嘗試使用FPD和TCPDF使用Symfony2

Question

我想在symfony2中使用TCPDF的FPDI。

我可以單獨使用TCPDF，沒有任何問題。但是當我嘗試使用FPDI時，我收到錯誤。

在我composer.json我把以下內容：

"autoload": { 
     "psr-0": { "": "src/" 
     }, 
     "classmap": ["vendor/tcpdf/tcpdf.php","vendor/fpdi/fpdi.php"]  
    }, 

然後控制器可以實例化一個TCPDF類

$tcpdf = new \TCPDF(); 

但是當我嘗試實例化一個FPDI實例

$fpdi = new \FPDI(); 

當我嘗試訪問路由時，Symfony會引發以下錯誤。

* FatalErrorException：錯誤：類 '的Symfony \元器件\調試\異常\ ContextErrorException' 用C未找到：\ XAMPP \ htdocs中\ CONSULTA \廠商\ FPDI \ fpdi2tcpdf_bridge.php線169 在C：\ XAMPP \ htdocs中\ Consulta \ vendor \ fpdi \ fpdi2tcpdf_bridge.php line 169 *

有誰知道如何解決這個問題？

我加入fpdi2tcpdf_bridge.php

Answer 1

的內容添加packagist參考composer.json正常方式：

https://packagist.org/packages/setasign/fpdi

"setasign/fpdi": "1.4.2"

這似乎是別名https://github.com/mark9000/FPDI.git

這應該自動加載它正確。
