hi to all.
i am trying to do form validation through javascript and captcha using php.
when i try to alert for invalid security code, if thecode is correct also, it is giving alert boxes of invalid code and when i click ok button, page is redirecting to the next page.
my form code is
<input type="submit" name="submit" value="submit" onclick="chk();">
chk is a javascript function
PHP Code:
function chk()
{
alert("<?php chk1(); ?>");
}
it is calling a function named chk1. it is php function
<?php
function chk1()
{
if( $_SESSION['security_code'] == $_POST['security_code'] )
{
echo 'Thank you.code is valid';
header("Location: process.php");
} else {

} }
?>
