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..

Code:

<?php // BOF Captcha if(is_object($captcha) && (!$_SESSION['customer_id'])) { ?> <?php echo $captcha->img(); ?> <?php echo $captcha->redraw_button(BUTTON_IMAGE_CAPTCHA_REDRAW, BUTTON_IMAGE_CAPTCHA_REDRAW_ALT); ?> <label for="captcha"><?php echo TITLE_CAPTCHA; ?></label> <?php echo $captcha->input_field('captcha', 'id="captcha"') . ' ' . TEXT_CAPTCHA . ''; ?> <?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..

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..

Quote:

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

Quote:

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

replace it with the following code..

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..

Code:

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!

Re: Captcha using TTF & GD

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!!!)

Re: Captcha using TTF & GD

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

Quote:

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

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

Code:

if (CAPTCHA_RETURNS != 'false') {

Glade it helped!

Re: Captcha using TTF & GD

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.

Code:

captcha::__set_state(array( 'captchaCode' => 'K97W', 'captchaCode_length' => 4, 'img_width' => 240, 'img_height' => 50, 'img_type' => 'jpeg', 'chars_min_size' => 0.6, 'chars_max_size' => 0.8, 'chars_shadow' => true, 'chars_rotation' => 23, 'noise' => 30, 'backgroundColor' => array ( 0 => array ( 0 => 220, 1 => 220, 2 => 220, ), 1 => array ( 0 => 255, 1 => 255, 2 => 255, ), ), 'linesColor' => array ( 0 => array ( 0 => 150, 1 => 150, 2 => 150, ), 1 => array ( 0 => 185, 1 => 185, 2 => 185, ), ), 'textColor' => array ( 0 => array ( 0 => 30, 1 => 30, 2 => 30, ), 1 => array ( 0 => 199, 1 => 199, 2 => 199, ), ), 'dir_fs_fonts' => 'C:/wamp/www/CLEAN MODIFIED SITE/fonts/', 'ttf_list' => array ( 0 => 'C:/wamp/www/CLEAN MODIFIED SITE/fonts/VERDANA.TTF', ), 'max_try' => 5, 'failure_proc' => '', 'quality' => 60, 'chars' => array ( 0 => '1', 1 => '2', 2 => '3', 3 => '4', 4 => '5', 5 => '6', 6 => '7', 7 => '8', 8 => '9', 9 => 'A', 10 => 'B', 11 => 'C', 12 => 'D', 13 => 'E', 14 => 'F', 15 => 'G', 16 => 'H', 17 => 'I', 18 => 'J', 19 => 'K', 20 => 'L', 21 => 'M', 22 => 'N', 23 => 'O', 24 => 'P', 25 => 'Q', 26 => 'R', 27 => 'S', 28 => 'T', 29 => 'U', 30 => 'V', 31 => 'W', 32 => 'X', 33 => 'Y', 34 => 'Z', ), '_background' => NULL, 'img' => NULL, '_gd_version' => array ( 'GD Version' => 'bundled (2.0.34 compatible)', 'FreeType Support' => true, 'FreeType Linkage' => 'with freetype', 'T1Lib Support' => true, 'GIF Read Support' => true, 'GIF Create Support' => true, 'JPG Support' => true, 'PNG Support' => true, 'WBMP Support' => true, 'XPM Support' => false, 'XBM Support' => true, 'JIS-mapped Japanese Font Support' => false, 'version' => '2', ), 'debug' => true, 'img_href' => 'http://localhost/CLEAN MODIFIED SITE/captcha_img.php?zenid=cjr7niaienpcclr2hb9hmqqdb0', 'imageColorFunc' => 'imagecolorallocate', ))

Any suggestions on what could be the problem?
TIA

Re: Captcha using TTF & GD

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.

Re: Captcha using TTF & GD

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). :bangin:

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.

blank pages

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 :P)

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. :blink:

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! :unsure:

Re: Captcha using TTF & GD

Nevermind, everyone. ... :oops:

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! :bigups:
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.
