Can't search for "pdf" post in the forum...

[lcollong]

Hi,

I'm getting a blank page while clicking on the pdf button on a list view. No errors generated (firebug). I'm sure this has already been addressed in the forum but due to the "more than 3 letters" search limitation, I can't search the forum for the word "pdf"... may be it would be possible to set up some "white list" of useful small words to search for ?

BTW, any hint about the reason of pdf construction not being triggered ?

You can use google for searching
site:fabrikar.com/forums pdf

Is the blank page showing immediatly or after e.g. 30 sec (php timeout)?
Did you set error reporting to max?

Dompdf has several limitations with divs or tables spanning more than one page.
The dompdf lib included in Fabrik3.0 Github is old, you may take the one from Fabrik3.1 or from dompdf Github.

Hi Troester,

Thanks for the Google tip. I should have think about this solution...

The white pdf doc is showing after some seconds. Sounds normal time. No evidence of any php timeout. I'm doing tests on very simple, few columns, few lines list. I'll check with error reporting to max and will see if I can change something including another lib.

Thanks for your help

PHP Fatal error: Call to undefined function imagecreatefrompng()

hmm seems your server is missing a full GD (http://us3.php.net/imagecreatefrompng) install, ask your hosts if they can install it.

Hi Rob,

Indeed, you were right. But now, I have this in the error.log:
[Mon Nov 18 17:22:46 2013] [error] [client xx.xx.xx.xx] PHP Warning: Illegal string offset 'hex' in /var/www/test/libraries/dompdf/include/style.cls.php on line 1544, referer: http://test.test.info/index.php?opt...id=15&calculations=0&resetfilters=0&Itemid=27

producing the following error on the front :
Firefox ne peut trouver le fichier ? l'adresse http://test.test.info/index.php?opt...format=pdf&listid=15&resetfilters=0&Itemid=27.

HI Jerome
what's the actual site url?
For the notices, it must be something in the markup that dompdf isn't liking.

Hi Rob,

I'm able to reproduce the problem on the "basulm_clone" test site in "mySites". You have to connect on the front using the second login (publisher).
1- If you go to "Gestion" >> "Type d'acc?s" it displays a small table on which the pdf generate function IS running.
2- if you go to "Gestion" >> "Type de plate-forme (cod?)" it displays a bigger table on which pdf IS generated but with an error on the last column (double '/' near the image name).
3- if you go to "Cr?ation/tableau de bord" >> "Tableau de bord", the pdf is triggered but shows a blank page.

Here is an extract of the corresponding error.log :

I've got some way with this - we need to define the dom pdf tmp folder when the server is running in safe mode.
That produces a pdf for 'Type de plate-forme (cod?)' with some of the images showing (not sure what the difference is between those that show and those that dont are though.

Tableau de bord however still gives a blank pdf, any chance you can look again in your logs to see if there are any errors related to this page?

Hi Rob,

Thanks, here in an extract of the error.log which seems to correspond to the period you drive some tests. I've replaced myIP and what I think is yours. I've also trace of hacks tries.....
