i have an issue, my code works wonderfully for the pupose its designed for however for security reasons i need th epages page my login page to have either randomized links or just links that cannot be bookmakred too so that one can bypass the login page. My login page is set up to do a basic query from a table of usernames and passwords and so far thats been great but like i said before i need the page to be random each time. How do i go about doing this? I know only what i have read so far online and thats very little about this subject. Here is my code so far:
<?php
session_start();
$con = mysqli_connect("localhost", "root", "", "numbers") or die(mysqli_error($con));
if(isset($_POST['login'])){
$myusername=mysqli_real_escape_string($con,$_POST['username']);
$mypassword=mysqli_real_escape_string($con,$_POST['password']);
$sql="SELECT username, password FROM admin WHERE username='".$myusername."' AND password='".$mypassword."'";
$check= mysqli_query($con,$sql);
$row = mysqli_fetch_row($check);
if($row[0]!="" && $row[1] !=""){
## set logged_in to true
$_SESSION['logged_in']= true;
## set username session
$_SESSION['username'] = $row[0];
header('location: form.php');
exit();
}
else
{
$error="Your Login Name or Password is invalid";
//echo "$error";
//echo "<META http-equiv=' refresh' ;URL='index.php'>";
}
}
?>
