[Mediawiki-l] escaping user input

[Paul Jones]

I am creating a custom special page to gather some information from user. I 
have create a table to store the data in and am trying to use the Database 
object to access it. This all works fine, but I need to validate the user 
input. I would like to use mysql_real_escape_string to avoid sql injection, 
but there does not seem to be any function in the Database object to escape 
a string. I suspect there is an easy way to do this since mediawiki accepts 
a lot of user input. Anyone know what the best way to go about escaping user 
input is within the mediawiki architecture?

Thank you,
Paul
