For 2023 - 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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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))
.css - using PHP to make dynamic style sheets
Did you know that you can use PHP to generate dynamic style sheets? If you look at the accessibility options on our new-look website, you'll find you can change the colour and font size on all the pages, and you can select wide and narrow too. And if you're using an older browser that doesn't fully support styles you'll get an older-look menu than if you have IE6 or similar.
A lot of hard work? Oh yes, but all in one set of pages. Our style sheets are not simply flat files - but rather they're php files that generate the necessary style combination from a single master file, with parameters passed in to set all the various parameters. Here, for example, is the start of the file and part that sets one of the font sizes.
$mencolour = "#ffffcc";
$texcolour = "#000000";
$bfsize = 10;
if ($_REQUEST[fsize] == 4) $bfsize = 8;
if ($_REQUEST[fsize] == 2) $bfsize = 12;
if ($_REQUEST[fsize] == 1) $bfsize = 16;
font-family: Verdana, Arial, Helvetica, sans-serif;
font-size: <?= $bfsize ?>px;
Other issues that will arise if you use this "trick" are cache controls - making sure that the style sheet isn't sent our for every page - and ensuring that the file is parted by the PHP handler even if you choose to give it a .css extension. (written 2005-11-21, updated 2006-06-09)
