Well lets start with the syntacitcal error…

            echo    "<input type=\\"button\\" name=\\"btnAddToCart\\" value=\\"Add To Cart >\\" onClick=\\"window.location.href='<?php echo $cart_url;?>';\\" >";

You dont need the <?php echo … ?> bits when you’re already inside PHP and already echoing.

            echo    "<input type=\\"button\\" name=\\"btnAddToCart\\" value=\\"Add To Cart >\\" onClick=\\"window.location.href='".$cart_url."';\\" >";
