WooCommerce: Get & Return All Product IDs

When you work with WooCommerce PHP snippets, you often need to “get” stuff off your WooCommerce database in order to make some calculations and return the result on the screen. And if there is something I often google is “How do I get all my store’s product IDs?“.

Thankfully the get_posts WordPress function gives us the answer. In the next weeks we’ll also see how we can get other information, such as all SKUs, all product categories, etc.

So, here’s the quick snippet to return all product IDs on the Cart page (“woocommerce_before_cart” hook) – you can change that if you want to use them somewhere else. Enjoy ๐Ÿ™‚

WooCommerce: get all product IDs

PHP snippet: Get All WooCommerce Product IDs

/**
 * @snippet       Get / Return WooCommerce Product IDs
 * @how-to        Watch tutorial @ https://businessbloomer.com/?p=19055

 */

add_action( 'woocommerce_before_cart', 'bbloomer_echo_product_ids' );

function bbloomer_echo_product_ids() {
$all_ids = get_posts( array(
        'post_type' => 'product',
        'numberposts' => -1,
        'post_status' => 'publish',
        'fields' => 'ids',
) );
foreach ( $all_ids as $id ) {
        echo $id;
}
}

Where to add this snippet?

You can place PHP snippets at the bottom of your child theme functions.php file (before "?>" if you have it). CSS, on the other hand, goes in your child theme style.css file. Make sure you know what you are doing when editing such files - if you need more guidance, please take a look at my free video tutorial "Where to Place WooCommerce Customization?"

Does this snippet (still) work?

Please let me know in the comments if everything worked as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting on PHP 7+.
