<?php

$is_invalid = false;

if ($_SERVER["REQUEST_METHOD"] === "POST") {
    
    $mysqli = require __DIR__ . "/database.php";
    
    $sql = sprintf("SELECT * FROM user
                    WHERE email = '%s'",
                   $mysqli->real_escape_string($_POST["email"]));
    
    $result = $mysqli->query($sql);
    
    $user = $result->fetch_assoc();
    
    if ($user) {
        
        if (password_verify($_POST["password"], $user["password_hash"])) {

            
            session_start();
            
            session_regenerate_id();
            
            $_SESSION["user_id"] = $user["id"];
            
            header("Location: index.php");
            exit;
        }
    }
    
    $is_invalid = true;
}

?>

Read the error message, it couldn't be any clearer:

Error

Unknown column 'email' in 'where clause'

You are requesting all columns from the user table, and trying to restrict it to specific values of the email column.
But ... there is no column in the user table called email.

We can't fix that - we don't have access to your DB to see what columns you do have!

You're welcome!

Just so you know in future ... don't post comments like this as solutions - if you use the "Have a Question or Comment?" button instead, then an email is sent to the person you are talking to (just as this sent one to you). If you post as a solution, the only person who could get a notification is you!
