phprocker Posted November 8, 2010 Share Posted November 8, 2010 Is it necessary to use mysql_real_escape_string() when I'm retrieving fields from a table that the user had no input on the result? Such as if there was a template color that the admin set in the siteconfig table that the script selects automatically with no user input. Cheers!

phprocker Posted November 8, 2010 Author Share Posted November 8, 2010 It is designed to sanitize data going into the database. Couldn't there be an SQL injectionwhen there is any call to the database such as a SELECT from the table?

trq Posted November 8, 2010 Share Posted November 8, 2010 It is designed to sanitize data going into the database. Not exactly. Couldn't there be an SQL injectionwhen there is any call to the database such as a SELECT from the table? Yes. mysql_real_escape_string should be used on ANY and ALL user inputted data that is to be used within a query (of ANY and ALL types).

phprocker Posted November 8, 2010 Author Share Posted November 8, 2010 Thorpe thank you for the answer. Now what about my first question though. Is it necessary to use it for non-user-input database queries such as a config selection from a config table.

trq Posted November 8, 2010 Share Posted November 8, 2010 I believe that is covered in my last post. The answer is no. hard coded queries are not effected.
