if( isset($_POST['Submit'])) {
   if( $_SESSION['security_code'] == $_POST['security_code'] && !empty($_SESSION['security_code'] ) ) {
		// Insert you code for processing the form here, e.g emailing the submission, entering it into a database. 
		//echo 'Thank you. Your message said "'.$_POST['message'].'"';

		echo "<script type='text/javascript'>
    alert('".json_encode($_SESSION['security_code'])."');
</script>";
		unset($_SESSION['security_code']);
   } else {

Solution 1

hi,

one of the way:you can use hidden variable
assign the session value in hidden variable and use document.getElementById()
to fetch the value form hidden variable.
but this is not a secure way :(
any way you are assigning session variable value in JS user can also read the value from JS variable

adding with vyas_partik20 here is a simple example:

PHP

$data='some data';
?>

<script>
var data="<?php echo $data??>"; //if there is new line you need to do extra care :D
</script>
