One column isn't updating in table

Question

I am trying to update a table in my database. It looks up a row via a HogId number, and updates the row. All columns will update but the PetName column. I checked and the variable is set, the HogId is correct and all columns match the table. What am I missing? I am not done yet, as I haven't done some security stuff to do as well.

<?php
session_start();
require_once('../mysqlconnect.php');

//ini_set('display_errors', 1);
//ini_set('display_startup_errors', 1);
//error_reporting(E_ALL);
?>

<?php

if(isset($_SESSION['HHAdminUserId'])&&isset($_SESSION['HHAdminName'])){
