Single radio button selection per group

[Thauwa]

I need the user to select only one radio button out of a group of four radios.

I have two groups of four buttoned radios.

How can this be achieved?

Thanks in advance!

Give them all the same name but different values:

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

 

To read:

$chosen=$_POST['myrad'];

Thanks for the help, it worked, but.... What if there are no values, due to inserting purposes? I mean, how do I insert a value into MySql from the radio button, like 'y' if the button is selected and 'n' for the rest?

Just store the button number in the database as you can see by reading the data which ones weren't selected!

 

No need to store "y" or "n" for the state of the radio buttons as only one radio button can be selected at any one time.
