$a = $_GET["Region"];
?>
<p><a href="page.php?region=<? echo $a ?>">GO</a></p>
</form>
this is my code but it is not working i cannot echo $a in my browser.
OK I think what you need is this:
[PHP]
<form id="all_region" name="all_region" method="GET" action="">
<label>
<select name="region" id="region">
<option value="****">[Select]</option>
<option value="LUZON">Luzon</option>
<option value="VISAYAS">Visayas</option>
</select>
</label>
<?
if(isset($_REQUEST["region"]))
{
$a = $_REQUEST["region"];
?>
<p><a href="page.php?region=<? echo $a ?>">GO</a></p>
<?
}
else
{ ?>
<input type="submit" value="Update link">
</form>
} ?>
[/PHP]
I have not tested this, but first you need to submit the information to the same page (action=""), then using the if(isset(bla)) code, capture the submitted 'region' value.
