这是在我的页面中,它应该检查用户是否登录 http://carbonyzed.co.uk/Websites/Jason/sites/2/test/login_success.php
但任何人都可以评估它,而不仅仅是那些登录的人
<?php
session_start();
if( isset($_SESSION["myusername"]) ){
header("location:main_login.html");
}
?>
我试过了
if(isset($ _ SESSION ["myusername"])){
和
if(isset($ _ SESSION [$ myusername])){
登录代码可能还没有创建会话？
<?php
ob_start();
$host="ClubEvents.db.9606426.hostedresource.com"; // Host name
$username="ClubEventsRead"; // Mysql username
$password="Pa55word!"; // Mysql password
$db_name="ClubEvents"; // Database name
$tbl_name="members"; // Table name
// Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");
// Define $myusername and $mypassword
$myusername=$_POST['myusername'];
$mypassword=$_POST['mypassword'];
// To protect MySQL injection (more detail about MySQL injection)
$myusername …我的代码中有以下内容
session_register("myusername");
session_register("mypassword");
内
<?php
ob_start();
$host="ClubEvents.db.9606426.hostedresource.com"; // Host name
$username="ClubEventsRead"; // Mysql username
$password="Pa55word!"; // Mysql password
$db_name="ClubEvents"; // Database name
$tbl_name="members"; // Table name
// Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");
// Define $myusername and $mypassword
$myusername=$_POST['myusername'];
$mypassword=$_POST['mypassword'];
// To protect MySQL injection (more detail about MySQL injection)
$myusername = stripslashes($myusername);
$mypassword = stripslashes($mypassword);
$myusername = mysql_real_escape_string($myusername);
$mypassword = mysql_real_escape_string($mypassword);
$sql="SELECT * FROM $tbl_name WHERE username='$myusername' and password='$mypassword'";
$result=mysql_query($sql); …
