PHP My Multi User Login System Won't Work

I've been trying to make a multi user login system but when I try to log on it stays at the login page (index.php) page. What can I do?

index.php

PHP:
<form method="post" class="form-horizontal">

    <div class="form-group">
        <label class="col-sm-3 control-label">Email</label>
        <div class="col-sm-6">
            <input type="text" name="txt_email" class="form-control" placeholder="enter email" />
        </div>
    </div>

    <div class="form-group">
        <label class="col-sm-3 control-label">Password</label>
        <div class="col-sm-6">
            <input type="password" name="txt_password" class="form-control" placeholder="enter password" />
        </div>
    </div>

    <div class="form-group">
        <label class="col-sm-3 control-label">Select Type</label>
        <div class=col-sm-3>
            <select class="form-control" name="txt_role">
                <option value="" selected="selected"> - Which one are you </option>
                <option value="admin"> Admin </option>
                <option value="parent"> Parent </option>
                <option value="swimmer"> Swimmer </option>
            </select>
        </div>
    </div>

    <div class="form-group">
        <div class="col-sm-offset-3 col-sm-9 m-t-15">
            <input type="submit" name="btn_login" class="btn btn-success" value="Login">

Just looking at your main HTML page I see that you don't have a destination for your form. You need an "action" attribute to give it a place to be submitted.
You also have method as POST but in the PHP file you are looking for GET.
Code:
if (isset ($_GET['btn_login'])) {

    $email = $_GET ["txt_email"];

$password = $_GET ["txt_password"];

$email = $_GET ["txt_role"];
Not sure if you close the if statement.
