I'm new in CI. It's impressive but I got a lot of trouble. I made a registration form and I put Captcha in it using javascript but I don't know how to validate. I would like to try CI way of making captcha and validating but I don't know where to start. Can anybody teach me?

First of all welcome to the CI forums!

I guess the best place to start is starting to read the CI user guide, especially the
sections "Controllers", "Views" and "Models".

To solve your problem read the section "Captcha Helper":
http://ellislab.com/codeigniter/user-gui...elper.html

In case you have problems to implement that code into your project, post your code
and we will try to help you.

You can't expect somebody doing the complete coding for you now.
But you can post the code you have right now, tell us
what error message you get or where the code isn't working
like expected. Then we should be able to help you finding
a solution.

@ 0077

It's pretty hard to read the code in an email. When posting here you have
to escape "<scr+ipt" tags for example.

What I see is not a codeigniter approach so I can't really help you with that.
All in all it should be possible to use the CI captcha helper without
destroying your page. What exaxtly happens when you try to use the CI helper?

Actually I got a lot of trouble on how to insert in my code. What I have sent you is just a part because the error occurred when I try to attach my file in posting.

@luckyfella73

I would like to thank you for your willingness to help a newbies like me,

When I made my program I use codeigniter, but upon validation I use javascript. Jut what I have sent to you...

It's pretty to explain when I don't know how to show you my codes.

That is what you just send to me - now everybody can try to help you Wink

But like I mentioned - this is no CI way to use the captcha validation.
You allways should validate server-side so I recommend to try it the CI way!

Code:
&lt;html&gt;

&lt;head&gt;

&lt;title&gt;Online Ticketing System: Development Environment&lt;/title&gt;

 &lt;base href="&lt;?php echo base_url() ?&gt;" /&gt;

 &lt;link rel="stylesheet" href="css/screen.css" type="text/css" media="screen"

title="default" /&gt;

 <scr+ipt src="js/jquery/jquery-1.5.2.min.js"

type="text/java+script"></scr+ipt>

 <scr+ipt type="text/java+script">

 $(document).ready(function(){

 $(".loading_icon").hide();

 $('#submit-button').click(function() {

 $('.loading_icon').fadeIn(4000);

 var card_type = $('#card_type').val();

 var card_number = $('#card_number').val();

 var expiration_date = $('#expiration_date').val();

 var cvc2_cvv2_code = $('#cvc2_cvv2_code').val();

 var security_code =$('#security_code').val();

 if(card_type=="" || card_type==null)

 {

 alert("Please select Card Type");

 return false;

 return false;

 {

 return false;

 }

 if(isNaN(cvc2_cvv2_code) || cvc2_cvv2_code<0)

 {

 alert("Invalid CodenPlease enter valid CVC2/CVV2 Code");

 return false;

 }

 if(security_code=="" || security_code==null)

 {

 alert("Please enter Security Code");

 return false;

 }

 if(terms_and_conditions.checked == false)

 {

 alert("You need to agree to Terms and Conditions before you can proceed to

payment");

 return false;

 }

 else{

 $.post('&lt;?php echo base_url(); ?&gt;fare_details/add_contact_information',

 {

 'card_type': card_type,

 'card_number': card_number,

 'expiration_date': expiration_date,
