For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.
Viewing images held in a MySQL database via PHP

LOTS of questions on this at the moment. We have a couple of sample scripts that do it - have a look at:

* feeder.php which adds images into a database if they've been uploaded as plain text files, displays them from the database if that's where they are already, and generates a rather more informative than usual graphic if you call up a picture that does not exist.

* pic_alog.php which selects images by title from a database. There's a page here which explains this a bit more, and points you at the upload script too.
