Captcha using TTF & GD

[davewest]

Hello,
I wanted to add this option to my return authorization form. I have search for link with instructions..but couldn't find any... does anyone know how to get this to work with return authorization form? I tired but to no avail .

thanks nicole

If it's the Return Authorization by Clyde, then for tpl_returns_default.php add the following, I placed mine just above the submit button..

<?php
// BOF Captcha
if(is_object($captcha) && (!$_SESSION['customer_id'])) {
?>
<br class="clearBoth" />
<?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"') . '&nbsp;<span class="alert">' . TEXT_CAPTCHA . '</span>'; ?>
<br class="clearBoth" />
<?php
}
// BOF Captcha
?>

Then for the header file in >modules/pages/retuns/header_php.php you need to add it in two places, first anywhere near the top this section of code..

//BOF Captcha
if((CAPTCHA_RETURNS != 'false') && (!$_SESSION['customer_id'])) {
    require(DIR_WS_CLASSES . 'captcha.php');
    $captcha = new captcha();
}
// EOF Captcha

  $error = false;

I did mine just above this line..

if (isset($_GET['action']) && ($_GET['action'] == 'send')) {

Notice the CAPTCHA_RETURNS in the if statement, this turns it on or off through admin. if you don't do a SQL statement to add this, you'll need to change it to something else like CAPTCHA_CONTACT_US which has an admin control.

Look for this line

if ($zc_validate_email and !empty($reason) and !empty($name)) {

replace it with the following code..

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

To turn it on or off in admin.. add a sql statement using the Zen-Cart Sql Patches tool. Please backup your database before doing this... you never know when something will go wrong..

SET @configuration_group_id=0;
SELECT (@configuration_group_id:=configuration_group_id) FROM configuration_group WHERE configuration_group_title= 'CAPTCHA' LIMIT 1;

INSERT INTO configuration (configuration_id, configuration_title, configuration_key, configuration_value, configuration_description, configuration_group_id, sort_order, date_added, use_function, set_function) VALUES 
(NULL, 'Return Authorization', 'CAPTCHA_RETURNS', 'true', 'Activate Validation on Return Authorization', @configuration_group_id, 23, NOW(), NULL, 'zen_cfg_select_option(array(\'true\', \'false\'),');

Again... BACKUP before running the SQL statement.. I do my testing on a testing server before making any changes to a live site!

I usually make my Return Authorization form available only to registered users, but I have a current client who is insisting on Captcha even with this option activated.. So this is SWEEEEEEEEET!!! Thanks a bunch.. (BOOKMARKING THIS!!!)

Keep in mind that this line turns it off for log in customers.

if((CAPTCHA_RETURNS != 'false') && (!$_SESSION['customer_id'])) {

If you wish to run it for all customers even log in ones, change it to this..

if (CAPTCHA_RETURNS != 'false')  {

Glade it helped!

Hi,
I was testing this on a clean install on my local server, and all was going well until I installed the "Display Inc/Ex Tax or VAT Prices" module. Now I get the "enable this picture" text instead of the image. I ran the captcha_debug.php, but it may as well be chinese.

Any suggestions on what could be the problem?

I'm also having the "enable this picture" issue. I've uninstalled and reinstalled multiple times. I've read all the pages. I've updated my .htaccess. I'm fairly confident it isn't a coding issue, as I've replaced the MYTEMPLATE/account code with my archived code after determining that I don't need it (just want the contact_us).

When I run captcha_debug.php it bounces me to my home page. Does that mean there are no errors?

When I look at the code in Firebug I see the image is secure (https). That is strange.

Thanks in advance for the help.

I also had the "enable this picture" problem, read the posts, tried different things and then realized- the captcha_img.php file needs to be uploaded to the root directory (or the same directory as /includes).

That may be obvious to some, but not to a layman like me. The readme file doesn't mention it and I thought it was part of the other non-upload files like install.slq, update, etc.

Hi all,
I'm trying to install this module on the NEW site I'm building, and I seem to have buggered something up with the install. The contact us page and the tell-a-friend page both come up completely blank. I've tried to search through this thread to help solve the problem, but in all honesty I'm a bit lost.

And I feel pretty silly saying this but I don't know how to run a debug file or whatever it is...

I'm running several mods, FEC, COWOA, and a few others that I'd honestly have to go and look up to find. The test site is at w w w . t i f f s t r i n k e t s . c o m / f r d t e s t (sorry I don't want it indexed )

Now, it doesn't break the account creation page, but the tell a friend and contact us pages come up completely blank. Oddly enough, there was ALREADY a 'captcha' edit in the tpl_modules_create_account.php file that I had in there... I'm not sure why. I am (almost) 100% sure that I have not tried to install ANY captcha module on this test site yet... I've only been working on it for a couple of months now. I do have a pretty bad memory, but not THAT bad.

I have tested it on the create-account page, and I do have to input the characters to create an account, so I know that part of it, at least, is working. It's really the 'contact us' page that I'm most worried about; I get the most problems from that page.

If anybody can help, I'd really appreciate it. Thanks all!

[misticloudz]

Nevermind, everyone. ...

I had renamed the captcha files in a way that the page was still loading them, and it broke it.

(more detailed explanation: I had made all of my edits but kept the original mod files, just renamed them as header_php.captcha.php etc. so I had the untouched mod files if I needed them, but this rename wasn't quite enough! I changed it to captcha.header_php.php or somesuch and now my page works again...)

Whew!
I always seem to figure out my own problems RIGHT after I make a forum post about it... :)

Always helps to talk it through.... also, file renaming for backups. Best to remove them to a backup set of your store or just remove the extension '.php' change it to something like'.bak' or '.old'. leaving the '.php' even renaming the file can lead to more problems.
