Fpdf - return to previous page

Question

I am creating a pdf account using fpdf.

Some invoices containing many items and details need to go to the second page. However, I need general and other details that will be displayed on the first page.

Right now, if I can add a new page as follows: $ Pdf-> AddPage ();

But this puts everything on the second page, regardless of this statement.

There seems to be no way to specify a page for recording methods or cells.

Rendering, and bit calculations are complicated, so you do not need to store temp in the array and display after the full rendering of the first page.

Thanks.

Answer 1

if(!empty($this->replace) && !empty($this->replacement)){
    $this->pages[$n]=str_replace($this->replace,$this->replacement,$this->pages[$n]);
}

fpdf _putpages() / 2851

:

$pdf->replace = array("{paid_msg}","{balance}");
$pdf->replacement = array("Paid","0.00");
