This seems to work!

|t1 t2 |
t1_ WeakKeyAssociation new value: #('This is a test.').
t1 key: 'test'.
t2 _ #() asOrderedCollection.
t2 add: t1.
^ HTTPSocket httpPostDocument: 'www.blocks.scratchr.org/postPing.php' args: t2

This code assigns the string "This is a test." to the arg "test" and appears to successfully pass the data.

Thank you SO much Greenatic. You are amazing. I modified the code a little for 4 arguments and it works. Now sparks and I can start making the upload feature, right sparks?

No problem. 

I specifically made t2 an OrderedCollection so that you could add as many args as you needed.  If you're going to pass the same number of args each time, using a simple Array should work as well.

Yeah, I understood that. I'm mentioning this in the credits.
"Credit to Greenatic for making uploading blocks possible and beta testing."

Hey guys! I've been ill most of this week and am still pretty under the weather and I have a programming exam on Thursday but I'll do my best to add the upload feature for this!

Since we'll be storing block files on the site as SQL database entries, I'm really worried the whole SQL system is going to cause problems. I think that dreamod, your code should allow for error messages to be sent back from the site should a problem occur so you can display a message to the user. Here are some I can think of:

wrongUsernameOrPass
blockAlreadyExists
SQLConnectionError

For the last one, I suggest entering a loop that tries four or five more times, and if it fails then, display a message along the lines of "The block could not be uploaded to the library right now. Please try again later."

I'll have a stab at the upload code now 

@Greenatic: yes, the error names I suggested would be worked out by my code and echoed back to the smalltalk    The code is nearly done. Oddly enough, the thing that took the longest was parsing spec, type and category from the block file 

Then again, I'm not getting an SQL error every time I try the button on the home page of the library site so maybe there's a problem with that code. I'll take a look tomorrow. It's 10:50 here and I'm ill

Get well soon. I'll fix that. how about if there is an error on uploading the block, the webpage displays: 'error: message informing what went wrong'. That way the block importer would read the 'error:' line and then display a dialog with the title error and the message after 'error: '.

@Dreamod: Okay, cool. I'll create more informative errors then 

Although really, things like missingArgs are things that YOUR code should respond to (or never get by checking all variables are set to something)... you do have to send a comment, even if the comment is blank.

Another thing, what if say, a librarian or you are uploading a load of blocks from the library to the site? It's not really fair that we then get credited for the creation of that block, which is why my table has a "creator" and a "sharer" field. It might be nice if your upload process could give the option for a user to credit another with the block's creation.

@Greenatic:
"block files" will actually be entries to a database, so yes, a manual viewer and editor could be built. When someone wants to download a block file, the file will be created using the database information as and when it is needed, then deleted when the download is complete. I'll add the remoteBlockUploader.php to the Librarian editor list, and get the image uploader up again, although remember we're not uploading images of blocks now.

I'll add a credit field. But concerning the current blocks I think we should upload them using a 'false ID'. Basically skip the password field until all the blocks are up. I'm not sure how we can do that safely, though.

Hmm, yeah, that or we upload them with the creator's name in the comments. A Librarian will later be able to edit the creator field properly using some editor I'll build.

ok. By the way, about the comment field. If it is left blank then it is treated as an empty string basically "". but it's still a field and included. I'm going to see if I can make block files of the library again. All I have to do is import them and upload them when that works.

sparks wrote:

Okay. I think I'll take away the comment field from the missingArgs message.

Still no idea why I always get the SQLConnectionError message 

Keep it, you never know if someone will hack the block importer and remove a field.

sparks wrote:

Well in that case you should make sure that the comment field contains a space or something if it's empty. (That sentence makes little sense, I mean send a space instead of nothing to the uploader.)

Well, the comment field is automatically initialized to an empty string, and no space is required, because it's still a string object even if it's empty. (does that make any sense?) But if there are fields that have been hacked away then that's when the error would act.
Any ideas for the block uploading?

Should I change the upload url to 'http://blocks.scratchr.org/remoteBlockUploader.php'?
