PHP Explode and updata data to each colomn in mysql database - php

Question

I have a form where I want a user to upload one or more images. I've used only one file field for this. The issue is when I submit the form only the "itemImageOne" field will be update. But the echo part( echo $pieces[0], echo $pieces[1] ) is shows the correct result. Bellow is part of my code.
<?php

Try
UPDATE module_course
SET itemImageOne = $imageOne, itemImageTwo = $imageTwo
WHERE id = '1'; # Changed
Changed - Edit 01
$stmt = $DB->prepare("UPDATE module_course
SET itemImageOne = ?, itemImageTwo = ?
WHERE id = 1");
$stmt->bindValue(1, $imageOne, PDO::PARAM_STR);
$stmt->bindValue(2, $imageTwo, PDO::PARAM_STR);
$stmt->execute();
Error Bcz of you are binding one parameter $stmt->bindValue(":img", $filename);
