New , Improved Blog

I have moved the DSA blog to the new Beta-Blogger. This provides for tagging of blog entries and an improved user interface which I hope will assist you all.

The announcements on UWEOnline are based on a feed from this blog. The order is oddly different from the entries in the blog itself due to the order in which entries where actually created. Publish

Week 7 - Browser- Server interaction with PHP

The slides for this lecture describe how to use forms and sticky forms with PHP. Here are the full set of examples. Note that in this code, the parameters are referenced directly as PHP variables, rather than using the $_REQUEST array in the album code. This approach is usable but depreciated ( i.e. you are advised not to use it). Most (All?) commercial hosting sites will require the more wordy but more secure approach.


I have also adapted a tutorial from the WebMonkey site and added some advice on how to use PHP at home, paying special attention to how to secure your server which is very important.
