標籤：class users new 擷取 int for put input form表單
一、註冊頁面
1、首先要用form表單做一個註冊頁面：
<h1>註冊</h1><form action="chuli.php" method="post"><div>使用者名稱：<input type="text" name="uid" /></div><div>密碼：<input type="password" name="pwd" /></div><div>姓名：<input type="text" name="name" /></div><div>性別：男<input type="radio" name="sex" value="1"/>女<input type="radio" name="sex" value="0"/></div><div>生日：<input type="text" name="birthday" /></div><div><input type="submit" value="註冊" /></div></form>
2、做一個純php的頁面來擷取註冊頁面的資料
<?php//1.取提交的資料$uid=$_POST["uid"];//如果是get，就用$_GET()$pwd=$_POST["pwd"];$name=$_POST["name"];$sex=$_POST["sex"];$birthday=$_POST["birthday"];//2.向資料庫寫入$db=new MySQLi("localhost","root","123","text_0306");$sql="insert into usersvalues(‘{$uid}‘,‘{$pwd}‘,‘{$name}‘,{$sex},‘{$birthday}‘)";//這裡取每個列名if($db->query($sql)){ echo"註冊成功";}else{ echo"註冊失敗"; }?>
二、登陸頁面
1、做一個登陸頁面的form表單：
<body><h1>登陸頁面</h1><form action="denglu1.php" method="post"><div>使用者名稱：<input type="text" name="uid" /></div><div>密碼：<input type="password" name="pwd" /></div><div><input type="submit" value="登入" /></div></form></body>
2、做一個純php頁面來擷取登陸頁面的資料
<?php//1.取提交的資料$uid=$_POST["uid"];$pwd=$_POST["pwd"];//2.向資料庫寫入$db=new MySQLi("localhost","root","123","text_0306");$sql="select pwd from users where uid=‘{$uid}‘";//用密碼來驗證使用者名稱，防止被入侵$result=$db->query($sql);$arr=$result->fetch_row();if($arr[0]==$pwd && !empty($pwd))//驗證索引是否等於密碼且不可為空{ echo"登陸成功";}else{ echo"登入失敗"; }?>
