<?php

  mysql_connect   ("localhost", "root", "rahasia");
  mysql_select_db ("abms");

      else  {
      
        if (!empty($_FILES['photo']["tmp_name"]))
        {
        
        $namafolder   = "photo/";
        $jenis_gambar = $_FILES['photo']['type'];
        if ($jenis_gambar=="image/jpeg" || $jenis_gambar=="image/jpg" || $jenis_gambar=="image/gif"  || $jenis_gambar=="image/png")
      
         {
          $photo  = $namafolder . basename($_FILES['photo']['name']);
          if  (!move_uploaded_file($_FILES['photo']['tmp_name'], $photo))
            { die("Gambar gagal dikirim"); }
         
         } else { die("Jenis gambar yang anda kirim salah. Harus .jpg .gif .png"); }
         
    }
        mysql_query ("insert into company_profile values('$nama','$alamat','$tlp','$fax','$email','$website','$kontak','$npwp','$tgl','$photo') ");
        echo  "<h1>Berhasil</h1>";
        echo  "<br>";
      
    }
    } 
  
   
  
?>    

field lain masuk ke databasenya cuma yang photo tidak muncul error Notice: Undefined variable: photo in C:\xampp\htdocs\ABMS\add_company_profile.php on line 166
