Question

我正在使用PHP * TCPDF / FPDI类动态生成PDF ..

在本地开发（WAMP / localhost）时......事情一直很好......

现在我已经将内容上传到LIVE服务器..我只得到SAME文件上的空白页面......带有SAME目录结构..

但是，在LIVE环境中进行测试时......它不起作用？

只是一个空白页面，没有错误..等等。

这是我目前使用的代码..

（我试图在构造函数和HTML输出中添加UTF-8编码...... ??

代码：

$live = false;

$targetID = 122;
$targetName = "Name";
$targetClient = "Client Name";

$targetAddress = "address";
$targetCity = "city";
$targetState = "State";
$targetZip = "40202";
$targetPhone = "xxx-555-1212";

$fileCreator = "xxxxx123";  
$fileAuthor = "xxx";
$fileTitle = "Title";
$fileSubject = "Ssubject";

if($live){
$targetLogo = "/path/to/logo/images/targetLogo.jpg";
$sourcePDF = "/path/to/pdf/targetPDF.pdf";
}else{
$targetLogo = "images/targetLogo.jpg";
$sourcePDF = "targetPDF.pdf";
}
$saveAsName = "DYNAMIC_BRANDING.pdf";

//client specific variables
$clientName_color = '#FF0000';
$memberName_color = '#000000';
$clientAddress_color = '#000000';


//------------------[end project vars]---------------------//



// just require TCPDF instead of FPDF
define('FPDF_FONTPATH', 'tcpdf/fonts/');
//include FPDI & TCPDF class library file(s)


if($live){
//ini_set('display_errors', '0');
//error_reporting(E_ALL | E_STRICT);
//live
require('/path/to/tcpdf.php');  
require('/path/to/fpdi.php');  //make sure to include the _TPL file in directory or it throws error.

}else{
ini_set('display_errors', '0');
error_reporting(E_ALL | E_STRICT);
//local file path (WAMP server)

$pdf->SetAuthor($fileAuthor);
$pdf->SetTitle($fileTitle);

//add 'footer/branding' data at bottom

//output
$pdf->Output($saveAsName, 'I');

每次实时测试时只是一个空白/空白页面。

我错过了什么或做错了什么？

Answer 1

固定：

要记住几件事：

1。）在你开始你的OUPUT之前没有任何空格或空格

2。）确保你的FPDI目录中有文件：fpdf_tpl.php ..

（第二个似乎是我最初的垮台）：）

Answer 2

放置TCPDF输出文件时，请确保从服务器的根目录开始。为此，请在输出文件所在的位置运行info.php。打开info.php并几乎一直向下滚动，它将显示您的php文件的完整路径。使用路径有输出位置...

我有这个问题，在我的tcpdf上它解决了问题。

Answer 3

我也有这个问题。对我来说固定的是添加

while( ob_get_level() ) {
    ob_end_clean();
}

正好位于$pdf->Output上方。可能与在Bluehost上的WordPress上使用TCPDF有关。

TCPDF在本地工作，但不在线
