Getting value from dropdown list - php

Question

I'm trying to get the selected value from a dropdown list.
The list has name 'select_employee', when I press the button with name 'save' I hope to get the value. I'm using a POST to to get the value.
I get the error 'Undefined index: select_employee'.
<div class="form-group">
<h2>Enter Certified Course Details</h2>
<?php
// start of connect db
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "TrainingDB";
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
//end of connect db
?>
<form id="form" action="" method="post">
<?php
// Drop down list employee
$sql = "SELECT * FROM employees";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
echo "Select Employee<br>";
echo "<select name='select_employee' id='select_employee'>";
// output data of each row
while($row = $result->fetch_assoc()) {
echo "<option value='" . $row['id'] . "'>" . $row['fname'] . " " . $row['sname'] . " </option>";
}
echo "</select>";
echo "<br>";
}
?>
</form>
<?php
if(isset($_POST['save'])){
echo "save<br>";
$employee=$_POST['select_employee']; // error here
echo "Selected Employee" . $employee . "<br>";
}
?>
<form Employee="/employee_page.php" method="post">
<button type="submit" class="btn btn-primary" name="save" value="save">Save</button>
</form>
</div>

You are using two different form so make sure to use only one form.
