Why wont my form add to database after adding if(isset($_POST['save']))?

I have a form that adds records to a database. Every time I would refresh the page it added a blank record. I narrowed it down to the php file that executes the sql query. When I reload this php file in the browser it adds empty records. I've searched and I think it has something to do with if(isset($_POST['save'])) missing. 

I've enclosed the code inside the if(isset($_POST['save'])). It doesn't add records on reloads now, but when submitting the form it doesn't add anything to the database. The input submit is named "save". Here's the form code....

<form id="myform"  enctype="multipart/form-data" method="post" >
<p><label>Tracking Code<span style="color: red;">*</span> 
</label><br>
  <input type="text" id="code" name="code" required></p>

<p id="userhidden" style="display:none"><font color="#000000"> 
[swpm_show_member_info column="user_name"]</font></p>
<p><label>Username<span style="color: red;">*</span> 
</label><br>
  <input id="username2" type="text" name="username"  readonly 
required> 
</p>


<p><label>Address</label><br>
  <input type="text" name="address" id="address" placeholder="E.g. 
1313 
Mockingbird Ln."></p>

<p><label>City<span style="color: red;">*</span> 
</label><br>
  <input type="text" name="city" id="city" placeholder="E.g. 
Mockingbird 
Heights" required></p>

<p><label>State<span style="color: red;">*</span> 
</label><br>
  <input type="text" name="state" id="state" placeholder="E.g. 
California" required></p>

<p><label>Country<span style="color: red;">*</span> 
</label><br>
  <input type="text" name="country" id="country" placeholder="E.g. 
US" 
required></p>

<p><label>Note</label><br>
  <textarea name="note" rows="8" cols="40" placeholder="Write a note 
for 
all to read."></textarea></p>

<p><label for="file-select">Upload Photo of your duck:</label><br>
  <!-- <input type="file" name="upload" id="file-select"></p> -->
  <input type="file" name="uploadfile" value="" accept="image/png, 
image/jpeg"/><br><br>



<input  type="submit" value="Log Duck!" id="btnSendData" name="save" 
class="button button1" ><br />

</form>

Here is the php code...

<?php

//$_POST['save'] being the input submit with name="save"
if(isset($_POST['save'])) { 
$servername = "localhost:3306";
$database = "keljohns_duck_tracking";
$username = "keljohns_kelly";
$password = "Kjohnson5488!";
// Create connection
$conn = mysqli_connect($servername, $username, $password, $database);
// Check connection
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
echo "Connected to database successfully.";
//echo $_FILES["uploadfile"]["name"];


if(true)
{
$filename ="";

if (empty($_FILES['uploadfile']['name'])){
    $_FILES['uploadfile']['name'] = "default.jpg";
    $filename = $_FILES['uploadfile']['name'];
}
else{
    $filename = $_FILES["uploadfile"]["name"];
    $tempname = $_FILES["uploadfile"]["tmp_name"];
        $folder = "img/".$filename;


        if (move_uploaded_file($tempname, $folder))  {
            $msg = "Image uploaded successfully";
        }else{
            $msg = "Failed to upload image";
      }
}

    $code = ($_POST['code']);
    $username =  ($_POST['username']);
    $address =  ($_POST['address']);
    $city =  ($_POST['city']);
    $state =  ($_POST['state']);
    $country =  ($_POST['country']);
    $note =  ($_POST['note']);
    $date=date("Y-m-d");


$sql = "INSERT INTO ducks (code, username, address, city, state, country, upload, note, date)
      VALUES ('$code','$username','$address','$city','$state','$country','$filename', '$note', 
'$date')";

if (mysqli_query($conn, $sql)) {
  echo "";
} else {
  echo "Error: " . $sql . "<br>" . mysqli_error($conn);

}

mysqli_close($conn);
}
//  }

}
?>

What I have tried:

First it was inserting blank records into the DB. After I added the if(isset($_POST['save'])) line it doesn't add anything to the DB now.
