$cart_item = $woocommerce->cart->get_cart(); 

I have the above code.

if I run print_r on cart_item I get a multi dimensional array:

Array(    [a6292668b36ef412fa3c4102d1311a62] => Array        (            [product_id] => 6803

How do I get the product_id only?

I tried $test = $cart_item['data'];

print_r($test);

Didn't work.

To get the product ID of each cart item in the foreach loop (for a simple product):

foreach( WC()->cart->get_cart() as $cart_item ){
    $product_id = $cart_item['product_id'];
}

If it's a variable product, to get the variation ID:

foreach( WC()->cart->get_cart() as $cart_item ){
    $variation_id = $cart_item['variation_id'];
}

Or for both cases (where $cart_item['data'] is the WC_Product Object in Woocommerce 3+):

foreach( WC()->cart->get_cart() as $cart_item ){
    // compatibility with WC +3
    if( version_compare( WC_VERSION, '3.0', '<' ) ){
        $product_id = $cart_item['data']->id; // Before version 3.0
    } else {
        $product_id = $cart_item['data']->get_id(); // For version 3 or more
    }
}

Update: Using Product ID outside the loop

1) Breaking the loop (Just to get the first item ID (product ID) of cart):

foreach( WC()->cart->get_cart() as $cart_item ){
    $product_id = $cart_item['product_id'];
    break;
}

You can use directly $product_id variable of the first item in cart.


2) Using an array of product IDs (one for each item in cart).

$products_ids_array = array();

foreach( WC()->cart->get_cart() as $cart_item ){
    $products_ids_array[] = $cart_item['product_id'];
}
  • To get the 1st item product ID: $products_ids_array[0];
  • To get the 2nd item product ID: $products_ids_array[1]; etc…

To check product categories or product tags in cart item use WordPress has_term() like:

foreach( WC()->cart->get_cart() as $cart_item ){
    // For product categories (term IDs, term slugs or term names)
    if( has_term( array('clothing','music'), 'product_cat', $cart_item['product_id'] ) ) {
        // DO SOMETHING
    }

    // For product Tags (term IDs, term slugs or term names)
    if( has_term( array('clothing','music'), 'product_tag', $cart_item['product_id'] ) ) {
        // DO SOMETHING ELSE
    }
}

We always use $cart_item['product_id'] as we get the parent variable product when a cart item is a product variation.

Product variations don't handle any custom taxonomy as product categories and product tags

Update: For WooCommerce 3.0+ Change cart item prices in WooCommerce version 3.0

You can use woocommerce_before_calculate_totals hook to customize your cart items prices.

You can define $framed_price variables as global in your function, this way.

This is the code:

// getting your additional price outside the function (making any conditional calculations) 
$framed_price = 20;

add_action( 'woocommerce_before_calculate_totals', 'add_custom_total_price', 10 );
function add_custom_total_price( $cart_object ) {

    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    global $framed_price;

    foreach ( $cart_object->get_cart() as $key => $value ) {
        $value['data']->price += $framed_price;
    }
}

Or get your custom price inside the hooked function (optionally, depending on how you get your custom price):

add_action( 'woocommerce_before_calculate_totals', 'add_custom_total_price', 10 );
function add_custom_total_price( $cart_object ) {

    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    $framed_price = 20;

    foreach ( $cart_object->get_cart() as $key => $value ) {
        $value['data']->price += $framed_price;
    }
}

This code is tested and working.

Naturally this code goes on function.php file of your active child theme (or theme) or in any plugin file.

Updated - You could use this 2 little snippets of code, that will:

  • Replace add-to-cart button/link in shop pages and archives pages (for non logged in users).
  • Avoid non logged in customers adding to cart and displaying a custom message.

Here is the code:

// Replacing add-to-cart button in shop pages and archives pages (forn non logged in users)
add_filter( 'woocommerce_loop_add_to_cart_link', 'conditionally_change_loop_add_to_cart_link', 10, 2 );
function quantity_inputs_for_woocommerce_loop_add_to_cart_link( $html, $product ) {
    if ( ! is_user_logged_in() ) {
        $link = get_permalink($product_id);
        $button_text = __( "View product", "woocommerce" );
        $html = '<a href="'.$link.'" class="button alt add_to_cart_button">'.$button_text.'</a>';
    }
    return $html;
}

// Avoid add to cart for non logged user (or not registered)
add_filter( 'woocommerce_add_to_cart_validation', 'logged_in_customers_validation', 10, 3 );
function logged_in_customers_validation( $passed, $product_id, $quantity) {
    if( ! is_user_logged_in() ) {
        $passed = false;

        // Displaying a custom message
        $message = __("You need to be logged in to be able adding to cart…", "woocommerce");
        $button_link = get_permalink( get_option('woocommerce_myaccount_page_id') );
        $button_text = __("Login or register", "woocommerce");
        $message .= ' <a href="'.$button_link.'" class="login-register button" style="float:right;">'.$button_text.'</a>';

        wc_add_notice( $message, 'error' );
    }
    return $passed;
}

Code goes in function.php file of your active child theme (or theme) or also in any plugin file.

Tested ad works.

Updated for WooCommerce version 3 and above

Since WooCommerce 3, get_variation_description() is now deprecated and replaced by get_description() WC_Product method.

To get your product item variation description (filtering variation product type condition), you can use the following hooked function instead:

// Cart page (and mini cart)
add_filter( 'woocommerce_cart_item_name', 'cart_item_product_description', 20, 3);
function cart_item_product_description( $item_name, $cart_item, $cart_item_key ) {
    if ( ! is_checkout() ) {
        if( $cart_item['variation_id'] > 0 ) {
            $description = $cart_item['data']->get_description(); // variation description
        } else {
            $description = $cart_item['data']->get_short_description(); // product short description (for others)
        }

        if ( ! empty($description) ) {
            return $item_name . '<br><div class="description">
                <strong>' . __( 'Description', 'woocommerce' ) . '</strong>: '. $description . '
            </div>';
        }
    }
    return $item_name;
}

// Checkout page
add_filter( 'woocommerce_checkout_cart_item_quantity', 'cart_item_checkout_product_description', 20, 3);
function cart_item_checkout_product_description( $item_quantity, $cart_item, $cart_item_key ) {
    if( $cart_item['variation_id'] > 0 ) {
        $description = $cart_item['data']->get_description(); // variation description
    } else {
        $description = $cart_item['data']->get_short_description(); // product short description (for others)
    }

    if ( ! empty($description) ) {
        return $item_quantity . '<br><div class="description">
            <strong>' . __( 'Description', 'woocommerce' ) . '</strong>: '. $description . '
        </div>';
    }

    return $item_quantity;
}

Now the description is just displayed between the title and the variation attributes values (if there is any).

Code goes in functions.php file of the active child theme (or active theme). Tested and works.

There are some missing arguments in your hooked function and you should need to make some changes to get the product Id this way:

add_filter( 'woocommerce_cart_item_name', 'just_a_test', 10, 3 );
function just_a_test( $item_name,  $cart_item,  $cart_item_key ) {
    // Display name and product id here instead
    echo $item_name.' ('.$cart_item['product_id'].')';
}

This code goes in function.php file of your active child theme (or theme) or also in any plugin file.

Tested and works.
