The Arcive of Official vBulletin Modifications Site.

saimon69 · #1 01-06-2011, 03:12 PM

As i said before in another thread am working in a mirgation from joomla/fireboard to vBulletin CMS, and now an working in upload the old image attachments into the vBulletin database;
to import correctly sections, I previously added two fields to the cms_node tab,called oldjoomlaid and oldjoomlasec and use it as reference here.
I already revised twice my script but am having problems in display the image in the article; instead of the image it appears the link "ATTACHMENT XXXX"; do i forget to set any parameter anywhere?

Thanks for the help.

:bump: anyone can tell me how to fix it?

Check vbulletin cms > permissions and make sure the usergroup has Can Download Attachment checked.

saimon69 · #4 01-14-2011, 05:15 PM

Am doing my test with the Admin user, i suppose that one should have the permission but will double check; however am talking about the inline images in the CMS posts; sometimes i wonder if i am uploading in the right format or need in example to base64_encode the picture and the thumbnail (not doing it now AFAICR)

I did the double check and set up download attachments for unregistered users and users awaiting confirmation/moderation; in the article same thing, in the section list view some of the articles show the thumbnail; wonder if i am doing something wrong in the way i save the images in the DB... in example do the pictures need to be base64 encoded?

Just did a test, the attachment seems not to be encoded on base64; any further ideas?

- permissions: check
- base64: check
some unknown to me flag?

Further update: it is me to insert the tag [ ATTACH= CONF1G ] num [/ATTACH ] (deliberately misspelled here) in the text; i know that but i wonder if i am using the right parameters to make the pic showing inline in the article.

--------------- Added [DATE]1295466596[/DATE] at [TIME]1295466596[/TIME] ---------------

Today's update: i checked the permissions for the usergroups and put can download attachment in all of those, to no avail; furthermore the problem is that now the imported pics thumbnails appears correctly in the list view of the section but inside the article they do not appear as such, just the ATTACH (num) link - if i edit the article i see the pic correctly in the editing field, and if i try to set position and alignment and then save, the pic is appearing correctly in the article; so at this point i wonder what is the parameter that I need to set somewhere in the DB to make the inline pictures being treated as such....

Further update: i wonder if headers have something to do with this....

Lynne · #7 01-20-2011, 03:46 AM

Something else to look for... a link is shown if there is no thumbnail image to show. Are thumbnails getting created?

saimon69 · #8 01-20-2011, 02:47 PM

@lynne
good question, this is the part that takes care of the thumbnail rendering:

PHP Code:


			

                //determine size for thumbnail
                $img2w = ($img1w >100 ) ? 100 : $img1w;
                $img2h =  round($img2w/$ratio); //rounded width/ratio

    //create the thumbnail
                $attachthumb = imagecreatetruecolor($img2w,$img2h);
                imagecopyresampled($attachthumb,$file1,0,0,0,0,$img2w,$img2h,$img1w,$img1h); 

        ob_start();        
        
                //all thumbnails are stored as png
                $thumbrendered = $vbattachthumb.$fnnoext."_thu.png";
                imagepng($attachthumb,$thumbrendered);

        ob_end_clean();

I create the thumbnails as PNG files, same thing worked for creating the avatar pics in another script; instead for thumbnails in the forum attachments I rendered them in jpeg; should i pass to jpeg instead?

BTW, i tried to generate thumbs as jpeg and same results; the problem is with the full online image; is generated too but does not appear in the post.

Lynne · #9 01-20-2011, 04:06 PM

Is there a reason you don't use the vb code to do this? Check out the function fetch_thumbnail in class_image.php and class_upload.php has the code vb uses for uploading the images. vBulletin doesn't store thumbnails as name_thu.png, they are stored as xxxx.thumb

saimon69 · #10 01-20-2011, 04:18 PM

well the main reason is that i dont understand too well vb datamanager and internals yet and have little OOP experience, so i have to go on with what i have and plus time is getting tight; will try to fix the script and see what is happening

--------------- Added [DATE]1295547599[/DATE] at [TIME]1295547599[/TIME] ---------------

btw xxxx is the thumbnail id? comes from attachment id or from filedata id? plus are those functions used also in the CMS?

--------------- Added [DATE]1295549158[/DATE] at [TIME]1295549158[/TIME] ---------------

that count because means that i have to upload the pic first and keep thumbnails data empty, then insert the thumbnail data AFTER an id for either filedataid or attachmentid is created and therefore modify my importer according to which id i have to use - or maybe i misunderstood and xxxx is the filename?
