You can't in HTML alone. You would have to use JavaScript. Yeah, you can use the drop down list approach. I really REALLY hate it when developers go that route. I know WHY they do it, but it really makes for a crappy user interface. The one that really irks me is State. I can type NY in about...

Firebug should be pretty transparent. It certainly shouldn't (can't?) alter the users IP address. I think you really need to get the php guys to explain what is different in the data the get with FireBug vs without it. Are they really seeing a different IP? I very much doubt that, but if so...

If by active you mean only one of them can be checked, you don't need code for that. HTML knows how to do that already. Assuming you are talking about an asp.NET page here, just use an <asp:radiobuttonlist> on your page. If you are talking about raw HTML, just set the name attribute of each...

It's a poor way to do security, but it might work OK in a very limited area. User name/Password authentication is usually better. You are assuming you are limited to users who are given static IP addresses. Works OK in a small, isolated network. But what happens if more and more people want to...

XML is not a 'markup' language like HTML. XML is meant for sending data...raw data. How that data is to be displayed to a user isn't XML's business. XML has no concept of 'underline'. The whole idea behind XML really is that you separate the raw data, from how you want to display that raw...

You should send this question to [email protected] Although, let's face it...he probably won't read it or respond :-( But I wouldn't mind hearing his thoughts on this. HTML5???

Can you use a MySQL event? (I've never used them myself, so I don't know how well they really work in practice, but they look like exactly what you need here). I would think you could create an event that runs every X seconds and does an update on the table based on opening date being <...

A browser will make a request to your server, either a GET request (to load a page), or a POST request (to post form data to server). The browser expects an HTML document to be returned from that request, which it will then display. You can use PHP on the web server to generate the HTML code...

My computer seemed a tad sluggish tonight so I brought up task manager to see what was going on. It was running a constant 40% CPU use, and the culprit was Firefox. I had a number of tabs open, so I started closing them 1 by 1. Closing one of the YA! tabs brought it down to 20%. Closing the...
