将fpdf输出存储在服务器中并在数据库中添加文件名

Question

我正在使用fpdf库生成发票，该库从数据库中获取数据，现在生成pdf时，我想将文件保存在文件夹中，并在数据库中添加带有日期的文件名，以便我可以提取以前在表中生成的所有发票请在这里帮助我。

Answer 1

Be shure that you can write to the directory.

$filename="/Mydirectory/bill01.pdf";

Save the Pdf.

$pdf->Output($filename,'F');

Update the Sql Tables

$query=" UPDATE `shopdb`.`bills` SET `bill_doc_crea` = '1', `bill_pdf_doc` = '".$filename."' WHERE `bills`.`ordernummer` ='".$orderId."' ;";

Answer 2

Output([string dest [, string name [, boolean isUTF8]]])

Destination where to send the document. It can be one of the following:

I: send the file inline to the browser. The PDF viewer is used if available.
D: send to the browser and force a file download with the name given by name.
F: save to a local file with the name given by name (may include a path).
S: return the document as a string.

Normally the Parameter F should only save to disk.
It looks that fpdf are forcing download. In this case use of tcpdf https://tcpdf.org/ should be useful. I use it and it works fine. Save to disk and insert in DB
