    Hi, thanks for the tutorial, has helped me a lot even in 2016. I have a question, what if the password value is encrypted in the DB? How do you compare this value with the input on the password textbox? Thanks again

    i love the way you try to copy and paste everything to make it quicker but you just make it slower 😛

    Thank you so much for making this tutorial. I needed to create a login form exactly like this for my college assignment. I tried the code you used in the video and, with a bit of modification to suite my existing code, it worked perfectly. You spoke very clearly and were easy to follow 🙂

    Aren't the magic words for this kind of login something like:
    ' or TRUE
    ?

    Sorry but checking for duplicate logins it's a waste of code, the DB should be taking care of not allowing duplicate usernames; and you are taking too long to explain on a simple code. Also that way of naming variables is a terrible coding practice.

    put this in your password

    ' OR 1=1 — (don't forget the space at the end of the hyphen)

    SQL injection

    I can only sign in with numbers, how do I sign in with letters? The program won't read letters from my database only numbers.

    EDIT: I fixed this. If you insert values into the database manually as letters it won't read them for some reason, watch his next video and setup a registration form.
