I have a family friendly directory but adult, and porn site webmasters keep submiting their dumb sites to my directory. Ok only a few but I don't want them and have to keep rejecting rulebreakers so I want to stop them.

Now my question is how can you make a filter to where if bad words get entered even if mixed with other words the form will not go further.

This is what I have so far but it has to be only the bad word alone submited to be rejected.

if ($ttitle=="$LANG[badword10]") $error.="<LI>".$LANG["bad_words"];

badword10 contains the bad word in the language file.
Also ttitle is the PHP coding Title of my Directory submission. $error displays "Your site is not allowed because your site contains adult/illegal/spam content."

Can anyone tweak this little code to where I can reject any site that uses that word no matter where they put it in a sentance.

Please. I need to keep bad websites from attempting to try to submit them. Who knows they will probably spam me with tons of it and I will take forever to remove it.

just follow the tutorial.
you can also download php filtering classes.

PHP Code:

if (preg_match('!big|brown|fox|jumped|over|the|lazy|dog!i', $site_title)) {
   echo 'u submitted crap u suck kekeke lol';
} 


Next you may put all stop words into array or into a file one per line, implode with | and pass to preg_match() as specified above.

Also I recommend to put Captcha (that image with noise over digits which can be only recognized by human) on your site to prevent automated submissions. Something like PHP Classes - Class: PHP Captcha, though I use the captcha plugin for b2evolution as it perfectly works standalone, google for it.

Ow.. that's a toughie.

There is a very basic way I used to do, is using sub string counts... you know like for instance

PHP Code:

<?

$string = "applebadwordhere";

$exp_check = substr_count($string, 'badword');

if ($exp_check >= 1) { echo "bad word detected!"; } else { echo "OK!"; }

?>

Well you can check it through a while loop within the function for each word - just a thought, there are better ways but i always follow the simpelest methods possible

Thank you it worked. I can finally blocked bad sites. Now that will help me out.

I did better.

I am going to block sites that have bad words in their url, title, and description maybe email.

I can even use the PHP Function to block certain emails, or block spammers email addresses.

This will teach those adult sites a thing or too, and keep them from submiting to my site when it is against the rules, and it is obvious the directory is family friendly but they iqnore it.

Thank You!

Thank you mtishetsky, jito, and vigilphp for your participation.

Oh yeah did you know my site uses the
The iWatchDog™ Program certification. Now my directory will not be accidently blocked by filters
