For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Uploading a document or image to its own URL via a browser

One of the major requirements of a committee / working group such as the TransWilts Community Rail Partnership is to be able to share information - and a forum (such as Simple Machines) does that admirably. So after yesterday's meeting, I put up a forum for our initial work.

But one of the side issues / extra elements is to be able to upload and share pictures, documents and much more ... and that's where something a bit more is needed.

"How do you upload a picture to the site", "How do I share a document" is often asked; you could use sites such as flickr, but perhaps it's better to upload to your own site and keep everything in one place.

I've previously tested an upload page - [source] showing the upload mechanism, but now I've added a thin veneer on top of it to allow the uploaded files to be given their own URL, listed, replaced, etc. - and that new complete example with the veneer is [source here].

Security is a major issue with scripts such as this - avoiding data being injected by third parties who aren't part of the group and who have other purposes; we are using the security of the SMF login accounts we already have on the server - so that uploads will only work for logged in members and not for guests.
