The last two hours i've been trying to make my form work,
its contains two unchecked radiobuttons and a submit button.
The user is able to choose either one of the two
and send the form using the submit button.
I would like to check (checked="checked") the radiobutton the user
pickt _after_ submitting the form, but just can't get it to work.

So what is the secret?

Regards,
Samuel van Laere

<form action="apage.php">
<input type="radio" name="group1" value="Milk"> Milk<br>
<input type="radio" name="group1" value="Butter"> Butter<br>
<input type="Submit">
</form>

switch($_REQUEST['group1']) {
case 'Milk':
echo "You like milk!<br>\n";
break;
case 'Butter':
echo "You like butter!!!<br>\n";
break;
default:
echo "You don't like anything<br>\n";
break; //not needed, but a good habbit
}

A little function

function checkit($name_of_radiobutton,$val){
$checked=(isset($POST[$name_of_radiobutton])
&&$POST[$name_of_radiobutton]==$val)?"checked=\"checked\"" :"";
return $checked;
}

then in the code

<input type='radio' name='rb' value='foo' <?php echo
checkit('rb','foo);?>>
<input type='radio' name='rb' value='bar' <?php echo
checkit('rb','bar);?>>

Untested.

Thank you Geoff, thats just what I need!
Not bad for untested code though :)
