FPDF/FPDI Error: Fatal error: Class 'setasign\Fpdi\FpdfTpl' not found in
我正在尝试为现有的 PDF 文档添加水印,这个错误在过去两天一直困扰着我...
我在 fpdi/src/ 中有 FPDI 库,在 /fpdf/
中有 fpdf 库
抛出错误的文件是Fpdi.php(第27行)。这是前 30 行:

我在 PHP 方面还算可以,但这个错误真的让我陷入了困境。如果需要更多信息,请告诉我,我会提供。
如果你改变这个会发生什么:
require_once('fpdf/fpdf.php');
require_once 'fpdi/src/fpdi.php';
require_once('fpdi/src/FpdfTpl.php');
到这个?
require_once('fpdf/fpdf.php');
require_once('fpdi/src/autoload.php');
或者,如果您没有自动加载功能,那么您可能需要添加:
require_once('fpdi/src/FpdiTrait.php');
这样要求 classes:
require_once('fpdf/fpdf.php');
require_once('fpdi/src/autoload.php');
然后将 use \setasign\Fpdi\Fpdi;
添加到您的水印中而不仅仅是 use \setasign\Fpdi;
或在您的 class 声明中使用正确的 class 名称(包括完整的命名空间)。
为了它的价值,我只是将导致问题的所有功能从 "protected" 更改为 "public"。对我有用!
