Get Radio Box Value

NZ_Kiwis

I've got a series of radio box's.

I know if I echo $_POST['2']; (being the pollID) it will echo 2 but how can i echo the selected value?

echo "<input name=\"$PollID\" type=\"radio\" value=\"$AnswerID\"> " . $row['PollAnswer'] . "<br \>";

You want all related radio inputs to have the same 'name' value. Otherwise it defeats the purpose of having radio inputs. For example:

<input type="radio" name="whatever" id="whatever_1" value="1" /> <label for="whatever_1">One</label>
<input type="radio" name="whatever" id="whatever_2" value="2" /> <label for="whatever_2">Two</label>
<input type="radio" name="whatever" id="whatever_3" value="3" /> <label for="whatever_3">Three</label>

Then, once the form is submitted, you would get the selected value from:

$_POST['whatever'];

And how about checkbox's that are being displayed at run time?


<?php
require('../db.php');
$result = mysql_query ("SELECT * FROM forum_regions WHERE RegionActive = 0");
while($row = mysql_fetch_array($result)){
$RegionName = $row['RegionName'];
$RegionID = $row['RegionID'];

echo "<input name=\"$RegionID\" type=\"checkbox\" value=\"1\" />" . $RegionName . "<br />";
}
?>

how can i echo which ones are being ticked?

That depends on what the criteria is for the checkbox being checked. When should one of your checkboxes be checked as opposed to not being checked?

It will be checked if someone wants to set it's value to 1 in a database.

OK, I think this is what you're looking for:

<?php
   require('../db.php');

   $result = mysql_query ("SELECT * FROM `forum_regions`");
   while($row = mysql_fetch_array($result)){
?>
      <input name="<?php echo $row['RegionID']; ?>" type="checkbox" value="1"<?php echo ($row['RegionActive']) ? ' checked="checked"' : ''; ?> /> <?php echo $row['RegionName']; ?><br />
<?php
   }
?>

thanks but how do i get it the value is 1 or 0 in a $vairable so i can insert it into a SQL command.

If the checkbox "isset" it will equal 1, otherwise is will equal 0:

<?php
require('../db.php');

// Process form results
$result = mysql_query ("SELECT * FROM `forum_regions`");
while($row = mysql_fetch_array($result)){
   if(isset($_POST['RegionID'])){
      $value = 1;
   } else {
      $value = 0;
   }
   // ...
}
?>

I think you are on the right track butthat code does not give the name of the check box, ie: car, plane, train, boat on each loop does it? so i would need to do $row['car']; at some point as well wouln'd i?
