The path is incorrect, please refer to: http://www.zhao.demo/index.php/admins/Home/logincheck
Look at the URL of the page showing 404
There are two pages that may jump to this page
1. Click login and jumphttp://XXX/logincheck.php
2. Click to register and jump to http://XXX/register.php
It’s in the same directory.
It should be that the path is wrong. If your html and php files are in the same directory, it will be fine if you write this way. If they are not in the same directory, there will be a problem.
<form action="logincheck.php" method="post">
It should be the wrong path: action="/logincheck.php" or action="./logincheck.php"
