"Login" control error page

[semua]

Hello, I added a "Login" control and entered the MySQL table data. I registered a user in the database and everything ok, however when I log in the page is always redirected to "Error Page". I have already tried to change the "usarname" and "password" in the database but not later. What could be happening?

Usually this behavior is related to problems with PHP sessions on the server side.

Are you sure the user is in the database?
Are there any error in the server PHP log?

Hello
I can not find any mistakes. And the password is correct. Follow the link https://bit.ly/2OOwOeb. Test Login: 1, Test Password: 1. Please try.

Did you try with a normal username like user1, password1?

I have tried to change the user and the password, I have tried to delete and add new users and it does not work, it always returns the same problem. And where can I see the server log (use HostGator)?

You will need to ask your webhost about this.

I figured out what the problem is. Php uses md5 to load the password:

Code: Select all

$crypt_pass = md5($_POST['password']);

only that my password in the database is not encrypted, then the database password is compared with the password of the textbox, but as one is encrypted and another does not result in false.

I removed the md5 and it works perfectly:

Code: Select all

$crypt_pass = $_POST['password'];

But the question now is: is it safe to leave without the md5? And if it is not, how do I create a password using md5 to save to the database?

It is safer to use md5.
