在网站上工作,实现课程作业的登录功能。目前已经编写了脚本文件但是当我测试它时,它会加载login.php,这是我用于脚本的内容。
<form action="login.php" method="post">
<div class="imgcontainer">
<img src="img/icons/avatar.png" alt="ELEAGUE" class="avatar">
</div>
<div class="container">
<label><b>Username</b></label>
<input type="text" name="username" maxlength="40">
<label><b>Password</b></label>
<input type="password" name="pass" maxlength="50">
<button type="submit">Login</button>
<input type="checkbox" checked="checked"> Remember me
</div>
<div class="container" style="background-color:#fff">
<span class="psw">Forgot <a href="#">password?</a></span>
</div>
</form>
脚本是
<?php
//Connects to your Database
$conect = mysqli_connect("db location","username","password", "forks") or die(mysql_error());
//Checks if there is a login cookie
if(isset($_COOKIE['ID_your_site'])){ //if there is, it logs you in and directs you to the members page
$username = $_COOKIE['ID_your_site'];
$pass = $_COOKIE['Key_your_site'];
$check = mysqli_query($conect, "SELECT * FROM users WHERE username = '$username'")or die(mysql_error());
while($info = mysqli_fetch_array( $check )){
if ($pass != $info['password']){}
else{
header("Location: login.php");
}
}
}
//if the login form is submitted
if (isset($_POST['submit'])) {
// makes sure they filled it in
if(!$_POST['username']){
die('You did not fill in a username.');
}
if(!$_POST['pass']){
die('You did not fill in a password.');
}
// checks it against the database
if (!get_magic_quotes_gpc()){
$_POST['email'] = addslashes($_POST['email']);
}
$check = mysqli_query($conect, "SELECT * FROM users WHERE username = '".$_POST['username']."'")or die(mysql_error());
//Gives error if user dosen't exist
$check2 = mysqli_num_rows($check);
if ($check2 == 0){
die('That user does not exist in our database.<br /><br />If you think this is wrong <a href="login.php">try again</a>.');
}
while($info = mysqli_fetch_array( $check )){
$_POST['pass'] = stripslashes($_POST['pass']);
$info['password'] = stripslashes($info['password']);
$_POST['pass'] = md5($_POST['pass']);
//gives error if the password is wrong
if ($_POST['pass'] != $info['password']){
die('Incorrect password, please <a href="login.php">try again</a>.');
}
else{ // if login is ok then we add a cookie
$_POST['username'] = stripslashes($_POST['username']);
$hour = time() + 3600;
setcookie(ID_your_site, $_POST['username'], $hour);
setcookie(Key_your_site, $_POST['pass'], $hour);
//then redirect them to the members area
header("Location: members.php");
}
}
}
else{
// if they are not logged in
?>
