'false' returns on all calls for a product

Question

I am getting bool(false) as a return making calls for a product, using the product ID. Depending on which code I use, I have also had NULL and 0 returns but never any product data.

I have tried...

$_pf = new WC_Product_Factory();
$product = $_pf->get_product($id);

$_pf = new WC_Product_Factory();
$product = $_pf->wc_get_product($id);

$product = new WC_Product('1651');

I have even tried calling all the way back to WC()->.

I have tried the above code in functions.php. I am also having issues with the child div file not over riding the parent div file, so I have placed this code in the parent div file. That issue is for another time, I just need to get a simple call to the product to go through.

<script>
    function getAJAX() {
        jQuery.ajax({
            type: "post",
            url: "/wp-admin/admin-ajax.php",
            data: "action=get_Title&id=1651",
            success: function (data) {
                console.log(data);
            }
        });
    } // End function for getAJAX.
    var button = document.getElementById("ajax_button");
    button.addEventListener("click", getAJAX);

</script>

This is the AJAX call from the template, content-single-product.php. I do not think there is any issues here. I am getting data returned.

add_action("wp_ajax_get_Title", "get_Title");
add_action("wp_ajax_nopriv_get_Title", "get_Title");

function get_Title() {
    $id = $_REQUEST['id'];
    $_pf = new WC_Product_Factory();
    $product = $_pf->get_product($id);

    echo $product;

    die();
}

Above is some code I have been using to test. Last thing I tried and still getting bool(false).

Yes, that is a valid product ID. I was just testing out connecting to a product and pulling out the title, or something, before I start coding for all the pieces of data I need to pull from the product.

This is a multi-site platform, and the AJAX calls and calls to woocommerce products are working on other pages within the very site I am working on, but will not pull anything on the project I am working on.

I am very new to woocommerce and WP, so any help here is greatly appreciated.

I don't have an extra WC instance around to try on but I do see one possible issue.

$_REQUEST['id'] is a string (always). WC_Product_Factory->get_product() may very well be expecting an int. PHP is not, and WP definitely is not, always clever about transparent recasting.

Try this to see if it helps:

function get_Title() {
    $id = $_REQUEST['id'];
    if (is_string($id) && is_numeric($id))
        $id = intval($id);
    $_pf = new WC_Product_Factory();
    $product = $_pf->get_product($id);

    echo $product;

    die();
}

Unable to test I can't diagnose if that's really what's going on but it's a quick change so it's worth trying.
