I have a script where when a user get verified he/she is brought to Home.php
. At the moment Home.php
doesn't do much. But in the bottom left hand corner I have a log out button. And as you know when the user clicks on this button he expects his session to be destroyed and for him to be redirected to a log in page. Unfortunately you can't make a click listener in php
. I have browsed for an hour looking for a solution but I have not been able to find the right key word or something.
This is my code
EDIT: You only really have to read some code from Home.php
the est is only if someoe wants to run the code if they are not sure of their answer
Index.php
(Login Page)
<?php
session_start();
mysql_connect("localhost","root","") or die ("cannot");
mysql_select_db("virtualdiary") or die ("db");
if (isset ($_POST["Username"])&& isset($_POST["Password"]))
{
$Username = $_POST["Username"];
$Password = $_POST["Password"];
$_SESSION["username"] = $Username;
$DB_Check = " SELECT * from users Where username = '".$Username."' and password = '".$Password."' " ;
$result = mysql_query($DB_Check);
if(mysql_fetch_assoc($result) === false){
$error = "invalid username or password";
}else{
header( 'Location: Home.php' ) ;
}
}

From what I have found from searching around I will need a Home.js
file with an ajax call. I don't know the first thing about Ajax so I will probably need code to paste or a very blunt tutorial.
Thanks
