Question

我有一个包含以下代码的PHP页面。

<?php
$filepath = '../../../user_uploads/'.$_path['uploads']
            .'prtl_icons/mod_icons_1438512347.jpg';
  require('../../../fpdf/fpdf.php');
 class PDF extends FPDF
 {
     function Footer()
    {
     // Position at 1.5 cm from bottom
        $this->SetY(-15);
      // Arial italic 8
     $this->SetFont('Arial','I',8);
    // Page number
    $this->Cell(0,10,'Page '.$this->PageNo().'/{nb}',0,0,'C');
   }
 }
$pdf = new PDF('P','mm','A4');
$pdf->Image('http://chart.googleapis.com/chart?cht=p3&chd=t:60,40&chs=250x100&chl=Hello|World',60,30,90,0,'PNG');
//$pdf->Image($filepath);
$pdf->AliasNbPages();
$pdf->AddPage();
$pdf->SetFont('Arial','B',11);
$pdf->Cell(40,10,'Family: ['.$_SESSION['UserID'].'] - '.$_SESSION['FirstName']);
$pdf->Output();
 ?>

当我运行该页面时，我收到以下错误。

Fatal error: Uncaught exception 'Exception' with message 'FPDF error: No page has been added yet' in /var/www/vhosts/portal.dev/fpdf/fpdf.php:271 
Stack trace: #0 /var/www/vhosts/portal.dev/fpdf/fpdf.php(1450): FPDF->Error('No page has bee...') #1 /var/www/vhosts/portal.dev/fpdf/fpdf.php

 thrown in /var/www/vhosts/portal.dev/fpdf/fpdf.php on line 271.

当我使用$pdf->Image($filepath)时，也会显示相同的错误。当我删除图像部分时，pdf正在正确加载。

添加图像文件时FPDF异常
