html前端页面代码如下:
<html> <head> <title>enter password</title> </head> <body> <form name="forml" method="post" action="cookiebasedpasswordlogin.php"> <table> <tr> <td colspan="2" > <div align="center"><b>please specify the password</b></div> </td> </tr> <tr>> <td> <div align="right">customer id</div> </td> <td> <input type="text" name="username"> </td> </tr> <tr> <td> <div align="right">password</div> </td> <td> <input type="password" name="password"> </td> </tr> <tr> <td colspan="2"> <center> <input type="submit" name="submit" value="login"> </center> </td> </tr> </table> </form> </body> </html>
后端PHP代码如下:
<?php
$now = getdate();
$storetime= $now["weekday"] . " " . $now["month"] ." " . $now["year"] ;
$storetime.=" time : ";
if ($now["hours"] < 10) {
$storetime.= "0" . $now["hours"];
} else {
$storetime.= $now["hours"];
}
$storetime.= ":";
if ($now["minutes"]<10) {
$storetime.= "0" . $now["minutes"];
} else {
$storetime.= $now["minutes"];
}
$storetime.= ": ";
if ($now["seconds"] <10) {
$storetime.= "0" . $now["seconds"];
} else {
$storetime.= $now["seconds"];
}
if (isset($data)) {
$counter=++$data[l];
setcookie("data[0]",$storetime,time() + (60*60*24));
setcookie("data[l]", $counter,time() + (60*60*24)); setcookie("data[2]",$username,time() + (60*60*24));
echo "<b><center>hi " . $data[2] . " ! !</center></b><br>n";
echo "<b><center>last login time :" .$data[0] . "</center></b><br>n";
echo "<b><center>current date :" .$storetime. "</center></b><br>n";
echo "<b><center>page view count :" . $data[l]. "</center></b><br>n";
echo "<b><center>you have successfully logged in!</center></b>";
echo ("<b><contor>you can access this area without entering a password for the next 24 hours!</center></b>");
} else {
if (isset($username) && isset($password)) {
if ($password=="superpass") {
$counter=0;
setcookie("data[0]",$storetime,time() + (60*60*24));
setcookie("data[l]",$counter,time() + (60*60*24));
setcookie("data[2]",$username,time() + (60*60*24));
$url="location: cookieimp.php";
header($url);
}else{
echo "<hl><center>invalid password!!!</center></hl>";
}
}
}
