Error not clarifying what is keeping my program from parsing - php

Question

So I am running an error check, since my edit post function is not working, and this is the message I am getting
Fatal error: Uncaught mysqli_sql_exception: Unknown column 'trewfh' in 'field list' in C:\xampp\htdocs\Final\Forum\editpost.php:55 Stack trace: #0 C:\xampp\htdocs\Final\Forum\editpost.php(55): mysqli_query(Object(mysqli), 'UPDATE hw7_foru...') #1 C:\xampp\htdocs\Final\Forum\editpost.php(39): editpost(72, 'trewfh') #2 {main} thrown in C:\xampp\htdocs\Final\Forum\editpost.php on line 55
What a confusing error message! It is echoing out exactly what I want it to (the id =72 and the random string =trewfh) however nothing occurs in terms of updating my post. The $connectDB variable comes from including my connection file and universally works everywhere with no issues. I was hoping someone could see what I am not. Thanks for your time and assistance!!!
<?php
ini_set('display_errors', 1); ini_set('display_startup_errors', 1); error_reporting(-1); mysqli_report(MYSQLI_REPORT_ALL & ~MYSQLI_REPORT_INDEX);
include 'header.php';
include 'dbconnect.php';
//GATHER MY POST THAT MATCHES THE POST THE USER CLICKS TO EDIT AND DISPLAY TO THEM!
$sql = "SELECT forumpost_ID, forumpost_Text
FROM hw7_forumpost
WHERE forumpost_ID =" . mysqli_real_escape_string($connectDB, $_GET['eid']);
$result = mysqli_query($connectDB,$sql);
if(!$result){ echo 'Something went wrong, please try again later.'; }
else{
while($row = mysqli_fetch_array($result)){
echo'<form action="" method="post">';
echo'<div>';
echo'<textarea name="contents" rows="15" cols="50">'.$row[1].'</textarea>';
echo'</div><div>';
echo'<input type="submit" value="Add Post">';
echo'</div>';
}echo '</form>';
}
if(isset($_POST['contents'])){
$contents = trim($_POST['contents']);
editpost($_GET['eid'], $contents);
echo ('Your post has been updated!');
header('index.php');
die();
}
include 'footer.php';
/********************************************

function editpost($id, $contents){
global $connectDB;
$id = (int)$id;
$contents = mysqli_real_escape_string($connectDB, $contents);
$sql = "UPDATE hw7_forumpost SET forumpost_Text=".$contents." WHERE forumpost_ID= ".$id;
$result = mysqli_query($connectDB, $sql);
}
?>
My update should be saying hey database Update hw7_forumpost SET forumpost_Text = 'Trewfh' WHERE forumpost_ID = The correct id it's Getting via $_GET. Its reading everything fine like I said when it's echoing. Something random is happening along the way through

Answer 1

"UPDATE hw7_forumpost SET `forumpost_Text` = -->'<--".$contents."-->'<-- WHERE `forumpost_ID` = ".$id;
It was a simple case of forgetting to place a ' ' in between calling contents as David has pointed out. Thank you David!!!!
