在使用MySQL数据库检查脚本时，错误的电子邮件或密码错误

When I try to check my login working it shows me this => email and password incorrect. I have entered the same email and password but it's not working fine.

I'm making a login registration form but it's not working properly when I got to the login form

Regestration.php

<?php
session_start();

if(isset($_SESSION['usr_id'])) {
  header("Location: index.php");
}

include_once 'db/connect_db.php';

//set validation error flag as false
$error = false;

//check if form is submitted
if (isset($_POST['signup'])) {
  $name = mysqli_real_escape_string($conn, $_POST['name']);
  $email = mysqli_real_escape_string($conn, $_POST['email']);
  $password = mysqli_real_escape_string($conn, $_POST['password']);
  $cpassword = mysqli_real_escape_string($conn, $_POST['cpassword']);

  //name can contain only alpha characters and space
  if (!preg_match("/^[a-zA-Z ]+$/",$name)) {
    $error = true;
    $name_error = "Name must contain only alphabets and space";
  }
  if(!filter_var($email,FILTER_VALIDATE_EMAIL)) {
    $error = true;
    $email_error = "Please Enter Valid Email ID";
  }
  if(strlen($password) < 6) {
    $error = true;
    $password_error = "Password must be minimum of 6 characters";
  }
  if($password != $cpassword) {
    $error = true;
    $cpassword_error = "Password and Confirm Password doesn't match";
  }
  if (!$error) {
    if(mysqli_query($conn, "INSERT INTO users(name,email,password) VALUES('" . $name . "', '" . $email . "', '" . md5($password) . "')")) {
      $successmsg = "Successfully Registered! <a href='login.php'>Click here to Login</a>";
    } else {
      $errormsg = "Error in registering...Please try again later!";
    }
  }
}
?>

    You never actually attempt to search for the data in "Login.php". Your from action isn't running any PHP code and therefor nothing happens.

    I suggest that you add a database query that searches for the given Username and Password combination and compares it with the input of the user that is attempting to login.
