hi @Alex Lancer,
in your Route.php :
$routes->get('/', 'Users::index');
this is not work for me, I change to :
$routes->match(['get', 'post'], '/', 'Users::index')
and it's works for me.
Is that right ?
Please comment, thank you.

Hey Alex! Great tutorial so far. I am having an issue at 11:05 where I am presented with a "The email field is required.
The password field is required." instead of "Email or password don't match". I continued through and added the password_verify line to UserRules.php but I am still presented with "The email field is required.
The password field is required." even though they are both supplied and correct. Any suggestions?

Alex - Great tutorial! 
I have a problem with picking up the custom css for the error messages on Login/Registration forms. I am adding the following to the head section (right under the bootstrap link) of Views/templates/header.php file: <link rel="stylesheet" there is a file by that name in that location, but I can't seem to access the styles. Any thoughts?

Hi Alex, I discovered something interesting. In your video you outputted errors to view by using $data['validation'] = $this->validator; that way the whole validation object gets passed to view with all the rules and stuff. It might be much leaner by passing just the error array by doing $data['errors'] = Then In the view you can traverse through $errors array of key value pairs.

Hi alex, every time I try to log in with credential right or wrong I get the message 404 and it tells me that "Can't find route for 'post: /.' I checked your code in github and it was exactly the same, do you know why tjis happens?

[aqsalardiana]

i already followed your tutorial, but everytime i clicked that login button, it enters anyway even with random data (random username and password)

[dengannama]

Hi Alex, Thank you for giving this very useful tutorial. but I found a problem with validateUser[email, password] which shows a mismatch. is this a problem with UserModel or UserRules? even though I've often compared your code.

[sivasankari]

hi sir, i followed your tutorial. how do you set default localhost in codeigniter? i am using like this localhost:8080/users because of its i cannot redirect to next page after submit. it send next page like localhost/users

[coleenjaemoralidad]

help! i have an error "Call to undefined function set_value() " everytime I login.

[Xvqier]

Hi Alex, I see you face an error on the line 33 because of the $model->model() whereas it should be $model->where() which I am not sure why did you only get the error now and not when you test the login function earlier. I should have just continued watching the whole video instead of spending 2 days to debug that issue. After I fixed it then I realized you had that error. omg

[sebastianramirez]

Hi Alex, When I put the data correctly to login, I keep getting the validation error(Email or Password don't match).

[AntonioVillordo]

Excelente Axel... la libreria Shopping Cart, no esta disponible en esta version? Sabes si existe alguna posibilidad de integrarla? Gracias

[mrandmrsbhatia]

Hi Thanks for great video but password verify function not returning anything..its always says that not match...am stuck here please help

[sandeepkumarr]

a great thank you to you for this help

[itsRekx]

I was wondering and a little bit confused, you use CodeIgniter/Model in the model file but don't use CodeIgniter/Controller in the controller file. So what's the difference if using CodeIgniter/Controller instead to not using it? isn't that important?

[siddheshkadam]

Hey hie Alex, I just want to validate session for all controllers. How can I do with CI4?
Plz guide

Hi! First, I want to thank you for what are you doing on your channel. It helps me, but now I have a problem with validateUser method, even if the password is correct, the form is not valid because the password and email don't mach. Can you please provide me a solution? Thank you in advance!

[prithvituladhar]

validateUser function has error which allows incorrect password to is no else statement of " if(!$user) ".
