Captcha using TTF & GD

[Donn]

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.........

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

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

 if($this->debug) {
      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'], '"');
  if ($count == 1)
  {
    if(substr(stripslashes(trim($_GET['keyword'])), 0, 1) == '"')
    {
      $_GET['keyword'] .= '"';
    }
  }
  $_GET['keyword'] = stripslashes($_GET['keyword']);
}

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???

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.

Hi,

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!

Hello orange_juice,

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,
Orange_juice

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!

this is just strange . I installed this mod on 138a , 139a and b with no problem .. i just installed this mod on 139c , file base is working but when i try to install SQL patch using zc sql patch installer . i get this error .

ERROR: Cannot insert configuration_key "" because it already exists

i have gone through everything .. new 139c database has not been altered , this mode is a first one that is adding / modifying this Database .
any clue as what is wrong here ?
previous installation was done on exact same test server with no problem

Resolved: Corrupt VERDANA.TTF file.

[dimsumgurl]

Anyone got ideas on how to get the image to display if (as Dennis points out above) the Customer Approval Status - Authorization Pending or Customer Shop Status - View Shop and Prices are set to 1 (must be authorized to browse) and/or (must login to browse).

I need the restrictions on access, but I ALSO need captcha...

Hello!! I also require help with this too!! This is a frustrating one because I want to limit who can view my products and keep out those bots!

THANK YOU!!!
