Radio buttons, how to determine

ScaryMind

This is probably easy if you know how 🙁

I want to have five radio buttons across the screen. The person viewing the screen can select one button, but not two etc. How do l do this via php or is this html. Also after some one has selected a button, how do l work out which one in a php variable.

See complete beginner at this, though l did work out how to connect to a MySQL database by reading past posts :p

Thanks in advance.

It's html. Name the radio buttons the same name, and they are grouped. html only allows one to be selected from the group.

<input type="radio" name="blah" value="1" />
<input type="radio" name="blah" value="2" />
<input type="radio" name="blah" value="3" />
<input type="radio" name="blah" value="4" />
<input type="radio" name="blah" value="5" />

5 buttons, same name, different values. Once submitted, check it like this

# POST or GET depending on your form method
if(isset($_POST['blah'])) { # one was selected
   echo $_POST['blah']; # display the value
}
