當(dāng)初我覺(jué)得一個(gè)網(wǎng)站上注冊(cè)和登錄這兩個(gè)功能很神奇,后來(lái)自己研究一下發(fā)現(xiàn)其實(shí)道理很簡(jiǎn)單,接下來(lái)看一下怎么實(shí)現(xiàn)的吧。。。。
我在我的電腦上建了幾個(gè)文件:
login.html (登錄頁(yè)面)
register.html(注冊(cè)頁(yè)面)
success.html(登錄成功跳轉(zhuǎn)頁(yè)面)
return.html(注冊(cè)成功頁(yè)面)
login.php
register.php
登錄界面和注冊(cè)界面以及success.html并沒(méi)有
什么都是些html標(biāo)記如下:
<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>登錄界面</title> </head> <body> <form method="post" action="login.php"> 賬號(hào): <input type="text" name="usernamel"><br/><br/> 密碼: <input type="password" name="passwordl"> <input type="submit" value="登錄" name="subl"> <a >沒(méi)有賬號(hào),注冊(cè)</a> </form> </body> </html>
<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>會(huì)員注冊(cè)</title> </head> <body> <form method="post" action="register.php"> 賬 戶: <input type="text" name="username"><br/><br/> 密 碼: <input type="password" name="password"><br/><br/> 密碼確認(rèn): <input type="password" name="password2"> <input type="submit" value="注冊(cè)" name="sub"> </form> </body> </html>
return.html是注冊(cè)成功之后呈現(xiàn)的頁(yè)面,里面有一段js代碼是用來(lái)定時(shí)返回登錄界面的
<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>無(wú)標(biāo)題文檔</title> </head> <body> 注冊(cè)成功!<br/> 5秒后返回登錄界面<br/> 你也可以直接點(diǎn)擊回到<a >登錄頁(yè)面</a> <script type="text/javascript"> setTimeout("ren()",5000); function ren() { window.location="http://127.0.0.1:8080/login.html"; } </script> </body> </html>
register.php這是與注冊(cè)頁(yè)面相對(duì)應(yīng)后臺(tái)頁(yè)面
<?php $link=mysql_connect("localhost","root","207207");//鏈接數(shù)據(jù)庫(kù) header("Content-type:text/html;charset=utf-8"); if($link) { //echo"鏈接數(shù)據(jù)庫(kù)成功"; $select=mysql_select_db("login",$link);//選擇數(shù)據(jù)庫(kù) if($select) { //echo"選擇數(shù)據(jù)庫(kù)成功!"; if(isset($_POST["sub"])) { $name=$_POST["username"]; $password1=$_POST["password"];//獲取表單數(shù)據(jù) $password2=$_POST["password2"]; if($name==""||$password1=="")//判斷是否填寫 { echo"<script type="."""."text/javascript".""".">"."window.alert"."("."""."請(qǐng)?zhí)顚懲瓿桑?.""".")".";"."</script>"; echo"<script type="."""."text/javascript".""".">"."window.location="."""."http://127.0.0.1:8080/register.html"."""."</script>"; exit; } if($password1==$password2)//確認(rèn)密碼是否正確 { $str="select count(*) from register where username="."'"."$name"."'"; $result=mysql_query($str,$link); $pass=mysql_fetch_row($result); $pa=$pass[0]; if($pa==1)//判斷數(shù)據(jù)庫(kù)表中是否已存在該用戶名 { echo"<script type="."""."text/javascript".""".">"."window.alert"."("."""."該用戶名已被注冊(cè)".""".")".";"."</script>"; echo"<script type="."""."text/javascript".""".">"."window.location="."""."http://127.0.0.1:8080/register.html"."""."</script>"; exit; } $sql="insert into register values("."""."$name".""".","."""."$password1".""".")";//將注冊(cè)信息插入數(shù)據(jù)庫(kù)表中 //echo"$sql"; mysql_query($sql,$link); mysql_query('SET NAMES UTF8'); $close=mysql_close($link); if($close) { //echo"數(shù)據(jù)庫(kù)關(guān)閉"; //echo"注冊(cè)成功!"; echo"<script type="."""."text/javascript".""".">"."window.location="."""."http://127.0.0.1:8080/return.html"."""."</script>"; } } else { echo"<script type="."""."text/javascript".""".">"."window.alert"."("."""."密碼不一致!".""".")".";"."</script>"; echo"<script type="."""."text/javascript".""".">"."window.location="."""."http://127.0.0.1:8080/register.html"."""."</script>"; } } } } ?>
login.php登錄界面對(duì)應(yīng)后臺(tái)文件
<?php header("Content-type:text/html;charset=utf-8"); $link=mysql_connect("localhost","root","207207"); if($link) { $select=mysql_select_db("login",$link); if($select) { if(isset($_POST["subl"])) { $name=$_POST["usernamel"]; $password=$_POST["passwordl"]; if($name==""||$password=="")//判斷是否為空 { echo"<script type="."""."text/javascript".""".">"."window.alert"."("."""."請(qǐng)?zhí)顚懻_的信息!".""".")".";"."</script>"; echo"<script type="."""."text/javascript".""".">"."window.location="."""."http://127.0.0.1:8080/login.html"."""."</script>"; exit; } $str="select password from register where username="."'"."$name"."'"; mysql_query('SET NAMES UTF8');20 $result=mysql_query($str,$link); $pass=mysql_fetch_row($result); $pa=$pass[0]; if($pa==$password)//判斷密碼與注冊(cè)時(shí)密碼是否一致 { echo"登錄成功!"; echo"<script type="."""."text/javascript".""".">"."window.location="."""."http://127.0.0.1:8080/success.html"."""."</script>"; } { echo"<script type="."""."text/javascript".""".">"."window.alert"."("."""."登錄失敗!".""".")".";"."</script>"; echo"<script type="."""."text/javascript".""".">"."window.location="."""."http://127.0.0.1:8080/login.html"."""."</script>"; } } } } ?>
自己閑來(lái)無(wú)事做的還有許多要完善的地方,歡迎大家提問(wèn)討論,提供更簡(jiǎn)便的方法!
