mysql_real_escape_string()

oh yeah, i know what you are talking about,

you can actually configure your server to add slashes to your data whenever an apastrophi is entered, so when a user enters any apostrophi into the form and then you enter it with a query, you need to ad a slah.

for example:
$string = wallpaper's are cool at wallpaperama

the way you need to enter that is with:
$string = wallpaper\'s are cool at wallpaperama

but you cant do that manually right. well, the fine folks at php.net gave us a solution.

use the mysql_real_escape_string($string) function

so declare your textarea string with the mysql_real_escape_string function, like this:

$string = mysql_real_escape_string($string)

hope that helps
