Answer 1

It looks like you were trying to pass $value into your url which won't work for two reasons.

1. You didn't echo this value in PHP so you're literally just passing the string $value. Looks like you're trying to pass the 'Brand' along so you'll need to make sure your url query parameter is 'Brand=$value["Brand"]' and not just $value.

2. $value is an array and you cannot pass an array into the url like you are trying to do.

<a href="product.php?post=Reference&Brand=<?php echo $value["Brand"]; ?>"> <h3 id="custompage"><?php echo $value["Brand"]; ?><span><br><?php echo $value["Reference"]; ?></span></h3></a>
