nw_check.php
<?php
$con = mysql_connect("localhost","root","12345");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
?>
<html>
<body>
<form method="POST" action="nw_check_exec.php">
<input type="button" name="nw_update" value="NW_Update"/>
</form>
</body>
</html>
nw_check_exec.php
<?php
if(isset($_POST['nw_update'])){
echo("You clicked button one!");
//and then execute a sql query here
}
else {
echo" dhur";
}
?>
but for some reason the echo in the nw_check_exec.php is not being executed. please could you help.

I think it's because the input type is a "button" and should be a submit:
<input type="submit" name="nw_update" value="NW_Update"/>
