User Verification (Anti-Robot / CAPTCHA)

lankeeyankee:

I tried this method described here in this forum and suddenly every single spam email disappeared.

Seriously, use the technique from the thread I posted above and you will get rid of ALL spam without compromising your customer's experience.

The previous site for which I've got the task of replacing with Zencart (a trading eye site I believe), used a blank form field to stop spam bots. I'll post my questions on that thread.

I'm missing captcha on login page.

Could not see a reply to this.
Have just installed captcha_verification_for_zc139 and it works fine on contact us page but nothing on the registration/log in page.
What have I done wrong?:(

O.K. all sorted now. Found answer here

Has anyone been able to re-write this add-on, to work with zen-cart v1.5.0BETA on a test site?

A re-write for this add-on is almost complete for zen-cart v1.5.0BETA, and will be submitted for review in the next couple of days. There are some issues with coding for the Contact Us, and Tell a Friend pages, and should there be any delays for a release, it will most likely be due to those issues. I will post here again, once submitted to the Zen-Cart team for approval.

An update to this Mod has been submitted for review to the Zen-Cart Team this evening. The update covers Create Account, Contact Us, and Tell a Friend for Zen-Cart v1.5.0, currently still in BETA for testing.

I will post here, once it has been reviewed and published, and share the name of the new updated file.:smile:

The updated version of CAPTCHA Anti-Robot Registration v1.4, for Zen-Cart v1.5.0 has been approved and released for download by the Zen-Cart team. I will be starting a zen-cart forum, shortly for that version, and place the link/address for it here. Again, it is an update, utilizing v1.3 base code, which, without v1.4 may not have happened.

Installed module on Zen Cart 1.3.8, a little tired before get it working on the site in Lithuanian language but did it. Tested, captcha works fine. Only after couple of days started to get odd-product reviews in English, although the site is only in Lithuanian language, reviews clearly written by a robot, signed by dsfhskafh or similar names, 15-25 reviews a day ( in average website have only 100 visitors a day)...
Here is on of reviews: " I love radeing these articles because they're short but informative."
Any idea what's the problem?
Thank you.

Need to know: Which Captcha (Name and Version), PHP, and MySQL, you are using.

First things first. Did you verify in the Read Me First text file of your version Captcha, that it is compatible with the version of Zen-Cart you're using?

If it's compatible with Zen-Cart v1.3.8, double check your settings for Captcha from your store admin. Click 'Configuration', then 'CAPTCHA Validation', and ensure that Create Account option is set to True.

It's been along time since I have utilized Zen-Cart v1.3.8. The latest version that has been released is Zen-Cart 1.3.9h, and version 1.5.0 will be released once BETA testing is complete. Many security issues have been resolved since version 1.3.8. You may want to take the time and plan an update to the latest version of Zen-Cart to help resolve this issue, if everything else appears to be ok.

Last question. Has the bot been able to open customer accounts on your site? Or, has it been able to fill out reviews, without creating an account?

One last thing regarding your bot reviews. From your store Admin page, click Configuration, then Product Info, and verify that "Product Reviews Require Approval" is set with a '1' for True, and not a '0' for False. Atleast this way, they won't show up for others visiting your site to see, until you approve them, giving you a little more time until you're able to figure out what's going on regarding Captcha.

OK, what's happening can/may be the result of another Add-On which could be interfering with the Captcha PHP Code. I can help you look for this, but I would also need to know, All Add-Ons which you have added to Zen-Cart.

There is another item that you should also consider looking at, and that is your .htaccess file, if the server your using, uses Apache Software. Blocking Bad Bots with .htaccess is very helpful in todays market. Should you need some help with adjusting that file in order to block bots, or others, I have provided the following Online Instructional links below.

For assistance in writing .htaccess code:

http://httpd.apache.org/docs/2.0/mod/mod_access.html#deny

http://www.ipdeny.com/

http://www.darrinward.com/blog/seo/bad-robots-prevention

http://www.electrictoolbox.com/apache-allow-deny-ip-address/

You will find that with Zen-Cart, and many Add-Ons, you will still need to add additional security coding to .htaccess to aid in putting a stop to hackers, and just plain nuisances. Which even if there are no conflicting code issues with other Add-Ons that you have in place, and if Captcha seems to be working correctly, without adding additional coding in .htaccess to block unwanted computers, or people, it can still be easy for them to get in, and be annoying.

I hope this helps to point you in the right direction to resolve the issue your having.

In addition to everything else regarding your issue with Captcha, you should post your problem, with the version of Captcha you have, in the forum for that type and version.

Even though, those of us in this one, may be able to figure out how to resolve your problem, it's likely someone else has had the same problem who is in the forum for your type and version of Captcha, and the resolution for it, may already be posted there when you check it out. And if not, should someone have the same problem in the future, it would make it easier for them to find the solution, once it is resolved. The forum for your type and version of Captcha is located at: http://www.zen-cart.com/forum/showthread.php?t=59539&highlight=Captcha+TTF .

It's not that we don't want to help, but we need to make sure that the information is posted in the right location, to make sure that everyone who needs to know how to resolve the problem for the specific type and version of an add-on, can find the appropriate information for the issue.

Questions regarding version 1.4 of this module, for Zen-Cart v1.5.0, should be posted in the new thread located here: http://www.zen-cart.com/forum/showthread.php?t=186274

Uh oh, something went wrong! :shocking:

I really need some help, want to thank you in advance for taking the time to look at this.

Ok, I have a ZC 139h and I just installed CAPTCHA User Verification Version 1.3. I downloaded this CAPTCHA here (not the version for ZC 1.5.0 but the version just below):
http://www.zen-cart.com/index.php?main_page=product_contrib_info&products_id=325

CAPTCHA is installed and appears to be working just fine for Contact Us. However, it is messed up on Tell A Friend.

PROBLEM:
No CAPTCHA shows up on Tell A Friend. But if you fill it out and click SEND, it kicks back 2 errors.
"You have not entered a validation (CAPTCHA) code."
"You have entered an incomplete or incorrect validation (CAPTCHA) code."

Can you tell me what I did wrong?

Here is a link to a product on my site (click TELL A FRIEND for a demonstration of the problem):

I wish there was some way to delete the post above, I have gotten rid of the CAPTCHA entirely and reverted back.

I have decided to go with the CSS method.... AWESOME! Seems way more customer friendly to my site visitors.

Anyway, please don't waste your time answering my above questions as I have changed directions.

Thanks,
Mike

It would appear that, relating to your post previous to this one, that you have adjusted your image size from the original 30 x 30px, to 100 x 80px. I would suggest searching your site for the 100 x 80px settings, and see what you find, and, how it would effect your validation image folder. Perhaps you have a css file creating a problem?

In regards to your Create Account page not showing the CAPTCHA, though not included in the original info for the file, you must set your Login Page to "Split", or, it will not show on the Create Account page due to the settings of the file. Log into your Admin, click on Configuration in the upper left corner, select Layout, and towards the bottom of the page, change the setting of your Login Page to TRUE, for the Split Page option. Then when someone goes to create an account, they will see that at the bottom of the page, after filling out their information.

don't know if I'm looking in the right place but the only mention of 100x80px is the small image setting in admin at that was the default setting.
