adam291086 Posted November 6, 2007 Share Posted November 6, 2007 Hello. I have a very simple CMS that allows the users to upload, edit and delete page content. All these function are in an admin section which has a authentication part using Cookies. The question is do i need to add in validation checks on the information being sent to prevent people dumping my whole database. This is becase only trusted users will be using the site. My gut feeling is going to be yes just in case but i have no idea how to do this, any push in the right direction is much appreciated.

revraz Posted November 6, 2007 Share Posted November 6, 2007 Anytime any data is entered into your database, you need to validate it for the type of data you are expecting. It doesn't have to be malicious to be bad, it can be just the wrong type of data as well. Garbage in, garbage out.

revraz Posted November 6, 2007 Share Posted November 6, 2007 What if one of your trusted users gets a keylogging virus and then someone gains access to your site? Regardless of if you'd get hacked or not, don't put yourself in a spot where your database can either get xss attacks or just bad data. Get in the habit of doing it right the first time so you don't have to go back later and fix it all.

adam291086 Posted November 6, 2007 Author Share Posted November 6, 2007 ok so i will go with my gut feeling of yes. Is there any tutorial about this? Link to comment https://forums.phpfreaks.com/topic/76233-solved-question/#findComment-385849 Share on other sites More sharing options...
revraz Posted November 6, 2007 Share Posted November 6, 2007 Search on these PHP/MySQL keywords: mysql_real_escape_string stripslashes trim You'll also want to validate for correct data type like INT, NOT NULL or EMPTY, length of the data if there a mins/max sizes, etc. Link to comment https://forums.phpfreaks.com/topic/76233-solved-question/#findComment-385872 Share on other sites More sharing options...
