Ok, so i am creating a simple login page for a website as part of the assessment for my course. I have made a simple 'register' form, which can write a username and password to an external .csv form easy enough, but when logging into the website, i do not know how to actually use the data entered into the username and password form, so that it gets checked with the .csv file, so if the details are wrong, an error is thrown. Essentially what i want to do is to read from the .csv file to check the details entered, to either accept the login, or to deny entry. Any help with what code i need would be great.
