**phpchild** · Jan 14 '13, 07:39 AM

Code:

<?php
$a;
if($a)
{
echo "want to use header to redirect";
}
?>
<html>
		<form action="aa.php" method="post">
		
		<input type="submit" value="submit">
		</form>
</html>

<?php
if(isset($_POST['submit']) && $_POST['submit'])
		{
				echo "okkk";
				$a=true;
		}
		
?>

out.... would be grateful if someone helps me here..thanks in advances...
