WooCommerce – Check if product is already in cart

Thank you so much for this code.

In my case, I’m using WP_Query to display a selection of products on my homepage. To generate the Add to Cart button, I’m using do_shortcode in my template. It works, but not with the code above.

I modified the first filter to use woocommerce_loop_add_to_cart_link (instead of single_add_to_cart_text), and while that did indeed alter the text of the Add to Cart button, it rendered as *just* text, i.e. not a button (not even a link).

Do you have any advice on how to proceed?

Thank you!

Hi Remi

I’ve copied and pasted the code exactly how given into functions.php and it works great on the single product page but seemingly not on any other page, i.e. the shop or category pages. I’m not using any other plugins that would edit the default Woocommerce markup or text.

Is there an update to this code we need to use instead since Woocommerce 2.1 has been released?

Thank you =)

Hi There,

Great snippet!

Is there anyway we can get this to work with ajax?

Thanks again!

Hi Remi,

Useful code snippet. Working fine. Is there any possibility to change the Already in cart button to unclickable or disabled?

Thanks,
Saran

Hello Remi,

This is a wonderful post. I want some changes with this snippet as per my requirements.
I want change the ADD TO CART button text to ADDED when the item is in cart.
otherwise check the product tag, if the product tag is “buynow”, the ADD TO CART button text will be BUY NOW, else it will be ADD TO CART. I used if ( has_term( ‘buynow’, ‘product_tag’, $_product->id ) ). but I am going with some logic error. Can you please help me

Here is my code:

/**
* Change the add to cart text on single product pages
*/
add_filter(‘woocommerce_product_single_add_to_cart_text’, ‘woo_custom_cart_button_text’);
function woo_custom_cart_button_text() {
global $woocommerce;
foreach( WC()->cart->get_cart() as $cart_item_key => $values ) {
$_product = $values[‘data’];

if( get_the_ID() == $_product->id ) {
return __(‘Added’, ‘woocommerce’);
}
}

if ( has_term( ‘buynow’, ‘product_tag’, $_product->id ) ) :
return __( ‘Buy Now’, ‘woocommerce’ );
else:
return __( ‘Add to Cart’, ‘woocommerce’ );
endif;
}
/**
* Change the add to cart text on product archives
*/

add_filter( ‘woocommerce_product_add_to_cart_text’, ‘woo_archive_custom_cart_button_text’ );
function woo_archive_custom_cart_button_text() {
global $woocommerce;
foreach( WC()->cart->get_cart() as $cart_item_key => $values ) {
$_product = $values[‘data’];

if( get_the_ID() == $_product->id ) {

return __(‘Added’, ‘woocommerce’);
}
}

if ( has_term( ‘buynow’, ‘product_tag’, $_product->id ) ) :
return __( ‘Buy Now’, ‘woocommerce’ );
else:
return __( ‘Add to Cart’, ‘woocommerce’ );
endif;
}

Hi Remi,

Thanks for your post. I get a similar problem that is related to the one you talk about. As I sell digital products, I cannot uncheck the “Enable this to only allow one of this item to be bought in a single order” option because I don’t want customers to buy 2 times the same digital product and having to refund them.

The problem occurs when a customer do not checkout right now, go back to the site, and then change his mind and click another time on the “buy” button. As I sell digital product on landing pages, I skip the cart to simplify the process, but in these situations the customers get the “You cannot add the X product in your cart” instead of going back to the checkout page for that single digital product.

Is there a way to simply “re-add” the single digital product (with the option “allow one of this item to be bought in a single order” activated) and get the customer to the cart instead of giving the “You cannot add the X product in your cart” message?

Thanks!
