如何在 Codeigniter 中更改从 TCPDF Library 生成的 PDF 文件的 header？

Question

我正在使用 TCPDF 库生成 PDF 发票，但问题是 header 不应该是静态标题/徽标，我知道我可以从 tcpdf_config.php 更改它从这一行

define ('PDF_HEADER_TITLE', 'TCPDF Example');

/**
 * Header description string.
 */
define ('PDF_HEADER_STRING', "developerd by syam");

但我想从数据库中检索标题和 header。这是我的 PDF 视图：

如何从数据库中检索 header？

Answer 1

如果您从使用常量值更改为从数据库中检索数据，您应该能够设置所需的 header 详细信息，即将常量 PDF_HEADER_TITLE 更改为来自数据库的标题，即 $invoice->title

换行

$pdf->SetHeaderData(PDF_HEADER_LOGO, PDF_HEADER_LOGO_WIDTH, $invoice->title , PDF_HEADER_STRING);

最好还有：

$pdf->SetTitle($invoice->title);
