Upload directly to predefined album?

[ardeo]

Hi.  Is there any way that I could setup a page that would have a simplified upload process that would upload just to one predefined album?  We run photo contests, and it would be great if we could have an upload form that would just allow users to upload directly into the photo contest album.

thanks!

Well, only allow uploads to that album then.

[ardeo]

I'm afraid we wouldn't want to do that, as it would prevent people from uploading into their user albums.  What would be best would be a unique variation of upload.php that pretty much removed all the extra options and just placed the uploads directly into the contest album.  Has anyone ever tried to do that?

thanks,
roland

Haven't heard of such a mod. Can't be difficult though. You need it -> you code it.

[argie]

I would like to code this feature, I need it too. I'm reasonably proficient with php / MySQL but no expert, and don't really know the structure of Coppermine well enough to do it completely without help.

Can anyone suggest any basic pointers that might help get me started?

I currently have a working install of SMF 1.1.4, bridged successfully to CPG 1.4.16 (stable).

It would be nice to be able to write some php that I could insert into SMF's posting screen for specific boards, to allow a direct one-step upload and insert of an image to a specific gallery album.

Which sounds like broadly the same feature that the OP was looking for? 

[argie]

Got the front end done, & the raw images sat there on the server, it's just how to hook them into coppermine albums now. At which point I'm unsure which way to proceed

[argie]

proceeding apace but can anyone tell me where $CONFIG['fullpath'] is defined?

[Joachim Müller]

In include/init.inc.php. Don't edit that manually, but set it on your config screen.

[argie]

Thanks. I've been through upload.php (wow that's one big file - but really nicely documented) & have come to the conclusion it might be possible to move images into something like

Code Select Expand


$CONFIG['fullpath'] . $CONFIG['userpics'] . (USER_ID + FIRST_USER_CAT);


after some processing & checking that upload.php would normally do; then call add_picture() from picmgmt.inc.php to do the adding into the database?

But I haven't fully thought it through yet, and my hosting company put an axe through my coppermine installation last night  so I've been distracted.

Get back to it after some sleep.

[argie]

Roughed out a vague idea - I might be going about it in a really stupid manner.

Reader please comment if you see any dangers or silly stuff.

^ that's intended as a drop-in lump of code for SMF's /Sources/post.php BTW, with a hope for easy modification for other applications. Any comments as to what could be done to make that code work & work safely, appreciated - if it should be binned as a bad idea, so be it

[Nibbler]

You should be able to just make a form and post it to db_input.php?event=picture. That will take care of 99% of the work for you.

[argie]

Great.. will look into doing it that way. Two thumbs up 

[argie]

Had a look in db_input.php & it looks like it just needs supplying with the following form fields:

form enctype="multipart/form-data"
input type="file" name="userpicture"
input type="hidden" name="album"
input type="hidden" name="title"
input type="hidden" name="caption"
input type="hidden" name="keywords"
input type="hidden" name="user1"
input type="hidden" name="user2"
input type="hidden" name="user3"
input type="hidden" name="user4"

That looks like a great way of doing it, as you say, 99% of the work done.

If the OP has the freedom to do whatever they want with the form that's the way to go 

I'm trying to work within the existing SMF posting screen, so that my user can submit a picture to the gallery  within the same form submission click as the usual SMF 'post message' click. Of course that form wants to submit to SMF's processor, function post2() in it's /include/post.php file - so looks like for my interpretation of the issue I'll have to plug on and do the extra work.
