When you insert or upate a password in a MySQL table, you can use MySQL's PASSWORD() function by issuing a query like the following. Assume that the new username is "foo" and the new password is "bar", and user credentials are stored in a table called "credentials":
INSERT INTO credentials (username, userpassword) VALUES ('foo', password('bar'))
When you want to verify a set of credentials later handed to your script by a user, issue a command similar to:
SELECT COUNT(username) FROM credentials WHERE username = '<user-provided username>' AND userpassword = PASSWORD('<user-provided password>')
If it finds a set of credentials that match the credentials provided by your user, the last query should return 1. Otherwise it will return 0. Want the best answers? Ask the best questions: TANSTAAFL!
