tinCaptcha - just another

Postby Replika » Sat May 10, 2008 10:37 am

There are many extenions for captcha, but all I know are bloated. I just want a simple one.
Please have a look at http://joomlacode.org/gf/project/tincaptcha

I found no way to install language with my plugin, so I put it in the component. The plugin file is 120KB, but the most is font files (all fonts are grabbed from dafont.com, and they are copyrighted by their authors).

Here is the Contact page I have intergrated:
Image

And I did:
1. Install both com_tincaptcha and plg_tincaptcha (remember active plugin, we can change some settings in the plugin)
2. In File components\com_contact\controller.php, find and add like this:

Code: Select all

   function submit()
   {
      global $mainframe;

      // Check for request forgeries
      JRequest::checkToken() or jexit( 'Invalid Token' );

      // tincaptcha-
      $captchk = plgSystemTincaptcha::check(JRequest::getVar('captcha', '', 'post'));
      if ($captchk !== true)
      {
         JError::raiseWarning(0, $captchk);
         return false;
      }
      // -tincaptcha


3. In File components\com_contact\views\contact\tmpl\default_form.php, find and add:

Code: Select all

         <label id="contact_textmsg" for="contact_text">
            &nbsp;<?php echo JText::_( 'Enter your message' );?>:
         </label>
         <br />
         <textarea cols="50" rows="10" name="text" id="contact_text" class="inputbox required"></textarea>
         <!-- tincaptcha- -->
         <br />
         <label for="captcha">
            &nbsp;<?php echo JText::_( 'TIN_CAPTCHA' );?>:
         </label>
         <br />
         <input type="text" name="captcha" id="captcha" size="10" class="inputbox required" value="" />
         <br />
            <img src="index.php?option=com_tincaptcha&task=captcha_display" />
         <!-- -tincaptcha -->

That's all.

I do not put $this->display(); after JError::raiseWarning because it just display an empty form.
You might want raiseError instead, it will display only error message

Code: Select all

JError::raiseError(500, $captchk);

What my concern is in J1.5.3, when we typed wrong captcha and go back, all form data are cleared. They can be remembered in J1.5.1 because the code in libraries\joomla\environment\response.php

Code: Select all

//JResponse::setHeader( 'Cache-Control', 'no-store, no-cache, must-revalidate, post-check=0, pre-check=0', false ); // <-- browsers can not remember form
JResponse::setHeader( 'Cache-Control', 'post-check=0, pre-check=0', false ); // <--browsers can with this


I also hack Virtuemart registration form: http://forum.virtuemart.net/index.php?topic=40043.0
For Joomla registration will be available soon. I still want the captcha warning and the form display together with what we've typed in form.

For the refresh image button, change the captcha image tag to this:

Code: Select all

<img src="index.php?option=com_tincaptcha&task=captcha_display" onclick="this.src='index.php?option=com_tincaptcha&task=captcha_display&t='+(new Date()).getTime()" alt="Click to refresh image"/>

or

Code: Select all

<img name="captchaimg" src="index.php?option=com_tincaptcha&task=captcha_display" /><a href="javascript:void(0);" onclick="document.images['captchaimg'].src='index.php?option=com_tincaptcha&task=captcha_display&t='+(new Date()).getTime();return false;">Refresh Image</a>

Installation in my 1.5.3 was easy (thanks). All works well - except I get no error message of any kind when the input doesn't match - just a blank page.

That part of the function *is* triggering, as when I add

Code: Select all

$this->display();
to controller.php I get a new form. I've tried different values in the line

Code: Select all

JError::raiseWarning(500, $captchk);
but nothing works.

Any ideas?

Did you try with default template or not?

Code: Select all

   function submit()
   {
      global $mainframe;

      // Check for request forgeries
      JRequest::checkToken() or jexit( 'Invalid Token' );

      // tincaptcha-
      $captchk = plgSystemTincaptcha::check(JRequest::getVar('captcha', '', 'post'));
      if ($captchk !== true)
      {
         JError::raiseWarning(0, $captchk);
         $this->display();  // <-- display form
         return false;
      }
      // -tincaptcha

Oh my god, easy to use? are you [removed by mod] kidding me?

There's editing and you don't explain which parts of code I should edit, what's the problem with simply attacking ready to replace files and just telling where to put them into ????
Seriously, and even after I edited it and it seemed to work, it only returns a blank page when an error occurs and when I submit the captcha successfully, then it just shows the blank form without any information whether I successfuly sent the message or not.

It's bloody useless, also, the captcha images are way too hard to read, you can't tell whether a "b" is a "6" or when "1" is "l" or "I" just [removed by mod] silly, what's the point of releasing a product with 100 bugs????

:eek: Yep, this is not for a newbie but also not a brain teaser.

it only returns a blank page when an error occurs

Did you read the whole post?

the captcha images are way too hard to read

Just replace the fonts. You should know the principle of the source first or just ask a question.

Maybe the extension is not enough for you but it's good for some people I know and of course, myself.

hi, thanks for your work on this extension. I am using joomla 1.5.3 and have a custom template. I followed the instructions and have enabled the plugin and have inserted the lines of code as you instruct, but when i test my contact form I do not see anything new on it - just the normal form.

Any suggestions? thanks!

Hello,
I very much want to know how to make the font to be shown exactly how it is and not dublicated or other effects like rotated characters and so on.

I also want to know if we can integrate it with Jom Comment.
Thank you

I should change a bit the code to first check user logged in or not, for example:

Code: Select all

$user =& JFactory::getUser();
if (JPluginHelper::isEnabled('system', 'tincaptcha') && $user->get('guest'))
{
      $captchk = plgSystemTincaptcha::check(JRequest::getVar('captcha', '', 'post'));
      if ($captchk !== true)
      {
         JError::raiseWarning(0, $captchk);
         return false;
      }
}


Code: Select all

<?php
$user =& JFactory::getUser();
if (JPluginHelper::isEnabled('system', 'tincaptcha') && $user->get('guest')) :
?>
         <!-- tincaptcha- -->
         <br />
         <label for="captcha">
            &nbsp;<?php echo JText::_( 'TIN_CAPTCHA' );?>:
         </label>
         <br />
         <input type="text" name="captcha" id="captcha" size="10" class="inputbox required" value="" />
         <br />
            <img src="index.php?option=com_tincaptcha&task=captcha_display" />
         <!-- -tincaptcha -->
<?php endif; ?>

First things first, THANK YOU for the time, effort and making this happen as i tried so many with no success and yours worked immediately with Version 1.5.6 :)

Only one small question if i may,

In which file can refresh the image be found so i can add / change the code?

Thanks again 8)

Compare steps in the first post, You can see this line in the hack:

Code: Select all

<img src="index.php?option=com_tincaptcha&task=captcha_display" />


replace to

Code: Select all

<img src="index.php?option=com_tincaptcha&task=captcha_display" onclick="this.src='index.php?option=com_tincaptcha&task=captcha_display&t='+(new Date()).getTime()" alt="<?php echo JText::_('TIN_REFRESH_ALT');?>"/>

or

Code: Select all

<img name="captchaimg" src="index.php?option=com_tincaptcha&task=captcha_display" /><a href="javascript:void(0);" onclick="document.images['captchaimg'].src='index.php?option=com_tincaptcha&task=captcha_display&t='+(new Date()).getTime();return false;"><?php echo JText::_('TIN_REFRESH');?></a>

ok, just tried both codes now, and it does not work. When I click "Refresh image" link the image disapears.


And registered users are still required to input captcha security images.

Worked like a charm in both cases and just for others to know, the first changes the code by clicking ON the image and the other by clicking on the text.

Thanks again and keep up the good job 8)

For contact component is not working, as I posted above. I canţt figure it out, but it seems that I have a problem with captcha images in Jom Comment: images are not rendered first visit of an article...

It works for VM registration!
BUT if I use

Code: Select all

alt="<?php echo JText::_('TIN_REFRESH_ALT'); ?>"
instead of alt="Click to refresh image", it does not work.
Any idea?

Thanks

FOr me the trick to show captcha only to guest is working, but refresh image works only for Virtuemart registration process, using this code

Code: Select all

<img src="index.php?option=com_tincaptcha&task=captcha_display" onclick="this.src=\'index.php?option=com_tincaptcha&task=captcha_display&t=\'+(new Date()).getTime()" alt="Click pentru reincarcare imagine" title="Click to refresh" />


I admit I might have some issues with VM template, but with Joomla? :pop
