<?php
if (isset($_POST['email'])) {
//Connect to the database through our include 
require("db.php");

$email = stripslashes($_POST['email']);
$email = strip_tags($email);
$email = mysql_real_escape_string($email);
$password = preg_replace("[^A-Za-z0-9]", "", $_POST['password']); // filter everything but numbers and letters
$password = md5($password);
// Make query and then register all database data that -
// cannot be changed by member into SESSION variables.
// Data that you want member to be able to change -
// should never be set into a SESSION variable.
$sql = mysql_query("SELECT * FROM members WHERE email='$email' AND password='$password' AND emailactivated='1'");

从您的 FORM 属性中删除 enctype,因为您没有上传文件,只需使用方法 =“POST”
