Cara Membuat Login dengan PHP dan MySQL

Untuk membuat Form Login dan proses Login dengan PHP dan MySQL cukup mudah, kamu hanya membutuhkan kode form dan prosesnya, berikut contohnya

Dibawah ini adalah contoh kode Form Login

<html>
   
   <head>
      <title>Login Page</title>
      
      <style type = "text/css">
         body {
            font-family:Arial, Helvetica, sans-serif;
            font-size:14px;
         }
         label {
            font-weight:bold;
            width:100px;
            font-size:14px;
         }
         .box {
            border:#666666 solid 1px;
         }
      </style>
      
   </head>
   
   <body bgcolor = "#FFFFFF">
	
      <div align = "center">
         <div style = "width:300px; border: solid 1px #333333; " align = "left">
            <div style = "background-color:#333333; color:#FFFFFF; padding:3px;"><b>Login</b></div>
				
            <div style = "margin:30px">
               
               <form action = "" method = "post">
                  <label>UserName  :</label><input type = "text" name = "username" class = "box"/><br /><br />
                  <label>Password  :</label><input type = "password" name = "password" class = "box" /><br/><br />
                  <input type = "submit" value = " Submit "/><br />
               </form>
               
               <div style = "font-size:11px; color:#cc0000; margin-top:10px"><?php echo $error; ?></div>
					
            </div>
				
         </div>
			
      </div>

   </body>
</html>

Lalu kode Proses Login

<?php
   include("config.php");
   session_start();
   
   if($_SERVER["REQUEST_METHOD"] == "POST") {
      
      $myusername = mysqli_real_escape_string($db,$_POST['username']);
      $mypassword = mysqli_real_escape_string($db,$_POST['password']); 
      
      $sql = "SELECT id FROM admin WHERE username = '$myusername' and passcode = '$mypassword'";
      $result = mysqli_query($db,$sql);
      $row = mysqli_fetch_array($result,MYSQLI_ASSOC);
      $active = $row['active'];
      
      $count = mysqli_num_rows($result);
      		
      if($count == 1) {
         session_register("myusername");
         $_SESSION['login_user'] = $myusername;
         
         header("location: welcome.php");
      }else {
         $error = "Your Login Name or Password is invalid";
      }
   }
?>

Cukup mudah bukan ? Silahkan dicoba 🙂
