我正在尝试重新设计一个登录页面，将登录/注册表单合并到一个页面中，而不是有两个单独的页面。以前我的登录和注册页面都通过PHP正确访问我的数据库。
我试图简单地复制我之前为每个人工作的元素，但是下面的教程页面，但我的数据库连接/ php似乎没有做任何事情。
我正在遵循http://codyhouse.co/gem/loginsignup-modal-window/
中列出的这种方法新的index.php
<?php
session_start();
?>
<?php
//Log out and delete cookie
/* if(isset($_GET['logout'])){
session_destroy();
}*/
//After validation, then check the entered data
if( isset($_POST['log_username']) && isset($_POST['log_password'])) {
$log_username = $_POST['log_username'];
$log_password = $_POST['log_password'];
$con =mysql_connect("localhost", "user4321", "4321");
mysql_select_db('supernatural',$con);
$sql = "SELECT * FROM user WHERE user_username='$log_username' AND user_password2='$log_password'";
$sql_E = "SELECT * FROM user WHERE user_username='$log_username'";
$loginShow = mysql_query($sql);
$loginShow_E = mysql_query($sql_E);
$lookOver=mysql_num_rows($loginShow);
$lookOver_E=mysql_num_rows($loginShow_E);
$row = mysql_fetch_array($loginShow);
$row_E = mysql_fetch_array($loginShow_E);
$myuser = $row['user_fn'];
//$cookie_name = "cook_name";
if($lookOver == 1){
//Set Cookie for 1 day
//setcookie($cookie_name,"$myuser", time() + 86400,"/");
$_SESSION['loggedin'] = true;
$_SESSION['user'] = $myuser;
$_SESSION['userid'] = $row['user_id'];
$_SESSION['userlevel'] = $row['level'];
header("location: map.php");
/*
if(!isset($_COOKIE[$cookie_name])) {
echo "Cookie name does not exist!";
} else {
echo "Cookie is named: <br>" . $_COOKIE[$cookie_name]."<a href='?logout'>Log Out</a>";
}
*/
} else {
//If only password is wrong, then it will send an email with password.
if($lookOver_E == 1){
echo "Don't remember your password? </br> <a class='refound_P' href='register.php'>Register a new account with a new email</a>";
/*href='found.php '>Send me a email with my password.</a>"; */
//If there is not one data relevant to, then it requires users reset.
}else{
echo "</br>Don't remember your Username? </br> <a class='refound_E' href='register.php'>Register a new account with a new email</a>";
}
}
mysql_close($con);
}
//echo json_encode($_SESSION['loggedin'] ? 'true' : 'false');
?>

我只是试图让登录部分（不是寄存器）工作开始，但即使这样做也没有做任何事情。
我基本上复制了我之前登录的内容，但无法解决为什么它无法正常工作！所有数据库凭据都是正确的。我在这里错过了一些非常简单的东西吗？
答案 0 :(得分：0)
问题是没有处理查询。您在登录表单中没有name属性。在表单中添加name="log_username"和name="log_username"，然后$log_username = $_POST['log_username']和$log_password = $_POST['log_password']将包含值。
同样在表单操作中，将其留空，表单将提交给自己。为登录表单和注册表单中的所有输入字段添加名称属性。
以下是登录表单的修复：

<form class="cd-form" action="" method="post">
<p class="fieldset">
<label class="image-replace cd-username" for="log_username">Login</label>
