在 codeigniter 中如何获取 tcpdf 自定义页眉和页脚

Question

我生成pdf的控制器如下

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class C_test extends CI_Controller {

    function __construct()
    {
        parent::__construct();
        $this->load->library("Pdf");    
    }
    public function create_pdf() {
    $pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);    
    $pdf->SetCreator(PDF_CREATOR);
    $pdf->SetAuthor('Vijay Kumar');
    $pdf->SetTitle('TCPDF Example 001');
    $pdf->SetSubject('TCPDF Tutorial');
    $pdf->SetKeywords('TCPDF, PDF, example, test, guide');   
     set default header data
   $pdf->SetHeaderData(PDF_HEADER_LOGO, PDF_HEADER_LOGO_WIDTH, PDF_HEADER_TITLE.' 001', PDF_HEADER_STRING, array(0,64,255), array(0,64,128));

    $pdf->setFooterData(array(0,64,0), array(0,64,128)); 

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

    // set auto page breaks
    $pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM); 

    // 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 default font subsetting mode
    $pdf->setFontSubsetting(true);   
    $pdf->SetFont('dejavusans', '', 14, '', true);   
    $pdf->AddPage(); 

    // set text shadow effect
    $pdf->setTextShadow(array('enabled'=>true, 'depth_w'=>0.2, 'depth_h'=>0.2, 'color'=>array(196,196,196), 'opacity'=>1, 'blend_mode'=>'Normal'));    

    // Set some content to print
    $html = <<<EOD
    <h1>Welcome to  pdf gen</h1>
EOD;

    // Print text using writeHTMLCell()
    $pdf->writeHTMLCell(0, 0, '', '', $html, 0, 1, 0, true, '', true);  
    $pdf->Output('example_001.pdf', 'I');    

    }
}

pdf.php图书馆

<?php 
if ( ! defined('BASEPATH')) exit('No direct script access allowed');

require_once dirname(__FILE__) . '/tcpdf/tcpdf.php';

class Pdf extends TCPDF
{
 function __construct()
 {
 parent::__construct();
 }
}

我想生成一个带有自定义页眉和页脚的 pdf，页眉是图片，页脚是动态名称，需要页码

在控制器中如何执行此操作以使用自定义 pdf 页眉和页脚

Answer 1

您需要扩展 TCPDF 才能使用自定义页眉和页脚

class PDF extends TCPDF {

    //Page header
    public function Header() {
        // Logo
        $image_file = K_PATH_IMAGES.'logo_example.jpg';
        $this->Image($image_file, 10, 10, 15, '', 'JPG', '', 'T', false, 300, '', false, false, 0, false, false, false);
        // Set font
        $this->SetFont('helvetica', 'B', 20);
        // Title
        $this->Cell(0, 15, '<< TCPDF Example 003 >>', 0, false, 'C', 0, '', 0, false, 'M', 'M');
    }

    // Page footer
    public function Footer() {
        // Position at 15 mm from bottom
        $this->SetY(-15);
        // Set font
        $this->SetFont('helvetica', 'I', 8);
        // Page number
        $this->Cell(0, 10, 'Page '.$this->getAliasNumPage().'/'.$this->getAliasNbPages(), 0, false, 'C', 0, '', 0, false, 'T', 'M');
    }
}

甚至我也这样做并得到了我的结果。
