Database login doesn't seem to be working when password is correct

Database login doesn't seem to be working when password is correct

just wondering if someone can look at this code and tell me where I am
making my mistake. What the code is supposed to do is check username and
password with a database and then run an if statement to either allow the
user to view the page or just show them a "Please login" message. At this
point it is only returning the false values even if the passwords are ==.
I know I can pick up code for this on the internet, but I want to figure
out where my logic (only in my head) is going wrong. I also know I haven't
sanitized the data, but this is just a tutorial for grade 10 students just
learning HTML and CSS with a little bit of PHP. I will get to that
protecting data later. (one concept at a time)
Thanks for the help!
