Check your query with database structure. Check if database column of 'req_code' is unique. If it is not unique, it will tempt to update all the records that matched the req_code.

First of all, why are you using two database connection layers in one script; mysql and mysqli. Please, I encorage you to use mysqli since mysql is deprecated.

Also I think you should be precise of the form method you are using so that you don't just use $_GET or $_POST.

But to your question, it seems you are updating the table against a field called req_code. I will advise you to update your database tables using primary keys (usually id's are used as primary keys in the database).

In your example, it can be possible that, that req_code is the same across all fields in the database. But for id's (primary key), it can never be the same.

So if you don't have an id or primary key field, you go ahead and create one and then update your rows where id = userid.
