Answer 1

Use jQuery.

Call change event of the drop down.

$(function(){
  $("[name=driver]").die('change').live('change', function(){
    var driver = $(this).val();
    if (typeof driver !== 'undefined') {
      window.location.href = 'YOUR_FILE.php?driver='+driver;
    }
  });
});

And

in your YOUR_FILE.php , get driver using $_GET['driver']

Or if you want the form to be more secure, take a hidden variable.

On change of driver , assign it the value of driver drop down.

And post the form.

In your PHP file, get it as $_POST['hid_driver'] .

U can add onclick function for the select field, try this way

<?php
//another select query goes here.

$query1= "SELECT  * FROM driver WHERE status='Available'" ;
echo '<td>'.'<select name="driver" onchange="window.location.href=\'db_confirm_booking.php?driver=' . $_POST['driver'] . '&id=\'+this.value">';
                        $result1= mysql_query($query1);
                        while($row1 = mysql_fetch_assoc($result1))
                                    {   
                                    echo '<option value="'.$row1["name"].'">'.$row1["name"].'</option>';    
                                    }
                                    echo '</select>'.'</td>';
echo'<a rel="facebox" href=db_confirm_booking.php?id='.$row["id"].'&driver='.$_POST['driver'].'>' . 'Confirm' . '</a>';

?>

try this code

<?php
//another select query goes here.

$query1= "SELECT  * FROM driver WHERE status='Available'" ;
echo '<td>'.'<select name="driver" 
onChange="window.location.href=this.value">';
$result1= mysql_query($query1);
while($row1 = mysql_fetch_assoc($result1))
{   
echo '<option value="db_confirm_booking.php?id='.$row["id"].'&driver='.$_POST['driver'].'">"'.$row1["name"].'">'.$row1["name"].'</option>';    
}
echo '</select>'.'</td>';
echo'<a rel="facebox" href=db_confirm_booking.php?id='.$row["id"].'&driver='.$_POST['driver'].'>
' . 'Confirm' . '</a>';

?>

example code

<select onChange="window.location.href=this.value">
<option value="www.google.com">A</option>
<option value="www.aol.com">B</option>
</select>

Answer 4

<select name="sel" id="sel" onchange="seturl(this.value)">
<option value=""></option>
</select>

<script>
function seturl(id)
{
  document.forms[0].action="test.php?driver="+id;
  document.forms[0].submit();
}
</script>

It will reload the page with driver name in url.
