BAD WORD IS TEXT OR TEXT FIELD, FIND AND STOP

[Orionsbelter]

Ok, i find many users sign up with words like fuck and shit in thier name and sometime they send messages to each other swearing at one another i do replace the swears in the messages but how ever would like to have something that will stop them

 

example

 

if($_POST['username'] contains('fuck')){ echo"badword used";}

 

is there anything like that?

Simple script to start with

 

$wordlist = array of swear words;

foreach ($wordlist as $word) {

Do eregi_replace() on $word;

}

That will replace the word.

To find words you can use a variety of string functions. You will need a bad words list to compare as the post above suggests.

 

strstr()

preg_match()

strstr()

ereg()

preg_match_all()

[mtoynbee]

$wordlist = array("poop","ass");
foreach ($wordlist as $word) {

if (eregi($bad_word,$string))
{
exit("no swearing please");
}
}

Check your code mtoynbee. $bad_word variable is undefined in eregi function. You have defined $word in the foreach loop.

Down with censorship!

You will never be able to filter it all, all you'll do is make them more creative.

Yep saw that error. Sorry - it was only a quick and dirty example.

There was a rather involved thread on this here: http://www.phpfreaks.com/forums/index.php/topic,225600.0.html

anymore?

I have a massive word list if you want it i can email it as the word filters here will prevent it from being visible.

 

Also i use str_ireplace();

and have an array of bad words.
