[SOLVED] captcha

[Lambneck]

 

The following processing code echo's "Correct!" on a new page when the form is submitted.

however when my form is submitted correctly the user should be taken to a thankyou.html page,

not a new page echoing "Correct!". this interfers with my form processing.

is there a way to have it print "Correct" next to the input field when

the user types in the captcha code correctly before the form is submitted?

or simply a way to keep it from interfering with the

processing of form data?

 

 

 

<?php
session_start(); //Start the session
$session = $_SESSION['captcha']; //Define the session set in image.php
$image = $_POST['image']; //Define the post
$image = md5($image); //MD5 encrypt the post

if ($session == $image){ //if they have put the right text in
echo "Correct!";
}else{
echo "Incorrect security code!";
}
?>

try :

 

<?php
session_start(); //Start the session
$session = $_SESSION['captcha']; //Define the session set in image.php
$image = $_POST['image']; //Define the post
$image = md5($image); //MD5 encrypt the post

if ($session == $image){ //if they have put the right text in
header(location: "thankyou");
}else{
echo "Incorrect security code!";
}
?>

 

 

that maynot be right

You would need to use javascript to dynamically print "correct" next to it if it's typed in right, before submitting.  But...a bot could easily just brute force your captcha until "correct" pops up on your screen...
