<?php
// include mysql database configuration file
include_once 'db.php';
if (isset($_POST['submit']))
{
    // Allowed mime types
    $fileMimes = array(
        'text/x-comma-separated-values',
        'text/comma-separated-values',
        'application/octet-stream',
        'application/vnd.ms-excel',
        'application/x-csv',
        'text/x-csv',
        'text/csv',
        'application/csv',
        'application/excel',
        'application/vnd.msexcel',
        'text/plain'
    );
    // Validate whether selected file is a CSV file
    if (!empty($_FILES['file']['name']) && in_array($_FILES['file']['type'], $fileMimes))
    {
            // Open uploaded CSV file with read-only mode
            $csvFile = fopen($_FILES['file']['tmp_name'], 'r');
            // Skip the first line
            fgetcsv($csvFile);
            // Parse data from CSV file line by line
             // Parse data from CSV file line by line
            while (($getData = fgetcsv($csvFile, 10000, ",")) !== FALSE)
            {
                // Get row data
                $name = $getData[0];
                $email = $getData[1];
                $phone = $getData[2];
                $status = $getData[3];
                // If user already exists in the database with the same email
                $query = "SELECT id FROM users WHERE email = '" . $getData[1] . "'";
                $check = mysqli_query($conn, $query);
                if ($check->num_rows > 0)
                {
                    mysqli_query($conn, "UPDATE users SET name = '" . $name . "', phone = '" . $phone . "', status = '" . $status . "', created_at = NOW() WHERE email = '" . $email . "'");
                }
                else
                {
                     mysqli_query($conn, "INSERT INTO users (name, email, phone, created_at, updated_at, status) VALUES ('" . $name . "', '" . $email . "', '" . $phone . "', NOW(), NOW(), '" . $status . "')");
                }
            }
            // Close opened CSV file
            fclose($csvFile);
            header("Location: index.php");
        
    }
