Topic: Division par zero

Bonjour,

Je viens de convertir mon forum IPB, apparremment tout est OK. Sauf que les liens vers les images uploadées dans les posts sont perdus.

Lorsque je me connecte avec mon profil d'admin j'obtiens ceci :

Warning: Division by zero in c:\program files\easyphp1-7\www\punbb\upload\viewforum.php on line 119

ce qui correspond à ces lignes :

// Determine the topic offset (based on $_GET['p'])
$num_pages = ceil($num_topics / $disp_topics);

Quelle est la parade?
Merci de vote aide.

Re: Division par zero

En fait tu dois regarder dans les tables de ton forum. Il doit y en avoir une qui est composée avec que des 0, supprime-la. smile

Re: Division par zero

En fait, disp_topics est un champ de la tables 'users'. Après conversion de mon forum IPB, la valeur de ce champ est NULL pour tous les users, ce qui explique le warning "division par zero". Il suffit de saisir 20 pour voir s'afficher 20 topics par page.
Problème, si j'ai 50 topics j'obtiens 20 topics en page 1, 20 topics en page 2 et 0 topics en page 3(au lieu de 10).
Si quelqu'un a la solution...

Re: Division par zero

My French is a bit rusty, but I think I know what the problem is. Have a look at your config table. Make sure the rows 'o_disp_topics_default' and 'o_disp_posts_default' exist and that they have sane values.

Re: Division par zero

It might be the converters fault. I'll look at it.

Edit: Added some checks in the converter...

Re: Division par zero

En désespoir de cause j'ai relancé une nouvelle conversion de mon forum IPB et...tout fonctionne bien!

Rickard,
My English is a bit rusty but, during conversion IPB, is it possible to recover the images .jpg inserted in the posts?

I'm the one who made the converters. Is it the BB-code that's not working? (Or are the files uploaded to the forum somehow?)

Re: Division par zero

In forum IPB one can uploader in a post a file present on the hard disk of the user. Information relating to this file is stored in 3 fields of the table "posts":
- attach_id: example "post-2-1043353002.jpg"
- attach_type: example "image/JPEG"
- attach_file: example "fish.jpg"
During IPB->punbb conversion, this informations are not taken again. The images are thus lost.

Re: Division par zero

PunBB doesn't support attachments, so yes, they are lost.
