADER_LOGO_WIDTH, $title, PDF_HEADER_STRING);

$obj_pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN));
$obj_pdf->setFooterFont(Array(PDF_FONT_NAME_DATA, '', PDF_FONT_SIZE_DATA));
$obj_pdf->SetDefaultMonospacedFont('helvetica');
$obj_pdf->SetHeaderMargin(PDF_MARGIN_HEADER);
$obj_pdf->SetFooterMargin(PDF_MARGIN_FOOTER);
$obj_pdf->SetMargins(PDF_MARGIN_LEFT, PDF_MARGIN_TOP, PDF_MARGIN_RIGHT);
$obj_pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);
$obj_pdf->SetFont('helvetica', '', 9);
$obj_pdf->setFontSubsetting(false);

$obj_pdf->AddPage();
ob_start();
// we can have any view part here like HTML, PHP etc

$tbl = <<<EOD
$pdf_cont
EOD;

$obj_pdf->writeHTML($tbl, true, false, false, false, '');

ob_end_clean();

$obj_pdf->Output('sample.pdf', 'I');

此处变量$pdf_cont包含要显示的大表。我无法检查(或者我不知道如何正确执行)我在哪个页面并设置标题数据。请帮助我在第一页上添加主标题,并在页面的其余部分添加另一个标题。

先感谢您...

您可以检查 tcpdf 的示例,并且可以继承 TCPPDF 类并使用该类:

class YOUR_CLASS extends TCPDF {
    /**
    * Overwrite Header() method.
    * @public
    */
    public function Header() {
        // if ($this->tocpage) or
        if ($this->page == 1) {
            // *** replace the following parent::Header() with your code for TOC/page you want page
            // parent::Header();
            // this will add logo and text to first page
            $this->Image('http://localhost/first_page_logo.png', 10, 10, 15, '', 'PNG', '', 'T', false, 300, '', false, false, 0, false, false, false);
            $this->SetFont('helvetica', 'B', 14);
            $this->Cell(0, 15, 'First page header text', 0, false, 'C', 0, '', 0, false, 'M', 'M');
        } else {
            // *** replace the following parent::Header() with your code for other pages
            //parent::Header();
            // following will add your own logo ant text to other pages
            $this->Image('http://localhost/other_pages_logo.png', 10, 10, 15, '', 'PNG', '', 'T', false, 300, '', false, false, 0, false, false, false);
            $this->SetFont('helvetica', 'B', 14);
            $this->Cell(0, 15, 'Other pages header text', 0, false, 'C', 0, '', 0, false, 'M', 'M');
        }
    }
} // end of class
