Sample stack and lc server scripts for uploads to lc server

Post by matthiasr » Mon Jun 12, 2017 12:01 am

Hi,

i´ve created a little stack and two livecode server scripts that allow to upload a file to a web server running livecode server version 8 or higher.
After successful upload the download url of the uploaded file is copied to the clipboard for sharing purposes. The stack has a little filemanager included which allows to get the d/l url for older uploaded files and it allows also to delete older files which are not needed anymore

The stack uses Bernd Niggeman´s Gauge widget for showing the upload progress. See his post about this really cool widget http://forums.livecode.com/viewtopic.ph ... ge#p154776

There are only minimal adjustments needed in the stack script of the livecode stack to get it running with your web server.

The archive contains the livecode stack, 2 livecode server scripts, the .lcb file for the Gauge widget, an installation guide for the Widget and a readme file.

I´ve tested it with Livecode 8.1.4 and Livecode server 8.1.2.

Please read the file PLEASE Read Me First!.txt first.

Hope it´s of some use for the one or the other


Unfortunately the zip archive is 452kb in size and the forum does only allow attachments with a size up to 256kb.
Therefore please find the archive here http://dl.qck.nu/?dl=DropUpload.zip

As the stack only runs with LC 8.1.4, because of the widget, i decided to make some changes to the stack, so it can be used either with the widget (LC 8.1.4) or with a scrollbar (any LC8 or 9).

If you want to use the stack with a scrollbar instead of the widget, then just delete the gauge widget on the card "main" and run the following command in the message bo

dispatch "setupProgressObject" to stack "DropUpload" This makes the scrollbar and a background image visible.

If you later decide to use the widget instead of the scrollbar, just add the gauge widget to the stack (don´t care about position or size) , make sure its name is "gauge" and run the above command again.
This then hides the scrollbar and the background image and moves the widget into its correct position and makes also some changes to the widget (size and display options).

The link is still the same:

Hello,

This is a really great example; thanks for sharing. I am only just beginning to experiment with the tsNet capabilities myself. By the way... Is there a way to cancel uploads while in progress? I see "tsNetClose" and "tsNetCloseConn" in the dictionary, but I'm not having much success playing with them.

Thanks!

Hi Again,

Okay; you can use tsNetPost to upload asynchronously and cancel the upload with tsNetCloseConn and a custom connection ID.

In Matthias' code, you can use:

Code: Select all

get tsNetPost(pConnectionID, tURL, pHeaders, line 2 to -1 of sFormData, pCallback, pSettings)
I also got it working with a progress bar utilizing a send handler to update the progress accordingly...

Cool stuff. (And still playing around with it.)

Cheers,
