Answer 1

Himani ,
Try this. Hope it will be useful to you. Instead of text-area you can use drop-down.

Answer 2

Try this way gives you solution
<script type="text/javascript">
//javascript
function clicked_checkbox()
{
document.form.submit();
}
</script>
<?php
$hr = isset($_REQUEST['HR'])?$_REQUEST['HR']:false;
$guest = isset($_REQUEST['guest'])?$_REQUEST['guest']:false;
$visiter = isset($_REQUEST['visiter'])?$_REQUEST['visiter']:false;
//Prepare query with retrieved value and put value in Dropdown
$sql = 'select * from table ';
if($hr) { $sql .= "where user = '$hr'" };
if($guest) { $sql .= "where user = '$guest'" };
if($visiter) { $sql .= "where user = '$hr'" };
$objDB->SetQuery($sql);
$res = $objDB->GetQueryReference();
if(!$res)
exit("Error in SQL : $sql");
if($objDB->GetNumRows($res) > 0)
{
while($row = mysql_fetch_row($res))
{
print("<option value='{$row[0]}'>{$row[0]}</option>");
}
}
mysql_free_result($res);
?>
//on change of checkbox we'll call above function and set data to dropdown
<form name='form' method='get' action='#'>
<input type="checkbox" id="checkbox_HR" name="HR" value="true" <?php if($hr) echo "checked='checked'"; ?> onchange="return clicked_checkbox();">
<input type="checkbox" id="checkbox_guest" name="guest" value="true" <?php if($guest) echo "checked='checked'"; ?> onchange="return clicked_checkbox();">
<input type="checkbox" id="checkbox_user" name="visiter" value="true" <?php if($visiter) echo "checked='checked'"; ?> onchange="return clicked_checkbox();">
</form>
like this you can achieve :)
