append a loop variable in a radio button name

[romano2717]

I used the for loop variable $i to each radio button so that each radio button will have a unique name. the problem now is how can i display the values selected in the radio button on the same page as where the form is located.
your help is greatly appreciated.. thanks
here's the code:
NOTE: this code is cut short, i only posted the part where i got stuck

<?php
        if(isset($_GET['sub'])){
            $num = $_GET['num'];
            $num = 2;
            for($i=1; $i<=$num; $i++ ){
                echo '
                <tr>
                    <td align="center">
                        Question no.: '.$i.'
                        <br>
                        A.<input type="radio" name="'.$i.'[]"   
value="A"><br>
                        B.<input type="radio" name="'.$i.'[]" value="B"><br>
                        C.<input type="radio" name="'.$i.'[]" value="C"><br>
                        D.<input type="radio" name="'.$i.'[]" value="D"><br>
                    </td>
                </tr>';
            }
        }
        if($_GET['eva']){
            $choice = $_GET['$i']; //this is where i got stuck
            foreach($choice as $opt){
                echo $opt;
            }
        }
    ?>
    <tr>
        <td align="center">
            <input type="submit" name="eva" value="evaluate">
        </td>
    </tr>

Hi,
A few problems with yout mark up....
the radio buttons need to be in a group with the SAME name. the whole thing about radio buttons is that they are grouped together, (eg. male female, single married). if you want them to be selected individualy you will need to use a "checkbox".

But back to your problem so having given your radio buttons a static name you can get it from the forms method variable but only on the post back.

If your like me i can understand code better than conversation so here is some code....

The HTML

A.<input type="radio" name="'myradioButton" value="A">A<br>
B.<input type="radio" name="'myradioButton" value="B">B<br>
C.<input type="radio" name="'myradioButton" value="C">C<br>

The PHP

<?php
if (IsSet($_GET("myradioButton")){
?>
the value of the radio buttons was....<?php echo $_GET("myradioButton"); ?>
<?php } ?>

the problem is i dont know how to get the values of the selected radio buttons since the name of each radio buttons has a variable appended to it. can anyone help me with this?

Well don't give a unique name to the input.

name="something[]"

Will do just fine.

but i need to have a unique name for each set of radio buttons, so for every loop it will create four radio buttons with unique names.

Hi,
are the radio button mutually exclusive to eachother? or do you want them grouped together?

i want them grouped together so i will have a set of radio buttons consist of four radio buttons.. imagine an exam.. you have 5 questions with 4 choices each, so each question which is consist of 4 choices you can only select one radio button each question.

Hi,
Refer to my previous post.

All the ones in the same "answer" for the question will need the same name like question1, and the value between the tags will be the value displayed and posted back to the server. if you post all relevent code i will show you.
