Problem with radio buttons in form

maciek4

I have a form where I have a field with 4 radio buttons containing options:

A
B
C
D

The field is required so if no option is selected then an error message appears in red color. When the user selects one option and clicks submit I want it to be sent by mail to my account.

$progress = array();
$progress_error = false;

if(!isset($progress) || !is_array($progress) || empty($progress)) {
        $progress_error = true;
        $error = true;
    }

if(!$error) {
$mailBody .= "Rate your progress:\n";
        if(isset($progress['A'])) $mailBody .= "- A\n";
        if(isset($progress['B'])) $mailBody .= "- B\n";
        if(isset($progress['C'])) $mailBody .= "- C\n";
        if(isset($progress['D'])) $mailBody .= "- D\n";

<INPUT TYPE="radio" NAME="progress" value="A" <?echo isset($progress['A']) ? 'checked' : ''; ?>>&nbsp;A <br>
<INPUT TYPE="radio" NAME="progress" value="B" <? echo isset($progress['B']) ? 'checked' : ''; ?>>&nbsp;B<br>
<INPUT TYPE="radio" NAME="progress" value="C" <? echo isset($progress['C']) ? 'checked' : ''; ?>>&nbsp;C<br>
<INPUT TYPE="radio" NAME="progress" value="D" <? echo isset($progress['D']) ? 'checked' : ''; ?>>&nbsp;D<br>

The problem is that all those options have the same name="progress" so an error message appears. If I give unique names to each option then it works fine but then the user can select all the options altogether A,B,C,D and I only want him to select one of these options. How can I fix it? 🙁

I almost managed to fix it. Radio buttons cannot be arrays because you ca only select one option. So I put:

$progress = ""; instead of $progress = array();

the problem that I have now is that I want it to be required to select it so that nobody leaves it unselected and clicks 'submit'.

if(!$progress) {
$progress_error = true;
$error = true;{

when I leave it unselected I get:

Notice: Undefined variable: progress in

Then make one of the options as checked then unless the user unselects the default value you will always have that value available.

<input type='checkbox' name='test[]' value = 'A' checked />A<br />
<input type='checkbox' name='test[]' value = 'B' />B<br />
<input type='checkbox' name='test[]' value = 'C' />C<br />
<input type='checkbox' name='test[]' value = 'D' />D<br />

This way $_POST[test][0] will always at least have A as a value.
