Decided not to insert my query...

[Hitman]

It was working until I added the date; I removed it and it still didn't work. The config.php is fine and it can connect. However NOTHING is being inserted into the db!

What's wrong!?

        $string = NULL;
   
        for($i = 0; $i <= 7; $i++) {
   
            $string .= $chars[rand(0,strlen($chars)-1)];
      
        }

        return $string;
        
}  
$salt = generate_random_string();

I don't get any php errors, what's wrong?

Try that.

Thanks very much it works!

How come it wasn't working with clean($_post['whatever'])

[lolwut]

Because the clean function doesn't exist? Assuming that because it isn't in the code.
CleanUp function which you need to add to your page AFTER the SQL connection, because of the way mysql_real_escape_string() works :

function CleanUp($vari){
strip_tags($vari);
stripslashes($vari);
mysql_real_escape_string($vari);
return $vari;
}

It was nothing to do with the clean(); function, I just simply looked to reduce the amount of code. The only problem was in the SQL Query you simply ommited a ) at the end of the values bit.

It's in config.php which is included on every page.

So the code Splinter gave me is ok?
