Untuk dapat membuat halaman login harus terlebih dahulu tersambung atau connect dengan database yang telah dibuat.  Database  yang telah dibuat dapat disambungkan dengan cara membuat file global.php. Folder-folder web .  global.php <?php $conn = mysqli_connect ( "localhost" , "root" , "" , "databasename" ); Diperlukan sebuah logika atau function untuk bisa melakukan login, maka dibuat lah file dengan nama function.php. Pada folder ini juga harus memanggil terlebih dahulu file global.php.  <?php include "global.php"; function.php function query ( $query ) {     global $conn ;     $result = mysqli_query ( $conn , $query );     $rows = [];     while ( $row = mysqli_fetch_assoc ( $result ) ) {         $rows [] = $row ;     }     return $rows ; } function insert ( $data ) {     global $conn ;     $nama_produk = htmlspecialchars ( $data [ "nama_produk" ]); ...
