TCPDF在本地工作，但不在线

Question

我正在使用PHP*TCPDF/FPDI类动态生成PDF。。

虽然本地发展（WAMP/localhost）...

现在我已经把东西上传到了直播服务器上。。我在同一个文件上只得到一张空白页。。使用相同的目录结构。。

但是，在实时环境中进行测试时。。它不起作用？

只是一个空白页，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超文本标记语言输出中添加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';

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

//error_reporting(E_ALL | E_STRICT);

require('/path/to/tcpdf.php');  
require('/path/to/fpdi.php');  //make sure to include the _TPL file in directory or it throws error.

}else{

只是一个空白/空的白色页面每次测试活...

我错过了什么或做错了什么？

Answer 1

放置TCPDF输出文件时，请确保从服务器的根目录开始。要这样做，请获取信息。在输出文件所在的位置运行php。打开信息。然后向下滚动，它会显示php文件的完整路径。将路径用作输出位置。。。

我的tcpdf上有这个问题，它解决了这个问题。

Answer 2

固定的：

有几件事需要记住：

1.）在开始输出之前，不要有任何空白或空格

2.）确保您的FPDI目录中有文件：fpdf_tpl.php。.

（第二个似乎是我一开始的失败）：）

Answer 3

我也有这个问题。为我修正的是添加

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

略高于$pdf-
