Captcha using TTF & GD

DivaVocals:

Apparently the answer is that the text on the forms is a typo.:smile: No worries..
There was no typo. It said "case insensitive." :wink:

I feel for you. I'm so glad I'm my own boss now. :smile:

KTNaturals:

There was no typo. It said "case insensitive."It's still the wrong text.. That means it's still a typo..:yes:

KTNaturals:

I feel for you. I'm so glad I'm my own boss now.Sorry for me??:smile: For trying to answer my client's questions?? For not having a perfect client?? No reason to feel for me.. It's part of the cost of being the boss ya know??:yes: All my clients can't easy to work with.. though it is something I strive for:laugh:.. for the record.. I AM my own boss too or was that not clear??:wink:

I thank you all for your responses.. I have a clear idea on how to proceed..:cool:

When uploading, do I need to upload the files: captcha_debug.php, captcha_img.php or captcha_test.php? Also, am I right in thinking that the 'fonts' folder goes into the top root directory where 'includes' is?

If anyone's interested in using the Captcha feature with their Return Authorisation Request page..this is how I did it (it works great for me).

First modify your header_php.php file located in
\includes\modules\pages\returns
so it looks something like this (only modified part of file shown):

<?php

 */
require(DIR_WS_MODULES . zen_get_module_directory('require_languages.php'));

// BOF Captcha
if(CAPTCHA_CONTACT_US != 'false') {
	require(DIR_WS_CLASSES . 'captcha.php');
	$captcha = new captcha();
}
// EOF Captcha

  //require('includes/application_top.php');
if (REGISTERED_RETURN == 'true'){
  if (!$_SESSION['customer_id']) {
    $_SESSION['navigation']->set_snapshot();
    zen_redirect(zen_href_link(FILENAME_LOGIN, '', 'SSL'));
  }
}


  $error = false;

  if (isset($_GET['action']) && ($_GET['action'] == 'send')) {
    $name = zen_db_prepare_input($_POST['contactname']);
    $email_address = zen_db_prepare_input($_POST['email']);
	$telephone = zen_db_prepare_input($_POST['telephone']);
    $street_address = zen_db_prepare_input($_POST['street_address']);
    $city = zen_db_prepare_input($_POST['city']);
    $state = zen_db_prepare_input($_POST['state']);
    $postcode = zen_db_prepare_input($_POST['postcode']);
    $order_number = zen_db_prepare_input($_POST['order_number']);
    $value = zen_db_prepare_input($_POST['total_value']);
    $item_number = zen_db_prepare_input($_POST['item_number']);
    $item_name = zen_db_prepare_input($_POST['item_name']);
    $action = zen_db_prepare_input($_POST['action']);
    $reason = zen_db_prepare_input(strip_tags($_POST['reason']));

  $zc_validate_email = zen_validate_email($email_address);

// BOF Captcha
  if (is_object($captcha) && !$captcha->validateCaptchaCode()) {
    $error = true;
    $messageStack->add('returns', ERROR_CAPTCHA);
  }
// EOF Captcha
	
  if ($zc_validate_email and !empty($reason) and !empty($name) and !$error) {

Don't forget the very last line

Note that the code above will configure it so that in admin when you turn off the captcha on the Contact Us page, it would also turn off the captcha on the Returns page as well. I have a feeling you would need to edit the SQL to have a separate setting (something I wasn't sure on how to do).

Then in..
includes\templates\YOUR_TEMPLATE\templates
edit tpl_returns_default.php so it looks like this:

<label class="inputLabel" for="entry-action"><?php echo ENTRY_ACTION; ?></label>
<?php echo zen_draw_input_field('action', $default_action, 'size="20" id="entry-action"') ; ?>

<?php
}	
?>

</fieldset>
<br class="clearBoth" />
<fieldset id="write">
<legend><?php echo ENTRY_REASON . '<span class="alert">' . ENTRY_REQUIRED_SYMBOL . '</span>'; ?></legend>
<?php echo zen_draw_textarea_field('reason', '30', '7', '', 'id="reason"'); ?>
</fieldset>

<?php
// BOF Captcha
if(is_object($captcha)) {
?>
<fieldset>
<legend><?php echo TITLE_CAPTCHA; ?></legend>	
<?php echo $captcha->img(); ?>
<?php echo $captcha->redraw_button(BUTTON_IMAGE_CAPTCHA_REDRAW, BUTTON_IMAGE_CAPTCHA_REDRAW_ALT); ?>
<br class="clearBoth" />
<label for="captcha"><?php echo TITLE_CAPTCHA; ?></label>
<?php echo $captcha->input_field('captcha', 'id="captcha"') . ' <span class="alert">' . TEXT_CAPTCHA . '</span>'; ?>
<br class="clearBoth" />
</fieldset>
<?php
}
// BOF Captcha
?>

<br class="clearBoth" />
<div class="buttonRow forward"><?php echo zen_image_submit(BUTTON_IMAGE_SEND, BUTTON_SEND_ALT); ?></div>
</fieldset>
<?php
  }
?>
</div>
</form>
<div class="buttonRow back"><?php echo zen_back_link() . zen_image_button(BUTTON_IMAGE_BACK, BUTTON_BACK_ALT) . '</a>'; ?></div>
<br class="clearBoth" />
</div>

I'm quite sure that's all I did. Please state if it works ok for you, to confirm the instructions are correct and complete.

Great info.. Wish I had this info beforehand.. I usually got around this by only allowing registered users to access the returns page.. Gonna definitely bookmark your instructions to try out on my test cart for future use..:yes:

DivaVocals:

I consider customer satisfaction a meaningful effort. :blush: But thanks for your response.

Diva,

1. There is no need to explain your motivations.

2. My recommendation regarding investing time was to Andrew, not you. ;-)

3. One can say:

IS NOT CASE SENSITIVE

-OR-

IS CASE INSENSITIVE

Totatoes, Totatos

But if you want to make the mod case sensitive the PHP code is there for you to work with.

4. Just show your client some other forms protected by CAPTCHA and explain reasons needed. Should not be difficult to convince on the reasonableness of integrating captcha. But if client refuses, let it be.

Good luck,

Woody

Like I said.. I already worked out a solution, and have moved on to other things.. But thanks again for your input..:smile:

Spammers' bot cracks Microsoft's CAPTCHA

greetings :D

i added the updated captcha mod with the optional 'hide telephone'. i went to my site as a guest and the captcha does not appear on any applicable pages-contact, tell a friend, registration.

http://knottybynature-ny.com/index.php?main_page=

did i forget to modify a file? i loaded the original captcha program first, then overwrote it with the updated files. if necessary i can overwrite everything with the backup i did (smart little me) and start over, although i'd rather not :no:

thanks,

Hi,

is there still a place to download the last version of this add-on ?
The one from the download section seems old and the link in the first post is not working anymore :/

Hi,
I would like to use this contribution with ZC 1.3.8a. Only but important problem I have is that the image is not displayed. I have tried also captcha_test.php but image is missing too. I also tried to use link from source generated, like:

http://mysite/captcha_img.php?zenid=uj6babhkegc57ifmn2pp177qa5&rand=0.412157001208472668

Browser offers to download the picture instead of displaying it. Downloaded picture is fine when jpeg set. Image viewer is complaining about corrupted header for png and gif. Have you ever seen such a behaviour ? Any idea what's wrong ?

Thanks
Vlad

Try captcha_debug.php

Hello,

Tried both these capchas - the older TTF one :: CAPTCHA using TTF & GD

And :: captcha-number-subject-combo-in-one-1.0

Both of them show the image fine but dont work :

You can still send an email through if there has been no validation code entered relating to what the captcha image is showing.

I tied the newer version first, uni stalled then tried to older version.

Any ideas? V1.3.7.

Thanks.

Hi Andrew,

The output from captcha_debug.php was displayed as text. See attachment.

Thanks

Vladimir

Ruff...sniff sniff...

Can you tell me what this means

Fatal error: Call to a member function close() on a non-object in C:\wamp\www\intimateu\includes\classes\captcha.php on line **337

I need some help fixing this.

Please.
**

Excuse the bump folks,

After I commented out line 337 in includes/classes/captcha.php

like so

// $za_dir->close();

It began to function normally.
Otherwise the error as in the previous post.
