[lumpylumpy]

Hi to all, my captcha was working great until it stoped.I dont hnow why or wen.I have ZenCart 1.38a
I checked all the filles and fonts and they whare OK and i place.
Captcha in on every page but i get ENABLE THIS PICTURE and nothing shows up, not even on captcha_test.php or captcha_debug.php.
I installed the new version Captcha using TTF & GD 2-9, still the same problem.
I installed the older version again, still the same problem.
I have reverted to backups, still the same problem.
I have checked the server configuration and i have GD libraries enabled.
I dont know what else to check.I have tried everything from this thread.
Somebody has eny suggestions? any....
Thanks, Zoli.

Zoli,

My first impression is that, if you did absolutely nothing to your store before the event, then you ought to look at your server/service provider and ask if they did anything to their server configurations.

Explain that you're using zen cart (they ought to be familiar with it) and see what they say.

From your post I wonder if you've tried a clean installation from your offline copy of the cart? You DO have a full copy of all your store's original files from before the problem?

Hi worldmaker, i did not try a full backup off my shop, i have done that now and the captcha WORKS.
Now all i have to do is to search and compare.Since the backup i have done some customisation to my cart.
I am going to dig in to this now.....
THANK FOR THE TIP.

Glad I could help.
The easiest way to deal with any upgrading is to use a test copy of your store, either online alongside your live store, or offline on a standalone PC. That saves a lot of problems when you do carry out a major change, or upgrade.

I'm having a problem with the Contact Us page.

I seem to have installed the mod. correctly, and there are no other mods., etc., running on my site to cause conflicts.

Captcha works on the login function, and it works on the captcha_test.php file, but it doesn't work on the Contact Us page for my test shop.

The captcha IS appearing but it's not locking out users (Test dummy one - me)

This means that anyone can enter a message and hit send without completing the captcha and they'd be allowed to go ahead.

I'm running it on Zen 1.3.8a with no other problems (because I've locked everything else out).

I haven't made any modifications that I can recall on the Contact Us template page.

Any thoughts or suggestions?

Worldmaker,

I had more-or-less the same problem and found this thread, which showed me what I did wrong:
http://www.zen-cart.com/forum/showth...CHA+validation

Basically, I re-named the old version of the pre-existing file, in its pre-captcha form to *filename_BAK.php*, to have it as a backup, while using the original *filename.php* for the new version of the file with captcha.

Removing that original, renamed file, so only the updated, captcha'd version was in the directory solved the problem. Now it works like a charm. Check out that thread shown above. If it does not help everyone, it deserves a review anyway, as it solved the problem for me!

Cheers, chrx

Chrx,

Thanks for the thought, I'd done the same and only after advice from Andrew did I understand the problem and remove the backup copy of my original, unedited, file, but it's nice to know there are answers elsewhere too.

And if you do still want to keep the original unedited version of your .php file the answer is to rename it "(myfile).php.backup" or similar to stop it from being recognized as a functional .php file.

This morning I added "Captcha clarification" copy in an effort to help our site visitors who may not understand what they are looking at. Believe me, they are out there! Just added it to the Contact Us page at this point...

Here's what it looks like:
http://www.bhjdynamics.com/index.php...age=contact_us

Here's what I added to file
includes/templates/our_template/templates/tpl_contact_us_default.php:
------------------------------
// BOF Captcha
if(is_object($captcha)) {
?>
<br class="clearBoth" />
* ADDED THIS LINE --->* <?php echo '<br />' . INTRO_CAPTCHA . '<br /><br />'; ?>
* EDITED THIS LINE --->* <?php echo $captcha->img() . '<br /> &nbsp;' . TEXT_CAPTCHA_REDRAW . ' &nbsp;'; ?>
<?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
}
// EOF Captcha
------------------------------

Here's what I added to file
includes/languages/english/extra_definitions/captcha.php:
------------------------------
* ADDED THIS DEFINITION --->* define('INTRO_CAPTCHA', 'In our effort to combat email spaming, BHJ now requires all contact emails to include verification. Please type the letters and numbers shown below into the verification code field.');

* ADDED THIS DEFINITION --->* define('TEXT_CAPTCHA_REDRAW', '(If this image is unclear, click the redraw button.)');

* EDITED THIS DEFINITION --->* define('TITLE_CAPTCHA', 'Enter verification code shown above:');
------------------------------

Just thought I'd post this, in case anyone else wants to tailor the user experience.

Cheers,

Chrx,

Couldn't you have just added the formatted text to the tpl....php file? Saves having two files edited and the problems of keeping track of your edits?

Chrx,
Couldn't you have just added the formatted text to the tpl....php file?

I'm just trying to stay within the established methodology of the ZC workspace.

Doing it the way I did will enable me to drop the same definitions into the other Captcha-edited templates (Tell A Friend, Reviews, etc.) and when I need to make a global copy edit, I can do it in the referenced language definition file only (captcha.php) and it will be reflected in all templates containing that definition. Beats having to manually edit every template.

Ahhh, dynamically-generated web pages!

Regarding keeping track of my edits - I add my name to the header of every ZC file I edit. Then, if I need to run an upgrade or archive all edited pages for any other reason, I just search for my name in Admin/Tools/Developers Toolkit and it shows everything.

Ooooo, I LIKE that idea!
