QUESTION
I'm currently working on a project and managed to get a working registration and login form. Upon registration, the user is emailed with a 5 character activation code and is asked to insert it on the user profile page in order to change the status from active:0 to active:1 and gains permission to the rest of the site.
For some reason the activation code just simply won't work :/
The following code is the PHP code written to activate the account, I am using PDO queries to connect to the database, but I tried using a mysqli query too but didn't seem to work.
...ANSWER
Answered 2018-Dec-07 at 20:42There are several issues here, from mixing database API's to possible SQL injection, string concatenation issues and incorrect SQL syntax in your UPDATE query.
If you're using PDO for your database connection, you need to remove all references to the oci*
(which are for Oracle databases) and mysqli*
(which is a different API and not compatible with PDO) functions, and use the PDO equivalents.
I will also remove $username
from the queries and use prepared statements instead. $username
may be coming from your own database, but I can't see how it got in there. If you do not have a limit on which characters a username can contain, and the username is properly escaped when it is inserted into your database, then it may contain single (or double) quotes that can still cause trouble in this code. Bottom line: if it was originally user input, it should never be trusted.
