Will we have a captcha for the login page? v 3.3 /login ?

[Marius P.]

It should be an easy patch, as it's already done in com/com_register.php

not sure what you mean by easy patch. ??

Mario don't give you the 100% working code, he give you the idea how to use captcha for login..

Here is how you could add captcha to login page.

open /com/com_login.php

Find

Code Select Expand

$error='';

Add After

Code Select Expand

require_once(INC.'/recaptchalib.php');
$publickey = "6Lc-A84SAAAAAD3btrvWyQUi7MI6EX1fH_RE6p0U"; 
$privatekey = "private captcha key.. find in com_register.php file";
function add_rec($text) {
$text = $text.'<script type="text/javascript">
 var RecaptchaOptions = {     theme : \'clean\'  };
 </script>';
return $text;
}
add_filter( 'filter_extracss', 'add_rec' );
 $captcha =  recaptcha_get_html($publickey);

Find:

Code Select Expand

global $error;

Replace wiht:

Code Select Expand

global $error , $captcha;

Find:

Code Select Expand

<input type="password" name="password" class="validate[required] span12" placeholder="'._lang("Your Password").'">

Add After:

Code Select Expand

<div class="row-fluid top10 bottom10">      '.$captcha.'</div>

Thanks,

Awesome...
It almost worked...
The captcha shows up...
But it does not require me to validate it.
It will just log me in without having to use it.

Well, you can see he forgot to validate it.

Code Select Expand

/** Actual login **/
if(_post('password') && _post('email')){
if(user::loginbymail(_post('email'),_post('password') )) {
redirect(site_url().me.'/');
} else {
$error = '<div class="msg-warning">'._lang('Wrong username or password.').'<>';
}
}

Should become

Code Select Expand

  if(_post('password') && _post('email')){
$resp = recaptcha_check_answer ($privatekey,
                                $_SERVER["REMOTE_ADDR"],
                                $_POST["recaptcha_challenge_field"],
                                $_POST["recaptcha_response_field"]);
 
 
  if (!$resp->is_valid) {
    // What happens when the CAPTCHA was entered incorrectly
   $error = '<div class="msg-warning">The reCAPTCHA wasn\'t entered correctly. Go back and try it again
         reCAPTCHA error: ' . $resp->error.'<>';
  } else {
 
 
if(user::loginbymail(_post('email'),_post('password') )) {
redirect(site_url().me.'/');
} else {
$error = '<div class="msg-warning">'._lang('Wrong username or password.').'<>';
}
}
  
  }

I already added the code in my example page, but forgot to add the validate code in this post..
