我对 TCPDF 有疑问：
查看PDF：
function viewPdf($id = null)
{
if (!$id)
{
$this->Session->setFlash('Sorry, there was no property ID submitted.');
$this->redirect(array('action'=>'index'), null, true);
}
Configure::write('debug',0); // Otherwise we cannot use this method while developing
$id = intval($id);
$property = $this->__view($id); // here the data is pulled from the database and set for the view
if (empty($property))
{
$this->Session->setFlash('Sorry, there is no property with the submitted ID.');
$this->redirect(array('action'=>'index'), null, true);
}
$this->layout = 'pdf'; //this will use the pdf.ctp layout
$this->render();
}
__看法：
function __view($id = null) {
if (!$id) {
$this->Session->setFlash(__('Invalid Calculation.', true));
$this->redirect(array('action'=>'index'));
}
$this->set('calculation', $this->Calculation->read(null, $id));
}
查看PDF.ctp：
<?php
App::import('Vendor','xtcpdf');
$tcpdf = new XTCPDF();
$textfont = 'freesans'; // looks better, finer, and more condensed
than 'dejavusans'
$tcpdf->SetAuthor("KBS Homes & Properties a http://kbs-properties.com");
$tcpdf->SetAutoPageBreak( false );
$tcpdf->setHeaderFont(array($textfont,'',20));
$tcpdf->xheadercolor = array(150,0,0);
$tcpdf->xheadertext = 'Test';
$tcpdf->xfootertext = 'Copyright © %d KBS Homes & Properties. All
rights reserved.';
// Now you position and print your page content
// example:
$tcpdf->SetTextColor(0, 0, 0);
$tcpdf->SetFont($textfont,'B',20);
$tcpdf->Cell(0,14, "Hello World", 0,1,'L');
// ...
// etc.
// see the TCPDF examples
$tcpdf->Output('filename.pdf', 'I');
?>
CakePHP 2.2 的 PDF 布局（已弃用 $content_for_layout）：
<?php
header("Content-type: application/pdf");
echo $this->fetch('content');
?>
应用程序/供应商中的 xtcpdf.php：
<?php
App::import('Vendor','tcpdf/tcpdf');
class XTCPDF extends TCPDF
{
var $xheadertext = 'PDF created using CakePHP and TCPDF';
var $xheadercolor = array(0,0,200);
var $xfootertext = 'Copyright © %d XXXXXXXXXXX. All rights reserved.';
var $xfooterfont = PDF_FONT_NAME_MAIN ;
var $xfooterfontsize = 8 ;
/**
* Overwrites the default header
* set the text in the view using
* $fpdf->xheadertext = 'YOUR ORGANIZATION';
* set the fill color in the view using
* $fpdf->xheadercolor = array(0,0,100); (r, g, b)
* set the font in the view using
* $fpdf->setHeaderFont(array('YourFont','',fontsize));
*/
function Header()
{
list($r, $b, $g) = $this->xheadercolor;
$this->setY(10); // shouldn't be needed due to page margin, but helas, otherwise it's at the page top
$this->SetFillColor($r, $b, $g);
$this->SetTextColor(0 , 0, 0);
$this->Cell(0,20, '', 0,1,'C', 1);
$this->Text(15,26,$this->xheadertext );
}
/**
* Overwrites the default footer
* set the text in the view using
* $fpdf->xfootertext = 'Copyright © %d YOUR ORGANIZATION. All rights reserved.';
*/
function Footer()
{
$year = date('Y');
$footertext = sprintf($this->xfootertext, $year);
$this->SetY(-20);
$this->SetTextColor(0, 0, 0);
$this->SetFont($this->xfooterfont,'',$this->xfooterfontsize);
$this->Cell(0,8, $footertext,'T',1,'C');
}
}
?>
而且我总是收到“抱歉，提交的 ID 没有属性”。我没有看到问题。
