Simple PHP Login Script
This is simple PHP login script
Our 1st step is to Create table “mydata” in database “test”.
———————————————————————–
CREATE TABLE ‘mydata’ (
`id` int(4) NOT NULL auto_increment,
`username` varchar(65) NOT NULL default ”,
`password` varchar(65) NOT NULL default ”,
PRIMARY KEY (`id`)
) TYPE=MyISAM AUTO_INCREMENT=2 ;
–
– Inserting data for table `mydata`
–
INSERT INTO `mydata` VALUES (1, ‘test’, ‘pass123′);
———————————————————————–
2. Create file main_login.php.
———————————————————————–
<table width=”300″ border=”0″ align=”center” cellpadding=”0″ cellspacing=”1″ bgcolor=”#CCCCCC”>
<tr>
<form name=”form1″ method=”post” action=”checklogin.php”>
<td>
<table width=”100%” border=”0″ cellpadding=”3″ cellspacing=”1″ bgcolor=”#FFFFFF”>
<tr>
<td colspan=”3″><strong>Member Login </strong></td>
</tr>
<tr>
<td width=”78″>Username</td>
<td width=”6″>:</td>
<td width=”294″><input name=”myusername” type=”text” id=”myusername”></td>
</tr>
<tr>
<td>Password</td>
<td>:</td>
<td><input name=”mypassword” type=”text” id=”mypassword”></td>
</tr>
<tr>
<td> </td>
<td> </td>
<td><input type=”submit” name=”Submit” value=”Login”></td>
</tr>
</table>
</td>
</form>
</tr>
</table>
———————————————————————–
3. Create file checklogin.php.
Dont forget to create a database named TEST
———————————————————————–
<?php
$host=”localhost”; // Host name
$username=”root”; // Mysql username
$password=”"; // Mysql password
$db_name=”TEST”; // Database name
$tbl_name=”mydata”; // Table name
// Connect to server and select databse.
mysql_connect(”$host”, “$username”, “$password”)or die(”cannot connect”);
mysql_select_db(”$db_name”)or die(”cannot select DB”);
// username and password sent from form
$myusername=$_POST['myusername'];
$mypassword=$_POST['mypassword'];
// To protect MySQL injection
$myusername = stripslashes($myusername);
$mypassword = stripslashes($mypassword);
$myusername = mysql_real_escape_string($myusername);
$mypassword = mysql_real_escape_string($mypassword);
$sql=”SELECT * FROM $tbl_name WHERE username=’$myusername’ and password=’$mypassword’”;
$result=mysql_query($sql);
// Mysql_num_row is counting table row
$count=mysql_num_rows($result);
// If result matched $myusername and $mypassword, table row must be 1 row
if($count==1){
// Register $myusername, $mypassword and redirect to file “login_success.php”
session_register(”myusername”);
session_register(”mypassword”);
header(”location:login_success.php”);
}
else {
echo “Wrong Username or Password”;
}
?>
———————————————————————–
4. Create file login_success.php.
———————————————————————–
<?
session_start();
if(!session_is_registered(myusername)){
header(”location:main_login.php”);
}
?>
<html>
<body>
You Have Successfully Logged In.<br>
<a href=”logout.php”>Log Out </a></body>
</html>
———————————————————————–
5. Create file logout.php
———————————————————————–
// Put this code in first line of web page.
<?
session_start();
session_destroy();
?>
