本文实例为大家分享了PHP实现简单注册登录系统的具体代码,供大家参考,具体内容如下
目录结构如下,其中function文件夹下包含两个函数文件,uploads文件夹用于存放上传的文件。
注:博主使用的是php5,使用php7的小伙伴运行报错的话有一部分原因是新的语法造成的,修改成新语法就可以了
html页面
登录页面
index.html
<form action=\"login_process.php\" method=\"POST\"> 登录 <input type=\"text\" name=\"userName\" size=\"20\" maxlength=\"15\" placeholder=\"请填写用户名及域名\"> <br> 注册 <input type=\"password\" name=\"password\" size=\"20\" maxlength=\"15\"> <br> <input type=\"submit\" value=\"登录\"> <input type=\"button\" onclick=\"window.location.href=\'register.html\'\" value=\"注册\"> </form>
注册页面
register.html
<h2>用户注册登录系统</h2> <hr> <form action=\"register.php\" method=\"POST\" enctype=\"multipart/form-data\"> 用户名: <input type=\"text\" name=\"userName\" size=\"20\" maxlength=\"15\" placeholder=\"必须填写用户名\"> @ <select name=\"domain\" id=\"\"> <option value=\"@163.com\" selected>163.com</option> <option value=\"@126.com\">126.com</option> </select> <br> 登录密码: <input type=\"password\" name=\"password\" size=\"20\" maxlength=\"15\"> <br> 确认密码: <input type=\"password\" name=\"confirmPassword\" size=\"20\" maxlength=\"15\"> <br> 选择性别: <input type=\"radio\" name=\"sex\" value=\"male\" checked>男 <input type=\"radio\" name=\"sex\" value=\"female\">女 <br> 个人爱好: <input name=\"interests[]\" type=\"checkbox\" value=\"music\">音乐 <input name=\"interests[]\" type=\"checkbox\" value=\"game\">游戏 <input name=\"interests[]\" type=\"checkbox\" value=\"film\">电影 <br> 个人相片 <input type=\"hidden\" name=\"MAX_FILE_SIZE\" value=\"1024\"> <input type=\"file\" name=\"myPicture\" size=\"25\" maxlength=\"100\"> <br> 备注信息: <textarea name=\"remark\" cols=\"30\" rows=\"4\" placeholder=\"请填写备注信息\"></textarea> <br> <input type=\"submit\" name=\"submit\" value=\"注册\"> <input type=\"reset\" name=\"cancel\" value=\"重填\"> </form>
功能实现文件
实现登录功能
login_process.php
<?php include_once(\"function/database.php\"); // $userName = $_POST[\'userName\']; // $password = $_POST[\'password\']; $userName = addslashes($_POST[\'userName\']); $password = addslashes($_POST[\'password\']); getConnect(); $loginSQL = \"select * from users where userName=\'$userName\' and password=\'$password\'\"; echo $loginSQL; $resultLogin = mysql_query($loginSQL); if (mysql_num_rows($resultLogin) > 0) { echo \"登录成功\"; } else { echo \"登录失败\"; } closeConnect(); ?>
实现注册功能
register.php
<?php include_once(\"function/fileSystem.php\"); include_once(\"function/database.php\"); if (empty($_POST)) { exit(\"您提交的表单数据超过post_max_size! <br>\"); } // 判断输入密码与确认密码是否相同 $password = $_POST[\'password\']; $confirmPassword = $_POST[\'confirmPassword\']; if ($password != $confirmPassword) { exit(\"输入的密码与确认密码不相等!\"); } $userName = $_POST[\'userName\']; $domain = $_POST[\'domain\']; $userName = $userName . $domain; // 判断用户名是否重复 $userNameSQL = \"select * from users where userName = \'$userName\'\"; getConnect(); $resultSet = mysql_query($userNameSQL); if (mysql_num_rows($resultSet) > 0) { exit(\"用户名已被占用,请更换其他用户名\"); } $sex = $_POST[\'sex\']; if (empty($_POST[\'interests\'])) { $interests = \"\"; } else { $interests = implode(\";\", $_POST[\'interests\']); } $remark = $_POST[\'remark\']; $myPictureName = $_FILES[\'myPicture\'][\'name\']; $registerSQL = \"insert into users values(null, \'$userName\', \'$password\', \'$sex\', \'$interests\', \'$myPictureName\', \'$remark\')\"; $message = upload($_FILES[\'myPicture\'], \"uploads\"); if ($message == \"上传成功\" || $message == \"没有上传\") { mysql_query($registerSQL); $userID = mysql_insert_id(); echo \"注册成功<br>\"; } else { exit($message); } $userSQL = \"select * from users where user_id = \'$userID\'\"; $userResult = mysql_query($userSQL); if ($user = mysql_fetch_array($userResult)) { echo \"您的注册用户名为:\" . $user[\'userName\']; } else { exit(\"用户注册失败!\"); } closeConnect();
函数文件(function文件夹)
实现数据库连接与关闭的函数
database.php
<?php $databaseConnection = null; function getConnect() { $hosthome = \"localhost\"; $database = \"register\"; $userName = \"root\"; $password = \"123456\"; global $databaseConnection; $databaseConnection = @mysql_connect($hosthome, $userName, $password) or die (mysql_error()); mysql_query(\"set names gbk\"); @mysql_select_db($database, $databaseConnection) or die (mysql_error()); } function closeConnect() { global $databaseConnection; if ($databaseConnection) { @mysql_close($databaseConnection) or die (mysql_error()); } } ?>
实现文件上传的函数
fileSystem.php
<?php function upload($file, $filePath) { $error = $file[\'error\']; switch ($error) { case 0: $fileName = $file[\'name\']; $fileTemp = $file[\'tmp_name\']; $destination = $filePath . \"/\" . $fileName; move_uploaded_file($fileTemp, $destination); return \"上传成功\"; case 1: return \"上传超过upload_max_filesize\"; case 2: return \"上传文件超过form的MAX_FILE_SIZE\"; case 3: return \"附件部分上传\"; case 4: return \"没有上传\"; } } ?>
