Hufh setelah lama bergelut dengan semua tugas-tugas kuliah akhirnya saya bisa menulis lagi di blog tercinta ini, yup kali ini saya akan membuat sebuah aplikasi Login Member dengan PHP MySQL ya kira kira nanti hasil akhirnya seperti ini :
Ok Langsung Saja kita praktekan pertama-tama kita buat terlebih dahulu file untuk penghubung ke databasenya :
config.php 03 | mysql_connect( "localhost" , "root" , "" ); |
10 | mysql_select_db( "login" ); |
nah kalo sudah kita buat penghubungnya sekarang kita buat form loginya.
login.php 05 | if (ISSET( $_SESSION [ 'username' ])){ |
06 | header( "location: index.php" ); |
09 | <style type= "text/css" > |
12 | font-family: Arial, Helvetica, sans-serif; |
17 | .style5 {color: #FFFFFF} |
18 | .style9 {color: #000000; font-weight: bold; } |
19 | .style10 {color: #000000} |
24 | <form id= "form1" name= "form1" method= "post" action= "cek.php" > |
26 | <table width= "329" border= "0" align= "center" cellpadding= "0" cellspacing= "2" > |
29 | <td height= "44" colspan= "4" bgcolor= "#999999" ><div align= "center" >CYBER LOG-IN </div></td> |
32 | <td width= "10" > </td> |
33 | <td width= "133" ><span> User Name </span></td> |
34 | <td width= "6" ><span>:<span>:</span></span></td> |
35 | <td width= "306" ><input name= "username" type= "text" /></td> |
39 | <td><span>Password</span></td> |
40 | <td><span>:<span>:</span></span></td> |
41 | <td><input name= "password" type= "password" /></td> |
47 | <td><input name= "submit" value= "Login" type= "submit" /></td> |
50 | <td height= "39" colspan= "4" bgcolor= "#999999" ><span>Bukan Member? Silahkan Daftar </span><a href= "signup.php" >Daftar</a> </td> |
cek.php 09 | $username = $_POST [ 'username' ]; |
10 | $password = $_POST [ 'password' ]; |
13 | $password_md5 = md5( $password ); |
16 | $perintah = "select * from user where username='$username'&&password='$password_md5'" ; |
17 | $perintah_di_query = mysql_query( $perintah ); |
18 | $ketersediaan = mysql_num_rows( $perintah_di_query ); |
21 | if ( $ketersediaan >= 1 ){ |
22 | $_SESSION [ 'username' ] = $username ; |
23 | header( "location: index.php" ); |
25 | header( "location: login.php" ); |
nah sekarang kita buat untuk halaman utamanya !
index.php 06 | if (ISSET( $_SESSION [ 'username' ])){ |
07 | echo "Anda Login Sebagai " ; |
08 | echo $_SESSION [ 'username' ]; |
09 | echo "<br><a href='logout.php'>logout</a>" ; |
13 | header( "location: login.php" ); |
19 | <h2>Selamat Datang di HalamanUtama !! <br> |
setelah itu kita buat pendaftaran usernya.
signup.php 01 | <style type= "text/css" > |
03 | .style1 { font-family: Arial, Helvetica, sans-serif; |
08 | .style10 {color: #000000} |
09 | .style5 {color: #FFFFFF} |
10 | .style9 {color: #000000; font-weight: bold; } |
13 | <form method= "post" action= "signup_process.php" > |
14 | <pre><h2>Form Pendaftaran</h2> |
16 | <table width= "355" border= "0" align= "center" cellpadding= "0" cellspacing= "2" > |
18 | <td height= "44" colspan= "4" bgcolor= "#999999" ><div align= "center" >REGISTRATION </div></td> |
21 | <td width= "7" > </td> |
22 | <td width= "161" ><span> Masukan User Name </span></td> |
23 | <td width= "10" ><span>:<span>:</span></span></td> |
24 | <td width= "167" ><input name= "username" type= "text" /></td> |
28 | <td><span>Masukan Password</span></td> |
29 | <td><span>:<span>:</span></span></td> |
30 | <td><input name= "password" type= "password" /></td> |
36 | <td><input name= "submit" value= "Daftar" type= "submit" /></td> |
39 | <td height= "39" colspan= "4" bgcolor= "#999999" > </td> |
signup_process 05 | $username = $_POST [ 'username' ]; |
06 | $password = $_POST [ 'password' ]; |
07 | $password_md5 = md5( $password ); |
10 | if ( $username == '' || $password == '' ){ |
11 | echo "Data tidak lengkap<br--><a href=signup.php>Back</a>" ; |
15 | $perintah = "insert into user values ('$username', '$password_md5')" ; |
16 | $perintah_di_query = mysql_query( $perintah ); |
19 | if ( $perintah_di_query ) { |
20 | echo "Daftar berhasil, silakan <a href='index.php'>login</a>" ; |
24 | echo "Daftar gagal atau username telah terdaftar silakan <a href='signup.php'>Ulangi</a> atau <a href='login.php'>Login</a>" ; |
hufh alhamdulillah selesai juga ! memang dalam pembuatan Sistem Login ini harus dilakukan dengan sangat teliti.
