How do I retrieve a td value in PHP based on the row of the submit button pressed?

I would like to being able to see a td value based on the row that a 'submit' button is in. enter image description here

Here is my html code 

<?php foreach($books as $booklist) : ?>
        <tr>

            <form action = "." method = "post">
            <input type="hidden" name="action" value="addtocart" >
            <td><img height="50" width="50" src=<?php echo "/../../product_manager/uploads/".$booklist['productimage']; ?>></td>
                    <td><?php echo $booklist['name']; ?></td>
            <td><?php echo $booklist['version']; ?></td>
            <td><?php echo $booklist['releaseDate']; ?></td>
            <td><?php echo $booklist['price']; ?></td>
            <td><?php echo $booklist['quantity']; ?></td>

            <td><input name="submit" type="submit" value = 'Add to cart'/><td>
            </form>

        </tr>
        <?php endforeach; ?>

And here is my controller

 if($action == 'addtocart'){

echo $booklist['name'];
}

My problem is that it is echoing the last row only. If I echo version, price etc, it only echos the product named test. How can I get it to echo based on the submit button row? Also I'd like to keep it strictly php or html only.

You can give the submit button an array based name such as name="submit[0]". That way you can use a counter variable in your loop to assign the value to the submit button and determine which button was pressed.

The above is my recommendation which you should use with a single form element. According to the HTML standards, a form should not be contained in a tr element, only in a td element. Therefore your form element should be contain your table and not the other way around.

Instead of a for loop, you can also try reading the value as:

$arr = array_keys($_POST['submit']);
echo $arr[0];
