如何在tpl文件中调用tcpdf非静态方法
How to call tcpdf non-static method in tpl file
我在 Prestashop 1.7 的送货单模板中生成条形码时遇到问题。6.x（或仅 1.7）使用我在 Prestashop 1.6 中使用的相同模板
当我通过
它给我错误使用“$this when not in object context”
这是通过 Symfony 调试器的堆栈跟踪
Symfony\Component\Debug\Exception\FatalThrowableError:

1.PS : 当我排除条形码时一切正常
2.PS2：相同的代码仍在 Prestashop 1.6 上运行，没有问题
3.PS3：我设置定义（'K_TCPDF_CALLS_IN_HTML'，真）； // 为假，所以我可以在 tpl 文件中调用 tcpdf。
4.PS4 : tcpdf 的配置文件位于 vendor\tecnickcom\tcpdf\config\tcpdf_config.php
如有任何帮助，我们将不胜感激。
我对 smarty 不熟悉，所以以下只是一个猜测，但它可能有效...
您的文件 override\classes\pdf\PDF.php 向 smarty 添加了内容。我不太确定，如果 smarty 的版本匹配（你可能需要检查）但是 you theoretically can assign values:
$this->smarty->assign('tcpdf', $this->pdf_renderer);
假设您的 PDFGenerator ($this->pdf_renderer) 实际上扩展了 TCPDF。
如果可行，您应该能够做到：
{assign var=params value=$tcpdf->serializeTCPDFtagParameters($order->shipping_number,...)}
希望这有效 ;o)
