It is worth nothing that this is an incredibly insecure way to handle logins. The correct way to do this is by using a cryptographic hash to store the salted password in the database.

Thus, if your database is compromised, you will not leak passwords for all of your users as so many companies have done recently.

This is especially important as users may reuse these passwords on much more important and secure sites. The correct way is: Now, when someone attempts a login, you would take what they supply for their password, append the stored salt, hash it, and compare that to the stored hash in your database.

To anyone writing a tutorial, I implore you to please stop spreading dangerous and irresponsible practices.

You have a duty to your users to have at least a modicum of understanding of security for their sake. Hey, great page and worked first time and was very easy to understand.

Check whether your query is executed properly or does it contains anything or not. The problem may be with the connection, query or it may be with the tables.

So, make sure that your query must contain the same table name that you have created in your database. Also, check that the query contains the results.

Use the same database name, table name and column name in query that you have created at your end. It would resolve your issue. How to check with session which user is logged in …?
