更改TCPDF标题字符串浮动
问题描述:
你好*人,我需要TCPDF的帮助,我不知道如何使标题字符串浮动正确。贝娄有我的剧本的代码。我想离开标题标识,但标题字符串是问题。那么我怎么能改变它的权利?更改TCPDF标题字符串浮动
$pdf->SetHeaderData(PDF_HEADER_LOGO, PDF_HEADER_LOGO_WIDTH, $AppUI->_('Project Completed Task Report'), PDF_HEADER_STRING);
答
要创建custome头部,则需要扩展TCPDF类并覆盖Header()
功能: 然后在功能有一个Cell()
方法,你需要修改其属性之一:
假设
$this->Cell(0, 15, '<< Header TITLE >>', 0, false, 'C', 0, '', 0, false, 'M', 'M');
的'C'
表示CENTER(默认),您需要更改为'R'
才达到浮动权
$this->Cell(0, 15, '<< Header TITLE >>', 0, false, 'R', 0, '', 0, false, 'M', 'M');
这是我简化了例子:(根据您的TCPDF文件夹所属的位置改变require_once()
值)
<?php
require_once('D:\tcpdf\tcpdf.php');
// Extend the TCPDF class to create custom Header and Footer
class MYPDF 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 to right allignment
$this->Cell(0, 15, '<< Header TITLE >>', 0, false, 'R', 0, '', 0, false, 'M', 'M');
}
}
// create new PDF document
$pdf = new MYPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
// set document information
$pdf->SetCreator(PDF_CREATOR);
$pdf->SetAuthor('Nicola Asuni');
$pdf->SetTitle('TCPDF Example 003');
$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, PDF_HEADER_STRING);
// 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 font
$pdf->SetFont('times', 'BI', 12);
// add a page
$pdf->AddPage();
// set some text to print
$txt = <<<EOD
Custom page header and footer are defined by extending the TCPDF class and overriding the Header() and Footer() methods.
EOD;
// print a block of text using Write()
$pdf->Write(0, $txt, '', 0, 'C', true, 0, false, false, 0);
$pdf->Output('example.pdf', 'I');
