我正在尝试使用codeigniter框架中的tcpdf生成一个表。我想要生成的结构如下所示。
________________________________________________________
header 1
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
description 1 | | | | | | | |
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
header 2
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
subheader 2.1
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
description 2.1.1
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
description 2.1.2
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
subheader 2.2
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
description 2.2.1
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
header 3
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
description 3.1
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
description 3.2
虽然我能够获得上表，但生成的表不是常量。除了描述3.1和描述3.2之外，它有时会给我所有行和单元格。我尝试了mysql查询，每次都会产生预期的结果。我的代码是：
function createPDF($chklistID){
$this->load->library("Pdf");
$title="Daily Checklist Template";
$subject="Daily Checklist";
$author = "Derek Lim";
// create new PDF document
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);

$pdf->setFooterData(array(0,64,0), array(0,64,128));
// set header and footer fonts

// ---------------------------------------------------------

$chklistPath = $_SERVER['DOCUMENT_ROOT']."safety/checklists/";

}
我有什么不对的吗？
答案 0 :(得分：0)
尝试使用此代码为我工作。你必须在helpers文件夹pdf_helper.php中创建一个文件并编写这段代码，并将tcpdf库文件夹放在这个文件夹中
<?php
function tcpdf()
{
//require_once('tcpdf/config/lang/eng.php');
require_once('tcpdf/tcpdf.php');
}
?>
编写此代码
<?php get_instance()->load->helper('pdf_helper');
tcpdf();
$obj_pdf = new TCPDF('P', PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
$obj_pdf->SetCreator(PDF_CREATOR);
$title = "PDF Report";
$obj_pdf->SetTitle($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->SetPrintHeader(false);
$obj_pdf->SetPrintFooter(false);
$obj_pdf->AddPage();
ob_start();
?>
<html>write your html here .....</html>
<?php
$content = ob_get_contents();
ob_end_clean();
$obj_pdf->writeHTML($content, true, false, true, false, '');
//$obj_pdf->Output('output.pdf', 'I');
$obj_pdf->Output($this->config->item('server_absolute_path').'/application/controllers/invoice_pdf/Invoice_'.$booking_details[0]['id'].'.pdf', 'F'); ?>
名为invoice.pdf的文件将保存在控制器文件夹
中
