The captcha does not show.

Output:
Array
(
[code] => 49cTm
[image_src] => /hp-captcha.php?_CAPTCHA&t=0.39992300+1464080100
)
Even when I change the file simple-php-captcha.php to force the proper output, the image won't load, so I guess there is another problem.

Please help

my path is /media/mvm/Home/Dropbox/Privat/Programming/PHP/site.com/www/vendor/simple-php-captcha-master

but $image_src becomes /e/Dropbox/Privat/Programming/PHP/site.com/www/vendor/simple-php-captcha-master/simple-php-captcha.php

So basically the captcha works on local wamp server. But when i put it on my ftp (i put all files in same folder, like in local). The image refuses to show up.

I did this to check something : "echo $_SESSION['captcha']['image_src'];"

and i get : /aptcha.php?_CAPTCHA&t=0.80883100+1340844566

So i thought that i should put manually " /captcha.php?_CAPTCHA&t=0.80883100+1340844566" in the $image_src variable.....but it didn't work. Can you please help.

Thanks in advance !

Can you add a composer.json and/or add your package to packagist?
Then your package can be installed via the package manager composer.

Currently this is not possible, even not when adding you library to composer via repositories reference, because it can not find a composer.json file in your repository.

The simple-php-captcha.php file has a vulnerability enabling a client to generate the captcha response automatically, effectively bypassing the captcha.

Since microtime() is used both in the initial seed for the captcha and in the captcha url path sent to the client, it is possible to generate the captcha result automatically by running the same code client-side.

I can share a proof of concept privately if you need it. Just let me know how to reach you.

This was a fun project while it lasted, but I no longer have time to commit to maintaining it. If you're up for adopting it, please let me know below.

Working on pc perfect, but on mobile, there is no image. Is this happening just to me?

I'm having an issue. The image isn't showing up and when I view the image URL I get this error:

_Notice: Undefined index: CAPTCHA in /Applications/MAMP/htdocs/gifsite/plugins/captcha/simple-php-captcha.php on line 113

Not sure what's going on here, but it looks like it's something wrong with the code for simple-php-captcha.

Thanks,
Nathan

I can see captcha image but i want to verify the captcha in send_mail.php.

if($_SESSION['captcha']['code'] === $captcha) { echo "Massage was sent."; } else { echo "Mailer Error: " . $mail->ErrorInfo; exit; }

I couldn't run it.

Hi.
It seems that captcha create wrong image :

the text is result of : echo $_SESSION['captcha']['code']; and its different from the created photo by captcha.

To fix just add this two lines ~ line 115

    imagealphablending($captcha, true); // setting alpha blending on
    imagesavealpha($captcha , true); // save alphablending setting (important)

Sorry if this isn't the right way to do this. I'm new to GitHub :)

There is a problem in Opera browser.

Image isn't loaded often there.

Good script! I just wanna know how to refresh the CAPTCHA when I click the image? Thanks!

Im trying to load the image on ajax. The image is not loading and when I checked the log its showing as PHP Notice: Undefined index: _CAPTCHA
Please help me out.

The image doesn't load the first time the script is run, however it will load fine if the page is reloaded or if you browse away from the page and then return to it. Any help would be appreciated, please email me direct as [email protected]. Thanks.

Somone have an idea ?

Best regards,

On the project page: https://github.com/claviska/simple-php-captcha

The link to the demo is http://labs.abeautifulsite.dev/simple-php-captcha/ when it should be http://labs.abeautifulsite.net/simple-php-captcha/.

I have been using the captcha for a while now with no itch, but later I discovered that it doesn't work well on mobile phones it disappears after a few seconds of page load but works well on the desktop .
How do I go about this?

Hi there, I had this script working perfectly on two sites and suddenly today I noticed that both are just showing a missing image. Here is the link to one: http://forum-ids.org/contact/.

Do you have any idea why this might have happened? Your help is greatly appreciated!

Warmest regards,
Kate

If you submit something then hit the "back button", the same captcha is available.

I just coded this for cakePHP.

Is this OK for the license ?
Should you link back ?
Do you want ownership of the cakePHP version ?
