Posts Aren't Showing in PHP - php

Question

I've been stuck on this for two days now. I have set up my own blog and the posts are stored in a database. This page is for grabbing an old post based on it's ID. When I try to retrieve them, everything shows but the actual body.
This is the index in /posts/
<?php
include_once('grabPost.php');
$TEMPLATE_TITLE = "$POST_TITLE";
include_once("../inc/template.html");
?>
Then, this is the grabPost.php.
<?php
error_reporting(-1);
$ID = $_GET['id'];
include_once('connectionMod.php');
$DBConnection = new MySQLi($DB_HOST, $DB_USER, $DB_PASS, $DB_DTBS);
function ReturnError($error){
global $POST_TITLE;
global $POST_BODY;
global $TEMPLATE_CONTENT;
$POST_TITLE="Oops!";
$POST_BODY="<p>It looks like we had an error grabbing your post. The post may have been moved, deleted, or you may have an invalid link. If you <strong>know</strong> this shouldn't be happening, please contact a developer.<br><em>$error</em></p>";
$TEMPLATE_CONTENT = "<h1>$POST_TITLE</h1>\n<hr size='2'>\n$POST_BODY";
}
if($ID == null){
ReturnError("No post ID was provided.");
}
if($stmt = $DBConnection->prepare("SELECT `Title`, `Poster`, `Date`, `Body` FROM `posts` WHERE `ID`=?")){
if(!($stmt->bind_param('i', $ID))){
ReturnError($stmt->error);
}
else if(!($stmt->execute())){
ReturnError($stmt->error);
}
else if(!($stmt->bind_result($POST_TITLE, $POST_NAME, $POST_DATE, $POST_BODY))){
ReturnError($stmt->error);
}
else if(!($stmt->fetch())){
ReturnError($stmt->error);
}
else{
$TEMPLATE_CONTENT = "<h1>$POST_TITLE</h1>\n<small>Posted on $POST_DATE by $POST_NAME</small>\n<hr size='2'>\n$POST_BODY";
}
}
else{
ReturnError($DBConnection->error);
}
?>
Oddly though, you can see the most recent post without issue on the homepage. Any suggestions with what's wrong?
Also, ReturnError() never shows the error. What can I do about it?

Answer 1

Function
function return_error($error){
$post_error = "<h1>Oops!</h1>\n<hr size='2'><br />"
."<p>It looks like we had an error grabbing your post."
."The post may have been moved, deleted, or you may have an invalid link."
."If you <strong>know</strong> this shouldn't be happening, "
."please contact a developer.<br><em>".$error."</em></p>";
return $post_error;
}
Usage:
/* check connection */
if ($DBConnection->connect_errno) {
$error = return_error("Connect failed: %s\n", $DBConnection->connect_error);
echo $error;
die();
}
/* check prepare() */
$stmt = $DBConnection->prepare("SELECT ....FROM `posts` WHERE `ID`=?");
if(!$stmt){
$error = return_error("prepare failed()".$stmt->error);
echo $error;
die();
}
and so forth ... By the way if connection fail or any other fatal error occurs, then die() or exit() is the right thing to do..

Well, I found the fix. I needed to run $stmt->store_result() before $stmt->bind_result() since since the body was a LONGTEXT, I guess this is some issue with MySQL and PHP.
