Captcha using TTF & GD

I just wanted to say a big thank you to Andrew and everyone who has posted helpful fixes etc on this thread.

Today I successfully installed this mod, with one minor hiccup that this thread helped me address. In my case the mod accepted any entry as valid on all pages except "create account".

@AmandaGero - I don't know if you have resolved your problem or not but you seem to have the exact opposite of me so I was thinking it might be the same cause. The reason for me was that I had named my old header_php files as header_php_save. I deleted these and now everything works as intended.

Re: Captcha using TTF & GD

I get this error.
Fatal error: Call to a member function close() on a non-object in /home3/carbsfou/public_html/includes/classes/captcha.php on line 341

Re: Captcha using TTF & GD

Hello everyone,

I am trying to get this module installed, I changed the needed files, added the sql to the database but still no go, it shows up on the create account page, but keeps returning the message: "You did not enter the validation code correctly. Please, try again."

The "captcha_test.php" works great, can someone throw me a bone.

Here is a link to the page: https://www.ecobaba.biz/index.php?main_page=login

Re: Captcha using TTF & GD

I've searched the thead but, alas, no joy.

Have checked proper placement of all Captcha files and cannot find the reason why the text is showing instead og the redraw buttin:
/includes/templates/template_default/buttons/english/BUTTON_IMAGE_CAPTCHA_REDRAW
TITLE_CAPTCHA TEXT_CAPTCHA
The png file is attached

Thanks a pile

Re: Captcha using TTF & GD

remoteone:

Ive had Captcha installed for a while now and had noticed on my localhost windoze test machine that I often got an 'incorrect validation code message' for several attempts, even tho the code entered was correct. I have now had complaints from customers that they cannot log in due to the same problem on my Live site.
Ive now disabled CAPTCHA but getting the spambots again.
Any explanation why it works intermittently?

Yep just installed this, and it's happening to me too. Absolutely no idea why, and it would appear Andrew hasn't been checking this forum for a while.

In the interm I've turned it off. Luckily I only need it for the "non user review" page mod, and I can still filter at the admin level for spam, so it's not a biggie.

Re: Captcha using TTF & GD

Love this Mod. Running Zen-Cart v1.3.8a with no mod to the Contact Us form. Followed instructions exactly. Works great, with one problem:

In IE8, box is LEFT-justified under "Security Check:".

In Firefox 3.6, box is RIGHT-justified on same line as "Security Check:"

You can see this if you go to my site (using Firefox) at:
http://flairbyjdn.com/catalog/index.php?main_page=contact_us

Anyone else have this same problem? If you're only using IE, I would check your site with Firefox just to be sure you aren't experiencing the same problem I am.

Any ideas?

Re: Captcha using TTF & GD

Hi. I am using ZC 1.3.8A, with a number of mods, including Captha.

Everything worked fine, until I changed some .htaccess parameters.

I know it's only because of the changes I had made, as when I replace with the old .htaccess file, the Captcha again works 100%.

The .htaccess changes are needed. t I made many changes, however, and I'm wondering if anyone can steer me in the right direction, as far as which change, specifically, did this.

Nothing else on my cart, or the server, seems affected in any kind of negative way by the new .htaccess file.

When using my new .htaccess parameters, instead of displaying the Captcha image, I only see 'Enable This Picture' where the Captcha image should be, and the redraw button at right.

Clicking on that, it looks like the image will be drawn, it shows a rectangle the size of the Captcha block really fast, but then again reverts to the 'Enable This Picture' text.

What I seem to need to find out: How is the Catchpa image generated, as clearly I've disable the ability to do so on my server.

Re: Captcha using TTF & GD

Hallo, I would like to ask how I could add captcha verification to be checked by javascript?

My intension is to make certain that if a user inserts the wrong captcha code, the other entries in the form are kept intact instead of being erased and making necessary for the user to enter everything again from the beginning.

Kind regards,

OK; it was probably a bad idea to leave the cart like that for ANY period of time, but we were concerned about hacks, and in the meantime while securing the site, if someone couldn't log on, then that was OK. Now, I've removed the .htaccess code, and the Captcha STILL isn't working!!!!!!!!!!!!!!! :(:(:(:(:(:(:dontgetit

It's failing as it had been previously, with the new .htaccess changes. I KNOW that removing the new .htaccess code had fixed it instantaneously when I was messing with this, as I even posted that on this thread. (Just in case I am unsure, if I posted it ,I'm certain it was the case!) But now...it's seemingly stuck.

Can any .htaccess parameters stay in effect even after the .htaccess commands are removed???

I'm going to see if it was any of the suggested patches and security upgrades on this board that I installed. It doesn't make sense that it could be that, as changing the .htaccess file from new to old made the Catchpa work and then not work each and every time I tested before leaving the new settings in place.

Re: Captcha using TTF & GD

Running captcha_test.php as a stand-alone PHP file, still the Catchpa image doesn't display. Same as when it's generated on the cart. What does that tell me?? Does that mean it IS a server issue? All files are intact and remain in place; none have any added file length or show a recent modified date.

When I run captcha_debug.php, I get this message:

**Headers already sent in ******/includes/extra_configures/pci_patch_v13x_search.php on line 15 Warning: Cannot modify header information - headers already sent by (output started at *****/includes/extra_configures/pci_patch_v13x_search.php:15) in ********/includes/classes/captcha.php on line 288

Is this possibly because of the patch I applied, and NOT the .htaccess adjustment I had made, as I had thought earlier?
Any help would be **greatly **appreciated.........

Re: Captcha using TTF & GD

The below code from each of the two files returned in the error message is listed below. So far, I haven't figured anything out on my own with regard to this issue. Does anyone know anything about the patch, and why this might be happening? I don't see the identical commands, but then I'm only a PHP novice, and I'm not familiar with a lot.

Line 287- **********/includes/classes/captcha.php

      header('Content-Type: text/html');
    } else {
      @header('Content-Transfer-Encoding: binary');
      @header('Content-Disposition:attachment; filename=captcha_img.' . $this->img_type);
      @header('Content-Type: image/' . $this->img_type);
    }

Line 15 ****/includes/extra_configures/pci_patch_v13x_search.php

<?php
if (isset($_GET['keyword']) && $_GET['keyword'] != '')

  $count =  substr_count($_GET['keyword'], '"');

    {
      $_GET['keyword'] .= '"';
    }
  }
  $_GET['keyword'] = stripslashes($_GET['keyword']);

Re: Captcha using TTF & GD

I removed the patch from 27th June 2009, PCI Scans - (patch to handle low-priority warnings on search screen causing scan fail)
/includes/extra_configures/pci_patch_v13x_search.php

http://www.zen-cart.com/forum/showthread.php?t=130701

As soon as I did, the Captcha again resumed working 100%.

I do want the added protection of the patch that keeps certain error messages from appearing and revealing too much, but I also need the Catchpa functionality. :(:(:(

Any solution to this???

Re: Captcha using TTF & GD

Most of the problems with this CAPTCHA patch seem to be caused either by extra files that should be removed (e.g. renamed files remaining after a patch) or by extra characters being added to files during editing, for example carriage returns, line feeds or byte order markers. If you read back through this thread (all 54 pages!!!) you'll find a tool for removing invisible characters.

The tool worked for me, but I've since done a clean reinstallation of the whole shop and CAPTCHA then worked without using the tool.

It's definitely very flaky and causing a lot of grief.

I'm not sure if it's the CAPTCHA patch, Zen Cart or PHP that is the problem. Maybe if this CAPTCHA patch were part of the core it would help.

Re: Captcha using TTF & GD

Hi,

:frusty: I hope that someone can give me a helping hand. I have installed the captcha and as far as I've checked it works fine except for the contact us page. When a costumer has forgotten to fill in a field or make a mistake in i.e. the captcha code the page load again with the error messages. But the inquiry field returns emty so the user must type again his message.

I search on the internet for sites with contact page using the captcha and test to see what happen but my problem didn't show there.

I use the original files and have no modifications made to it.

Hope there is somebody out there who can give me a solution.

Thank you in advance!

It seems I've the same problem. The inquiry field returns empty when the user push the send button before filling in all the fields.

I was wondering if you solved this problem, and if so, how?

Thanks in advance for your reaction!
