[TIP] Stop Spam Registration - FINALLY

[darmeth]

Here is a quick, easy, free solution to stop spam registration.

BEFORE: Up to 50 spam user registrations per day
AFTER: 0. Zero. Nada.

PLEASE, IF SOMEONE CAN HELP CONVERT THIS INTO A PLUGIN, THIS WILL BE MOST WELCOME

Tested on 3.5.0 - 3.5.2 with Modern theme.

In oc-include/osclass/frm/Userformclass.php, find this:

Code: [Select]

static public function info_textarea($name, $locale = 'en_US', $value = '') {
            parent::generic_textarea($name . '[' . $locale . ']', $value);
        }
UNDERNEATH IT, ADD:

Code: [Select]

static public function human_check_text($user = null) {
            parent::generic_input_text('humancheck',$value='If you are, please delete all this text',$maxlength='40') ;
        }
In oc-include/osclass/UserActions.php, find this:

Code: [Select]

if($flash_error!='') {
                osc_run_hook('user_register_failed', $error);
                return $flash_error;
            }
UNDERNEATH IT, ADD:

Code: [Select]

if( Params::getParam('humancheck', false, false) !== '') {
                return $flash_error .= _m("Human check must be empty") . PHP_EOL;
                    $error[] = 11;
            }
In Theme/user-register.php, find this:

Code: [Select]

<?php osc_run_hook('user_register_form'); ?>
                        <?php osc_show_recaptcha('register'); ?>
UNDERNEATH IT, ADD:

Code: [Select]

<div class="row">
                            <label for="humancheck"><?php _e('Are you Human?', 'modern') ; ?><em style="color:red"> *</em></label>
                                            <?php UserForm::human_check_text() ; ?>
                        </div>

Hi Darmeth,

I like this simple solution without the need to register recaptcha though it would be nice to make it generic so it can also be used when user's are not logged in and posting comments or contact sellers. I just finished a plugin and it gave me some insights I might use to make this into a small plugin. No promisses or guarantees but I will see what I can do. 

If I have something working I would like you to help me testing it before putting it up for all.

Regards,
Eric

OKAY, got something but I am STUCK! 

So I thought let's see if there's a bright young man here that can help us out figuring out how to add validation.
The code below is the actual plugin so far, if you save the code into 'index.php' and put it in a folder called 'ruHuman' and then zip it you can actually add this as a plugin in your admin menu. BUT, it only ads the input field and the most important part, the validation / action is missing so it's pretty much useless the way it is right now. Any help is appreciated....

(I thought about adding javascript, extending the class it concerns but .... stuck, maybe it is not possible?)

Code: [Select]

Hi,

This seems to work for me:

Code: [Select]

<?php
function ruHumanCheck() { 

    if(Params::getParam('humancheck') != '') { // Text hasn't been deleted
        osc_add_flash_error_message('Get out, you nasty robot!');
        osc_redirect_to( osc_item_post_url()) ;        
    }
}

osc_add_hook('pre_item_add', 'ruHumanCheck');
?>

Hi teseo,

thanks for looking along, your code is meant for item publish

Here's my current index.php code, it MIGHT work, haven't tested it yet.

Hi SmaRTey,

replace the hook

Code: [Select]

osc_add_hook('pre_item_add', 'ruHumanCheck');

with

Code: [Select]

osc_add_hook('before_user_register', 'ruHumanCheck');

and it should work.

Regards

[SmaRTeY]

Okay, thanks again, will check it tomorrow....noticed I used the 'old' hook which was mentioned in the forums.


Best Regards,
Eric

[teseo]

Sorry, I didn't realize you were operating over users, @dev101's is the equivalent to mine for items. Anyway, here's a good mechanism for server side validation of any form field. 

Regards

[SmaRTeY]

It works! 

Guys.... thanks for helping out!
Nice there's another small plugin that is not only pretty easy to understand also gives more insight to others...I hope!

So, Darmeth, here's what you wished for, hope it will tickle you (and others) into making plugins as well 


Regards,
Eric

[SmaRTeY]

I am analysing how to expand this plugin so it can also be used in item-contact, item-post, item-comment and maybe other parts of Osclass. Item-contact I have working now as well so on to the next....

I know there are at least 3 plugins available (sweet captcha / recaptcha en math plugin (paid)) but both the sweet and recaptcha depend on 3rd parties and there is no other free captcha plugin as far as I know.

Anybody else interested in this? 


Regards,
Eric

[maakuone]

frosticek - that one is paid

[frosticek]

@maakuone
I though you are considering also paid solutions

I know there are at least 3 plugins available (sweet captcha / recaptcha en math plugin (paid)) but both ...

If you consider hours of work to making such solution 100% working, you will see you lost much more. I prefer looking for different solutions that those already existing.

[SmaRTeY]

Hi,

I am much in favor of Open Source Frosticek that is why I am asking here as well as spending time in 'learning' Osclass and helping others in understanding Osclass better hoping they will also contribute Open Source in return 

I do not like the dependancies in my website and I do not want to pay for a plugin I can create myself.
Also I am not trying to create a 100% Anti Spam solution, just a simple captcha like the paid math captcha but open source and free...

In the mean time I am also looking into the osclass_pm plugin from Trains, I have nearly finished all I want for having a good working messaging plugin that fits the theme I bought. I will share it for free with the theme creator hoping ALL themes will have more and better support for the existing plugins so joy for all. Same for the 'offer' plugin from Trains, I found it not to be working 100% but close to so this will be my next personal project....

I will probably also look into a plugin that combines some things from existing plugins... since they are also open source and free I will keep mine free as well. Once I get to that you'll know it in the forums as well 

[frosticek]

@SmaRTeY
Writing your message you got back to my question: ... that fits the theme I bought ...
So, why you would buy something if you can do it by yourself? Because it is lose of time and you can invest that time to more valuable activity, like doing something that is already not.
Why you would do same captcha as is paid math? Again, losing of time.

Anyway, I am big fan of osclass progress and looking for more and more cool plugins, but those that brings something new and are not just copies, paid of free   ... because even you finish your plugin, it does not bring anything new, anything that does not already exists and expand osclass 

[SmaRTeY]

Ha but in this case it would actually be something new.... in a sense that people can use something without the need to pay and have the ability to go without the 3rd party websites 

But I agree, other more interesting plugins are very welcome! (open source of course!)

Eric
