bbPress.org

ok i will share.

Ya ok i got something figured out. its very basic but you can easily add to this. here’s the code

This basically ads a field call ‘lp_post_honey_post’ with the question “I am a robot”. if the user answers anything other than ‘no’ the post craps out with an error. currently the error message is that the post parameters are wrong, but maybe if somebody can tell me how to set the bbpress error message I can fix that.

You can see the filter in action here

There are a few tweaks you could make to this. if you have a plugin like piklist you can easily have a settings page where you could set both the question and the answer. And of course you can change the question in the hard code.

I choose the wp_insert_post_empty_content filter because it fires early on in the wp_update_post routine, saving some CPU cycles.

If somebody wants to help me set this up as a wordpress plugin we could make this a plugin pretty easily. I’m guessing there would be a lot of interest in this.
incorrect code removed ! - correct version below

it will work now

Ah you’ll have to do that again. the code above has a line commented out that shouldn’t be. sorry for the hassle

add_action('bbp_theme_after_topic_form_content','lp_add_honeypot');
add_action('bbp_theme_after_reply_form_content','lp_add_honeypot');
function lp_add_honeypot() {

    if (is_user_logged_in())
        return;
    ?>
<p>
    <label for="lp_post_honey_pot">I am a robot (yes/no)</label><br />
    <input type="text" value="" tabindex="103" size="40" name="lp_post_honey_pot" id="lp_post_honey_pot"  />
</p>
<?php     
}

add_filter('wp_insert_post_empty_content', 'lp_check_honeypot', 10, 2);
function lp_check_honeypot($is_empty, $postarr) {
    
     if (is_user_logged_in())
        return false;
    

    if ($postarr['post_type'] == 'topic' || $postarr['post_type'] == 'reply') {//only do this for bbspress
        if ($postarr['bbp_post_as_submitted']['POST_lp_post_honey_pot'] == 'no') {
            return false; //treat this post as good
        }

        return true;
    }
    return false;
}

I only need this to work for users who are not logged in, guests, so i’ve added a couple of lines to turn this off when users are logged in. if you want to test even registered users just leave those lines in.

When I have a bit of time I’ll look into bbpress errors and find a way to set an appropriate error message.

Have fun and let us know if you use it and it works for you or not
