[SOLVED] Small problem

[zamp0e]

I've done a form where the user can vote for wich alternative he think should win, and I have a little problem with it, Is it possible to change this form so you can only vote for one alternative at once ? If so, how ?

 

<?php

 

if (!isset($_POST['submit'])) {

    ?>

 

    <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST">

    <input type="checkbox" name="design[]" value="Stilig">Stilig

    <input type="checkbox" name="design[]" value="Snygg">Snygg

    <input type="checkbox" name="design[]" value="Helt OK">Helt OK

    <input type="checkbox" name="design[]" value="Lite wierd">Lite wierd

    <input type="checkbox" name="design[]" value="Asful">Asful

    <input type="checkbox" name="design[]" value="...">...

    <input type="submit" name="submit" value="Rösta!">

    </form>

 

<?php

    }

else {

    if (is_array($_POST['design'])) {

        echo 'You selected: <br />';

        foreach ($_POST['design'] as $a) {

          echo "<i>$a</i><br />";

}

  if($a==Stilig)

  {

  mysql_query("UPDATE roster SET antal=antal+1 WHERE id='1'")or die(mysql_error());

  }

        }

    else {

        echo 'Nothing selected';

}

   

}

?>

 

 

Thanks in advance.

Use SELECT multiple and then use PHP to check if the user selected more than 2. You can combine it with JavaScript to disable the selection of more than 2 options, but ultimately, you'll want PHP to do some verifications in case the user has JavaScript disabled.

Use radio-buttons instead of checkboxes?
