Chris E. wrote this and I don't understand: I am trying to have it look up these bad words and if it finds one then reprint the page if it doesnt find a word in the list then place in db. I am good until it comes to actually placing it in a page. Can anyone make a real simple form that has me type a message and this function will run? Can anyone please help me? Thanks!

----Sorry Had To Make A New Post------

There are many ways to do this but here's one. You can build a function that checks a variable for bad words and returns false if there are any:

function checkBadWords($text) {
$badWords = array('badword1', 'badword2', 'badword3');
foreach ($badWords as $badWord) {
if (ereg($badWord, $text)) {
return false;
}
}
return true;
}

You can call the funtion in your error checking like this:

if (!checkBadWords($message)) {
// re-print the form
}

So if the function returns false then you want to re-print the form. Otherwise you process it.

Read my previous post... Here is what I formulated. I do however need it to say something if true and just reprint form if false. Here is what I got.
if (!checkBadWords($text)) {
print("<h1>Horrible Word!</h1>");
print("<form method='POST' action='trial.php'>");
print("<p><textarea rows='15' name='text' cols='57'></textarea></p>");
print("<p><input type='submit' value='Submit' name='B1'><input type='reset' value='Reset' name='B2'></p>");
print("</form>");
}
?>
<form method="POST" action="trial.php">
<p><textarea rows="15" name="text" cols="57"></textarea></p>
<p><input type="submit" value="Submit" name="B1"><input type="reset" value="Reset" name="B2"></p>
</form>

Am I even on the right track? I can get it to determine if its a bad word or not, but it reprints the form twice... any way around that? Also how can i make it say "good word" if its true? Thanks!

Thanks dude, I just actually had pre-defined words. I used them and made and used the exit; thing. Thanks!
