[SOLVED] INPUT TYPE=RADIO

[denoteone]

what sort of php if statement can I use to make sure that on submit the user has atleast select yes or no

 

<INPUT TYPE=RADIO NAME="otherdata" VALUE="Yes">YES<br/>
<INPUT TYPE=RADIO NAME="otherdata" VALUE="No">NO<br/>

would it check to see if it is null? any help would be awesome.

 

thanks,

Javascript, not html or php.

 

If you want php to check it (it would require a pagereload).

 

if (!isset($_POST['otherdata']) || ($_POST['otherdata'] != "Yes" && $_POST['otherdata'] != "No")) {
    echo "Required field missing.";
}

 

But you probably want Javascript instead.

A quick way to do this is just to use a default value. I don't know if this is the behavior you want, though.

 

<INPUT checked="checked" TYPE=RADIO NAME="otherdata" VALUE="Yes">YES<br/>

<INPUT TYPE=RADIO NAME="otherdata" VALUE="No">NO<br/>

premiso since the radio buttons are in a larger form on the submit of that form I just check to make sure that  variable other data is at least equal to one... That makes sense I am not sure why I thought it was harder.

 

thanks,
