I am using PHP and MySQL database to do my school project. There is a problem that I encounter when I try to import data in my database. In the 1st table (murid table) it works perfectly, but in the second table (pendaftaran table), it seems to import twice. This is my PHP code. I wonder why my data is inserted twice in the pendaftaran table? <?php session_start(); $username = $_SESSION['username']; $conn = mysqli_connect('localhost','root','','darksith'); if(!$conn) { echo 'Not connected'; } if (isset($_POST['importbutton'])) { $namaFail = $_FILES['file']['tmp_name']; if ($_FILES['file']['size'] > 0) { $fail = fopen($namaFail, 'r'); while (!feof($fail)) { $data = fgetcsv($fail, '0'); $query = "SELECT * FROM murid WHERE No_Sekolah_Murid = '".$data[0]."'"; $result = mysqli_query($conn, $query); if (empty($data[0] || $data[1] || $data[2] || $data[3])) { echo "<script> window.alert('Sila isikan semua medan dalam fail!'); window.location = ''; </script>"; //exit(); } else { if (mysqli_num_rows($result) === 0) { $query1 = "INSERT INTO murid(No_Sekolah_Murid, Nama_Murid, Kelas, Tarikh_Daftar) VALUES('".$data[0]."', '".$data[1]."', '".$data[2]."',NOW())"; $query2 = "INSERT INTO pendaftaran(ID_Pendaftaran, ID_Pengguna, No_Sekolah_Murid, Kod_Pertubuhan) VALUES('', '$username', '".$data[0]."', '".$data[3]."')"; mysqli_query($conn, $query1); var_dump(mysqli_query($conn, $query1)); mysqli_query($conn, $query2); var_dump(mysqli_query($conn, $query2)); // echo "<script> // window.alert('Rekod berjaya ditambahkan!'); // window.location = 'import.html'; // </script>"; } else { "<script> window.alert('Rekod gagal ditambahkan!'); window.location = 'import.html'; </script>"; } } } fclose($fail); } } else { echo "<script> window.alert('Import gagal.
