I think you need a semi colon at end of $stmt=$db->stmt_init()
 
$stmt=$db->stmt_init();

I have solved my issue.
In index.html I changed the previous button to display:none
<!-- Previous Button --> <button id="prev-btn" style="display:none;"> <i class="fas fa-arrow-circle-left"></i> </button> And then in main.js I added
if(currentState == 1){ prevBtn.style.display = "none"; } underneath the Business Logic section. I also add the display inline or none in 2 places in each of the goNextPage function and the goPrevPage function so they now look like this:
function goNextPage() { if(currentLocation < maxLocation) { switch(currentLocation) { case 1: openBook(); prevBtn.style.display = "inline"; paper1.classList.add("flipped"); paper1.style.zIndex = 1; break; case 2: paper2.classList.add("flipped"); paper2.style.zIndex = 2; break; case 3: nextBtn.style.display = "none"; paper3.classList.add("flipped"); paper3.style.zIndex = 3; closeBook(false); break; default: throw new Error("unkown state"); } currentLocation++; } } function goPrevPage() { if(currentLocation > 1) { switch(currentLocation) { case 2: closeBook(true); prevBtn.style.display = "none"; paper1.classList.remove("flipped"); paper1.style.zIndex = 3; break; case 3: paper2.classList.remove("flipped"); paper2.style.zIndex = 2; break; case 4: openBook(); nextBtn.style.display = "inline"; paper3.classList.remove("flipped"); paper3.style.zIndex = 1; break; default: throw new Error("unkown state"); } currentLocation--; } }  

you are confusing
customer_id = :id;
for
customer_id = :customer_id;

if I understand correctly this should work.
echo "<div class='field-container'>"; if($game['platform2'] !== ""){ echo "<div class='title'>Platform</div> <div class='information'>{$game['platform2']}</div> <div class='title'>Launcher</div> <div class='information'>{$game['launcher2']}</div>"; } echo "</div>";  

I ended up with this however I suppose a php memory issue will arise when enough data is retrieved.

 
$all_data = array(); foreach($id as $idkey => $iduse){ $temparr=array(); $result_time = $conn->query("SELECT * FROM ".$iduse." order by timedate Asc"); while ($rowtime = $result_time->fetch_row()) { $temparr[] = $rowtime; } array_push($all_data, array("id" => $idonly[$idkey], "comment" => $comment[$idkey], "data" => $temparr)); } Also thank you Barand for the fetch_row replacement.
