FPDF library "Output" doesn't work?

My problem with [FPDF] library is the next:

$pdf->Output("doc1.pdf","D");

In the above example I replaced the D with I or S or F the result is always the same: a popup appears to save or open the file.

I want to save it without a开发者_开发百科 popup into a specific directory.

Have you added an header which tells the browser the output is an pdf file? Try:

header('Content-type: application/pdf');

Just before the output.

---

maybe use this

$pdf->Output('D:/example2.pdf','F');

F = save to a local file with the name given by name D:/example2.pdf = dest folder and name of file ,,,,

thats it, save it without a windows popup appears

---

if you read the documentation at http://www.fpdf.org/es/doc/output.htm says that dest should be first and the name second, although all of them are optional.

$pdf->Output("D","example2");

you shouldnt name your file .pdf because it will add it when you download it

Make sure you didn't output absolutely nothing before calling the Output (neither a whitespace, tab or anything) or the browser will just go nuts. Pay special attention at your includes, if any.
