How to make a variable to show the same row as it is currently showing in PHP?

I really don't know how to explain this question. But, I'm trying to make a product page that shows the same row as it is currently showing (so example "go onto a tech product page and at the bottom it shows all other tech related products").

Here is what I've tried:

<?php 
    $pType = $row['typeP'];
    $sql = "SELECT * FROM products WHERE type=$pType";
    $result = mysqli_query($con, $sql) or die(mysqli_error($con));

    while ($row = mysqli_fetch_array($result)){ 
    echo "<a href='products.php?id={$row['productID']}'>";
    echo "<img src='uploads/{$row['displayIMG']}'>";
    echo "</a>";
    }
?>
