Hey all I'm working on a quote script in PHP, it uses SQL. I'm making it in dreamweaver. My question is how would I go about flitering what people can input. For example I was people to NOT be about to post any html tags. Here is the sudo code...

If Quote = *<*>* then
Print = Sorry no HTML tags!
Else
Print Quote to database
End If

I'm not to good with PHP and I have not found time to pick up a book and start to become better at it so if someone could help me out or link me to a place that can tell me how to do this I would be gratefull. Thanks, here is my site http://rhs.zapto.org go to quotes.

Hmm you could always try htmlspecialchars() - it's a string function in PHP that replaces HTML characters like < with codes like &lt;.

To use it:

$inputString = htmlspecialchars($inputString);

then you can just go ahead and add it to your database. If you want to check to see if anything's changed (ie: if there is HTML in the post):

$htmlString = htmlspecialchars($inputString);
if($htmlString != $inputString){
echo "There is HTML in the string";
} else {
echo "There is no HTML in the string";
}

I hope this helps,
Dan
