使用PHP更新SQL数据

This is my second topic tonight, but it's only because I can't really find any helpful information in regards to updating data in SQL using php. For some reason this won't update. If anyone has any suggestions that would be great :), again sorry for asking another question, I'm just eager to learn from my mistakes.

HTML Section:

<html>

    <head>

        <title>Update Data</title>

        <meta charset="UTF-8">

        <meta name="viewport" content="width=device-width, initial-scale=1.0">

    </head>

    <body>

        <form action="editphpscript.php" method="post">

            ID To Update: <input type="text" name="id" required><br><br>

            New Status: <select name="status" required>
                <option>Status</option>
                <option value="Assigned">Assigned</option>
                <option value="Pending">Pending</option>
                <option value="No_Signal">No Signal</option>
                <option value="Installed">Installed</option>
            </select>



            <input type="submit" name="update" value="Update Data">

        </form>

    </body>


</html>

PHP Section

<?php
// php code to Update data from mysql database Table

if(isset($_POST['update']))
{

   $hostname = "";
   $username = "";
   $password = "";
   $databaseName = "";

   $connect = mysqli_connect($hostname, $username, $password, $databaseName);

   // get values form input text and number

   $id = $_POST['id'];
   $status = $_POST['status'];

   // mysql query to Update data
   $query = "UPDATE `leadlist` SET `status`='".$status." WHERE `id` = $id";

   $result = mysqli_query($connect, $query){

   ($result){
       echo 'Data Updated';
   }else{
       echo 'Data Not Updated';
   }
   mysqli_close($connect);
}

?>
