问题
I've taken a dive into FPDF lately and something that i don't seem to understand is - why is there no way to set a bottom margin? There are functions for setting margins from the top, left and right, but not from the bottom.
I assume now that i misunderstand something basic and conceptual about how FPDF works yet i got no clue on what that could possibly be.
So to cut it down:
Is it possible to define a fixed bottom margin in FPDF?
回答1:
I just found the solution - the bottom margin is simply left out of predefinition because it is part of the page break calculation process. Therefore, setting a bottom margin in itself is not possible, but it can be done using
SetAutoPageBreak(boolean auto, [float margin])
回答2:
+1 to SquareCat's answer. To expand on this a little more, if you're having trouble with text going a little bit over the auto page break, just setting SetAutoPageBreak(false) will probably be sufficient to solve the problem. For me personally this was causing trouble when creating mailing labels.
$fpdf->SetAutoPageBreak(false);
Just make sure that you're manually breaking pages where appropriate for your PDF.
$fpdf->AddPage();
