PHP matcher

Forge

Hey all, I have another PHP question. Im taking the idea from phpBB for "disallow" names. And id like to just have matchs in names. So if i have IamtheShizit And i wanted the word shizit to be disallowed. How would i make it so i can find the words from a database. And use the preg_match() function to "disallow" the name ? Or should i even both with this...

daboss

just use the "like" operator instead of the "=" operator

Python

i think a simple if else statement could be used along with what bimmercenter said

Hmm, CRAZY ENOUGH TO WORK !!! But could you show me the query, this is what i did...
[php]
$query = "SELECT * FROM members_disallow WHERE disallow LIKE $username";
$result = mysql_query($query);
if(mysql_num_rows($result) > 0){
echo "A part of your name is inapropriate, Please change it";
}
else {
[/php]
But i got this error...

Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /home/outpost/public_html/register.php on line 122

This is line 122:

if(mysql_num_rows($result) > 0){

Any ideas?
