php login form not working correctly - php

Question

I'm trying to create a simple login functionality but it's not working, and I'm relatively new to mysqli so please bear with me. I just want to check if the email address and password are correct and if they are then log the user in. Thanks in advance.
Here is my login code that checks the credentials:
UPDATED CODE - I added the report all and I'm now getting internal server error
<?php
require_once 'connect.php';
mysqli_report(MYSQLI_REPORT_ALL);
session_start();
if (!isset($_SESSION['email'])) {
$e = trim($_REQUEST['email']);
$email = $mysqli->real_escape_string($e);
$p = trim($_REQUEST['password']);
$password = $mysqli->real_escape_string($p);
/*
if ($result = $mysqli->query("SELECT email, password, user_id" .
" FROM users" .
" WHERE email = '$email' AND password = '$password'")) {
printf("Select returned %d rows.\n", $result->num_rows);
echo 'Total results: ' . $result->num_rows;
}
*/
if ($stmt = $mysqli->prepare("SELECT email, password, user_id FROM users WHERE email=? AND password=?")) {
/* bind parameters for markers */
$stmt->bind_param("ss", $email, $password);
/* execute query */
$stmt->execute();
/* bind result variables */
$stmt->bind_result($email, $password);
/* fetch value */
$stmt->fetch();
if ($stmt->num_rows==1) {
$row = $stmt->fetch_assoc(MYSQLI_NUM);
$user_id = $row['user_id'];
$_SESSION['user_id'] = $user_id;
$_SESSION['email'] = $email;
header("Location: home.php");
/* close statement */
$stmt->close();
} else {
printf("Error message: %s\n", $mysqli->error);
}
/*
if ($result->num_rows==1) {
$row = $result->fetch_assoc(MYSQLI_NUM);
$user_id = $row['user_id'];
if ($query_group = $mysqli->query("SELECT *" .
" FROM user_groups" .
" WHERE user_id = '".$user_id."'")) {
//No more setcookie
$_SESSION['user_id'] = $user_id;
$_SESSION['email'] = $email;
} else {
echo 'Did not work';
}
}
*/
/* free result set */
// $result->close();
}
}
?>
And here is connect.php to connect to the database:
<?php
$mysqli = new mysqli("data", "username", "password", "db");
if($mysqli->connect_errno > 0){
die('Unable to connect to database [' . $mysqli->connect_error . ']');
}
?>

Answer 1

did you try to remove one of the brackets in the end of ypur code. I guess you have to remove one of them.
