New Social Network - Part 4 - Logging in Users

In this video we'll be doing the login validation to check each users details before they login.

This means that users will only be able to login using the correct details, once they provide the correct details we'll be able to create a login token to securely check if the user is logged in on each page they visit.

i have added the same source code, still whenever I login with the correct password it shows the invalid
Please help...

Saying that only password is incorrect is not a good idea (for obvious reason). It is better to say that username or password is incorrect.

I am using the exact same code on github, but I get this error :
Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '0' for key 'PRIMARY'' in Stack trace: #0 PDOStatement->execute(Array) #1 DB::query('INSERT INTO use...', Array) #2 {main} thrown in on line 10

Please tell me how to fix Incorrect Password Issue :(

[MilesRoseProductions]

I figured out a way to solve the incorrect passwords bug that a lot of people seem to be having. it seems that the password column in the users table needs to have a VARCHAR that is longer than 60 in order to fit the hash'd password. I changed my password VARCHAR to 1000 with this MySql command:

ALTER TABLE users MODIFY password VARCHAR(1000);

After I modified the table, every user I created after that seems to be able to login just fine.

If your code has invalid password check the database if the login details are under the right field, I inserted password into email field and almost ran mad for over 2hrs debugging

If i want to create the login form inside my index file i just copy the php soce from the login file to the index?

[namahshrestha]

Hey man just a quick question. How come you gotta use [0]['password'] after already specifying in the query that you want password where username = :username. Won't the query itself only return a single value?

[erlendbanken]

The passwords and email are stored in the wrong places in the database, how do I fix this?
