Captcha using TTF & GD

[davewest]

But...the validation through CAPTCHA is not active, you can leave the field blank and the message is sent the usual way...any suggestion to have the verification working? (Using v.1.3.8a)

starks -- Look at your edits to see if you have them all in place. I have it installed on 1.3.8a and working.

Has there been any fix for the "Enable This Picture" problem with the Ultimate SEO module?

Jeff_Mash -- Still looking into it... I've been able to recreate the problem, just have to trace it back to the cause.

Thanks Dave. I will be anxiously awaiting your response. If you need me to verify anything, just let me know.

Ok, I am making SOME progress with the "Enable This Picture" error that you get when using Ultimate SEO's.

Right now, I am simply working with the captcha_test.php until I get it to work totally correct.

If you edit the captcha_test.php, do the following:

FIND:

$this->img_href = zen_href_link('captcha_img.php', zen_session_name() . '=' . zen_session_id(), 'SSL', false, false, true);

REPLACE WITH:

$this->img_href = original_zen_href_link('captcha_img.php', zen_session_name() . '=' . zen_session_id(), 'SSL', false, false, true);

That will make the image appear! However, now it doesn't matter what code I type in, I am still getting an INVALID error. I will continue to poke around but if you can assist, just let me know what you find out.

[Jeff_Mash]

From what I can see, when you submit the form, the following variable is empty:

$_POST[$_SESSION['captcha_field']]

Now to figure out how to make sure the value gets saved in there!

Nevermind my last post. The captcha_test page won't validate the code correctly, and I was trying to figure out why.

However, the real script on the Contact Us page now works. So in order to get around the Enable This Picture error that you see when using the Ultimate SEO module, simply do that little code change below and it will display the picture for you.

Hope that helps!

Open the includes/classes/captcha.php and change the following:

FIND in function captcha():

$this->img_href = zen_href_link('captcha_img.php', zen_session_name() . '=' . zen_session_id(), 'SSL', false, false, true);

REPLACE WITH:

$this->img_href = original_zen_href_link('captcha_img.php', zen_session_name() . '=' . zen_session_id(), 'SSL', false, false, true);

Open the includes/classes/captcha.php and change the following:

Jeff.. tried the code change and got a white screen....

I've tested on my heavy modified site, I use USEO. Also tested on a fresh install with no modes or .htaccess .. all 1.3.8a I get the same results on my testing server.

I found if I comment out a line in includes/init_includes/init_customer_auth.php
line;

zen_redirect(zen_href_link(FILENAME_LOGIN, '', 'SSL'));

CAPTCHA shows and works, but I don't think that would be a good idea for a live site. I don't have a SSL cert installed on my testing server, so I'm still looking at the code. For now, I don't think USEO or .htaccess is the problem, but more of an SSL thing. Least that's how it's behaving on my system.

Okay after some retesting and and doing some odd ball reconfigurations if you are using the captcha-number-subject-combo-in-one-1.0 here is a way to test your mod install by doing the following to make sure it is not folder over ride related.

Before doing so be sure to back up the original files no matter the issue and you will have a backup of the original and can replace any problems with it.

Some of you are using this mod with Ultimate SEO however the pages that the captcha work on are not to be used in SEO unless this is a necessary must and it is not recommended to use with the following pages if you have it configured this way.

Pages Are:

1. Create Account Page
2. Leave A Review Page
3. Tell A Friend Page
4. Login Page
5. Contact Us Page
6. Link Submit - Only if your using this

These pages are not recommended for rank or search engines not sure why you would even use these pages for rank or any other search engine related tasks.

If you have your htaccess file configured to rewrite them simply rewrite the htaccess file to ignore friendly url on the pages above.

Also for the ones with SSL on your live site follow these steps as well so you can find out if your over ride folders are working.

In the mod folders that you downloaded you will see folders name YOUR_TEMPLATE make sure they are renamed to the exact template you are using.

Like in includes/templates/classic if you are using this for your template rename the folders in the mod folders from YOUR_TEMPLATE to classic. if you think you done so double check to be absolute sure they are named same as your template folder.

If you do not know which template you are using then go to the zencart
admin --> templates, this will tell you which template you are using.

Now since you have checked and made sure which template you have named all folders correctly and it still does not work do the following and test it this way.

Instead of the over ride folders replace the original files instead of using the over ride folder.

Here is how you do that.

1. In your ftp go to all folders that you see in the mod folder

For example the includes/modules/YOUR_TEMPLATE just like it is in the downloaded file you got from the download sections of zencart.

Now instead of using the override replace the file in the main modules folder create_account.php and do all files this way and then test your store.

It has been reported to us that sometimes this mod does not work in the over rides reason is unknown and is still under development. Until this you can test this on a test site and not a LIVE site and see if it works.

here is a 100% live site we just installed this mod on and nothing was done to it, it is the same exact file set you are using.

https://www.echo-electronics.com

This site is using both Ultimate SEO and SSL at the same time and it works fine.

Do the above tests and see how it works for you. If it works after testing with the core files instead of the over ride folder then you know one of the few things listed.

1. Another mod is conflicting if any installed.
2. Your over ride setup is not complete in some way
3. Your htaccess rewrite is not written or coded correctly
4. Just forgot something?

The site I posted shows this mod is in 100% working order and the problem should go away after you tried everything above.

As for shared ssl this should work as well but we have no means of testing shared ssl as we do not use shared for security reasons.

We wish you luck.

Thanks Andrew for the Mod, and everyone for the help with debugging and documentation.

I installed this and it works perfectly with just one small exception. I use css buttons, and the redraw image button is not active. The user can not click on it to generate an action, it simply selects the ALT text.

Does anyone have a suggestion for a fix? Either making the CSS button work, or disabling it for this single use?

[ts232]

I am thinking a fix could be in the classes/captcha.php function:

function redraw_button($image, $alt = '', $parameters = '', $sec_class = '') {
    $redraw = 'onclick="document.getElementById(\'captcha-img\').src=\'' . $this->img_href . '&rand=\'+Math.random();return false;"';
    return zen_image_button($image, $alt, $redraw . ' ' . $parameters, $sec_class );
}
