I'm trying to make an "asp.net site.Master" functional page with PHP using URL params to show or hide content in the page but it looks like only one of the params is working.
Code here:
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<title>System</title>
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous">

</head>
<body>
<nav class="navbar navbar-expand-lg navbar-dark bg-dark sticky-top">
<a runat="server" class="navbar-brand" href="~/Default">LOGO</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarText" aria-controls="navbarText" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarText">
<ul class="nav navbar-nav">
<li><a class="nav-link" href="index.php?index=one">one</a></li>
<li><a class="nav-link" href="index.php?index=two">two</a></li>
</ul>
</div>
</nav>
<?php $mypage = isset($_GET['index']);
switch ($mypage) {
case "one":
@include("./one.php");
break;
case "two":
@include("./two.php");
break;
}
?>
</body>
</html>
Doesn't matter which option I click on the navbar because it always shows me the "one" option.
Pages "one" and "two" are just an empty html with "one" and "two"
I'm sorry if I'm not as descriptive as it should, it's my first time asking here.
Thx!
