PDF invoice problem after upgrade

[Stefand]

Hi everbody,

I have update my shop to prestashop 1.3.2

By the new order the PDF invoice can I open without problems.
But by the orders from the past, it says only:

Fatal error

All my previous orders in the store have the same problem, I cann't open the invoice.

The customer can also n't open it. (the same error)

Can somebody help me with this issue?

[rocky]

Temporarily change line 403 of classes/Tools.php from:

//    if ($string == 'Fatal error') d(debug_backtrace());

to:

if ($string == 'Fatal error') d(debug_backtrace());

This will display a stack trace instead of just "Fatal error". This should help you pinpoint the cause of the error.

Ok,

When I now try to open the PDF invoice in the admin I get this page:

URL : pdf.php?id_order=436&pdf;

From that stack trace, it seems the order is referencing a cart that doesn't exist. Make sure that a cart with ID 3455 exists in your ps_cart table.

[Stefand]

That was the solution for me as admin.

But the customer still cann't download the pdf invoice, they get this error:

FPDF error: Some data has already been output, can't send PDF file

[rocky]

This was supposed to be fixed in v1.3.2. That error occurs when an error message is displayed before writing the PDF file. Try manually entering the URL like pdf-invoice.php?id_order=1 and see if an error message is displayed.

[Stefand]

the same error.

[rocky]

I can't help without more information. Try adding the following before line 271 of tools/fpdf/fpdf.php from:

die('FPDF error: '.$msg);

to:

var_dump(debug_backtrace());
die('FPDF error: '.$msg);

This should provide more information about the error.

[Stefand]

see my last post.

[rocky]

No, I can't see. For security reasons, only the customer who completed the order can see the invoice. You will need to post the error message here.

[Stefand]

ok, I see this code, and then 4 pages...

It's line 1032 of tools/fpdf/fpdf.php that is causing the error:

if(ob_get_length())
   $this->Error('Some data has already been output, can\'t send PDF file');

It seems ob_get_length() is returning a length greater than 0 when it shouldn't. Unfortunately, I have no idea how to fix it.

[Stefand]

Hm. rocky thanks for the gimp, when somebody else know the solution for this problem, let me know!

[DutchCoding]

Send me your PDF.php

[Stefand]

Done, nothing wrong in the PDF.php file...
I need a solution for this problem, anyone?

[Straigh&Alert]

i have the same probleme, done what you've said and it seems :

It’s line 1032 of tools/fpdf/fpdf.php that is causing the error:

does anyone has already solved this pb ?

[Straigh&Alert]

I've found an answer working for me here :
http://www.prestashop.com/forums/viewthread/28190/

I had two white space after the closing tag in classes/product.php

[marcosaluzzo]

I have just upgraded to 1.3.2.3 I get the following message:

Fatal error: Call to undefined method Cart::getTaxesAverageUsed() in /dirpathway/shop/classes/Order.php on line 408

when viewing customer order pdfs in the front end.

I have tried Straigh&Alert;'s solution of removing the extract white spaces after the ?> in classed/Product.php but I still get this message. A quick solution to this problem is most appreciated.

Thanks, Marco

I just updated from 1.3.2 to 1.3.3 and get the error when trying to generate a PDF invoice for an old order. Other orders generate a PDF just fine. The problem is both on the backend and when the user is logged in the front end.

Here's related debug info. I kept the old 1.3.2 directory and renamed it. By renaming the old and new installs so the old 1.3.2 version is active, I am able to generate a PDF invoice.

Enabling debug in the Tools.php results in the following for the 1.3.3 version.
