How can i make a drop down list, which when an option is selected, a small piece of PHP code will change.
For example, i have a number of different categories, in a news system (Cute News, most of you will probably know about it). To display the news from a certain category, you enter a small line of code into the PHP insert news code, which specifies the category. I want the visitor to be able to select a category from the drop down list, and for in a table below that, the news from that category to show.

So, all I really need is to be able to specify what code is to be displayed in the table for each value in the drop down list.

Hope this makes sense

Does anyone have any ideas, or code which does this?

Thanks.

You can't really do this in PHP, but you can in Javascript with this wonderful little bit of code from Matt Kruse:

I beg to differ. This can be done with php/pear or via using php/JavaScript (JSRS) without the need for a full browser recall.

What would be the simplest way to have a drop down menu which when an option is selected changes the value of a variable... I've seen many ways of doing this in a number of different languages, but do any of you know (preferably) php based way of doing this?

[Code examples please, I'm a big n00b ; ) ]

By far the simplest solution would be DHTML (JavaScript). Tyr googling for chained selectors, dhtml dropdowns, dynamic dependant list menus etc and you should find a whole load of results. My advice would be to find a tutorial to help you understand the programming logic and learn some code.

Thanks, I'll try that right away
