header contain a variable

[dll-live]

Hi together

I found this library, and it's pretty cool to work with.
My python knowledge level is beginner . so i have a question which is for the geek easy.
what i have to do, that i can use a variable in the header section?
i work successfull the tutorial section 2 - there the header is static - now i want it dynamic (with one variable - e.g.: Date or a invoicenumber.

please help me, it would be great if you put a code sniplet.

Already many thanks.

best regards

It's as simple as using your variable on the text parameter of cell().

Here's an example:

from datetime import datetime
from fpdf import FPDF

class PDF(FPDF):
    def header(self):
        self.set_font("helvetica", style="B", size=15)
        # print the date on the left
        self.set_xy(self.l_margin, 5)
        self.cell(w=self.epw, text=datetime.today().strftime('%Y-%m-%d'), align="L")
        # print the invoice number on the right
        self.set_xy(self.l_margin, 5)
        self.cell(w=self.epw, text=self.invoice, align="R")
        # draw a line under the header
        self.line(self.l_margin, 12, self.w - self.r_margin, 12)
        self.set_xy(self.l_margin, self.t_margin)
        


pdf = PDF()
pdf.set_margins(15, 20)
pdf.invoice = "Invoice n. 123"
pdf.add_page()
pdf.set_font("helvetica", size=14)     
pdf.cell(text="Testing")
pdf.output("mytest.pdf")
