Answer 1

I watched the video from the beginning today and checked step by step. It turned out that there was a mistake here

$rule = [
'username|username' => 'require',
'password|password' => 'require ',
'verify|Verification code' => 'require|captcha'
];

The template I downloaded is here

<input id="" name="username" type="text" placeholder=" Account" class="input-text size-L">

The name attribute here is 'username', and the attribute value in the teacher's template is 'name'. After changing it, there will be no other problems

Answer 2

There are many problems with the courseware in this section

There is nothing in constructing the query conditions and it is still in a place where the verification code cannot be empty

Answer 3

The value of the username was not received. Can you dump the received post data?

Answer 4

This is the same problem
